After a cold winter and an unusually rainy spring, Quebecers wondering what kind of summer weather is coming now have a better idea — and it looks like things are heating up.
According to The Weather Network’s new 2025 summer forecast, most of Canada can expect warmer-than-usual weather between June and August. While parts of the Prairies could face extreme heat and drought, Eastern Canada (including Quebec) is in for a warm and humid season with more thunderstorms than usual.
The Weather Network says Quebec will likely see its first heat wave before Canada Day, especially around Montreal and Quebec City. The forecast calls for near- or slightly above-normal daytime highs, but it’s the nights that will feel warmer than usual, thanks to all the moisture in the air.
However, the warmth may not last. “We do not expect the heat to be persistent or severe this summer,” says senior meteorologist Doug Gillham. “Occasional cold fronts are expected to deliver periods with more refreshing conditions.”
As for the rain, some of it could come from tropical systems later in the season. While forecasters aren’t expecting an especially active hurricane season, the tail end of a storm or two could still bring heavy downpours to parts of Quebec.
In the meantime, May 2025 is set to become the least sunny month in over half a century in Montreal.
On the bright side, the province isn’t expected to face the same drought risks as Western Canada. Still, summer storms tend to be unpredictable and hit-or-miss, so some regions could end up drier than others.
All told, Quebecers can expect sticky nights, stormy afternoons, and a few surprise soakers throughout the season.
