Lake Frances
Lake · Yosemite corridor
Lake Frances sits at 10,410 feet in the Yosemite corridor's high Sierra. A glacially-fed alpine lake exposed to afternoon wind, it demands morning visits and calm-weather planning.
Wind accelerates off the open water by mid-afternoon, pushing gusts to 42 mph on typical days. The 15 mph average wind masks a sharp morning-to-afternoon swing. Visit at first light to catch calm; expect turbulent conditions after noon.
The 30-day average wind of 15 mph and score of 17 reflect a place that alternates between marginal and poor conditions. Temperatures average 21 degrees Fahrenheit across the rolling month. Watch for afternoon wind spikes; the next week ahead shows similar patterns with isolated mornings offering brief windows.

About Lake Frances
Lake Frances sits on the high east slope of the Sierra Nevada, drained by tributaries flowing toward the Mono Basin. Access is via Highway 120 from the west; the final approach is rough track and foot traffic from nearby trailheads in the Tioga Pass corridor. Base popularity is low (0.25 rating), meaning crowds are minimal even on weekends. The lake sits well above the tree line, fully exposed to weather systems moving across the range.
At 10,410 feet elevation, Lake Frances experiences a compressed season. The rolling 365-day record shows minimum temperatures of 7 degrees Fahrenheit and maximum temperatures of 34 degrees Fahrenheit; the 30-day average of 21 degrees is typical for late spring. Wind dominates the character. The 30-day average wind of 15 mph masks severe afternoon gusts (maximum recorded: 42 mph). Snow persists into early summer in most years, and the lake may remain partially frozen through May. Conditions improve markedly by late September when air is calmer and temperatures more stable, though afternoon wind remains the norm.
Lake Frances suits experienced high-country hikers and mountaineers comfortable with exposed terrain, thin air, and rapidly changing weather. Day-use visitors dominate; overnight camping is minimal due to sparse water and minimal shelter. Paddlers and swimmers need to plan around morning-only windows; afternoon wind makes the lake dangerous for small craft. Early-morning trips capture the best light and wind conditions. Later in the season (late September onward), conditions stabilize enough for longer stays, though afternoon wind still requires respect. Parking is limited and informal; arrive early or plan a weekday visit.
Visitors pairing Lake Frances with nearby objectives should consider Tenaya Lake (larger, slightly more sheltered) and the alpine lakes near Cathedral Lakes trailhead, both accessible from Highway 120. Lake Frances is more remote and windier than Tenaya, making it a choice for those seeking solitude over convenience. The exposure that drives afternoon wind also delivers unobstructed views of the Sierra crest. This lake is not a casual destination; it rewards planning and rewards early starts.
