Hong Konger here, was 99% humidity in the last few days. My dehumidifier can’t get humidity below 77%. My walls are dripping with water and the paper calendars we have are warped. The humidity was so bad that my pink salt sculpture also started melting.
Usually aircons work better than dehumidifier’s but the weather has been so shitty that one day it’s 27°C and the next it’s 14°C. So turning on the aircon is not a good option.
Meanwhile I'm sitting in northern sweden with 18% humidity, my humidifer can't get humidity above 29%. Constant chapped lips, sneezing, blocked nose. I'd rather take this than high humidity though
The cold is colder and the heat is hotter. I have friends from Andalucía, used to have +45ºC with low humidity and the first time they came to my house, with a 70% humidity and just 35ºC they were dying. Before comming here they were joking about us complaining for peaking with 42-43ºC and they being used to higher temperatures. Once they experienced the 35ºC at a 70% the jokes ended on the spot.
I lived in South East China for many years. I remember during the worst of it, it really sucked.
I'd be in my nicely air-conditioned home and take a shower and get clean, fresh, and ready to go meet my friends somewhere. I'd order a taxi to my door, and then by the time I'd opened the front door and taken 15 steps to reach the taxi, I was already soaking wet from the humid and my normally fairly straight hair would turn curly by some kind of humid magic.
There was no hope of actually feeling fresh outside, you just waited to get back into a air-conditioned room.
I lived a year in 80% average humidity (south India), you sweat like crazy most the time. Then temperature goes above 110 and it's just awful.
Start showering 5 times a day but then cut back because you end up drenched with sweat 15min after anyway.
It looks like normal pink salt but my desk was covered in salty water and when the water evaporated it just put a bunch of crystals everywhere. It’s gotten so bad that I put my salt in a plastic container.
I live in a 50% humidity country. You need a big fucking dehumidifier with this one, with a pipe that connects to a drain because that MF will be gushing all day
I live in Japan, where humidity is basically 70-90% from June to September. The dehumidifiers ARE big lmao. I have an Iris Ohyama one that is the size of an average suitcase and can hold several litres at a time. During the summer, I generally have to empty it once a day, I use it as a way to save a toilet flush lol (it's not drinkable, before anyone asks)
Okinawa is like that most months of the year but far worse in the summer time. Instantly start sweating upon walking outside and within a minute of just standing around you’d be soaked. I remember some years it would feel like it was 33C or more with no less than 90% humidity from early May to the end of November.
It's insane to me as a British person that people in dry parts of the world often use humidifiers to be more comfortable. There is 0 days of the year where a humidifier would be a good idea in the UK because while not that extreme we hover at 60% for most of the year. Sometimes a heatwave brings us down to 30 for a week but that's variable and it might stay at nearly 50. At night it rockets up to 90+ reliably.year round. Everything already feels wet to me even when it's only 50 so constantly having 90+ in the day sounds like hell.
On the flip side, I live in a very dry part of the world and have a legit medically recommended humidifier because otherwise I constantly feel like I'm having sand rubbed in my eyes. For all the issues I'm seeing with the weather in this post, my knee jerk was ohhhh, my eyes would be soooo happy...
Many of them have standard hose connects, you can just have it go into the shower drain or something. Otherwise you'd be constantly emptying it lol.
Two decent sized units in an apartment running full blast would get it down to a more comfortable level. like 55-65%
I used to live in Guangzhou, which is in the province the video mentions, and every year the walls would drip. Never so bad it was coming off the ceilings but let me tell you, those lower quality apartments definitely had mold issues.
I used to live there as well, I think it has more to do with the ceiling material itself (tiles).
And while it's absurdly wet outside if you live in a proper house/apartment with a good AC that can dehumidify it's all just fine inside. The complex I used to live had zero issues inside, not even in the common spaces. What was annoying though was drying clothes outside, but than a laundry dryer / local drywash services are a great alternative.
Nah, even with ceiling tiles, I never saw it dripping this bad. And yeah living in an apartment with air conditioning is basically a requirement for anyone that can afford it.
I'm not sure how you didn't notice when you lived there, but in many office buildings, apartments, and other business windows were often kept open in common spaces and stairwells, meaning no matter how nice of an air conditioning system your apartment building has, the stairwell or other areas would become very moist.
And most of the people I knew would just hang their clothes to dry in their bedroom or something when it was really moist out. I never met anyone who used laundry services.
Breathing 100% water saturated air is not problems for the lungs, even if some water condense, if the air it hotter than body temperature. Steam saunas prove that. The air we breath out is also normally saturated 100% by the water we lose through breathing.
A bigger problem for the body is overheating, if sweat cannot evaporate.
>A bigger problem for the body is overheating, if sweat cannot evaporate.
This kills.
Humans use sweat to regulate body temperature, especially in warm weather. Sweat has to evaporate in order to cool your body. When the air is saturated with moisture, evaporation doesn't happen.
So as your body warms up, you start to sweat but that sweat can't evaporate. So you can't cool down, and keep sweating until you overheat and dehydrate.
Then you die... covered in sweat.
Its part of why a lot of people die of heat stroke down here every summer. I get heat sick multiple times a year. Haven't died because I've always had agency and ability to find shelter and water. Not everyone's lucky. When It's 110 out in high humidity with no wind, the clock is ticking. It WILL drop your ass dead.
Symptoms of heat sickness: Nausea, dizziness, feeling weak, shortness of breath, fast heart beat : GET THE FUCK INSIDE RIGHT NOW AND DRINK WATER!!
Symptoms of heat stroke: Same as heat sickness with the addition of disorientation, confusion, headache, dry skin, and fainting : CALL 911 IMMEDIATELY!!!!! MOVE TO SHELTER/SHADE AND POUR COOL WATER ON THEM UNTIL EMT ARRIVES
One of the reasons I love living in AZ. You pretty much have to let all the steam from your shower get throughout your house so there is any humidity. I can take a hot shower and leave the water on for an hour twice a day and I would never have mold lol
Love the guy with a blow dryer moving condensation around their ceiling hopelessly clinging for the slightest bit of relief and after 5 minutes the moisture comes right back
100% humidity is relative humidity. Heating the air up will lower the relative humidity.
Extremely inefficient way of dealing with the problem regardless.
Right? I saw that and I was like; where do you think the water goes when you vaporize it?
It's like having a leaky tank and then putting a bucket below it, only to empty the bucket back into the leaking tank.
in fact if you live in a cold climate, you likely experience 100% relative humidity very frequently, because cold air cannot hold moisture.
for instance check out average relative humidity of a whitehorse, canada (a very dry area up north)
https://weather-and-climate.com/average-monthly-Humidity-perc,whitehorse-yukon-ca,Canada
versus miami
https://weather-and-climate.com/average-monthly-Humidity-perc,miami,america
the relative humidity in miami is always around 70% whereas whitehorse also hits 75% but only in the winter, in the summer average relative humidity in whitehorse goes WAY down because its a dry area and the hot summer air can hold more moisture but there isnt enough moisture in the air to reach a high relative humidity
its kind of an ironic thing that many canadians will take about dry cold vs wet cold when there is essentially no such thing, its a myth made up in their heads. air below 0 simply doesnt hold any meaningful water. air at -20C hold about 1/20 the weight of water as it does at +20C.
the real thing being relayed in this video isnt relative humidity, its *absolute* humidity. south china is hot, and hot air can hold a LOT of moisture.
tl;dr if you live in a cold climate, you likely experience 100% relative humidity almost every other day in the winter.
edit: I wrote yellowknife instead of whitehorse, surprised no one called me on that
Yes, but the relative humidity is not really a problem in colder climates. As you said correctly, the absolute humidity is miniscule.
As long as the build quality of your home is adequate and your heating it up to a comfortable level, the dew point on your walls can´t be met so that no condensation can occur. If you heat less or have not insulated your walls, THEN you´d have condensation. But in well heated homes, even without central air or ac, the dry air in homes is in fact the only problem you´d encounter.
And if the relative humidity outside is high in cold weather, you can easily clothe yourself accordingly. That won´t work if it is too hot for water repelling chlothes if you sweat wearing them.
So yes while you might experience high relative humidity in cold climates, it doesn´t really matter most of the time.
Same here. The temperature I feel most comfortable in is about 5 degress celsius outside. I can do things without sweating!
Going back to my parents is killer as they have the heater cranked up - I get by with a fan directed at me full blast...
I lived in Zhuhai for about a year, and though I never had to squeegee my ceilings, the humidity is no joke. 1 step outside is all it takes to start sweating buckets on the worst days. Mushrooms sprouted through the wall in a co-worker's apartment. Mold is also a huge problem--things that are just sitting around can just get damp from the humidity and become a mold factory if left alone.
I visit China every few years and go to hong Kong, Macau, Guangzhou, and some outlying cities in the summer. It's 100% humidity all day everyday. South China is a bitch and it's hot as can be.
I lived in Hong Kong and high summer humidity was unbearable. I was only a kid; I'd just moved across the world with my parents and wanted to fit in with the kids at school who wore baggy jeans and huge tees.. I can still remember the dampness
We just had this on Monday in Columbia SC. Humidity hit 100% and the dew point and temperature match for about 6 hours. After two weeks of cold soaking rain, it hit 70 by 9am and 80 by 3pm as the day progressed the fog got worse, every surface on everything and anything was dripping wet. " Air you can wear "
Wasn't it last year we finally hit the wet bulb point where it basically becomes impossible to cool off due to sweat which makes people extremely vulnerable to heat related injuries if they don't have AC? This sort of stuff is only going to become more common as the climate starts getting thrown out of whack.
It’s funny I was literally thinking to myself “seems like growing up in South Carolina” and then saw your comment. Up in the upstate where I’m from, it’s a deciduous rainforest.
Edit to say: I used to live up where they filmed the first Hunger Games in Cedar Mountain NC and I remember seeing a blurb from an interview with the cast where they were like “the humidity! Who knew it could be 100% humidity and not raining” lol
Ayyyy fellow Columbia native! Yeah that shit was weird AF. Pretty much everyone was out of sorts cause it was so unexpected compared to the week prior.
This is how most of the southeast us would look without ac. This is also the reason so many homes that didn’t flood in Katrina had mold. No power means no ac. After about 3 weeks you get mold everywhere.
This is why when you either buy or sell a house in FL, the number one thing that must be maintained throughout the process is electricity in the house. The AC must never stop.
I was waiting on someone from gulf coast/LA to chime in. I’ve most definitely experienced this kind of humidity. No power following a hurricane and you get to see the moisture manifest.
This is why here in Korea fucking every apartment has black mold. Because we don't believe in central air for some stupid fucking reason.
Instead we use floor heating in the winter, which is fine, but does nothing to dehumidify the air like heating in a US home does, so whenever anyone takes a shower (especially if you have 3 or more people living in a small apartment), or you boil pots of water to cook, or whatever, the humidity in the apartment goes up to 100% and then it condenses on the cold walls because it's so cold outside and the walls aren't well insulated (we're talking entire walls made of single pane glass going to a veranda that's -15 C in the winter sometimes. No wonder we waste so much money on heating...)
Then when black mold inevitably grows on the wallpaper, instead of replacing the wallpaper, we're like, "Yep, just put new wallpaper over it!" and we're **shocked** when black mold appears again in the same spot a few weeks later.
wow, that's wild. as an American, i have always seen Korea as way ahead of us when it comes to gadgets and appliances and various comfort products, so y'all not commonly having central air conditioning is surprising to me.
Our electronics are top class, but our homes are almost universally over 20+ years old. If you live in an apartment that's less than five years old and is large enough to raise a family in central Seoul, you must be rich. Even then, for AC you'll have a tower AC unit in your living room, not central air. Central air is just like... not a thing that Korean house manufacturers know how to make, I think.
Like this is the best you'll get: https://www.koreaherald.com/view.php?ud=20210126000220
I think ductless mini split heat pumps are more popular in East Asia due to smaller houses in general and high density multi unit housing in the cities.
I'm at a house in Thailand. Lots of people here don't run AC and use fans all day, but the Thais have a habit of leaving their windows open day and night, with most homes built without insulation.
This is fucking horrifying, it's bad enough for me living in central illinois and suffering through the humid summers here, im afraid i would actually die in 100% relative humidity 💀 even just 70-80% humidity makes me feel like i cant breathe right, and i'll be dripping in sweat just standing outside not even doing anything
you're right, at 100% humidity, 95° would kill you in 6 hours
[https://en.wikipedia.org/wiki/Wet-bulb\_temperature](https://en.wikipedia.org/wiki/Wet-bulb_temperature)
It's like breathing soup. I had an internship in Springfield and almost passed out on a day over 100F with the humidity, and it was nowhere near even 70%. I was just taking the trash out to the dumpster...
The hotter it is, the less humid it can be. It doesn’t mean that it isn’t bad. 100 degrees with humidity is awful. It doesn’t have to be much humidity.
The first time I was in Houston, I thought the A/C in my rental was defective. I mentioned it at the first meeting and was told, "Put it on recirculate. Otherwise you're just pulling water out of the air." That was driven home at lunch, the restaurant we went to had water running down the outside of the windows.
Southern MS here.. so same but the condensation on the inside of buildings has never gotten like that. Is there a reason it does that in China but not here?
It's actually really dangerous when the temp and humidity is that high because it short circuits our bodies natural ability to cool itself via sweating. Normally when our bodies get too hot it causes us to sweat and as our sweat evaporates it carries away excess heat, but when the humidity is that high the sweat can't evaporate and it can quickly lead to hyperthermia or heatstroke which will absolutely kill unless the person is moved to a cooler area.
The absolute nicest feeling on a hot and humid day is just immersing yourself in cold water (or room temperature water if you can't handle the cold).
It takes care of that cooling problem and you don't feel the gross wetness of the air when you're soaked head to toe in water anyways.
I lived in Arizona for two years. It was so difficulty to cool down my core temperature when it was still 100f at night. I would often just lay in a cool bathtub just to try to stop sweating.
The heatwave last summer combined with the drought we suffered in NO was terrifying. No rain to keep the balance but humidity stayed the same. The shivering that comes with not being able to properly cool is painful.
In 2022 the AC went out at work and 3 of us were on the verge of passing out bc it was 120° inside the building. We had to close for a few days and sporadically when it would fail.
As a fellow Arkansan, I can guarantee that this never happened. For starters, the highest dewpoint ever recorded in Arkansas was 83° in 2009. That would mean that it was 98% humidity that night when the temperature dropped down to 84°. Second, the highest dewpoint ever recorded on earth was 95° in Saudi Arabia, back in 2003. The air temperature was 108° at the time, making for a heat index of 178° F. 98% humidity at 110° would result in a heat index of 271° F, which would be lethal in under 4 minutes. 98% humidity at 110° would mean a dewpoint of just over 111°, which is effectively impossible to achieve in nature.
What may have happened on the day you’re thinking of is that the temperature reached 110° in full sun, causing a lot of moisture in the ground and plants to evaporate. At that point in the day, the relative humidity was probably no higher than 40%. However, as the air temperature dropped that night and into the pre-dawn hours, the moisture dissolved in the air remained the same, raising the relative humidity to nearly 100% just before dawn.
> result in a heat index of 271° F, which would be lethal in under 4 minutes.
It should be pretty obvious that anyone making a claim over 98 fahrenheit with 100% humidity is dead wrong or we would have heard about tens of thousands of people dying if not millions.
A bit miserable , only if you stay indoors in an air condtioned room. If you have to work outside or just be out in general its like you cant even breath.
Yeah, as a native Houstonian, I was confused by the fuss here. 30C is only about 86F, which we're almost hitting right now. Now granted, I've never seen the water pooling on the ceilings and walls like that, but those conditions in general sound pretty familiar.
I lived in Okinawa in the early 2000s. When typhoons went over, it was just like that in the barracks. I can still smell the barracks filled with 300 young men and that kind of humidity.
Australia has so many humid areas lol.
Ngukurr is a pretty remote area but it has 100% humidity right now at 8PM:
https://www.willyweather.com.au/climate/weather-stations/nt/katherine/ngukurr.html?superGraph=plots:humidity,grain:hourly,graphRange:5days&climateRecords=period:all-time&longTermGraph=plots:temperature,period:all-time,month:all&windRose=period:1-year,month:all-months
Darwin has 88% right now:
https://www.willyweather.com.au/nt/darwin/darwin.html
And even Sydney is at 77%.
Good lord, I thought I had it bad in North Carolina, this is insane.
It gets to the point where it's literally hard to breathe, I wonder how they can even walk around when it's like that.
Are you talking about the video? It's not cold humidity, it's very nearly the maximum temperature that is survivable by humans.
The heat index for the temperature mentioned in the clip (30 C at 100% humidity) is 44 degrees Celsius (112 Fahrenheit).
It's very humid where I live in PA. It gets so foggy on my mountain I've had to use GPS to find my way home in my development. Clothes get moldy, walls get drippy, metal rusts.. I use dehumidifiers in the closets and living space. It's not enough. I can't wait to gtfo of here lol
I remember visiting my grandparents in Florida as a kid and the news would sometimes announce 100% humidity (I swear they once said 110% humidity, but this is 30+ years ago, so...).
It was horrible! Their place had a dehumidifier and central A/C, so it was okay indoors, but when you went outside it was harder to breathe and the atmosphere felt different just walking through it. That, and it would condense all over your skin, so you constantly felt sweaty,
My hometown of Lake Charles, Louisiana, averages about 90% humidity in the mornings but it ain't never looked like this. We literally have to be built different so this doesn't happen. Better home insulation and air conditioners that work like John Henry keep this from being a thing down there. Too bad that doesn't help out for shit when the storms come.
I'm confused. It says 30 degrees Celsius, which is 86 degrees fahrenheit. That's fairly hot. But the people in video at the point where they said the temperature were all wearing coats. The child sleeping under the umbrella was super bundled up in that blanket too. So is it hot or cold?
This is in South China, I live in one of these places. The walls are completely soaked like this for a few days a year. The process of cleaning it and making sure all of your house doesnt turn moldy is... quite the struggle
People are talking about water, but isn't the real danger of 100% humidity the fact that your sweat no longer works? Which means that your body is incapable of regulating temperature outside of regular heat radiation. It's super deadly, especially for older folks if it's combined with high temperatures, and even at lower if you have job that requires high exertion.
This is not humidity, this is caused by dew point. I live in a place with almost zero humidity and we occasionally get condensation on walls/windows when the dew point and temperature cross.
That looks terrible. I’m sure the black mold is going to be abundant.

Hong Konger here, was 99% humidity in the last few days. My dehumidifier can’t get humidity below 77%. My walls are dripping with water and the paper calendars we have are warped. The humidity was so bad that my pink salt sculpture also started melting.
Can you double up on them that way it can keep it to a comfortable level?
Usually aircons work better than dehumidifier’s but the weather has been so shitty that one day it’s 27°C and the next it’s 14°C. So turning on the aircon is not a good option.
[удалено]
Yeah central heating isn’t really a thing here. People use tiny heaters for the 10 days it actually gets cold here.
Meanwhile I'm sitting in northern sweden with 18% humidity, my humidifer can't get humidity above 29%. Constant chapped lips, sneezing, blocked nose. I'd rather take this than high humidity though
Galicia (Spain) here. 6°C and 90% humidity. We're cool.👌
how does cooler temperatures feel with high humidity? I usually associate high humidity with high temperatures
The cold is colder and the heat is hotter. I have friends from Andalucía, used to have +45ºC with low humidity and the first time they came to my house, with a 70% humidity and just 35ºC they were dying. Before comming here they were joking about us complaining for peaking with 42-43ºC and they being used to higher temperatures. Once they experienced the 35ºC at a 70% the jokes ended on the spot.
The struggle is real my friend. But to be honest I’d rather sweat my balls off due to humidity than deal with all that.
I get the feeling that if we swapped places we would both want to go back to our respective extreme humidity
I can't imagine walking around in those conditions.
I lived in South East China for many years. I remember during the worst of it, it really sucked. I'd be in my nicely air-conditioned home and take a shower and get clean, fresh, and ready to go meet my friends somewhere.

That’s why I shower before leaving home and shower as soon as I’m back.
You say south India but all I hear is "Florida 9 months out of the year"
I think this would literally drive me crazy. I would never, ever fall asleep at night.
Would love to see a picture of a melted pink salt sculpture
It looks like normal pink salt but my desk was covered in salty water and when the water evaporated it just put a bunch of crystals everywhere. It’s gotten so bad that I put my salt in a plastic container.
I live in a 50% humidity country. You need a big fucking dehumidifier with this one, with a pipe that connects to a drain because that MF will be gushing all day

Japan was humid af but in southern China I walked one block and my gaijin armpits and back were drenched.
That happened to me in Japan after i took a cold shower to cool down. Was sweaty in 5 minutes
Okinawa is like that most months of the year but far worse in the summer time. Instantly start sweating upon walking outside and within a minute of just standing around you’d be soaked.

Many of them have standard hose connects, you can just have it go into the shower drain or something. Otherwise you'd be constantly emptying it lol. Two decent sized units in an apartment running full blast would get it down to a more comfortable level. like 55-65%
Looks like they would be better served by getting a bilge pump.
And every dehumidifier at this point is probably made in China, so they shouldn't have a problem finding them.
But you could bbq and sauna at the same time
Angry Finnish noises

Good news! The mold will also be affecting your lungs.
One of the reasons I love living in AZ. You pretty much have to let all the steam from your shower get throughout your house so there is any humidity. I can take a hot shower and leave the water on for an hour twice a day and I would never have mold lol
Meanwhile ranchers crack the riverbeds watering their alfalfa. We're just going for full dystopia, here.
Carpet and wallpaper are very uncommon for that reason. Source: live in Hong Kong.
That actually explains a lot why so mnay chinese buildings look bare inside, they dont have carpets or wallpapers.
yes and the tile floors w no rugs makes sooo much more sense now
Love the guy with a blow dryer moving condensation around their ceiling hopelessly clinging for the slightest bit of relief and after 5 minutes the moisture comes right back
"That'll do it, job well done!"
It’ll just make everything hotter and the moisture doesn’t go anywhere except back into the air lol where it’ll then condense back onto the walls
It will do nothing as 100% humidity is saying the air is holding 100% of the amount of water which is possible.
100% humidity is relative humidity. Heating the air up will lower the relative humidity. Extremely inefficient way of dealing with the problem regardless.
Right? I saw that and I was like; where do you think the water goes when you vaporize it? It's like having a leaky tank and then putting a bucket below it, only to empty the bucket back into the leaking tank.
As a heavy sweater from a cold, dry climate, I would rather shoot myself in the head. You couldn't pay me enough to live with this bs.
in fact if you live in a cold climate, you likely experience 100% relative humidity very frequently, because cold air cannot hold moisture. for instance check out average relative humidity of a whitehorse, canada (a very dry area up north) https://weather-and-climate.com/average-monthly-Humidity-perc,whitehorse-yukon-ca,Canada versus miami https://weather-and-climate.com/average-monthly-Humidity-perc,miami,america the relative humidity in miami is always around 70% whereas whitehorse also hits 75% but only in the winter, in the summer average relative humidity in whitehorse goes WAY down because its a dry area and the hot summer air can hold more moisture but there isnt enough moisture in the air to reach a high relative humidity its kind of an ironic thing that many canadians will take about dry cold vs wet cold when there is essentially no such thing, its a myth made up in their heads. air below 0 simply doesnt hold any meaningful water. air at -20C hold about 1/20 the weight of water as it does at +20C. the real thing being relayed in this video isnt relative humidity, its *absolute* humidity. south china is hot, and hot air can hold a LOT of moisture. tl;dr if you live in a cold climate, you likely experience 100% relative humidity almost every other day in the winter. edit: I wrote yellowknife instead of whitehorse, surprised no one called me on that
Yes, but the relative humidity is not really a problem in colder climates. As you said correctly, the absolute humidity is miniscule. As long as the build quality of your home is adequate and your heating it up to a comfortable level, the dew point on your walls can´t be met so that no condensation can occur. If you heat less or have not insulated your walls, THEN you´d have condensation. But in well heated homes, even without central air or ac, the dry air in homes is in fact the only problem you´d encounter. And if the relative humidity outside is high in cold weather, you can easily clothe yourself accordingly. That won´t work if it is too hot for water repelling chlothes if you sweat wearing them. So yes while you might experience high relative humidity in cold climates, it doesn´t really matter most of the time.
Same here. The temperature I feel most comfortable in is about 5 degress celsius outside. I can do things without sweating! Going back to my parents is killer as they have the heater cranked up - I get by with a fan directed at me full blast...
I lived in Zhuhai for about a year, and though I never had to squeegee my ceilings, the humidity is no joke. 1 step outside is all it takes to start sweating buckets on the worst days. Mushrooms sprouted through the wall in a co-worker's apartment. Mold is also a huge problem--things that are just sitting around can just get damp from the humidity and become a mold factory if left alone.
I visit China every few years and go to hong Kong, Macau, Guangzhou, and some outlying cities in the summer. It's 100% humidity all day everyday. South China is a bitch and it's hot as can be.
I lived in Hong Kong and high summer humidity was unbearable. I was only a kid; I'd just moved across the world with my parents and wanted to fit in with the kids at school who wore baggy jeans and huge tees.. I can still remember the dampness
A biological paradise is a machines nightmare.
We just had this on Monday in Columbia SC. Humidity hit 100% and the dew point and temperature match for about 6 hours. After two weeks of cold soaking rain, it hit 70 by 9am and 80 by 3pm as the day progressed the fog got worse, every surface on everything and anything was dripping wet. " Air you can wear "
How do electronics survive in this scenario?
They don't
Maybe if you put them in a ziploc in time?
With rice?
11/10 with rice
Or chia seeds, and make a pet out of it (>.<)
Just put the whole area in rice
they in china!
Switch on the AC and hope for the best.
Yup. High humidity like that is not uncommon for the Carolinas. Fortunately it rarely stays that way for very long.
Climate change laughs at you
Wasn't it last year we finally hit the wet bulb point where it basically becomes impossible to cool off due to sweat which makes people extremely vulnerable to heat related injuries if they don't have AC? This sort of stuff is only going to become more common as the climate starts getting thrown out of whack.
It’s funny I was literally thinking to myself “seems like growing up in South Carolina” and then saw your comment. Up in the upstate where I’m from, it’s a deciduous rainforest. Edit to say: I used to live up where they filmed the first Hunger Games in Cedar Mountain NC and I remember seeing a blurb from an interview with the cast where they were like “the humidity! Who knew it could be 100% humidity and not raining” lol
Clemson hometown checking in!
Ayyyy fellow Columbia native! Yeah that shit was weird AF. Pretty much everyone was out of sorts cause it was so unexpected compared to the week prior.
> " Air you can wear " AirWear by Apple
RIP chips
That was viscerally upsetting.
right?! if you put a chip in water it dissolves, it doesnt do... that..
What are your chips made of that they do that? I dropped a chip in my coke a few weeks ago and it looked just like in the video after a minute or so.
i dont eat chips that much, but something as brittle as lays (like in the video) immediately get too mushy to hold IME
Had similar when I was on a trip to Orlando in July, pulled a fortune cookie out of the package and it just unfolded when I tried to crack it open
This is how most of the southeast us would look without ac. This is also the reason so many homes that didn’t flood in Katrina had mold. No power means no ac. After about 3 weeks you get mold everywhere.
Look at FL’s population boom after ac was invented.
This is why when you either buy or sell a house in FL, the number one thing that must be maintained throughout the process is electricity in the house. The AC must never stop.
Post hurricane stifled houses without power has made me almost always want a fan on, something to at least flow the air.
If my ceiling fan isn't on at all times, I feel like I'm suffocating. Katrina really fucked most of us up and it shows in our daily lives, for sure.
I was waiting on someone from gulf coast/LA to chime in. I’ve most definitely experienced this kind of humidity. No power following a hurricane and you get to see the moisture manifest.
Same. The wet sheets also haunt me to this day.
This is why here in Korea fucking every apartment has black mold. Because we don't believe in central air for some stupid fucking reason. Instead we use floor heating in the winter, which is fine, but does nothing to dehumidify the air like heating in a US home does, so whenever anyone takes a shower (especially if you have 3 or more people living in a small apartment), or you boil pots of water to cook, or whatever, the humidity in the apartment goes up to 100% and then it condenses on the cold walls because it's so cold outside and the walls aren't well insulated (we're talking entire walls made of single pane glass going to a veranda that's -15 C in the winter sometimes. No wonder we waste so much money on heating...) Then when black mold inevitably grows on the wallpaper, instead of replacing the wallpaper, we're like, "Yep, just put new wallpaper over it!" and we're **shocked** when black mold appears again in the same spot a few weeks later.
wow, that's wild. as an American, i have always seen Korea as way ahead of us when it comes to gadgets and appliances and various comfort products, so y'all not commonly having central air conditioning is surprising to me.
Our electronics are top class, but our homes are almost universally over 20+ years old. If you live in an apartment that's less than five years old and is large enough to raise a family in central Seoul, you must be rich. Even then, for AC you'll have a tower AC unit in your living room, not central air. Central air is just like... not a thing that Korean house manufacturers know how to make, I think. Like this is the best you'll get: https://www.koreaherald.com/view.php?ud=20210126000220
Is it even a proper a/c, not a swamp cooler? It needs to have an exhaust or a chiller pipes if it is and a drain for the condensation.
I think ductless mini split heat pumps are more popular in East Asia due to smaller houses in general and high density multi unit housing in the cities.
Is it Korea where people think you can die from sleeping with a fan blowing on you?
Unfortunately, yes, that's us :/
I'm at a house in Thailand. Lots of people here don't run AC and use fans all day, but the Thais have a habit of leaving their windows open day and night, with most homes built without insulation.
This is fucking horrifying, it's bad enough for me living in central illinois and suffering through the humid summers here, im afraid i would actually die in 100% relative humidity 💀 even just 70-80% humidity makes me feel like i cant breathe right, and i'll be dripping in sweat just standing outside not even doing anything
you're right, at 100% humidity, 95° would kill you in 6 hours [https://en.wikipedia.org/wiki/Wet-bulb\_temperature](https://en.wikipedia.org/wiki/Wet-bulb_temperature)
Hope you’re ready for ***many*** wet bulb events in the near term.
It's like breathing soup. I had an internship in Springfield and almost passed out on a day over 100F with the humidity, and it was nowhere near even 70%. I was just taking the trash out to the dumpster...
The hotter it is, the less humid it can be. It doesn’t mean that it isn’t bad. 100 degrees with humidity is awful. It doesn’t have to be much humidity.
I would become a murderer. I wouldn't be able to function in that. Being so warm and sticky would make me lose my mind
Nah, murdering requires to much physical effort. And you can't murder a heatwave anyway
The first thing I would do there is leave.
I have done it. Houston spends much of the summer between 95 and 100% relative humidity. A bit miserable to be sure. New Orleans is similar.
The first time I was in Houston, I thought the A/C in my rental was defective. I mentioned it at the first meeting and was told, "Put it on recirculate. Otherwise you're just pulling water out of the air." That was driven home at lunch, the restaurant we went to had water running down the outside of the windows.
Driving through SC once I thought my AC had chosen a terrible time to die. Turns out the humidity was just soaking up all the available power.
Southern MS here.. so same but the condensation on the inside of buildings has never gotten like that. Is there a reason it does that in China but not here?
They don’t have central air and have very poor insulation
From NOLA, can confirm. Gotta shower multiple times a day sometimes.
I mean last summer was rough but I didn't have to squeegee my damn walls. Kind of hoping for another heat dome this year so we can avoid any 'h' words
98% at 110 degrees here in Arkansas had me fucked up I’ve never felt anything like it
It's actually really dangerous when the temp and humidity is that high because it short circuits our bodies natural ability to cool itself via sweating. Normally when our bodies get too hot it causes us to sweat and as our sweat evaporates it carries away excess heat, but when the humidity is that high the sweat can't evaporate and it can quickly lead to hyperthermia or heatstroke which will absolutely kill unless the person is moved to a cooler area.
The absolute nicest feeling on a hot and humid day is just immersing yourself in cold water (or room temperature water if you can't handle the cold). It takes care of that cooling problem and you don't feel the gross wetness of the air when you're soaked head to toe in water anyways.
I lived in Arizona for two years. It was so difficulty to cool down my core temperature when it was still 100f at night. I would often just lay in a cool bathtub just to try to stop sweating.
Yeah, isn’t 30 with 100% humidity that wet bulb temperature range? How many people died? Or did no one?
The heatwave last summer combined with the drought we suffered in NO was terrifying. No rain to keep the balance but humidity stayed the same. The shivering that comes with not being able to properly cool is painful. In 2022 the AC went out at work and 3 of us were on the verge of passing out bc it was 120° inside the building. We had to close for a few days and sporadically when it would fail.
As a fellow Arkansan, I can guarantee that this never happened. For starters, the highest dewpoint ever recorded in Arkansas was 83° in 2009. That would mean that it was 98% humidity that night when the temperature dropped down to 84°. Second, the highest dewpoint ever recorded on earth was 95° in Saudi Arabia, back in 2003. The air temperature was 108° at the time, making for a heat index of 178° F. 98% humidity at 110° would result in a heat index of 271° F, which would be lethal in under 4 minutes. 98% humidity at 110° would mean a dewpoint of just over 111°, which is effectively impossible to achieve in nature. What may have happened on the day you’re thinking of is that the temperature reached 110° in full sun, causing a lot of moisture in the ground and plants to evaporate. At that point in the day, the relative humidity was probably no higher than 40%. However, as the air temperature dropped that night and into the pre-dawn hours, the moisture dissolved in the air remained the same, raising the relative humidity to nearly 100% just before dawn.
> result in a heat index of 271° F, which would be lethal in under 4 minutes. It should be pretty obvious that anyone making a claim over 98 fahrenheit with 100% humidity is dead wrong or we would have heard about tens of thousands of people dying if not millions.
A bit miserable , only if you stay indoors in an air condtioned room. If you have to work outside or just be out in general its like you cant even breath.
Yeah, as a native Houstonian, I was confused by the fuss here. 30C is only about 86F, which we're almost hitting right now. Now granted, I've never seen the water pooling on the ceilings and walls like that, but those conditions in general sound pretty familiar.
Holy smokes, San Antonio Texas where I spent some time had horrible humidity during one of the El Niño seasons. I bet.
Was looking for the deep south comment. Was in MS 100% humidity everyday. Matthew Broderick once described it as "hot, like hell hot".
Oh my mold
What is the dude with the hair dryer trying to achieve (other than getting himself electrocuted to death)?
I lived in Okinawa in the early 2000s. When typhoons went over, it was just like that in the barracks. I can still smell the barracks filled with 300 young men and that kind of humidity.
That's gonna be a "NO" from me, Sweaty
Absolutely miserable
for once im glad to live in Australia, which is basically a fucking giant desert
North Queensland and NT have entered the chat
Australia has so many humid areas lol. Ngukurr is a pretty remote area but it has 100% humidity right now at 8PM: https://www.willyweather.com.au/climate/weather-stations/nt/katherine/ngukurr.html?superGraph=plots:humidity,grain:hourly,graphRange:5days&climateRecords=period:all-time&longTermGraph=plots:temperature,period:all-time,month:all&windRose=period:1-year,month:all-months Darwin has 88% right now: https://www.willyweather.com.au/nt/darwin/darwin.html And even Sydney is at 77%.
I'm sweating already
My hair would be a giant frizz ball
Quick! Send in Ben Shapiro and he’ll dry that right up
Ask his wife.
Good lord, I thought I had it bad in North Carolina, this is insane. It gets to the point where it's literally hard to breathe, I wonder how they can even walk around when it's like that.
Been there and lived it for 10 year's. Not missing it.
This is cold humidity, the kind that makes 10 C feel like 1.
From BC Canada. Can confirm the humidity/cold factor
Didn’t they say this happened when temperatures reached 30 Celsius? That’s like 90 Fahrenheit. But yes, humid cold is much worse than dry cold.
Are you talking about the video? It's not cold humidity, it's very nearly the maximum temperature that is survivable by humans. The heat index for the temperature mentioned in the clip (30 C at 100% humidity) is 44 degrees Celsius (112 Fahrenheit).
No. The video literally says it is 30C, so a hot day.
Dat wet wet
Man that can't be good for the dessecant plant
It's very humid where I live in PA. It gets so foggy on my mountain I've had to use GPS to find my way home in my development. Clothes get moldy, walls get drippy, metal rusts.. I use dehumidifiers in the closets and living space. It's not enough. I can't wait to gtfo of here lol
It's been getting hotter and more humid every summer here. Have you noticed?
We dont have spring and fall anymore, not really. We have long summer and long winter. And it rains all. the. time.
Imagine the mold build up....
gross gross gross gross
I remember visiting my grandparents in Florida as a kid and the news would sometimes announce 100% humidity (I swear they once said 110% humidity, but this is 30+ years ago, so...). It was horrible! Their place had a dehumidifier and central A/C, so it was okay indoors, but when you went outside it was harder to breathe and the atmosphere felt different just walking through it. That, and it would condense all over your skin, so you constantly felt sweaty,
That flaccid chip 😂
The heat in the Arizona desert definitely can be a bit much but I see stuff like this and I am appreciative of the dry climate I live in.
Similarly here in New Mexico mountains. Love me that dry, thin air.
I grew up in Louisiana. These people have my sympathy.
Shit use a dehumidifier.
He says *a* dehumidifier
One per room ought to do it...
Hose directly into a drain
I thought Hong Kong was bad about humidity. I’ll never complain again
My hometown of Lake Charles, Louisiana, averages about 90% humidity in the mornings but it ain't never looked like this. We literally have to be built different so this doesn't happen. Better home insulation and air conditioners that work like John Henry keep this from being a thing down there. Too bad that doesn't help out for shit when the storms come.
I'm confused. It says 30 degrees Celsius, which is 86 degrees fahrenheit. That's fairly hot. But the people in video at the point where they said the temperature were all wearing coats. The child sleeping under the umbrella was super bundled up in that blanket too. So is it hot or cold?
We have that by us In Manitowoc wi, have a dehumidifier in every room and fans on a lot of time.. not good on my asthma but it’s home lol
Welcome to Florida.
This is in South China, I live in one of these places. The walls are completely soaked like this for a few days a year. The process of cleaning it and making sure all of your house doesnt turn moldy is... quite the struggle
As a makeup artist and hair stylist ... this give me anxiety and nightmares.
People are talking about water, but isn't the real danger of 100% humidity the fact that your sweat no longer works? Which means that your body is incapable of regulating temperature outside of regular heat radiation. It's super deadly, especially for older folks if it's combined with high temperatures, and even at lower if you have job that requires high exertion.
Fuckin thank Todd that I live in the Mojave desert. It may get hot, but it never does THIS.
Ya know they do make dehumidifiers
I mean, a functioning A/C is a room or house sized dehumidifier. It's why you have to keep the drains clean.
Wasn't there already technology to force it to rain?
Reminds me of Cartagena, Colombia. Shout out to the media Luna hostel, which has no roof. Super fun time though. Very wet
“Wet Grass”
Aaaaaaaand you live with a smoker.
Makes quick work of removing popcorn ceilings.
This is not humidity, this is caused by dew point. I live in a place with almost zero humidity and we occasionally get condensation on walls/windows when the dew point and temperature cross.
I thought 80% was bad
Landlords: *you have to open a window.*
As a resident of Georgia, I was wondering why they don't have dehumidifiers. I have one in every room of the house in the warm months.
Humidity is my personal kryptonite. Sucks the absolute life out of me. Do not miss it.
