Montreal is a great city to visit in September because you can stroll the European-like streets of Old Montreal and also have smaller crowds of visitors to deal with. Temperatures are comfortable and there is very little humidity. Fall arrives a little bit earlier in Montreal than in Toronto, so you'll also have better chances of catching the beginnings of the fall foliage season, which typically starts around the end of September.

Since crowds have thinned out, it's also a good time to hit up Montreal's top attractions such as Mount Royal Park and the Arboretum. Plus, it's the start of the shoulder season, so you will typically find better travel deals on airfare and hotels.

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—approximately eight days out of 30 experience some rain.

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

The days are getting shorter, but you can still count on between 12 and 13 hours of daylight with sunset always occurring after 6 p.m.

What to Pack

If you're going to Montreal in September, be prepared to encounter a wide range of temperatures. You should pack clothing that can be easily layered and try to carry a light jacket around with you in case the temperature drops. You might want to pack your shorts, but you'll probably get more use out of a pair of long pants. Definitely bring 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. Comfortable walking shoes would also be ideal for a September trip, as the weather is mild and you'll want to spend time outside.

September Events in Montreal

In September, you can expect to find many fall-themed fairs and festivals. Pumpkin festivals, fall foliage festivals, wine, and food markets usually crop up everywhere. Many events may be canceled, postponed, or altered during 2020, so be sure to check the organizer's website for the latest details.

  • Leaf Peeping: At the end of the month, you can enjoy the colors of the fall foliage in some of the city's parks, such as the Mount Royal Park, the Montreal Botanical Garden, or the Morgan Arboretum.
  • The Gardens of Light: Hundreds of handmade silk lanterns from China combine to create an Asian-inspired ambiance at the Montreal Botanic Garden during September and October. This annual event coincides with the Chinese ​Moon Festival, a harvest celebration also observed in Taiwan, Vietnam, Singapore, Malaysia, and other Asian nations.
  • Le Burger Week: Every year during the first week of September, restaurants from major cities across Canada, including Montreal restaurants, make special burgers just for Le Burger Week. Burger-lovers all over Canada will have the chance to discover these delicious creations and vote for their favorite ones while the chefs can experiment and present their newest creations.
  • POP Montréal International Music Festival: This annual not-for-profit event from September 23 through 27, 2020, presents emerging and established performers from around the world. It's a great festival for seeing some of the newest up-and-coming artists in the industry.
  • Yul Eat Food Festival: If the festival is on during your visit to Montreal, head to the Quartier des Spectacles neighborhood for culinary discovery and decadence with grand tastings, dinners featuring wine and food pairings, exhibitions, and classes. This event is canceled in 2020.
  • Montreal Canadiens: If you like hockey, you can try to score tickets for some pre-season games held at the Centre Bell.

September Travel Tips

  • Like the U.S. Canada celebrates Labor Day on the first Monday of September. Expect weekend crowds and bear in mind that banks and stores may be closed for the holiday.
  • While Canada has its own currency, the Canadian dollar, U.S. dollars are accepted in some places around Montreal, but you will not get a favorable exchange rate; it is at the discretion of the proprietor. When in doubt, use major credit cards, which are widely accepted throughout the country.
