Montreal’s long-awaited terrasse season is nearly here, but anyone hoping for a smooth transition into summer weather might want to keep the raincoat handy.
According to a long-range forecast from the Farmers’ Almanac, June 2025 in Quebec is expected to bring a little bit of everything — from unseasonably cool mornings to thunderstorms and scattered sun. In other words, don’t expect consistency.
The Almanac, which uses a centuries-old blend of astronomical and mathematical data to make long-term weather predictions, says Quebec is in for an average temperature of 17 C (2 C below average) throughout the month.
Here’s a breakdown of what to expect:
June 1 to 3
Pleasant conditions to kick off the month, but scattered showers could follow.
June 4 to 7
Dry and generally nice weather, though mornings may be cooler than usual (possibly enough for a light jacket).
June 8 to 11
Things take a turn here, with thunderstorms in the forecast and the potential for localized flooding.
June 12 to 15
Back to more stable and seasonable conditions — think warm, not too humid, and relatively dry.
June 16 to 19
Expect more showers and possibly strong thunderstorms, followed by some clearing.
June 20 to 23
A calmer stretch with mild, pleasant weather.
June 24 to 27
Storms may roll through again before skies clear up heading into the final stretch.
June 28 to 30
Cloudy days with scattered rain showers expected to close out the month.
While these are long-term predictions and should be taken with a grain of salt, they still give us a rough idea of what kind of mood June might be in. In the meantime, keep the sunscreen and umbrella close as you’ll probably need both.
