What is the dew point?

Dew point

Starting to feel a little humid.

The dew point is the temperature at which the air becomes fully saturated and moisture starts to condense. A higher dew point means the air holds more moisture and feels more humid.

About the dew point

The dew point is the temperature the air would need to cool to before it becomes fully saturated with moisture. Unlike relative humidity, which shifts as the temperature changes, the dew point is a steady measure of how much moisture is actually in the air. That makes it a handy guide to how humid and sticky a day or a room really feels.

Pair it with the heat index calculator to see how hot it feels, the room comfort checklist, and the room comfort and temperature awareness guide.
