Bergona Lake
Lake · Yosemite corridor
Bergona Lake sits at 10,341 feet in Yosemite's high Sierra, a glacially-fed alpine lake exposed to strong afternoon wind. Spring and early summer offer the calmest conditions.
Wind drives the day here. Mornings are typically flat; gusts accelerate after 11 a.m. and peak mid-afternoon as solar heating funnels air down the drainage. The lake's high elevation means cold persists even in summer. Expect 14 mph average wind, with days hitting 33 mph.
Over the last 30 days, Bergona Lake averaged a NoGo Score of 15.0, with temperatures hovering near 25 degrees Fahrenheit and average wind at 14 mph. The upcoming week will track similar patterns; plan morning visits to avoid afternoon gusts. Spring snowmelt and temperature swings remain the dominant factors shaping conditions.

About Bergona Lake
Bergona Lake lies in the high Yosemite corridor of California's Sierra Nevada, accessed via Highway 120 from the west. The lake sits at 10,341 feet in glacially-carved terrain near the Sierra crest. Primary access is from Tenaya Lake trailhead or the Tioga Road corridor when Highway 120 is open. The drive from Yosemite Valley takes 60 to 90 minutes depending on conditions and road status. The nearest gateway towns are Lee Vining to the east and Groveland to the west.
Spring and early summer dominate the best-use window. Winter and early spring bring heavy snow; Highway 120 closure is typical until late May. By mid-June, the lake is usually snow-free but the thermometer rarely exceeds 40 degrees Fahrenheit even in midsummer. The 30-day average temperature is 25 degrees and the maximum wind reaches 33 mph. Late September and early October offer the most stable conditions with lower crowding and warmer afternoons than early season. Expect afternoon wind every day; it is the defining constraint.
Bergona Lake suits alpinists, fishers, and high-country campers comfortable with exposed terrain and cold water. The lake drains into the Tenaya drainage and sits above timberline; there is no shelter from weather once you leave the trailhead. Experienced visitors plan all activities for the morning window before 11 a.m., then descend or shelter by early afternoon. Parking fills quickly on weekends in July and August; arrive by dawn or plan a weekday trip. Snow lingers on approach routes into early July, and afternoon thunderstorms are common in August.
Nearby Tenaya Lake offers similar elevation but slightly less exposure; it is warmer and calmer on average. Cathedral Lakes to the south sit at lower elevation and reach stable afternoon conditions sooner in the season. For visitors seeking true high-Sierra solitude and willing to manage wind, Bergona Lake rewards early starts and flexible timing. The 30-day average NoGo Score of 15.0 reflects the consistency of afternoon wind; pack layers and respect the wind forecast.
