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.

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 ...

(WHTM) — When temperatures rise, sometimes the air can feel dry and comfortable. But, sometimes it can feel downright tropical outside. This is caused by moisture in the air and it makes the air ...

Both terms are related to the amount of moisture in the air, but they have very different meanings. Air can hold only a certain maximum amount of water vapor at any given temperature. Dew point is ...

If you’re looking for a single number that’ll help you best determine whether or not it’s muggy outside, you’ll want to give this a read. On Tuesday afternoon, it was 71 degrees with a 56 degree ...

The heat index is a measure of how hot it really feels on your body when relative humidity is factored in with the actual air temperature. Since heat index values were devised for shady, light wind ...

I have always thought that at very low temperatures, say zero degrees or lower, the air would be dry. However, I have observed that the relative humidity is usually quite high when temperatures are ...

We all know that humidity can have an impact on our hair and skin, but a new study from researchers at Baylor College of Medicine and the University of Arizona suggests that relative humidity levels ...
