What Affects Montreal Weather?

Lake effect: Proximity to the Great Lakes can produce intense localized snowfall and moisture in Montreal and surrounding areas.
Jet stream patterns: Shifts in the polar jet stream bring Arctic air masses in winter and warm, humid air in summer.
Urban heat island: Dense urban development means Montreal often records higher temperatures than surrounding rural areas, especially overnight.
Storm tracks: Low-pressure systems tracking up the St. Lawrence Valley and across the Great Lakes are responsible for most significant precipitation events.
