Buena Vista Pass
Peak · 9,336 ft · Yosemite corridor
Buena Vista Pass is a 9,336-foot Sierra Nevada peak in the Yosemite corridor, sitting at the boundary between alpine exposure and the rain-shadow protection of the eastern Sierra.
Wind accelerates here in afternoon hours as valley thermals draw air across the pass saddle. Morning calm gives way to sustained gusts by mid-day. The 30-day average wind of 10 mph masks afternoon peaks near 30 mph. Snow lingers through late spring; snowpack instability is a primary concern on approach slopes.
Over the last 30 days, Buena Vista Pass averaged a NoGo Score of 32 with temperatures holding at 27 degrees Fahrenheit and wind averaging 10 mph. The week ahead will likely mirror this pattern: stable crowding at 3.0, persistent cold, and morning windows before wind picks up. Watch the 7-day forecast for any dip below the 6.0 minimum score recorded in the rolling period, which signals a rare calm day.

About Buena Vista Pass
Buena Vista Pass sits on the crest of the Sierra Nevada at 9,336 feet, marking the transition between the Yosemite high country and the drier eastern slopes. Access is via Highway 120 (Tioga Pass Road) from the west or Highway 395 from the east. The pass itself lies on the park boundary; the nearest gateway on the west side is Yosemite Village, roughly 60 miles away by road. From the east, Lee Vining (Highway 395) offers the quickest entry point. The pass is primarily accessed as a driving destination or a brief stop during Tioga Pass transit; winter closure of Highway 120 is typical from November through May, making spring and early summer the only reliable seasons for vehicle passage.
The pass experiences true Sierra high-alpine weather: average temperatures hover around 27 degrees Fahrenheit in the 30-day rolling period, with extremes from 14 degrees Fahrenheit in winter to 42 degrees Fahrenheit in summer. Wind is the dominant feature. The 30-day average wind speed of 10 mph understates the diurnal pattern; calm mornings give way to afternoon gusts regularly reaching 30 mph as solar heating in the basins below drives air across the pass. Crowding remains light at an average of 3.0 persons per hour, reflecting the pass's role as a transit corridor rather than a destination. Late spring and early summer bring the highest foot traffic as Highway 120 reopens and visitors return to Yosemite; late September through October offers the most stable conditions with longer calm windows.
Buena Vista Pass suits backcountry skiers, climbers, and high-alpine hikers with avalanche awareness. Winter and early spring visitors must assess snowpack stability; the pass sits within avalanche terrain with exposed gullies on both flanks. The morning calm between sunrise and mid-day is the safe travel window. Afternoon wind creates wind-slab hazard and poor visibility; experienced parties plan to cross or descend by early afternoon. Parking is minimal; most visitors are in-transit. Bring high-wind gear, especially sun protection and layering; the pass funnels wind and creates rapid cooling. Smoke from lower-elevation fires in summer can degrade visibility from the peak; monitor air quality forecasts before committing to a summit push.
Nearby Tioga Pass (elevation 9,945 feet, 5 miles south) sits higher and typically slightly colder with more sustained wind exposure. Mono Basin peaks to the south offer gentler approaches but similar afternoon wind. For Yosemite-side visitors, Cathedral Range peaks to the west provide comparable elevation and alpine character with somewhat more stable conditions when accessed from the valley floor. Buena Vista Pass distinguishes itself by its direct road access and its role as the psychological threshold between the Sierra's wet west slope and the arid Great Basin.
