Montreal Weather in June

June weather in Montreal

June feels like the start of summer: warm afternoons, mild evenings and long daylight for wandering. The average high reaches 22°C, but rain falls on 16 days, so showers can interrupt a day out. Pack a small umbrella for walks around Old Montreal or Mount Royal.

You'll still have plenty of good days for the Lachine Canal bike path, outdoor terraces and a picnic in Parc La Fontaine. On sticky, rainy afternoons, skip a long uphill walk and duck into the Montreal Museum of Fine Arts instead. Families can enjoy the city's parks, but keep a flexible plan for wet weather.

Festivals and city life

June brings major events, including the Montreal International Jazz Festival, which often begins late in the month, and celebrations for Saint-Jean-Baptiste Day on June 24. The Canadian Grand Prix also takes place in June in some years, bringing crowds to Circuit Gilles-Villeneuve and downtown.

For music fans, the Jazz Festival's outdoor shows around Place des Festivals are a lively reason to visit. Expect busy streets and transit near event sites. If you're travelling with children, Parc Jean-Drapeau offers room to escape the downtown crowds between events.

Crowds and practical tips

June is busier than May as summer visitors arrive, and hotel prices tend to rise around big events. It's not usually as crowded as peak July, but Saint-Jean-Baptiste celebrations and the Grand Prix can make certain weekends feel packed. September is often a calmer choice.

For a budget traveller, compare dates around major events before choosing your stay. The Metro's Jean-Drapeau station is a handy way to reach the island for the Grand Prix; expect more crowded trains around race time. At the Old Port, wet paving can make long walks less pleasant, so keep a café stop in mind.
