Millie Lake
Lake · Yosemite corridor
Millie Lake sits at 6988 feet in the Yosemite corridor of California's Sierra Nevada. A modest alpine lake, it stays calmer than open water at lower elevations and draws minimal crowds.
Wind funnels across the lake by mid-afternoon, with gusts typical in the 12 mph average range. Morning paddling and fishing are most sheltered. Afternoon exposure and temperature swings are the rule; expect cold even in warmer seasons at this elevation.
The 30-day average wind of 12 mph and average temperature of 30 degrees Fahrenheit frame Millie Lake as a cold, moderately breezy place year-round. The rolling 7-day forecast below shows daily NoGo scores, wind speed, temperature, and crowding patterns. Morning windows are your best bet; skip the afternoon if wind matters to your plan.

About Millie Lake
Millie Lake is a small, snow-fed alpine lake in the Yosemite corridor at 6988 feet elevation. It sits well above the valley floor and away from the main Highway 120 corridor that feeds Tioga Pass. Access is primarily via hiking or pack stock from the eastern Sierra trailheads; the lake is not accessible by car. The Mono Basin to the east and the high Sierra crest to the west frame the drainage. This is genuine backcountry, not a roadside stop.
Year-round, Millie Lake runs cold and windy. The 30-day average temperature of 30 degrees Fahrenheit reflects late-winter and early-spring conditions typical of April; the annual range spans 15 degrees Fahrenheit to 46 degrees Fahrenheit. Wind averages 12 mph but gusts to 35 mph are common, particularly in afternoons when thermal circulation kicks in. Crowds are minimal (rolling 30-day average of 6 out of 100), a function of the hike required and limited camping capacity. Late September through early October brings the most stable weather and clearest skies.
Millie Lake suits anglers, backpackers, and mountaineers who hike into the high Sierra and plan to linger. Expect to arrive via foot or horse, carrying all gear. Wind and cold demand layers even in summer. Fishing is the primary draw for day users; the lake holds trout. Overnight visitors should be self-sufficient; there are no ranger stations, rentals, or services. Parking is at the trailhead only, and access roads may be snow-blocked through May or June depending on water year.
Nearby high-Sierra lakes in the Yosemite corridor (Tenaya, Cathedral, Glen Aulin) lie at similar elevations but with steeper approaches or more exposed situations. Millie Lake is less trafficked than Cathedral or Glen Aulin, making it a good choice for solitude seekers willing to hike. Compare conditions with adjacent Sierra passes on Highway 120 to gauge whether the high-Sierra passes are clear; Millie Lake remains inaccessible until those routes open and snowpack recedes.
