Why are people using dew point instead of humidity?

humidity sucks rear end compared to dew point. I hate how humidity is the default measure that everyone knows which makes it impossible to get a cheap wireless outdoor thermometer that shows temperature and dew point instead of temperature and humidity or heat index.

The simplest hygrometers have historically been a piece of natural fiber that twists with humidity, attached to a needle. These react to relative humidity.

With electronic devices, it’s easy enough to calculate and display dew point, but they’re still stuck acting like analog instruments.

But humidity measures how humid it is. Dew point measures... the point at which dew occurs, I think? How is that good?

Babies should not have dew in the brain. If that's regularly occurring it means your baby is missing it's skull and should seek medical assistance immediately.

I simply just go outside and see how I feel. 'It's hot! It's muggy! The hills are on fire!' etc. No need for dew points or temperature nonsense.

Dew point just measures just how much water is in the air, while relative humidity measures both water and temperature of the air.

T of -20F and Td of -20F is RH 100%

T of 75F and Td of 75F is RH 100%

A Td of 75F is going to have ~50 times the amount of water vapor compared to -20F, despite them both having a relative humidity of 100%.

i know it's not a perfect indicator but like if it storms the higher the dew point is the worse it's going to be.

when we get storms with dew points in the high 60s or into the 70s it's bad poo poo and my power's going to be out

Dew point is the temperature the air needs to be cooled to in order to reach 100% relative humidity.

Commercial units kind of suck too. I got a weather station and the barometer is off by 3mbar or so, and the replacement they sent was even worse. I don’t even know if the hygro is accurate.

Is there one that even can calculate dew point outside of professional gear or sensor packages attached to a raspberry pi? Dew point is usually kinda buried in weather sites too.

dew point is the most metric rear end poo poo ive ever seen in my otherwise pure and good imperial system

"bbbbut but but its the true mass of water in the air" :cmon: nobody care about water gently caress water we freeze that poo poo in the middle of nowhere on the f temp scale.
the only standard i care about is if a 17th century king would get swamp rear end in similar conditions - as god intended

Weather zika babies with small wet brains not understanding dew points.

Dew point is the temperature where the air is 100% saturated with water, cannot hold any more at all.

As the air cools, the dew point also recedes and loses water holding capacity. You might see this effect when you put an ice cold glass of water out and condensation builds (from locally cooling air below the dew point) and your grandma starts yelling at you about not using a coaster, or more commonly, in the morning when everything is covered in "dew" from the air expelling the water it could not hold as the overnight temperature drops.

It's also important to recognize that your body cools by evaporating water off your skin into the air. If the air is at maximum water capacity, you aren't going to have much room to fit your cooling moisture in.

There are other fun things with dew points but these are good basics to start thinking about.
