Fleming Lake
Lake · 9,717 ft · Kings Canyon & Sequoia corridor
Fleming Lake sits at 9,717 ft in the Kings Canyon and Sequoia corridor of California's Sierra Nevada. A high-alpine lake with modest crowds and reliable afternoon wind.
Wind builds steadily from morning calm, peaking in mid to late afternoon as thermal circulation strengthens off the surrounding peaks. Morning paddling or fishing is substantially calmer than afternoon conditions. Temperature swings sharply between sun and shade; expect single-digit lows even in early summer.
Over the past 30 days, Fleming Lake has averaged 8 mph wind with temperatures near 34 degrees Fahrenheit. Most days score in the low-to-moderate range for conditions. The week ahead will show whether spring warming pushes temperatures higher or whether alpine cold reasserts itself; afternoon wind remains the dominant planning factor regardless of season.

About Fleming Lake
Fleming Lake lies in the high Sierra backcountry at 9,717 ft elevation, roughly 15 miles southeast of the Kings Canyon Highway (CA 180) gateway near Cedar Grove. Access requires either a multi-day backpack or a trailhead scramble from the Copper Creek/Sphinx Lakes approach; the lake is not a day-trip destination for most visitors. The location sits within the Kings Canyon and Sequoia corridor, a zone characterized by steep granite ridges, glacially-scoured basins, and sparse tree cover above 9,500 ft. Summer crowds thin noticeably at this elevation compared to valley-floor destinations; base popularity remains low year-round.
Fleming Lake's weather follows high-Sierra patterns: 30-day average temperature stands at 34 degrees Fahrenheit with average wind of 8 mph, though afternoon gusts regularly exceed 15 mph. Snow persists through May at this elevation; the lake typically remains ice-free from late July onward. Wind accelerates predictably in afternoon hours as solar heating drives thermals upslope from lower drainages. The 30-day average crowding score is 5, meaning the lake remains lightly used even during peak season weekends. Early morning conditions are markedly calmer than afternoon; a morning visit yields wind speeds 5 to 10 mph lower than midday readings.
Fleming Lake suits backpackers, high-alpine fishers targeting golden or cutthroat trout, and experienced mountaineers using the basin as a staging point for peak attempts. Visitors should anticipate overnight temperatures in the low 20s Fahrenheit even in mid-summer; afternoon wind makes late-day arrival difficult for paddlers or those setting camp. The lake's remote position means no services, water treatment, or escape routes once you commit. Solitude and technical access are the defining features; crowds are not a concern, but self-sufficiency is non-negotiable.
Nearby alternatives include Sphinx Lakes, reached via the same drainage system but at lower elevation with more reliable water flow in early season. Copper Creek drainage to the west offers similar alpine character with slightly less wind exposure due to ridge shelter. The Kings Canyon Highway corridor provides warmer, lower-elevation lake basins (Monk Lake, Princess Lake) as fallbacks if snow or cold force a retreat. Fleming Lake's defining advantage is isolation combined with straightforward (though steep) trail access once you reach the trailhead.
