What is the dew point?
WeatherAtmosphere
Quick Answer
The dew point is the temperature at which air becomes saturated with water vapour and condensation begins. When air cools to its dew point, dew, fog, or clouds can form.
The Full Story
The dew point is one of the most useful ways to describe atmospheric moisture because it directly reflects how much water vapour is in the air. A higher dew point means the air is more humid; a lower dew point means it is drier. When air cools to this temperature, water vapour condenses into liquid droplets on surfaces or in the air. Meteorologists use dew point to forecast fog, frost, and how muggy a day will feel.
Key Facts
1.Dew point is measured in degrees Celsius or Fahrenheit
2.Fog can form when air reaches its dew point near the ground
3.High dew points often make summer weather feel oppressive
