Vancouver has a mild oceanic climate with wet winters and relatively dry summers. At the Vancouver International Airport composite station, the 1991-2020 reference averages range from a daily high of 44°F (7°C) in Dec to 72°F (22°C) in Jul. Monthly precipitation averages sum to 45.7 inches (1160 mm) per year.
Winter is the wet season: mild, gray, and dominated by Pacific storm systems, with rain in the city while snow piles up on the North Shore ski hills. Spring dries out slowly, with cherry blossoms by late March. Summers are remarkably dry and sunny with comfortable warmth, though wildfire smoke from the BC Interior can cloud late summer. Fall flips the switch back quickly, the first atmospheric rivers of October and November can arrive with startling force.
