Daily Ski Conditions for Mammoth Mountain, California
Mammoth Mountain is shaping up with cozy, early-season vibes that are perfect for those itching to drop into some fresh Sierra terrain this December. As of early December, the mountain's snow depth sits at about 102 cm (around 40 inches) at the summit near 3,369 meters (11,053 ft), and a more modest 30 cm (just under 12 inches) at the base around 2,424 meters (7,953 ft). The snow quality is described as gripping, so there's enough to get your edges into some fun turns, even if it’s still early-season and not fully dialed in yet[1][11].
Recent snowfall has been light with the last significant snow recorded back on November 22, and no new major accumulations in the past 24 to 48 hours. This means the mountain has a decent foundational layer, but more buildup is definitely anticipated as the season ramps up[1]. The total snowfall for the season so far measures around 40 inches, which is on track for a typical early December start but room to grow quickly as storms arrive[11]. Historical context is promising, with Mammoth averaging roughly 67 inches in December and a very good snow season often yielding well over 400 inches for the whole winter if the weather cooperates[3][6][7].
Right now, roughly 31 kilometers of groomed slopes are open out of Mammoth’s 89.8 km total terrain — that's about 35% — giving true locals and visitors a good taste of what’s to come while the full mountain continues to build snow. Correspondingly, 9 out of 25 lifts, about 36%, are operational, which generally covers key lifts in the core beginner and intermediate areas plus some stronger terrain for the advanced skiers and riders[1]. The Valley Run is presently open, allowing for some nice continuous runs.
Today's temperature is chilly but manageable, hovering between about -7°C near the summit and close to freezing at the base during the day. The weather is mostly calm with a mix of clouds and clear spells, which is typical for early December in Mammoth where cold high-pressure systems can settle in. The next five-day forecast is dry with no significant snow predicted, temperatures daily ranging from lows near -4°C to highs of around 3-5°C at higher elevations, so conditions will likely firm up — expect some freeze-thaw cycles that make for a crisp morning surface turning slushy by afternoon in spots[1][2][5][8]. As such, off-piste conditions can be variable; fresh powder may be preserved in shaded, protected bowls, but sun and wind may create some wind crust layers or firm pack elsewhere, especially as the season is still waxing on snow depth[5].
Mammoth’s snowmaking operations have been active and are a cornerstone of their early season strategy, filling in terrain to get lifts and runs open even in lean natural snowfall years. Snowmaking supports 46 trails with consistent coverage from late October through at least February, helping ensure that early season skiing is viable, especially around Thanksgiving and into December, which is great news for those planning trips now[3][9].
Other perks for visitors include a mix of terrain for all skill levels — from 25% beginner slopes to 40% intermediate and 35% advanced/expert terrain — plus a selection of terrain parks with eight parks loaded with jibs, jumps, and three halfpipes (though some features like halfpipes may be selectively closed early season). Night skiing is currently not available and cross-country and sledding runs have not opened yet, but the season is young and builds steadily through winter[1][3].
Visitors should keep layers handy for fluctuating temperatures and footwear ready for some icy or firm snow patches in the mornings. It's also wise to check daily lift reports and trail openings as these can change quickly with weather. The mountain plans to stay open at least through early June 2026, and signs po
