you know how a can of coke will sweat when you take it out of the fridge? Dew Point is the temperature that anything below that will do that at

when it's humid, the dew point "goes up" because the air can't hold as much moisture. That's the chemistry of it but it's a measure of how "comfortable" things are, and how good the air is at absorbing heat from you.

So a dew point below the current temp is good? Normally I just look at the humidity. And in the south, it's always humid. -- nm - sycor Aug 17, 08:02 4
- It can't go above the actual temp (outside of some rare and weird conditions). when Dew Point = temp that means 100% humidity. -- nm - Reagen Aug 17, 08:10 2
  - but does a Dew Point of 0% mean that if you pour out a stream of water, it instantly vaporizes into the air? - tRuMaN the science guy Aug 17, 08:22 1
    - dew point would be a temperature. at a theoretical relative humidity of 0%, yes, it would all evaporate almost instantly. -- nm - Reagen Aug 17, 08:26
- Dew point is always below the current temperature unless it’s raining. - spamlet Aug 17, 08:06
