Heat Index Calculator
Temp (°F)
Humidity (%)
The heat index (apparent temperature or "feels like") combines air temperature and relative humidity to indicate how hot it actually feels to the human body. High humidity prevents sweat from evaporating, reducing the body's cooling ability.
💡
Pro Tip
Stay hydrated, seek shade, and avoid strenuous activity when the heat index exceeds 103°F (39°C).
