Weather in Montreal

Best time to visit

The best time to visit Montreal is the summer, when the nights can be sultry and the whole city seems to be partying (notably during Festival International de Jazz de Montréal). Temperatures average 22°C (72°F) but can exceed 30°C (86°F). Conversely, cold fronts bring crisp, windy weather in the early and later parts of summer. Cooler autumns are a great time to visit the forested Laurentians or hills of the eastern townships. Even the cold and snowy winters are enjoyable - the city authorities maintain more than 150 skating rinks in the region as daily averages drop to -10°C (14°F).
