Upper Geraldine Lake
Lake · Kings Canyon & Sequoia corridor
Upper Geraldine Lake sits at 9,206 feet in the Kings Canyon and Sequoia corridor, a high-Sierra alpine basin fed by snowmelt. Sheltered cirque topography keeps conditions calmer than the exposed ridges above.
Wind builds steadily from mid-morning through early afternoon, typically reaching 8 to 10 mph by noon. The lake's north-facing bowl funnels gusts off the water by 2 PM. Head here on early mornings or plan departures by 1 PM if wind sensitivity matters.
The 30-day average score of 14 and average wind of 8 mph reflect spring conditions at high elevation, where snowpack still governs access and afternoon thermals kick in reliably. The week ahead will follow the same pattern: calm mornings, building wind by midday, and crowding concentrated to weekends after the high passes open.

About Upper Geraldine Lake
Upper Geraldine Lake drains the Geraldine Lakes Basin on the eastern flank of the Kings Canyon and Sequoia corridor. It sits roughly 15 miles east of Highway 180 via Copper Creek Trail and requires a high-clearance approach or early-season foot access depending on snow. The basin sits in ESAC avalanche-center jurisdiction, though Upper Geraldine itself has no avalanche terrain. Access is most practical from late June onward when snow clears the approach, though the lake often holds ice or partial snow cover into mid-July.
Spring through early summer sees the coldest conditions, with 30-day average temperature of 30 degrees Fahrenheit and maximum wind gusts reaching 23 mph. The lake is typically frozen or snow-covered until mid-July; water temperature remains in the 40s Fahrenheit through August. The 30-day average crowding score of 5 reflects very light use even on weekends, owing to the steep approach and short season. Afternoon wind is the dominant seasonal trait; avoid paddling or fishing after 1 PM.
Upper Geraldine suits backcountry campers, high-Sierra trout anglers, and mountaineers staging for peaks above the basin. Experienced visitors plan for 5 to 7 nights at elevation, pack insulation for freezing nights year-round, and carry water treatment because snowmelt runoff can carry giardia. Parking at Copper Creek is tight; arrive by dawn on weekends. The approach is snow-covered until late June in typical years; confirm passability at the ranger station in Kings Canyon Village before driving east on Highway 180.
The Geraldine Lakes Basin connects northward to the Inyo National Forest high country and southward to Kearsarge Pass and the Sierra Crest. Visitors often pair Upper Geraldine with a traverse to Copper Lakes or a summit push to Peak 10,915. Lower Geraldine Lake sits 1 mile downstream and offers slightly warmer water and less exposure to afternoon wind, making it a practical lower-elevation fallback if conditions deteriorate.
