Montreal - Weather


Canada converted to the metric system in the mid 70’s. Depending where you come from, to understand our weather temperature, please go to this website.

Our temperatures are in Celsius, however, our neighbours to the south, the United States of America, are on the imperial system, so their temperatures are in Fahrenheit.

Summers are usually hot and humid. Daily temperatures can range from warm (24C = 74F), to hot (30C = 86F), to a very uncomfortable (40C = 104F), which includes humidex, a combination of heat and humidity.

Cool fronts can bring crisp, less humid and windy weather in the early and later parts of summer.

Winter usually brings cold, snowy, windy, and at times, icy weather, with a daily average temperature ranging from –9 to –10C (16 – 14F).

Snow usually arrives at the end of November, and lasts until the end of March. The average yearly snowfall is 225 cm = 89 inches.

January and February are the coldest months with average temperatures of between –13C to – 23C (10F to –10F), not including the wind chill which can make the temperature drop to a very cold –33C = -27F.

Spring and fall are pleasantly mild and sunny most of the time. April and May can bring showers and even thundershowers.
