What is Montreal summer forecast 2026?

Montreal's summer 2026 weather is trending to be slightly cooler and wetter than the summers of recent years.

With temperatures averaging near or just below seasonal norms, the season looks to alternate between cooler spells and short, intense bursts of heat.

Is summer 2026 going to be hot in Montreal?

As a general rule, Quebec receives between 75 and 100 mm of rain in June. 

In the Montreal area, for example, the monthly average sits around 90 mm.

Those hoping for endless sunshine may be a little disappointed in June 2026, as long stretches of stable, sunny weather appear to be far less frequent this year. 

Expect more clouds—and more precipitation.

Since 2015, Quebec has averaged about 21 thunderstorm days in June, and this year looks set to be similar, meaning storms should make regular appearances throughout the month.

The key difference lies in intensity: severe storms are expected to be less frequent. 

On average, Quebec sees about six days of severe weather in June, but that number is forecast to decline this year—good news for reducing the risk of major storm damage.
