Montreal’s 14-day outlook shows a shift from mild, unsettled early autumn conditions toward cooler, more stable air by the end of the second week, with daytime highs tapering from the low teens into the single digits Celsius as the St. Lawrence Valley settles into a seasonal pattern.
What’s the general trend over the next two weeks?
For the first week, Montreal will see a mix of sun and cloud with a few passing showers, as a series of weak systems slide through the region. Temperatures will hover near seasonal norms, around 10–12°C by day and 2–5°C overnight. The second week brings a drier, cooler air mass from northern Quebec, dropping highs to the 5–8°C range and bringing frost risk to outlying areas near the Ottawa River and Montérégie hills.
Will there be any significant rain or snow events?
No major storms are expected in the next 14 days. The most notable precipitation will be a light rain event around day 5–6, totalling 5–10 millimetres. There’s a slight chance of wet flurries early in the second week across the higher terrain of Mount Royal and the West Island, but accumulation is unlikely in the city itself. The live forecast above will catch any last-minute shifts in timing.
