Weather factors to check
- Fall and winter Pacific windstorms that down trees and knock out power
- Late-summer wildfire smoke from the BC Interior degrading air quality

Vancouver Air Quality App
Air quality is part of everyday weather planning, especially for workouts, commuting, wildfire smoke, heat, and sensitive groups. A local forecast should make that context easy to act on in Vancouver.
Local Air Quality Answer
Quick answer for Vancouver air quality
Air quality planning in Vancouver works best when weather context is included, because heat, humidity, wind, smoke, dust, and stagnant air can change outdoor risk quickly.
When conditions can shift
The October-March atmospheric-river season, midwinter arctic outflow snaps, and August-September smoke episodes are the periods when Vancouver forecasts matter most.
Best planning uses
- Tracking atmospheric-river rain and flood alerts
- Monitoring air quality during wildfire smoke episodes
- Comparing city rain with North Shore ski-hill snow
- Planning around windstorm power outages and ferry disruptions
Air quality changes how weather feels
For Vancouver, temperature, humidity, wind, and air quality together determine whether outdoor plans feel comfortable or risky.

Local Weather Context for Vancouver
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.

Local Hazards to Watch
- Atmospheric-river rainstorms that trigger flooding and landslides
- Fall and winter Pacific windstorms that down trees and knock out power
- Arctic outflow cold snaps that bring paralyzing snow and ice to a rain city
- Late-summer wildfire smoke from the BC Interior degrading air quality

Radar and Alert Context
Terrain dominates local radar: the North Shore mountains wring extra rain and snow out of every system, so conditions can differ sharply between Richmond's flats, downtown, and the mountain neighborhoods.
