Relative humidity is expressed as a percentage, whereas the dew point is expressed in degrees.

Summer is here, and heat and humidity have arrived.

NORFOLK, Va. — Most summer days, you hear us talk about “humidity” when describing how the air feels. While many people are familiar with the term relative humidity — the percentage of water vapor in ...

Relative humidity and dew point are often mistaken for the same thing and can be sources of confusion. But what are the differences between the two, and which is more relevant in everyday life? >> ...

Every summer, I get asked this question: "Why don't you use relative humidity? I don't care about the dew point." The thing is - you should care about the dew point more. The dew point is quite ...

The dew point is the temperature that the air would have to be cooled to (at constant pressure) in order to reach saturation. As the temperature drops to the dew point, water vapor molecules condense.

Meteorologists talk plenty about the dew point temperature during the summer, as it is a great indicator of humidity and a condition to watch when severe weather is possible. So what is it? The dew ...

There are multiple ways to describe how wet the air is (yes, pretty much all air is wet). What I mean by that is there are water molecules tucked in between the gases like nitrogen and oxygen that ...

GREENSBORO, N.C. — Two common weather terms you'll hear many times in the warmer part of the year are "dew point" and "relative humidity". While both relate to moisture in the air and the "stickiness" ...

That is because the dew point is a measure of how much water vapor is in the air and relative humidity is a measure of how much water vapor is in the air relative to how much water vapor could be in ...

Relative humidity and dew point are often mistaken for the same thing, and can be sources of confusion. We have recently gotten questions about the differences between the two, and which is more ...
