This calculator determines dew point from given temperature and relative humidity of air. Dewpoint If the air is gradually cooled while maintaining the moisture content constant, the relative humidity will rise until it reaches 100%. In summer, the higher the relative humidity, the higher the apparent temperature. The calculated data is based on the assumption from standard conditions that the air temperature drops 9.84 degrees C per 1000 m of altitude and the dewpoint drops 1.82 degrees C per 1000 meters altitude.
