Estimate dew point temperature using air temperature and relative humidity. This calculator shows dew point in Fahrenheit and Celsius, plus a simple comfort guide for dry, comfortable, humid, and muggy conditions.
Air temperature:
Enter the current air temperature.
Relative humidity:
Enter the humidity percentage. Higher humidity usually raises the dew point.
Temperature unit:
You can enter temperature in Fahrenheit or Celsius. The calculator converts as needed.
Dew point result:
The result estimates the temperature where the air would become saturated with moisture.
A dew point calculator is useful for weather planning, humidity comfort, gardening, HVAC checks, indoor moisture control, fog potential, condensation risk, and outdoor activity planning.
Dew point is often a better comfort indicator than relative humidity because it directly relates to how much moisture is in the air.
Your dew point result estimates the temperature at which air would be saturated with water vapor. A low dew point usually feels dry or comfortable, while a high dew point can feel humid, sticky, or muggy.
Dew point is the temperature where air becomes saturated with moisture and water vapor can begin to condense.
No. Relative humidity is a percentage, while dew point is a temperature that shows how much moisture is in the air.
Many people start to notice humidity when the dew point is around 60°F or higher. Dew points around 70°F and above often feel muggy.
No. Dew point is normally equal to or lower than the air temperature.
