Heat Index Calculator
Calculate heat index and apparent temperature
Input: 90°F, 60% humidity
How It Works
Calculate the heat index (apparent temperature) from air temperature and relative humidity.
The heat index (apparent temperature) measures what the air temperature feels like to the human body when relative humidity is factored in. High humidity reduces the body's ability to cool itself through sweat evaporation. The NWS uses the heat index to issue heat advisories and warnings. Prolonged exposure to high heat index values can lead to heat exhaustion and heat stroke.
