TL;DR
Mammoth Mountain has confirmed it will keep lifts running through at least Memorial Day 2026, despite a below-average snow season by its own standards. With 243 inches recorded so far this season and a summit sitting above 11,000 feet, California's high-altitude workhorse is doing what it does best — outlasting everyone else on the calendar.
Mammoth Mountain Will Stay Open Through at Least Memorial Day 2026
California's Mammoth Mountain has confirmed it will remain open for skiing and riding through at least Memorial Day 2026. The announcement, made via press release on February 26, 2026, won't come as a huge surprise to anyone who's followed this resort — Mammoth has a long history of running lifts deep into spring, and sometimes into June during strong snow years.
How the 2025/26 Season Has Stacked Up
It hasn't been a standout year by Mammoth's own benchmarks. The resort averages around 400 inches of snow per season, and at 243 inches season-to-date, they're sitting below that mark heading into March.
The season opened slightly above average but late — November brought 16 inches, a notable improvement on last October's 3 inches, though precipitation stayed quiet through much of that month. Things picked up in December (73 inches) and January (43 inches), before February delivered over seven feet of snow — 87 inches — which helped bulk out the season total considerably.
For context, the 2023/24 season logged 367 inches, and the 2022/23 season was the biggest on record at 715 inches. Last season's 286 inches still saw Mammoth run until June 15, so even modest snow years don't necessarily mean an early finish here.
