Where it gets cool is when the air is absolutely saturated (that is, _at_ 100% humidity), and then the temperature _drops._ All the excess moisture becomes visible in a phenomenon we know as "fog."

As a Floridian, I knew most of this stuff since I was young & watching the local weather, however this was a great way to describe everything. Great informative video.

This explains why we in Arizona are quick to say it's "A dry heat" Because yes it's 112 outside but the dew point is like 20 so your sweat evaporates instantly, making you feel cooler than it actually is. The sweat is actually doing it's job and why evaporative coolers work so well in the dry times. Where it really sucks is when it's 103 and the dew point is 85. You feel like your breathing in soup while covered in a slick layer of sweat and just beads up and drips off you rather than evaporating. thankfully that only happens during the monsoon. and it's been 20 years since Arizona had a "real" monsoon.

At first, I thought the title of this video was 'Why Does Humanity Feel Gross?'

A very clear presentation. Thank you!

yeah i had trouble with this! it clears it up mostly

Great explanation of a topic most people are uninformed about. Do weather stations still use Dry Bulb / Wet Bulb thermometers to read the dew point?

Dew point of 70 is really funny

Thanks

Very informative video

I always enjoy your videos! Could you do one about what happens, chemically, to foods when they get freezer burned, and why it makes them taste bad? :)

4:25 what? below dew-points 60 regardless of the temperature, shows a temperature !?

Awesome

hmm,i got some sense,but how rain alter the temperature and we feel good during rain but sometime after rain with no wind it feel so muggy

please repost this vid in may/june. Now-a-days, i'm worried about lake-effect snow, time to frost bite, and defrosting salts....

So where is the best place to live in the United States (dew point wise)?

Very useful 🥰🥰

Finally a video that actually explains!

I am living in a city where june avg temp is 48 and July - sep avg temp is 37 with high humidity so(Sargodha Pakistan) i am always sweating in that 3 months and inly AC gives me peace then.♨️

If that was a real heat index example then they be lying down here in Texas lol.

1:50 how sweat and humidity relate, water molecules absorb heat off skin and evaporate into the air, but can't if air is fully saturated so it stays stuck on you. 3:05 'how it feels' is subjective, but dewpoint is objective, it's the temp the air must cool to to reach 100% saturation.

today our weather humidity is 96%. it is good?????

I absolutely don't get it

👍👍👍👍much useful content..👍👍👍

Trivia quiz which state is more humid Tennessee or Michigan

I do not see a 70 dew point on the dewpoint

Does anyone know a good app with all this extra info?

Humidity does not feel gross. What are you talking about?

MAKES POT SMOKING A BREEZE ,

and here I am in san diego kackling at those suffering in the north east

"We can't all be so blessed as to live in San Diego." True, and thank God.

What to wear?? Definitely NOT THAT!!!

Celsius, the superior temperature system that makes sense.

Her voice has more cracks than an old teapot 🤓

THANK YOU! I had this doubt for so many years, I thought it would never be cleared up. See, my hometown is muggy and hot for most of the year. Summers are hell, like stepping into a sauna, I sweat profusely all day and night if I'm not in an air conditioned room. It's almost sea level but right in the middle of the continent, so no sea breeze... little to no wind, which make things worse. It's one of those situations where your skin sticks to the sheets making a mess and you can't have a comfortable night of sleep during summer... unless, like I said, you have AC. 5 years ago I moved to a city in the same state, but on the opposite side, that is almost 2km above sea level, it's way colder all year round, and there's only like a week at most where it gets really hot, and I could sweat during the day... most nights gets colder, so I got rid of the dictatorship of the air conditioner altogether. xD It is a freedom I didn't experience during summers outside vacation trips and whatnot. Not having to be stuck inside a room with AC when I didn't want to sweat profusely and get all smelly. :P But even so, it is known through weather and statistics that my current city is supposedly far more humid. Yet, this never connected for me. How can it be? My experience is almost the opposite. I was always sweatting buckets in my hometown while here I almost never break a sweat, despite that humidity percentage being higher on average here. So this video makes perfect sense... it's overall relatively more humid, but not actually in a proportional sense. I could never find a proper answer for this. You guys finally finally solved it. Now perhaps I'll also find my answer of a city in Japan that has a weather similar to where I currently live... another lifelong question I still didn't get an answer to. Dreams of moving there on day, kinda hard to happen, but you know.

So basically if it's humid it feels hotter

I love humidity lol

100% humidity how come we don't drown?

please use SI units

This explained nothing.

Humidity such a sticky mess Your shirt sticks like glue

Disgusting.

😡 Oh dear! Why must a scientific organisation persist with Fahrenheit? Stop pandering to the lazy or poorly educated and take a stand on this in favour of Celsius. How difficult could that be? Really!

The usage of farenheit confused me. They should have shown the conversion constantly.

She looks like she is lecturing me on my white privilege this whole video.
