Dew Point

Dew point is the temperature to which an air mass must be cooled (at constant pressure) for the relative humidity to reach 100 percent. At this point, the air is fully saturated and cannot hold any additional water vapor. If the air cools further, the excess water vapor condenses into liquid, appearing as fog, dew, or precipitation.

A higher dew point indicates a greater amount of moisture in the air. This not only influences the likelihood of condensation but also affects how humid and “comfortable” the air feels.
