– Calculates the New Wind-Chill Index (in °C), from air temperature (°C) and wind-speed (knots).
– Real-time results as you slide the bars for the temperature and wind-speed values, so you can see the effect on wind-chill if the conditions change.
– Designed for anyone venturing out into cold and windy conditions, eg. hikers, sailors and tourists.

What’s Wind-Chill?

When it’s windy, our skin gets colder than it would if the air wasn’t moving. This is the Wind-Chill Effect. It affects people and animals because they have circulating blood. It doesn’t affect inanimate objects, such as an alcohol thermometer. The screenshot shows a real example of this cooling effect.

About the Calculation

WindChillMetric uses the New Wind-Chill Index: the international standard for calculating wind-chill. The New Wind-Chill Index is only accurate in the range of conditions where wind-speeds and temperatures that can combine to be unexpectedly hazardous to human health. These are wind-speeds above 2.6 knots (a brisk walk), and temperatures below 10ºC. Higher temperatures won’t freeze you no matter how strong the wind, and lower wind-speeds scarcely change the apparent temperature.

Disclaimer: Results are indicative only. You’ll probably feel the cold more if you’re soggy, unhealthy, young, old or tired. We can take no responsibility for the accuracy of this information or how you use it. Be careful out there.
