Humidity is the concentration of water vapor in the air.
The concentration can be expressed as absolute humidity, specific humidity, or relative humidity.
Relative humidity is the most frequently encountered measurement of humidity because it is regularly used in weather forecasts.
It’s an important part of weather reports because it indicates the likelihood of precipitation, dew, or fog.
Higher relative humidity also makes it feel hotter outside in the summer because it reduces the effectiveness of sweating to cool the body by preventing the evaporation of perspiration from the skin.
This effect is calculated in a heat index table.
