Montreal is a great city to visit in September as you can stroll the quaint streets of Old Montreal enjoying the European chic feel and have smaller crowds of visitors to deal with. Temperatures are comfortable and there is very little humidity. Fall comes a bit earlier to Montreal than to Toronto, for example, and fall foliage season peaks around the end of September.

Since crowds have thinned out, it is a good time to hit Montreal's top attractions such as Mount Royal Park and the Arboretum. And this is shoulder season so you will find better travel deals on airfares and hotel accommodations.

Montreal Weather in September

The average temperature for the month is 60 degrees Fahrenheit (16 degrees Celsius), and you can expect that about one-quarter of the month will have some rainy days—about eight days out of 30 may experience some rain.

  • Average high: 69 degrees Fahrenheit (21 degrees Celsius)
  • Average low: 48 degrees Fahrenheit (9 degrees Celsius)

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, including your T-shirts, but just be sure to have a sweater and a jacket on hand, too.

You can include shorts, but you might rely more heavily on trousers, jeans, or long pants. You should include a sweatshirt or hoodie 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.

Walking shoes are ideal for September as the weather is mild and you'll enjoy being outside. Save your dress shoes for the evening and be comfortable while sight-seeing or taking in an event where you'll be on your feet most of the day.

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 major credit cards, which are widely accepted throughout the country.
