Boothe Lake
Lake · 9,888 ft · Yosemite corridor
Boothe Lake sits at 9,888 feet in the Yosemite corridor's high Sierra, a glacially-fed alpine lake exposed to afternoon wind and early-season snowpack. Access via Highway 120; typically quieter than lower Yosemite Valley lakes.
Wind builds steadily from mid-morning, funneling down the drainage by afternoon. The 30-day average wind is 13 mph, but gusts spike to 37 mph on exposed days. Morning calm lasts until roughly 10 a.m. on settled weather windows. Snowpack lingers through spring; avalanche terrain borders the approach.
Over the last 30 days, Boothe Lake averaged a NoGo Score of 35, with temperatures around 21 degrees Fahrenheit and wind holding at 13 mph on average. The week ahead will show whether warming trend and wind stability continue or reset. Watch the chart grid for wind spikes and crowding surges tied to weekend access and Highway 120 conditions.

About Boothe Lake
Boothe Lake lies on the eastern rim of the Yosemite corridor, at 9,888 feet elevation in California's high Sierra. The lake drains north into the Tuolumne River system. Primary access is via Highway 120 from the west; from the east side, approach via Highway 395 and Forest Service roads. The nearest gateway is Lee Vining, roughly 45 minutes to the east. Winter closure of Highway 120 restricts access from late autumn through spring; confirm road status before driving.
Spring conditions are dominated by snowpack and avalanche hazard. Winter temperatures at Boothe Lake drop as low as 8 degrees Fahrenheit; by mid-year, highs reach into the low 30s Fahrenheit. The 30-day rolling temperature stands at 21 degrees, typical for late April snowmelt season. Wind averages 13 mph across the month, but afternoon gusts regularly exceed 30 mph on clear days. The 30-day average crowd score is low at 6, reflecting the lake's remote position and difficult winter access. Expect crowds to spike sharply once Highway 120 opens fully and temperatures stabilize.
Boothe Lake suits backpackers and mountaineers seeking high-alpine solitude and glacier-fed water clarity. Day hikers are rare due to the approach length and elevation gain. Wind and snowpack dictate timing more than any other factor. Head here on calm mornings in late September and early October, when snowmelt has dropped but afternoon wind patterns remain predictable. Skip the afternoon if you're paddling or casting from shore; mornings offer 3 to 4 hours of flat water before wind picks up. Avalanche terrain flanks the approach; travel only after spring consolidation and during stable snow periods.
Nearby Tenaya Lake and Ellery Lake sit at similar elevation but receive heavier use. Boothe Lake's lower popularity score of 0.25 reflects its remoteness and access constraints. Experienced Sierra travelers pair Boothe with a loop toward the Cathedral Range or Lyell Canyon, using Highway 120 as the anchor. The lake's isolation and raw weather character appeal to self-reliant visitors comfortable reading snowpack, wind, and crowd timing from forecast data.
