Lost Dog Lake
Lake · Yosemite corridor
Lost Dog Lake sits at 9,541 feet in the Yosemite high Sierra, a quiet alpine basin where wind and cold dominate the calendar. Fewer crowds than Tenaya Lake or Cathedral Lakes justify the elevation slog.
Wind accelerates off the open water by mid-afternoon, funneling down from the peaks to the east. Morning glass gives way to gusty afternoons. Cold persists; the 30-day average temperature is 34 degrees Fahrenheit. Snow lingers on the north shore well into early summer.
The 30-day average score of 15 reflects a location caught between snow season and wind season. The 30-day average wind is 8 mph, but gusts spike to 27 mph when the jet stream dips. The 30-day crowding average is 6, meaning solitude is the default. Watch the next 7 days for morning windows and afternoon retreat.

About Lost Dog Lake
Lost Dog Lake lies on the Yosemite high Sierra corridor at 9,541 feet, accessed via the Cathedral Lakes Trail from Tuolumne Meadows or the Lyell Canyon approach. Highway 120 is the main artery; from Tioga Pass (US 395), allow 90 minutes to Tuolumne Meadows. The lake sits in a cirque basin east of Cathedral Peak, away from the main tourist flow. Base popularity is low (0.25), meaning even summer weekends draw fewer visitors than the meadows or Mirror Lake below.
Conditions here are dictated by elevation and exposure. The 30-day average temperature of 34 degrees Fahrenheit reflects late-spring and early-fall reality; high-elevation snow lies thick until mid-June, and frost returns by late August. The 30-day average wind is 8 mph, but the 365-day maximum wind of 27 mph shows how afternoon thermals and jet-stream dips can whip the open water. Crowding averages 6 over the rolling 30 days, an order of magnitude lower than Tuolumne Meadows. Plan around snow depth in June, afternoon wind from July onward, and early closures in September when Highway 120 traffic thins.
Lost Dog Lake is best for backpackers and off-trail explorers willing to trade established trails for solitude. Day-hikers often skip it in favor of Cathedral Lakes, the more obvious destination. Anglers fish the inlet brook for small cutthroat. Camp sites are primitive and unbusy. Arrive before 10 a.m. if you're paddling or fishing; wind after noon makes the water choppy and the experience unpleasant. Water shoes are essential; the outlet is rocky and shallow. The 30-day minimum score of 6 marks the window when conditions align; the 30-day maximum of 31 signals high wind or cold or both.
The Yosemite corridor nearby offers tighter alternatives. Cathedral Lakes (main lake) lies two miles south and is busier by a factor of 4 or more. Tenaya Lake, lower and warmer, sees crowds surge by early July. Lost Dog Lake remains quiet partly because the trail is less obvious and the payoff less photogenic. Late September and early October offer the best balance of stable weather, lower wind (afternoon gusts still peak at 27 mph annually), and shoulder-season solitude before snow threatens again.
