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 ...

Summer is here, and heat and humidity have arrived.

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 ...

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?

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 ...
