Ohio and Kentucky were among 18 states that experienced record-breaking humidity in July. Here's why it has been so humid this summer.

MIKE MOSS SAYS: Myra, There are different ways to represent humidity, such as absolute humidity, specific humidity, relative humidity, and using the dew point as an indicator of absolute humidity ...

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.

The relative humidity depends on the air temperature, even when the dew point stays constant. In the example above, we have a dew point temperature that stays constant at 65 degrees.

So, what is the difference, if there really is one? To find out, let’s dive into what dewpoint is and what relative humidity is. Dewpoint is a more direct measure of moisture in the air.

What is the difference between the dew point and relative humidity and which is a better metric to represent humidity?

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

We know proper indoor ventilation is key to reducing the spread of Covid-19. Now, a study by MIT researchers finds that indoor relative humidity may also influence transmission of the virus.

It includes absolute humidity and relative humidity. Absolute humidity measures the actual amount of water vapor in the air, regardless of the air's temperature, according to the Weather Service.
