The Climate and Weather of Windsor, Ontario

Average Daily Maximum Temperature – Minimum – Sunshine – Raindays – Snowdays – Snowdepth – Windspeed

Located in the far south of Ontario, close to the American city of Detroit, Windsor enjoys the warmest climate of any of Ontario’s cities.


Windsor has a semi-continental climate, with a warm, humid summer and a cold winter.

Windsor’s climate is modified by its location on the shores of the Great Lakes. The water in the lakes ensures Windsor is warmer in winter and cooler in summer than it would otherwise be. The lakes are also the source of Windsor’s summer humidity, which many people find uncomfortable.

Although Windsor is Ontario’s warmest city, winters are still severe.

Snow depths of greater than 1 cm are seen on about 53 days each year in Windsor compared with about 10 days each year in Vancouver, 35 days in Penticton, 65 days in Toronto, 88 days in Calgary, 120 days in Ottawa, and 132 days in Winnipeg.

Many factories and industrial plants in both Canada and the USA are located on the Great Lakes and smog has become something of a problem in Southern Ontario.

Windsor enjoys a sunny climate. Its summers usually have a generous number of warm or hot sunny days. Winters are rather less sunny than in the prairie cities of Calgary and Winnipeg.

Windsor’s day-to-day weather can be changeable throughout the year.
