What is a 'dew point'?
Open in App
Solution
In simple terms, the dew point is the temperature at which a given concentration of water vapor
in air will form dew. More
specifically it is a measure of atmospheric moisture. It is the temperature to
which air must be cooled at constant pressure and water content to reach
saturation. A higher dew
point indicates more moisture in the air; a dew point greater than 20 °C
(68 °F) is considered uncomfortable and greater than 22 °C
(72 °F) is considered to be extremely humid.Frost pointis the dew point when temperatures are below freezing.
