Constant Dew Point

Dew point is a measure of absolute humidity, the mass of water vapor per unit volume of air in the atmosphere. Dew point is independent of ambient temperature, at constant pressure. If the temperature rises, the dew point will remain constant but the relative humidity will drop. And conversely, if the temperature falls, RH will rise as seen in the dashboard chart below:
