Early risers in Montreal squinted this morning under the orange sun rising over the city, and since yesterday it’s been sunny and hot—hotter than we expected, hotter than we were prepared for. We really need to start taking sunscreen with us everywhere.
Everyone had said that June would be cold, dreary, and gloomy. But since Monday, the weather has been very summery, even though it still feels muggy, as if a thunderstorm were about to break out any minute. And next week is going to be hot, hot, hot. On Friday, June 5, 2026, it will reach 30°C for the first time this year in Montreal.
What’s in store for June 2026 in Montreal
Météo Média cites the U.S. National Oceanic and Atmospheric Administration (NOAA), which predicts the return of El Niño to the skies over Quebec in June. It’s a weather phenomenon caused by a thermal anomaly in the equatorial waters of the Pacific Ocean. In short, it will be very hot in Vancouver and below seasonal norms in Montreal.
Because of El Niño, the “perceived” arrival of summer—with consistent high temperatures between 23 and 25 degrees—has shifted from mid-June to the end of the month. Don’t panic; it’ll still be summer by the end of June 2026. It has to be, right?
Here are some figures for the forecast in Montreal for June:
- between 8 and 28 days of rain
- between 2 and 20 days of sunshine
- with high temperatures between 12 and 23 degrees Celsius
- 180 mm of rain
The first half of June is hot, hot, hot
The highs for the first half of June 2026 are very, very summery. Of course, we haven’t forgotten that it always rains a little—almost every day—and that we have to accept it because it’ll cool us off.
