Extreme Wind Chill at Cities in Canada: Annual Averages

Here you'll find information on how much severe wind chill major Canadian cities normally have in a year.

The tables below give the average number of days annually when the wind chill measures less than -20, -30 or -40.

Those wind chill measures equate to a temperature that feels like -20, -30 or -40 degrees Celsius (-4, -22, -40 degrees Farhenheit). The numbers are averages of weather data collected from 1981 to 2010.

When the weather is chilly outside, a bit of breeze makes a cool day seem even colder. That's when "wind chill" helps you estimate how cold the outdoor air really feels.

Wind chill is an index that Environment Canada uses to measure perceived temperature. The index combines temperature and wind speed to come up with a number that reflects how cold it actually feels on a person's exposed skin. Stronger winds produce a lower wind chill.
