Frog Lake
Lake · Yosemite corridor
Frog Lake sits at 7,982 feet in the Yosemite corridor's high Sierra. A shallow alpine basin ringed by meadow and low conifers, it offers exposed but typically calm morning conditions.
Wind rises off the lake by mid-afternoon as thermal currents build; mornings hold flat water. The 7-day average wind of 7 mph masks afternoon gusts to 21 mph. Cold lingers even in summer; the water remains snowmelt-fed through early season. Crowds are light year-round, concentrated on weekends after Highway 120 opens.
Over the last 30 days, Frog Lake averaged a 15-point NoGo Score with temperatures holding around 32 degrees Fahrenheit and wind near 7 mph on average. The week ahead follows the same high-altitude pattern: expect calm mornings, rising wind by 3 p.m., and no significant crowding pressure. This is typical spring-to-early-summer behavior for a 7,982-foot basin; afternoon thermals are the dominant variable to plan around.

About Frog Lake
Frog Lake lies in the eastern Yosemite corridor, accessed via Highway 120 from Lee Vining or Highway 395. The nearest reliable supplies are at Lee Vining, roughly 40 miles north. The lake sits in gentle meadow country below the crest; the surrounding terrain is low-angle tundra and sparse whitebark pines, not steep or dramatic. Base popularity is low relative to Tenaya or Mirror lakes; you will not fight for parking or shore space. The approach is non-technical; day use dominates. Winter road closures on Highway 120 isolate the location from November through May, making summer the operational season.
The 30-day average temperature of 32 degrees Fahrenheit reflects the tail end of snowmelt season. Frog Lake warms to the high 40s by midsummer but remains cold enough to shock; neoprene or immersion gear is standard through August. Wind averages 7 mph but peaks at 21 mph in the 30-day window, almost always arriving in the afternoon as the high-altitude sun heats the basin floor. Mornings are genuinely calm; the water is stillest from sunrise to 11 a.m. Crowding averages 6 out of 10, with spikes only the first weekends after Highway 120 opens. Spring storms bring fresh snow to the crest; plan for variable visibility and wind gusts in transitional weeks.
Frog Lake suits paddlers, swimmers in wetsuits, and day hikers working the surrounding meadows. The exposed location appeals to those who want high-Sierra character without extreme technical terrain or sustained scrambling. Wildlife viewers come for pikas, marmots, and occasional bighorn herds on the distant ridges. The shallow basin means no deep-water peril but also limited protection from afternoon wind; kayakers and stand-up paddlers should head out before noon. Parking is adequate and rarely full. The light foot traffic makes it ideal for those seeking solitude; compare that to Tenaya Lake, which fills parking by 10 a.m. on summer weekends.
Nearby alternatives include Cathedral Lakes and Tenaya Lake, both reachable from the same Highway 120 corridor. Cathedral Lakes offers more alpine drama and rockier terrain; Tenaya sits lower and warmer but draws far heavier crowds. Frog Lake occupies a middle ground: quiet, high, and cold, with wind that is annoying rather than dangerous. The location is best paired with a hike into the high meadows or a traverse toward the crest. Return by early afternoon to avoid the wind-driven chop. The Yosemite corridor itself opens and closes on Highway 120 weather; check road status before driving from the valley.
