Montréal Climate

Continental climate with dramatic seasonal swings. Summers (June–August) are warm and humid at 24–30°C with occasional thunderstorms. Winters (December–March) are severe, with temperatures regularly dropping to −15°C or colder and heavy snowfall that causes frequent de-icing delays and occasional ground stops.

Spring (April–May) and autumn (September–October) are transitional and relatively pleasant, though spring snowstorms are not unusual. Pack serious winter gear from November through March; ice storms in early spring create particularly difficult travel conditions.

Check current weather forecasts before travel.
