Upper Sunrise Lake
Lake · Yosemite corridor
Upper Sunrise Lake sits at 9485 feet in the Yosemite corridor's high Sierra, a glacially-fed alpine lake that turns calm in early morning before wind rises sharply by afternoon.
Morning glass water gives way to sustained wind funneling off the open basin by midday. The 30-day average wind of 12 mph masks afternoon gusts reaching 33 mph. Cold water and steep granite banks define the character; expect snow lingering into early summer.
Over the last 30 days, Upper Sunrise Lake averaged a NoGo Score of 16.0, with temperatures holding near 24 degrees and wind averaging 12 mph. The week ahead will show how spring warmth and snowmelt push both wind exposure and crowding. Use the chart to spot calm mornings and flag afternoon deterioration.

About Upper Sunrise Lake
Upper Sunrise Lake lies in the high-Sierra Yosemite corridor at 9485 feet, fed by snowmelt and drained by tributaries into the Sunrise Creek system. Access is via Highway 120 through Tioga Pass, with the nearest gateway town being Lee Vining to the east or Yosemite Valley to the west. The lake sits roughly 2 hours' drive from the valley floor and requires backcountry travel or technical climbing to reach; it is not served by a maintained trailhead road. The location's base popularity is low, meaning crowding stays modest compared to famous alpine lakes in the corridor. Winter access closes Highway 120 typically from November through May, making the shoulder seasons and summer the only viable windows.
Weather at Upper Sunrise Lake tracks the high-Sierra pattern tightly. The rolling 30-day average temperature is 24 degrees Fahrenheit, with a year-round range from 12 to 38 degrees across the 365-day window. Wind dominates the daily cycle. Morning hours offer protected water as air masses settle; by midday, thermally driven flow off the open basin creates sustained gusts, with the 30-day average wind of 12 mph climbing to afternoon peaks that have reached 33 mph. Spring snowmelt typically peaks through early summer, lowering water temperature and raising creek volume. Crowding averages 6.0 across the rolling 30 days, well below the high-country median; the lake draws serious mountaineers and backpackers, not day-trippers.
Upper Sunrise Lake suits climbers, backcountry skiers during spring corn cycles, and experienced alpine lake swimmers tolerant of water temperature below 40 degrees. Plan for headlamp access in and out; the approach crosses steep terrain and talus fields that demand daylight for safe navigation. Parking near the Highway 120 corridor fills quickly in early summer when the highway opens; plan for limited pullout space and high turnover. The NoGo Score of 16.0 on average reflects the place's combination of wind exposure and cold; calm days are prized and tracked obsessively by the small community of regular visitors. Smoke from Sierra fire season typically arrives by August, degrading the view and air quality.
Nearby alternatives include Cathedral Lakes and other glacially-carved basins along the Tuolumne Meadows approach, which offer more developed trail access but higher crowds. Tenaya Lake, lower and more sheltered, sits closer to the valley but hosts measurably more visitors. Upper Sunrise Lake's minimal popularity and extreme position in the high-Sierra corridor make it a specialist destination; go here to escape the corridor's main traffic and tolerate the wind, cold, and scramble as the price of solitude.
