Mammoth Weather Forecast & Discusion – 93546

Thursday July 2nd, 2026 @ 9 AM

Weather Summary: A warming trend is moving in for our Independence Day weekend.  Mammoth Lakes will be in the 80s, with the Mountain and Lakes Basin in the 70s, and Bishop into the mid to upper 90s during the afternoon hours. The EPS model has a few build-ups with a slight chance of an isolated shower over the high country into Saturday.

Detailed Local Weather Forecasts:

Main Lodge / Mammoth Lakes Basin,

Saturday & Sunday: Sunny, with a high near 96. Light and variable wind becoming southeast 5 to 10 mph in the morning.

The Longer Range: As we move into the middle of next week, the EPS ensemble has a moderate ridge to our south. As the ridge strengthens, heights come up in the Eastern Sierra, warming the area up a few degrees.

In time, the EPS model, along with the GEFS, takes the ridge and moves it over the 4 corners area and really strengthens the core of the high, bringing temps up a few more degrees. That would be when we see our warmest temps and encounter what we call the Dog Days of Summer.

The long-range EPS weekly models have the Eastern Sierra and the Owens Valley in for some precipitation once that 4 corners high sets up.

Let’s hope the entire Sierra gets wet this Summer; chances are better than average with the developing El Niño. Some good rains would put a big damper on wildfire season.

My advice is that if you live out of the area and are planning a trip up, it’s always best to plan it for the start of summer, not at the end. Seems more often than not, we get on-and-off days of smoke later in the summer and early Fall.

I hope you’re having a great Summer, Snowman out…

Steve Taylor the Mammoth Snowman, has called Mammoth Lakes home since 1990. With a passion for deep powder, big mountain storms, and Sierra sunrises, he’s spent over three decades living and breathing life in the Eastern Sierra. From chasing early morning face shots to dialing in snowpack patterns, Steve brings a seasoned local perspective that only comes with time on the mountain. In late 2004, Steve launched MammothSnowman.com — a grassroots site born out of his desire to share accurate snow and weather info with skiers and riders who love Mammoth just as much as he does. Over the years, it’s grown into a trusted source for real-time reports, forecasts, mountain photos, and insider tips. His daily updates, storm videos, and “boots-on-the-ground” style set him apart from generic apps and tourism-driven reports. When it’s dumping in Mammoth, chances are Steve’s out there riding it, filming it, or breaking it down for the community. Beyond the snow, Steve is deeply connected to the year-round rhythm of the Eastern Sierra. In the summer months, you’ll find him mountain biking, hiking alpine ridges, and exploring hot springs from Mammoth to Bishop. He’s also the founder of EasternSierraMountainBiking.com and SkiingTShirts.com — continuing to expand his mission of sharing the mountain lifestyle through local insight, community, and creativity. Whether you’re chasing storms or singletrack, Steve’s updates help you stay stoked and informed.
