Montreal Climate & Weather

With predominantly wet, warm summers and cold, snowy winters, the humid continental climate of Montreal is varied and seasonal. In winter (December to February), snowfall is abundant and common both in spring and autumn. Temperatures well below freezing are experienced in winter, with average low temperatures dropping to 7°F (-14°C) in January, and the bitter weather exacerbated by wind chill.

Summer (June to August) brings sunshine and pleasant days, with high humidity on occasion, although highs seldom exceed 86°F (30°C). Rain can be expected any time of year in Montreal, but summer tends to be the wettest season. A feature of the climate of Montreal is the possibility of late autumn heatwaves, enjoyed as 'Indian summers', which frequently occur.
