Weather in Montreal

Montreal has a semi-continental climate, with warm, humid summers and blistering cold winters. The harsh Canadian winters will likely be your biggest shock when moving to Montreal. 

Temperatures can drop as low as -4°F (-20°C), but with wind chill, it can feel considerably colder, increasing the risk of frostbite. The coldest month is January, with average temperatures around 14°F (-10°C). During winter, you will see a lot of snow, along with occasional rain and sleet. Staying active and layering up will help you acclimate more easily.

The suburbs tend to be a couple of degrees colder than the city centre during winter, partly due to the heat island effect in urban areas. Be cautious of icy roads and sidewalks, particularly in areas with limited street lighting, as suburban snow and ice removal can be less frequent.

Montreal's summers are warm and rainy, with high humidity levels often exceeding 80 percent. In July, temperatures usually average around 77°F (25°C), and you can expect plenty of sunshine. The humidity can make it feel warmer, so staying hydrated and taking breaks in shaded areas is recommended. Parks and spots near water bodies tend to be a bit cooler, offering some relief from the heat.
