Tallulah Lake
Lake · Yosemite corridor
Tallulah Lake sits at 9,885 feet in Yosemite's high Sierra, a glacially-fed alpine water body exposed to afternoon wind and afternoon thermal loading. Winter and early spring dominate here; summer is calm and crowded.
Wind accelerates off the water by mid-afternoon, driven by thermal gradients between the lake and surrounding peaks. Morning conditions run flat and cold. Exposure is direct; the lake has minimal lee terrain. Expect 30 mph gusts during afternoon heating and calmer spells only before 11 a.m.
Over the past month, Tallulah Lake averaged a NoGo Score of 16.0 with wind at 11 mph and temperature at 25 degrees Fahrenheit. The 30-day max wind reached 30 mph. The week ahead will show whether afternoon thermals persist or whether a weather shift brings calmer, warmer days. Plan around the typical afternoon wind surge and early morning windows.

About Tallulah Lake
Tallulah Lake is a high-alpine lake basin in the Yosemite corridor of California's Sierra Nevada, sitting 9,885 feet above sea level. Access is primarily via California Highway 120 (Tioga Pass Road) from the east or Highway 395 approach. The lake drains north into the Lyell Canyon system. The setting is open tundra-like terrain with minimal tree shelter; surrounding peaks rise to 11,000 feet and above. Gateway towns are Lee Vining (east) and Tuolumne Meadows area (west). Most visitors approach from the Highway 120 corridor during the short summer season when the road is plowed.
Conditions at Tallulah Lake are governed by elevation and exposure. Winter and spring temperatures average 25 degrees Fahrenheit; overnight lows dip to 11 degrees Fahrenheit across the 365-day record. Summer highs reach 39 degrees Fahrenheit. The 30-day average wind is 11 mph, but gusts exceed 30 mph regularly, driven by afternoon thermal circulation off the water and funneling through the high-elevation basin. Early morning (before 10 a.m.) offers the calmest window; by mid-afternoon wind and chop dominate. Snow persists into May most years. Crowding averages 6.0 across the 30-day window, reflecting the remote access and short season.
Tallulah Lake suits hikers, climbers, and high-elevation alpine explorers who tolerate cold, wind, and isolation. Paddlers and swimmers are rare given water temperature. Most visitors are day-users accessing adjacent peaks or the Lyell Canyon drainage. Experienced high-Sierra travelers expect to start early (dawn), bank the morning calm, and descend or shelter by afternoon. Parking at trailheads is limited. The site demands route-finding skill and acclimatization to 9,885 feet. Smoke from summer fires in the Sierra can obscure the area; wind clears it quickly.
Adjacent high-alpine lakes in the Yosemite corridor include Cathedral Lake and Tenaya Lake to the west, and numerous tarns in the Dana Plateau to the north. Tenaya Lake is lower, warmer, and more sheltered. Cathedral Lake offers similar elevation and solitude but lies in a slightly protected canyon. Tallulah's defining trait is raw exposure and reliable afternoon wind; it is the least forgiving of the three for afternoon activity. Those targeting calm, warm high-Sierra lake experience should check Tenaya Lake conditions instead. Climbers on the Cathedral Range often pass through Tallulah's basin en route to higher peaks.
