Feels-like temperature

Enter temperature, humidity and wind: get the feels-like temperature with the official formulas, and the risk level in extreme conditions.

Temperature (°C)

Relative humidity (%)

Wind (km/h)

How it works

In the heat, humidity hinders sweat evaporation and makes it feel hotter than it is: that's the heat index (used by NOAA and civil protection agencies). In the cold, wind strips heat from your skin: that's wind chill. The tool automatically picks the right formula for the conditions.

Examples

32 °C (90 °F) with 70% humidity feels like about 41 °C (106 °F). And −5 °C with a 30 km/h wind «bites» like −13 °C.

Note

The formulas apply in the shade: in direct sun it can feel even hotter. On extreme days, follow your health authorities' guidance.
