Montreal is a great city to visit in September. With its European chic feel in Old Montreal it is irresistible during any month, but in September, many of the tourists have gone home, and the temperatures are comfortable in the 60s with very little humidity. Since crowds have thinned out, it is a good time to hit Montreal's top attractions. With fewer tourists in town, you will find better travel deals on airfares and hotel accommodations.

No longer hot and humid and not yet cold, many outdoor activities can still be enjoyed comfortably with just a little extra clothing on. Fall comes a bit earlier to Montreal than to Toronto, peak fall foliage season comes usually by the end of September.

Montreal Weather in September

The average temperature for the month is 60 F with an average high of 69 F and an average low of 48 F. You can expect about one-quarter of the month will have some rainy days—about 8 days out of 30 may experience some rain.

Over the course of the month, Montreal will experience a decrease of an hour and a half of daylight.

What to Pack

If you're going to Montreal in September, you should be prepared for a variety of temperatures. Pack clothing that can be layered. Pack your t-shirts, but just be sure to have a sweater and a jacket on hand. You can include shorts, but you might rely more heavily on trousers or long pants. You should include sweaters, a sweatshirt or hoodie, jacket, and closed-toe shoes. You may get some sunny days, and you may get some rain, so pack your umbrella, waterproof jacket, sunhat, sunglasses, and sunscreen.

September Events in Montreal

In September, you can expect to find many fall-themed fairs and festivals. Pumpkin festivals, foliage festivals, wine, and food markets crop up everywhere.

September Travel Tips

  • The first Monday of September is Labor Day. Banks and most stores will be closed. Expect crowds that weekend.
  • Canada has its own currency—the Canadian dollar—however in border towns and at major tourist attractions (like Niagara Falls) U.S. currency may be accepted; it is at the discretion of the proprietor. When in doubt, use a major credit card, which is widely accepted throughout the country.
  • If your trip spans from the end of August into September or is at the tail end of the month with part of your trip in October, there are plenty of activities in those months, too.
