Calculate Wind-Chill Temperature

Use our free online calculator to determine the 'feels like' temperature by combining the current air temperature with wind speed. Planning a ski tour or winter hike? Knowing the wind-chill helps you layer correctly and avoid hypothermia or frostbite.

How It Works

We implement the internationally recognised Canadian wind-chill formula:

Twc = 13.12 + 0.6215 Ta − 11.37 v0.16 + 0.3965 Ta v0.16

  • Ta is the ambient air temperature (°C).
  • v is the wind speed (km/h) measured at 10 m above ground.

Note: The equation is valid for air temperatures ≤ 10 °C and wind speeds ≥ 5 km/h.
