Mammoth Lakes Weekend Conditions: May 3-4, 2026
Caution is the call this weekend. Temperatures range from 18 to 49F and winds are generally calm at 8mph or less, so the air is fine and skies are dry. The cold is the story. Lows near 18F hit Monday morning, and 61% of locations across the corridor have safety floors active both days, so layering is not optional.
Where to Go
Adobe Reservoir (6,693ft, NoGo 7.1) is the top pick of the weekend. Zero wind, temps averaging 33F, and clean air with AQI 12. Shore fishing here can be good for rainbow trout in early May as the water warms slightly from winter, and with no wind to deal with, you can actually cast where you want. Kayaking and paddling are workable if you dress for the water temp.
Lee Vining (6,781ft, NoGo 8.0) is the warmest recommended stop at an average of 46F with just 3mph wind. It sits right off Highway 395 if you're driving up from LA or down from Reno, so it makes a natural base. Mono Lake (6,382ft, NoGo 8.2) is right next door at the same temps. Both are great for birding and walking the tufa formations this time of year, with spring migrants moving through.
Old Shady Rest Campground (7,838ft, NoGo 8.1) rounds out the top three. Zero wind, 32F average, and among the quietest locations in the data. If you want a basecamp inside the Mammoth area, this is your spot. The Mammoth Lakes Basin trail network is accessible from here, and hiking the lower loop toward Sherwin Lakes Trailhead (NoGo 10.3, 38F, 2mph wind) is a solid Saturday morning objective before afternoon temps drop again. Stay below 8,500ft for hiking. Crooked Meadows CG (8,839ft, NoGo 8.1) and Sagehen Meadows CG (8,445ft, NoGo 8.1) are also excellent if you want a quieter backcountry camp with minimal wind.
McGee Creek Trailhead (7,894ft, NoGo 9.4) is a good hiking launch point toward the McGee Canyon. Expect 34F and 5mph wind at the trailhead. The trail is a classic early-season option before snow consolidates the upper canyon. Brown and rainbow trout fishing in McGee Creek picks up in May, so bring a rod.
Where to Skip
Skip June Lake (7,621ft, NoGo 35.0) and Twin Lakes in Mammoth (8,580ft, NoGo 35.0) this weekend. Both hit the bottom of the rankings with NoGo scores of 35. The safety floor flags are part of the issue, and neither location offers conditions worth the tradeoff when much better spots are available nearby.
Virginia Lakes Trailhead (9,770ft, NoGo 35.0) is also a no-go. Wind at 11mph, light precip, and temps that will freeze overnight make this a trip to push to late May. Similarly, skip Mammoth Mountain (8,963ft, NoGo 35.0) and anything above 10,000ft. Locations like Little Lakes Valley Trailhead (10,243ft, NoGo 12.6) and Mosquito Flat (10,243ft, NoGo 13.1) are sitting at 19F lows with 13mph gusts, and 0.06 inches of precip hits some of the Rock Creek basin lakes above 10,500ft. That is sleet or snow at those elevations this time of year.
Taylor Canyon CG (7,392ft) is also worth skipping despite the mid elevation. Winds gusting to 22mph make it one of the windier spots in the 7,000-9,000ft band this weekend.
Bottom Line
Head to Adobe Reservoir for great fishing conditions or Lee Vining for the calmest, most enjoyable birding conditions. Dress for lows near 18F overnight, and stay below 8,500ft for hiking and fishing.
