Maclure Lake
Lake · Yosemite corridor
Maclure Lake sits at 11,447 feet in the Yosemite corridor's high Sierra, a glacially-fed alpine lake exposed to afternoon wind funneling down from the peaks. Cold and windy by default; mornings are calmer.
Wind dominates here. The 30-day average wind is 13 mph, with gusts reaching 37 mph in the afternoon as air flows off the surrounding ridges. Morning conditions are markedly calmer; plan water activities for dawn. Expect afternoon chop and strong crosswinds by mid-day.
Maclure Lake's 30-day average score of 17 reflects persistent wind and cold typical of high-elevation Sierra lakes in spring. Temperatures average 21 degrees Fahrenheit with morning lows around 8 degrees. The week ahead should hold similar patterns; mornings offer your best window for calm conditions before afternoon wind builds.

About Maclure Lake
Maclure Lake lies in the high Sierra Nevada within the Yosemite corridor at 11,447 feet elevation. Access is primarily via Highway 120 through Tioga Pass and the Cathedral Lakes trailhead near Tuolumne Meadows. The lake sits in open alpine terrain carved by glaciers, with minimal shelter from the surrounding peaks. Weather systems move through quickly at this elevation; afternoon wind is structural, not incidental. Parking fills on weekends; arrive early or plan a weekday trip.
Spring and early summer bring cold, windy conditions. The 30-day average wind is 13 mph with peaks at 37 mph; winter temperatures drop to 8 degrees Fahrenheit while summer highs reach into the low 30s. Snow lingers into late June or early July most years. Afternoon wind is reliable and strong enough to create whitecaps and chop; mornings are 5 to 10 degrees calmer and less gusty. Crowding averages 6 out of 10 during the 30-day window, spiking the first weekends after Highway 120 opens to summer traffic.
Maclure Lake suits hikers and backpackers willing to start early and experienced mountaineers scouting approach routes. Anglers find decent brook trout populations; fish early before wind kicks up. Paddlers should skip this lake or commit to pre-dawn launch windows. The exposure and temperature swings demand layers and wind-resistant gear even in July. Water temperature stays in the 40s Fahrenheit through summer. Crowds are lighter on Tuesday to Thursday mornings than on weekends.
Cathedral Lakes, just south, offers similar elevation and access but slightly more shelter from trees and ridges. Tenaya Lake on Highway 120 provides a lower-elevation alternative with warmer water and calmer afternoon conditions. Maclure Lake is best as part of a multi-lake Sierra backpacking loop rather than a destination in itself; the wind and cold reward preparation but punish casual visits.
