Summer is the most popular time to visit Montreal. Infused with French heritage, including a largely French-speaking population, Montreal draws huge numbers of Canadians, people from the United States, and international visitors for its well-preserved Old Town, sophisticated cultural sites, and culinary scene. In August, the city comes alive with events like the Montreal World Film Festival and the Osheaga music festival.

High temperatures make it nice to walk around and sightsee, but the extreme humidity may be a turnoff to some. It can also get chilly at night thanks to the city's location along the St. Lawrence River. Summer also means more crowds and higher travel prices, fuller than usual hotels, and longer lines at Montreal's top tourist attractions.

Montreal Weather in August

Montreal has hot and humid weather in August, with the average high hitting 75 degrees Fahrenheit and the average low dropping to 54 degrees Fahrenheit. On extreme days, temperatures can reach in the 90s. If you plan on walking around a lot outside, expect to be very sweaty. That said, air conditioning on trains, in hotels, shops, and restaurants can be refreshing. Visitors should also expect rain for about nine days in August.

What to Pack

Because of the humidity and heat during the day, most of the clothes you'll need should be airy, and lightweight, including shorts, T-shirts, and sundresses for women. Although sandals are perfectly acceptable, you may want closed-toe shoes for walking around Montreal's cobblestoned Old Town. Also, don't forget the sunscreen, hats, and sunglasses for bright, sunny days. In the evening, bring a light jacket, shawl, or sweater as it can get a bit chilly. If there's rain in the forecast, pack an umbrella, and for those heading out of the city into the more rural areas, you may want to have a bug repellent on hand.
