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.

Dew point and relative humidity, two terms that have floated around many weather forecasts over the years. What exactly do they mean and when are they best used to describe the conditions outside? Let ...

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 ...

Dew point is the temperature at which the air becomes “saturated” – in other words, it is holding all the water vapor it possibly can. If the temperature and the dew point equal each other, the water ...

Dew point, a direct measure of atmospheric moisture, is a much better indicator of discomfort than relative humidity. It is a conservative feature, meaning it remains reasonably constant during the ...

Here’s an even more deceiving weather situation. One day is 80 degrees and 50 percent relative humidity. Another day is 90 ...

Humidity levels are set to rise towards the end of the week, bringing with them a noticeable shift in the air’s moisture ...

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 ...
