What it's like in September
Is September the right month?
The best month in Montreal is July (8.3/10), 0.5 pt higher than September.
Our verdict
Montreal is the 2nd largest French-speaking city in the world after Paris: island at the confluence of the Saint Lawrence, mix of French/English/multicultural. July is my favourite month (8.7/10): 18-27°C, 39% rain, festivals (Montreal International Jazz Festival early July, Just for Laughs mid-July, Osheaga music early August), terraces everywhere.
Plan your trip
Hotels at their lowest outside peak season, highest on comfortable months. Shoulder seasons offer a good price/climate compromise.
