About the Dew Point Calculator

- 01Enter your air temperature and relative humidity.
- 02Read the result instantly — it recalculates as you type.

Frequently asked questions
What does dew point tell me?
How muggy it feels. Above ~60°F (16°C) dew point feels sticky; above 70°F is oppressive. It's more intuitive than relative humidity.
Dew point vs humidity?
Relative humidity depends on temperature; dew point is an absolute measure of moisture, so it compares comfort across conditions better.
