When is the best time to visit Montreal?

The best time to visit Montreal is between May and October, the most comfortable stretch of the year on these averages.

Montreal has a real winter and a real summer. Snow is part of the cold months, not a freak event. The outdoor year is short in the middle and long at the ends of summer. Montreal is a city in Canada. This page is about Montreal, not a country average.

Most visitors come once the freeze has lifted, or they come on purpose for the cold. Do not book Montreal as a sunlounger destination. The monthly table owns the averages. This layer is the year those numbers sit inside.
