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 ...

This week, there has been lots of discussion regarding the dew point and how it relates to humidity. While most of us have probably heard of the dew point, do you actually know what it is?

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 ...

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 ...

Dew point/relative humidity questions come up fairly often and this is a good one. Water vapor in the atmosphere is pretty important for deep-sky observing and photography. The atmosphere can only ...

The short answer is both terms are different and describe different things about moisture in the air. The dew point is another temperature value. It is the temperature air needs to cool to become ...

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?

Humidity can make or break a summer day. A sunny day with a temperature of 85 degrees can feel pleasant when the humidity stays low, but once the humidity cranks up, that same day can become ...
