Siesta Lake
Lake · 7,949 ft · Yosemite corridor
Siesta Lake sits at 7,949 feet in the Yosemite corridor, a modest alpine lake with reliable afternoon wind and low baseline crowds. Calmer in early morning, windier than the open Sierra by late day.
Wind builds steadily through the afternoon, funneling off the lake by 2 p.m. Morning glass water lasts until mid-day. Temperatures hover in the low 30s to mid-40s across the year. Crowding stays sparse except near Highway 120 opening windows.
Over the past 30 days, Siesta Lake averaged a NoGo Score of 14.0 with temperatures around 34 degrees Fahrenheit and average winds of 7 mph. The week ahead follows typical spring patterns for this elevation: warming days, persistent afternoon gusts, and light crowds outside holiday weekends. Watch for wind spikes when storm systems clear through.

About Siesta Lake
Siesta Lake lies in the high Sierra on the Yosemite corridor east of Highway 120, accessible primarily from Tenaya Lake or via backcountry approach from the Cathedral Range. The lake sits at 7,949 feet in a modest glacial basin, well below the crest but high enough to experience Sierra-typical wind and seasonal snow. Drive times from the Highway 120 corridor gateway run 1 to 2 hours depending on trailhead. The lake sees steady but never crowded use; base popularity sits at 0.25, meaning it draws a fraction of the traffic at more famous Tenaya or May lakes nearby.
Conditions at Siesta Lake follow classic high-Sierra diurnal patterns. Mornings stay calm and cold, with temperatures averaging 34 degrees Fahrenheit over the rolling 30-day window. Wind averages 7 mph but ramps to 19 mph on active days, almost always from the afternoon onward. Snow lingers into late spring at this elevation; the 365-day minimum temperature of 17 degrees marks alpine nights even in early summer. Crowding averages 6 people per observation slot on a sparse scale, spiking only during the first weeks after Highway 120 reopens and around long weekends. Late summer and early fall offer the most stable weather windows.
Siesta Lake suits paddlers, backpackers, and photographers who prize calm water and solitude over established facilities. Early morning is the only reliable paddling window; afternoon wind makes launch risky after noon. Hikers access the lake as a moderate day trip or overnight destination; water stays too cold for swimming until late July. Experienced visitors plan arrival by 7 a.m. to secure calm conditions and avoid the afternoon wind spike. Parking at Highway 120 pullouts fills on weekends but rarely at capacity. Smoke from late-season fires can reduce visibility despite low crowding.
Nearby Tenaya Lake, just west on Highway 120, is larger and more exposed to afternoon wind. Cathedral Lakes and the Cathedral Range proper lie south and require longer approach; they offer more alpine terrain and higher elevation but similar wind and weather patterns. Visitors managing a multi-day Yosemite Sierra trip often pair Siesta with Cathedral Range traverses. Compared to Yosemite Valley lakes, Siesta benefits from higher elevation and lower user density but trades convenience for isolation.
