Red Top Lake
Lake · Yosemite corridor
Red Top Lake sits at 7,953 feet in the Yosemite corridor's high Sierra. This glacially-fed alpine lake is smaller and more sheltered than the exposed water bodies directly east, making it calmer on average through the afternoon wind window.
Wind typically builds mid-afternoon as upslope flow accelerates off the surrounding ridges. Mornings are calm; by 2 pm sustained wind often reaches 12 mph with gusts to 35 mph. Cold air pools here even when Yosemite Valley is warm; expect temperatures 15 to 46 degrees Fahrenheit across the year. Early starts pay off.
The 30-day average wind is 12 mph with the NoGo Score averaging 14. Over the last month, conditions swung from a low of 6 to a high of 28, typical of spring transition when snow melt cools the lake and pressure systems are volatile. The week ahead should follow the same afternoon-wind pattern; check morning calm windows before committing.

About Red Top Lake
Red Top Lake lies in the high Sierra above the Yosemite corridor, reached via Highway 120 toward Tioga Pass. The lake sits at 7,953 feet elevation on a glacially-carved bench, surrounded by granite peaks and snowmelt drainages. Primary access is from the east via Mono County roads or from the west via the Highway 120 corridor; both approaches require high-clearance vehicle or hiking the final miles depending on snowpack and season. The lake is a destination for cold-water fishing, photography, and backcountry camping, not a roadside stop. Crowds here are minimal; base popularity is 0.25, meaning it sees a fraction of traffic at Tenaya Lake or Cathedral Lake to the west.
Conditions at Red Top Lake are driven by elevation and exposure to the Sierra crest. The 30-day average temperature is 30 degrees Fahrenheit; the year-round range is 15 to 46 degrees, far colder than Yosemite Valley at the same date. Wind is the dominant daily variable. Morning hours (before 10 am) are typically flat calm. By midday, upslope winds accelerate as solar heating on the east face pumps air westward; the 30-day average wind is 12 mph, but sustained gusts to 35 mph are common by 3 pm. Crowding averages 6 on the rolling 30-day window, reflecting the low base popularity and remote access. Snow lingers into late spring; water remains ice-cold year-round. Late September through early November brings the clearest, most stable weather; winter snowpack closes approaches; late spring (May onwards) opens water access but brings afternoon wind ramps.
Red Top Lake suits cold-water paddlers, backcountry anglers, and photographers seeking solitude and granite scenery. Pack for afternoon wind if you're on the water; plan to launch at dawn and be off the water by early afternoon. The lake is too remote and cold for casual day-trippers. Parking near the trailhead fills rarely, but access roads may be snow-gated or muddy; confirm Highway 120 conditions and local road status before driving. Altitude sickness is a risk for visitors arriving from sea level; allow a day to acclimatize. The lake drains to Mono Basin; the water is clear, cold, and oligotrophic (nutrient-poor), supporting only hardy native fish species.
Nearby alternatives include Cathedral Lake and Tenaya Lake to the west (both more accessible and warmer), and the Mono Basin lakes to the east (Mono Lake, June Lake, Convict Lake). Red Top Lake is the choice for experienced visitors who want high-Sierra solitude without the crowds of the main Yosemite corridor destinations. Compare conditions here to Tioga Lake, which sits at similar elevation but has more open water and stronger afternoon wind exposure. The Yosemite corridor as a whole favors early-week visits and early-morning activity windows; Red Top Lake follows the same pattern with even more pronounced calm-window advantage to planning.
