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 ...

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 ...

When referring to the mugginess of the air, meteorologists will point to dew point rather than relative humidity. Relative humidity is indeed a measure of how much moisture is in the air relative to ...

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 ...

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 ...

Going on a run and curious about how muggy it's going to be out? Maddie Sofia chats with producer Thomas Lu about relative humidity and why some meteorologists are telling us to pay more attention to ...

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 ...

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 ...

I took a phone call the other day asking why I don’t use the “Relative” Humidity number on my weathercasts like others, but use the Dew Point, instead. Then I wondered if the person on the other end ...

I've long wondered whether dew point or relative humidity is more important for good seeing. Which would be better: a cool night with lower dew point but higher humidity, or a warm night with higher ...

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 ...
