Upper Blue Lake Campground
Campground · Yosemite corridor
Upper Blue Lake Campground sits at 8,209 feet in the Sierra Nevada's Yosemite corridor, sheltered by granite ridges on the eastern flank of the high country. Wind exposure is moderate compared to exposed alpine lakes at similar elevation.
Wind averages 11 mph and peaks in afternoon hours as thermals draw air off the lake. Morning calm dominates from dawn until mid-day; afternoon gusts funnel through the drainage by 2 PM. Cold persists even during warm spells; the 30-day average sits at 29 degrees Fahrenheit, well below valley floor temperatures.
Over the past 30 days, conditions averaged a NoGo Score of 18, with temperatures at 29 degrees and average wind of 11 mph. The week ahead shows typical late-spring volatility: warming trend mixed with afternoon wind pulses. Crowding remains light (30-day average 12), though weekend traffic increases when Highway 120 access stabilizes.

About Upper Blue Lake Campground
Upper Blue Lake Campground occupies a granite bench above the lake's north shore at 8,209 feet, accessible via Highway 120 through Lee Vining and the Tioga Pass corridor. The campground sits roughly 2 hours east of Yosemite Valley and serves as a jumping-off point for the high Sierra backcountry. Access is seasonal; Highway 120 typically opens in late spring and closes in autumn, making this location inaccessible during winter and early spring months. The nearest town with services is Lee Vining, approximately 50 miles west.
Spring and early summer bring rapid warming and snowmelt, pushing temperatures from the 30-degree winter average toward the low 40s. The 30-day average of 11 mph wind is typical for the high Sierra at this elevation. Maximum wind gusts reach 26 mph, most pronounced in afternoons when thermals climb the eastern ridgeline. The campground remains in shadow until mid-morning, and afternoon sun accelerates both melt and wind generation. Late summer sees the lowest wind and clearest skies, with temperatures climbing into the upper 30s and lower 40s. Crowding averages 12 visitors in the rolling 30-day window and remains light compared to valley-floor camps, reflecting the location's remote position and road-access limitations.
Upper Blue Lake Campground suits anglers, backcountry hikers staging into the high country, and campers seeking relief from valley crowds without extreme technical terrain. Expect cold nights year-round (minimum temperature on record is 13 degrees Fahrenheit) and afternoon wind strong enough to complicate small-boat paddling or photography. Parking is limited; arrive before 10 AM on weekends to secure a site once Highway 120 fully opens. Water and pit toilets are the standard amenities; no generators or commercial services operate on-site. Snow lingers in shaded pockets through June; verify road and trail conditions before committing to a visit.
Nearby alternatives include Lower Blue Lake, situated just downstream and slightly more sheltered from afternoon wind, and Ellery Lake to the north, which offers similar elevation and high-Sierra character with comparable exposure. For visitors seeking lower elevation and warmer temperatures, June Lake Loop lies 40 miles northwest and provides more protected camping and fishing access. Those pursuing high-altitude climbing or extended backcountry trips use Upper Blue Lake as a supply cache and staging area before pushing into the Sierra crest.
