Weather patterns on this route
This route crosses at least three distinct climate zones. The eastern slopes of the Rockies can see chinook winds that swing temperatures 20°C in hours. Rogers Pass (1,330m elevation) regularly receives heavy snowfall from October through April and is one of the most avalanche-prone highway corridors in the world. The Coquihalla connector and Fraser Canyon can have freezing rain when the valley floor is warmer than the upper elevations. The Fraser Valley approaching Vancouver is typically milder but prone to heavy rain and fog.
Seasonal driving tips
Winter
Winter tires are legally required on most BC highways from October 1 to April 30. Rogers Pass can close for avalanche control — check DriveBC before departing. Carry chains for the mountain passes. The temperature can drop 15-20°C between the valley and the summit. Budget extra time; winter conditions can easily add 2-3 hours to the drive.
Summer
Summer is the most reliable season for this drive, but afternoon thunderstorms can develop in the Rockies. Wildfire smoke from BC's interior can reduce visibility in July and August. Construction is common on the Trans-Canada through the mountain sections. Start early to cross the passes in cooler conditions.
