What to watch for on this route
In the planner, TripCaptain highlights forecast weather risks between Portland, OR and Bend, OR and summarizes the analysis with a Hazard Score™ from 0 to 100. A higher score indicates lower forecast risk, without guaranteeing road conditions.
- Heavy Cascade Snow: US-26 climbs past Government Camp near 4,000 ft (1,200 m), where heavy Cascade snow can trigger chain requirements and slow the crossing of Mt. Hood to a crawl.
- Freezing Fog: Freezing fog settles around the summit, coating the road in ice while dropping visibility below ¼ mile (400 m) with little warning.
- Black Ice: On the leeward descent toward the high desert, wet pavement refreezes into black ice after dark, especially between Government Camp and Warm Springs.
- High Wind: Open stretches across the high desert near Bend see gusts over 40 mph (65 km/h), unsettling for high-profile vehicles and trailers.
When to go, season by season
- Spring (Mar–May): Cascade passes still hold snow, and late storms can bring chain requirements over Mt. Hood. Leave mid-morning, after overnight ice clears.
- Summer (Jun–Aug): Best driving season. Clear passes and warm high-desert roads. Watch for afternoon thunderstorms near Bend and wildfire smoke in late summer.
- Fall (Sep–Nov): Conditions cool fast; the first Cascade snows arrive by November and freezing fog forms at the summit. Carry chains from late fall on.
- Winter (Dec–Feb): Peak hazard. Heavy snow, chain requirements, and black ice on the descent are common over Government Camp. Check official pass status and cross in daylight.
