Most people understand relative humidity, but the dew point is a much better measure of how humid it really feels.

We’ll be discussing the difference between dew point and relative humidity in this edition of Weather Tidbits. Both of these weather parameters describe moisture in the air, but represent very ...

Another example would be in the winter. If the air temperature were 45 degrees and the dewpoint were 40 degrees, you're dealing with 85% relative humidity. That sounds really steamy!

Without explaining the equation variable by variable, we can simply state that the relative humidity is determined by how close the air temperature is to the dew point temperature.

Referring to the dew point to describe how the air feels or how much moisture is present is more appropriate because relative humidity fluctuates rapidly from temperature changes. The relative ...

The dew point typically changes much more slowly compared to relative humidity, unless a front is passing through or precipitation starts to fall in a dry air mass. Higher dew point temperatures ...

Now consider the dew point: Let’s say both samples are in same-sized buckets and have a dew point of 32 F (0 C). That’s a relative humidity of 73 percent for the cooler sample and 23 percent ...

Dew point, however, gives a better reading on how much moisture is in the air. Think of relative humidity as describing how much water is in a glass, and the glass is the air temperature.

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.

If it is 100 degrees and the dew point is 72 degrees, relative humidity would be 40 percent. So we meteorologists prefer the consistent message that comes with dew point.

Look at today. In the morning we had a temperature of 74 degrees, a dew point of 70, and a “Relative” humidity of 87%.

If the dew point was also 32F, there would be 3.8 grams of water in the air. On that particular day the relative humidity would be 100%, but you certainly wouldn’t notice it beyond scraping the ...
