Tempo Dome
Peak · 7,851 ft · Yosemite corridor
Tempo Dome is a 7851-foot peak in Yosemite's high Sierra corridor, sitting above the glacially-sculpted terrain east of the park's main valley. Wind exposure defines its character.
Tempo Dome faces open exposure to afternoon wind funneling off the eastern high country. Morning hours tend calmer and warmer than late day. Snow lingers into early summer; spring snowpack instability is the primary hazard. Crowding stays light year-round owing to low base popularity and remote access.
Over the past 30 days, Tempo Dome has averaged a NoGo Score of 33, with wind averaging 8 mph and temperatures holding around 36 degrees Fahrenheit. The typical low score in that window was 6; the high reached 50. Look ahead for similar conditions through the next week, with wind rarely exceeding the 30-day max of 20 mph. Plan ascents for early morning to avoid afternoon gusts.

About Tempo Dome
Tempo Dome lies at 7851 feet in the high Sierra east of Yosemite Valley, accessed primarily via Highway 120 from the west or Highway 395 from the east. The peak sits in avalanche terrain managed by the Sierra Avalanche Center. Drive times from Yosemite Village run 90 minutes to the base trailheads; from Lee Vining or Mammoth, 2 to 3 hours. The Yosemite corridor designation reflects its position within the park's extended eastern boundary, where snow-fed creeks drain toward the Mono Basin. Low base popularity means parking and trail congestion remain manageable even during peak season.
Winter and spring dominate avalanche risk. Tempo Dome's terrain includes steep gullies and convex slopes prone to wind slab and wet slab failure, especially after new snow or rain-on-snow events. The 30-day average temperature of 36 degrees Fahrenheit reflects the current shoulder season; expect lows of 19 degrees Fahrenheit in winter and highs near 53 degrees Fahrenheit in summer. Wind averages 8 mph but can gust to 20 mph, typically accelerating after mid-morning as valley heating drives air up the eastern escarpment. Crowding remains minimal year-round, rarely exceeding the 30-day average of 3 on the 10-point scale.
Tempo Dome suits winter and spring mountaineers, ski tourers, and snowshoers with avalanche training and decision-making experience. Summer hikers find exposed, rocky terrain with limited water and exposed ridges vulnerable to afternoon thunder. Plan ascents for early morning departure to avoid wind; carry a weather radio for real-time updates on approaching systems. Avalanche rescue beacon, shovel, and probe are non-negotiable in snow. The 365-day wind maximum of 20 mph underscores consistent exposure; afternoon conditions deteriorate rapidly. Parties without mountaineering or avalanche training should avoid steep terrain above 7500 feet.
Nearby alternatives include Cathedral Range peaks to the west and the Mono Divide summits to the south, both offering similar high-Sierra character with comparable avalanche terrain and wind exposure. Climbers seeking lower-elevation, faster ascents favor peaks west of Highway 120 in the main Yosemite corridor. Those aiming for autumn windows should monitor the 30-day rolling trends; NoGo Scores swing from 6 (optimal) to 50 (marginal) based on wind and storm timing. Check Sierra Avalanche Center forecasts before any approach in snow.
