Prosser Group Campground
Campground · Lake Tahoe corridor
Prosser Group Campground sits at 5778 feet in the Lake Tahoe corridor's Sierra Nevada, offering shelter from afternoon wind funnels that rake the open lake to the east.
Wind accelerates from the northwest by mid-afternoon as the lake heats. Morning calm persists until roughly mid-day. At this elevation, temperature swings 20+ degrees between sun and shade. Afternoon gusts can exceed the 8 mph rolling average.
Over the past 30 days, conditions here averaged a NoGo Score of 12.0 with wind at 8 mph and temperature near 41 degrees Fahrenheit. The week ahead will test whether those patterns hold or shift toward higher crowding as late spring approaches. Watch for afternoon wind to climb on clear days.

About Prosser Group Campground
Prosser Group Campground occupies a sheltered draw in the high Sierra east of Highway 89, approximately 20 miles north of the Highway 50 junction near South Lake Tahoe. The site sits inland from the main lake body, which shields it from the full force of afternoon thermal wind that dominates the open water and western shoreline. Access is via a short dirt or rough gravel spur; high-clearance vehicles handle the approach better than sedans. The nearest gateway is South Lake Tahoe, roughly 30 minutes south; Truckee to the north offers alternative lodging and services.
Spring conditions at this elevation bring temperature swings. The 30-day average sits at 41 degrees Fahrenheit, but overnight cold persists into late spring; expect frost in early mornings and melt-off by afternoon. Wind averages 8 mph over the rolling 30 days but peaks at 20 mph on exposed days. Crowding is light to moderate at a rolling 30-day average of 6.0, but weekends fill faster as Highway 89 becomes consistently passable. Snow persists at this elevation longer than the lake basin; check drainage and mud conditions before committing.
Prosser Group Campground suits small group camping and serves visitors targeting the quieter east side of the Tahoe corridor. The site works best for parties arriving Tuesday through Thursday morning, when wind is typically calmer and crowding drops. Afternoon activities should plan around the thermal wind that picks up by mid-day; paddlers and light-craft operators should leave the water by early afternoon. Parking is limited; arrive early on busy weekends or book in advance. Smoke from Sierra fires can degrade visibility in late summer and early fall, reducing appeal during those months.
The nearby Tahoe basin offers a spectrum of elevations and exposures. The open lake to the west experiences stronger wind and higher crowding; inlets and coves closer to South Lake Tahoe can be more congested but see more services. Higher camps in the Sierra crest zone north and east of Prosser sit above treeline and face full exposure to wind and weather. For visitors seeking reliable shelter and lower pressure, Prosser splits the difference: sheltered enough for group camping, raw enough to feel remote.
