With Summer in Full Swing, Montreal in August Heats up With Festivals & Events

Summer is the most popular time to visit the unique city of Montreal. Infused with French heritage, including a large French speaking population, Montreal draws huge numbers of Canadians, Americans and global visitors for its well-preserved Old Town, sophisticated cultural, culinary scene and overall funky European vibe.

 

Montreal is a city best explored on foot, and summertime allows visitors to do so with greater ease than in winter when snow is abundant and sidewalks can be difficult to navigate. 

Despite the heat and humidity of August, there's so much to do and no shortage of watering holes to stop into and cool off.

Weather

Expect hot and humid weather. It is not a dry heat and perspiration will be an ongoing reality while in Montreal in August. That said, air conditioning on trains, in hotels, shops, and restaurants can be refreshing but turn equally uncomfortable. Having a light sweater on hand is always a good idea. 

  • Average August temperature: 21°C / 68°F
  • August average high: 28°C / 83°F
  • August average low: 16°C / 60°F

Visitors can expect rain about 9 days out of 31 in August.

What to Pack

  • Shorts; t-shirts; light-coloured, long sleeve shirts; light, long pants; sandals; closed-toe shoes.
  • Umbrella
  • Bug spray if you're heading out of the city.
  • Sunhat, sunglasses, sunscreen
  • Light jacket, hoodie or shawl.

Perks

  • Montreal is truly a city of festivals in the summertime. This city knows how to celebrate the season and does it often.
  • Summertime is patio season - a nice way to wile away the day or evening.
  • Mont-Royal is a delight any time of year, but in summer, visiting this urban park is a must. Go on a Sunday to enjoy the weekly drum fest known as Tam Tams. 

    What's Not So Great about Montreal in August

    • Temperatures in the 80s and 90s and high humidity may be a turnoff to some.
    • Summer means higher travel prices, fuller than usual hotels and restaurants and possibly longer lineups at Montreal's tourist attractions. Be sure to book transportation, including flights, trains, rental cars and hotel transfers, restaurant reservations, city tours, and hotels ahead of time.

    Good to Know about Montreal in August

    • Montreal temperatures can get into the 90s and it is humid. Be sure to keep water bottles with you, especially important for older travellers and children.
    • Unlike most other Canadian provinces, Quebec does not have a long weekend at the beginning of August
