What to watch for on this route

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

• Sierra Snow at Donner Pass: Atmospheric rivers drop snow by the foot at the 7,056 ft (2,151 m) summit, faster than plows can clear it. A storm that falls as rain in the valley is deep snow by the pass.
• Black Ice on the Grade: Midday melt refreezes on shaded curves and bridges after dark, leaving a clear glaze that is hardest to see at dawn and dusk on the long descent.
• Chain Controls & Closures: When the storm hits, traction laws go up and the pass can close outright, sometimes for hours. Knowing the official pass status before you leave is the difference between a 2-hour drive and being turned back.
• Summit Whiteout: Wind-driven snow near the summit can drop visibility below ¼ mile (400 m), erasing lane lines and the car ahead. Blizzard conditions build fast once a front reaches the crest.

When to go, season by season

• Spring (Mar–May): The Sierra winter runs late — heavy snow and chain controls are common into April. Check the pass status the night before and leave in a clear morning window between storms.
• Summer (Jun–Aug): The safest season. Dry roads and open passes. Watch for afternoon thunderstorms over the crest and wildfire smoke that can thin visibility. Carry water for slow traffic.
• Fall (Sep–Nov): Clear early, then the first storms arrive — often by early November. Carry chains after mid-October and leave before mid-afternoon to stay ahead of an incoming front.
• Winter (Dec–Feb): The leave-before-the-storm season. Snow by the foot, chain controls, and full closures are routine. Time your drive to a clear window, carry chains, and never try to beat a closing pass.
