Montreal changes a lot through the year. Winters are long and cold, summers are warm and packed with festivals, and spring and fall pass quickly. Here’s what to expect each month. For actual temperatures, look at the Government of Canada’s climate data, and check festival dates on each event’s official site, because they change every year.
January and February
The coldest months, with snow on the ground most of the time. It’s the season for Igloofest at the Old Port (see events and the festivals guide), Montréal en Lumière and skating when the rinks are open. Pack for real cold: a warm coat, boots with grip, a hat and gloves. See Montreal in winter.
March
Still winter for much of the month, with thaws and slush. It’s quiet for visitors, which makes museums and restaurants easier. Waterproof boots matter more than in January.
April and May
Spring arrives unevenly. Some days are cool and wet, others mild. Parks green up through May, and the outdoor patios start opening. Bring layers and a rain jacket.
June
Long days and the start of the festival season. Patios, parks and the Lachine Canal path get busy, and hotel prices start rising. Book early if your dates fall during a major event.
July and August
Peak season. The Montréal International Jazz Festival, Just for Laughs and Osheaga are all in summer. Expect warm, sometimes humid days and the most crowds of the year. Book rooms well ahead and start sightseeing early in the day. Warm nights are good for patios; see best areas for nightlife and the bars guide. See the festivals guide.
September and October
For many people, the best time to visit. Crowds thin out after Labour Day, evenings get cool, and Mount Royal turns colour from late September into October. Pack a warm layer for the evenings.
November
Grey, cool and often damp, and the quietest month of the year. It’s a good time for museums, free things to do, comfort food like poutine and cheaper rooms. Have a rainy-day plan ready.
December
Winter arrives, with snow likely later in the month. There are holiday lights and markets in places like Old Montreal. Some businesses close or shorten their hours around December 25–26 and January 1–2, including the public markets.
