What to watch for on this route

In the planner, TripCaptain highlights forecast weather risks between Kelowna, BC and Calgary, AB and summarizes the analysis with a Hazard Score™ from 0 to 100. A higher score indicates lower forecast risk, without guaranteeing road conditions.

• Avalanche Closures: The Trans-Canada over Rogers Pass, at 1,330 m (4,364 ft), is one of the most active avalanche-controlled highways anywhere. It closes on short notice for scheduled control work — check the official pass status before you leave and plan for a possible wait.
• Deep Mountain Snow: The high passes see heavy, wet snowfall that cuts visibility and buries traction well into spring. Winter tires are required on this corridor from October to April, and posted traction laws can call for chains.
• Black Ice: Shaded curves and bridge decks glaze over when temperatures sit near 0 °C (32 °F) — most often at dawn and after dark. On clear, cold mornings it is nearly invisible until you are on it.
• Whiteout & Blowing Snow: Blowing snow at the summits and across the open prairie into Calgary can drop visibility below 100 m (330 ft) within seconds. Ease off, add following distance, and switch to low-beam headlights.

When to go, season by season

• Spring (Mar–May): Snow and avalanche control linger at the high passes into May. Leave in mid-morning once overnight ice has lifted, and keep winter tires on through April.
• Summer (Jun–Aug): The clearest, safest window. Passes are open and daylight is long. Leave early to stay ahead of afternoon mountain thunderstorms and summer roadwork.
• Fall (Sep–Nov): First snow reaches the passes by October and winter-tire rules take effect Oct 1. Conditions turn fast — check the pass status the morning you travel and carry chains.
• Winter (Dec–Feb): Deep snow, scheduled avalanche closures, black ice, and whiteouts, with cold snaps near −30 °C (−22 °F). Drive in daylight, plan around posted closures, and wait out storms rather than crossing the passes at night.
