Climate in Canada varies widely from region to region. In many parts of the country, particularly in the interior and Prairie provinces, winters are long, very cold, and feature frequent snow. Most of Canada has a
continental climate
Continental climates often have a significant annual variation in temperature (warm to hot summers and cold winters). They tend to occur in central and eastern parts of the three northern-tier continents (North America, Europe, and Asia), typi ...

Wind chill (popularly wind chill factor) is the sensation of cold produced by the wind for a given ambient air temperature on exposed skin as the air motion accelerates the rate of heat transfer from the body to the surrounding atmosphere. Its va ...
s. In non-coastal regions, snow can cover the ground for almost six months of the year, while in parts of the north snow can persist year-round. Coastal British Columbia has a more temperate climate, with a mild and rainy, cloudy winter. The British Columbia Southern interior has a semi-desert climate in many locations, with long warm to hot, dry summers, and short moderate winters. The immediate area adjacent to the town of Ashcroft, features Canada's only true desert. On the east and west coasts, average summer high temperatures are generally in the low 20s °C, while between the coasts, the average summer high temperature ranges from , with temperatures in some interior locations occasionally exceeding .

The rate of warming has been higher across the North and in the Prairies.
