Lady Lake
Lake · 8,946 ft · Yosemite corridor
Lady Lake sits at 8,946 feet in the Yosemite corridor of the Sierra Nevada, a glacially-fed alpine lake ringed by sparse forest. Wind exposure and cold temperatures define its character.
Lady Lake faces steady afternoon wind, typically 8 mph across the 30-day average but capable of gusting to 26 mph by late day. Morning paddling and fishing are calmer. The lake's high elevation keeps temperatures low year-round, averaging 30 degrees Fahrenheit over the past month. Snowpack influences access and avalanche hazard through spring.
The 30-day rolling average wind of 8 mph masks afternoon acceleration typical for this exposure. Temperature hovers near 30 degrees Fahrenheit, consistent with 365-day averages that swing from 17 to 42 degrees. The week ahead will follow the same pattern: plan morning outings and expect wind buildup by noon. Crowding remains light at an average of 6, a fraction of nearby Yosemite Valley traffic.

About Lady Lake
Lady Lake is a small alpine lake accessed via Highway 120 from the north or Highway 140 from Mariposa County to the south. The lake lies in the upper Yosemite corridor at 8,946 feet elevation, surrounded by sparse lodgepole and whitebark pine. Parking is limited and often full during the first weekends after Highway 120 opens. The approach involves a short but steep hike through avalanche terrain; snowpack persists well into spring. The lake drains north into the main Yosemite watershed. Trout populations are modest. This is not a destination for beginners or fair-weather visitors.
Conditions at Lady Lake are shaped by elevation and wind exposure. The 30-day average temperature of 30 degrees Fahrenheit reflects the lake's position above tree line with minimal shelter. Afternoon wind is reliable, averaging 8 mph but frequently exceeding 15 mph by mid-afternoon; gusts reach 26 mph in the rolling 30-day record. Early morning is the only calm window most days. Crowding remains light, averaging 6 on the NoGo scale, because the lake lacks the infrastructure and roadside appeal of Tenaya or Tuolumne. Snowpack is present through May most years, and avalanche terrain surrounds the approach; check the SAC avalanche forecast before heading up. Summer brings brief respite from snow but maintains wind and cold. By September, conditions stabilize; October brings the driest, warmest window before early season storms return.
Lady Lake suits experienced backcountry visitors comfortable with avalanche terrain and high-altitude exposure. The lake is best for anglers willing to hike early and finish by noon, and for packrafters or kayakers who understand wind dynamics. Expect no services, no cell coverage, and limited parking. Skip the lake entirely during active snow melt or after heavy precipitation. The high NoGo score average of 33 reflects wind and cold as consistent constraints, not occasional surprises. Bring insulation for 17-degree lows if you camp; afternoon thermals can swing to the low 40s only in midsummer. Water filtration is mandatory.
Nearby alternatives include Tenaya Lake to the north, which is lower and warmer but far more crowded. Cathedral Lakes to the west offer more shelter and similar elevation. Tuolumne Meadows lakes to the northeast are higher still and slower to clear of snow. For a comparison point, Lady Lake's 30-day wind average of 8 mph matches the Yosemite high country norm, but its exposure and lack of tree shelter make it windier in practice than similar-elevation lakes with ridge protection. Visit in late September through early October for the best overlap of stable weather, low snow, and tolerable cold.
