Ski Report for Mammoth Mountain, California

Daily Ski Conditions for Mammoth Mountain, California

Fresh tracks alert: Mammoth is skiable with variable early-season coverage — the resort is reporting a roughly 40-inch season base and early operations are open, though upper-mountain terrain remains limited and conditions are a mix of soft packed snow, springlike runoff at lower elevations, and punchier—sometimes heavy—snow higher up. Mammoth’s official winter report and regional visitor updates have been describing a 40" season total base and early December opening operations, which matches local reports from Mammoth Snowman and the town tourism pages noting a solid early-season base.

If you like numbers: local aggregators and resort-sourced reports list base depths in the neighborhood of a foot (around 12") on groomed low areas with a larger season total cited as 40" — this reflects early-season patchwork coverage where some lower runs are thinner while mid and upper zones hold more snow. Recent snowfall has been modest: multiple forecast and local report pages show little to no new accumulation in the most recent 24–48 hour windows for much of the resort, and weekend precipitation has been a rain/snow mix with snow levels often above 9,000 ft — meaning heavy, wetter snow up high and rain or thin coverage lower down.

Lift and trail access is limited compared with peak season: OnTheSnow noted a small fraction of lifts open (for example 5 of 24 reported on a recent update) and weekend operations are focused on lower and mid-mountain terrain where coverage and snowmaking support exists. Local reports and the mountain’s winter report indicate that the mountain is operating lifts and terrain selectively while crews continue snowmaking and building the base for upper mountain openings.

Weather right now is transitionary — forecasts and mountain webcams show mild daytime temps with highs in the 30s–40s°F in the base and slightly colder at the summit, breezy southwest winds at times, and a near-term pattern of mixed rain and snow with higher-elevation accumulation possible if storm temperatures drop. Short-range models and long-range forecasts are calling for limited additional snow over the next couple of days but stronger Pacific systems are possible later in the week, so the five-day outlook is for fluctuating temperatures, periods of clouds and precipitation, and snow levels that will determine whether precipitation falls as rain lower down or snow at summit elevations.

On-piste conditions vary by aspect: groomed runs that are open are generally skiable and often firm to springy mid-day; early-season variable snow and heavy convert (dense) storms mean surfaces can be heavy and sticky in warmer windows and wind-affected and scoured on ridgelines. Off-piste and gladed terrain should be approached cautiously — tree wells and thin zones exist, avalanche hazard for steep, wind-loaded faces can increase after heavier storms, and locals emphasize staying together and being aware of snowpack variability. Snowmaking is active where temperatures permit, helping keep main runs skiable while crews build out the base for bigger openings.

Practical local tips: bring layered clothing and aggressive edges (steel edges help in denser or icy patches), check lift and trail status before driving up because upper mountain lifts open only after sufficient base is built, and be prepared for winter driving and chain requirements on Highway 395 at any time. Watch for mountain notices and daily mountain reports for timing of additional lift openings and terrain expansions as the season progresses.

Hey shredders, Mammoth Mountain is firing right now with a solid 12-40 inch base depth from the 7,953-foot base up to the 11,053-foot summit, perfect for carving those Sierra lines. Riders are lapping 13 of 25 lifts and a healthy chunk of 178 trails, including groomers like Fascination and Broadway with killer snowmaking coverage, though watch for rocks on entrances to runs like Solitude and Dropout. Fresh powder alert: 6 inches hit mid-Broadway on December 16, building a thick 2-3 foot base up top after some rain lower down—locals say it's heavy but prime for turns once it clears.

Today's vibe is partly cloudy with highs around 49°F and lows near 38°F, ideal for all-day sessions from 8:30am-4pm. Look ahead: expect mostly clear skies through the weekend with temps in the mid-50s°F, cooling to the 40s by mid-week, and a whisper of 1 inch new snow possible on Wednesday—prime for powder hounds. Pistes are smooth and firm on groomed runs like West Bowl and Canyon Lodge routes, but off-piste stays treacherous with rocks and variable light; stick to open terrain and avoid Cornice unless you're sending it carefully.

Season total snowfall is ramping up nicely toward Mammoth's epic 400-inch average, with December historically dropping 67 inches—snow guns are cranking on Broadway for more base building. Pro tip from the locals: upper mountain needs that next big storm for full glory, so pack layers and hit early to dodge afternoon fog. No major closures, but chains required on HWY 395—strap in for bluebird sends and that unbeatable apres buzz!

Fresh turns at Mammoth are happening but the mountain is still in early-season shape: summit and base depths are modest, recent natural snow has been light, several lifts and runs are open thanks to aggressive snowmaking, and a Pacific Northwest trough looks likely to bring more snow late this week and into the weekend.

Right now Mammoth’s official mountain report lists operations with a portion of the resort running and — as of the last public update — about 13 lifts expected to operate, reflecting a partial opening rather than the full mountain being available. Local condition reports from the Snowman on the ground describe groomed surfaces that are “firm and fast” early in the day and note that snowmaking has been key to opening runs out of Canyon Lodge and other corridors.

Measured snow depths reported by independent sites remain spotty this week; public summaries and long-range trackers show no consistent, current numeric base/summit depth published in the automated feeds I checked, which means depths vary by face and elevation and the resort is relying on snowmaking to build base coverage where needed. Season totals so far are modest compared with full winters, and Mammoth’s historical averages (about 400 inches seasonally and the resort’s very deep record years) are useful context but do not reflect today’s shallow early-season totals.

New snowfall has been light in the last 24–48 hours with most forecasts and trackers showing little or no accumulation in that window, though models and local forecasters expect light chances of snow today into a stronger, colder system arriving later in the week that could bring measurable snowfall—some services indicate the next chance for measurable snow around December 17–18 with additional follow-up from a Pacific Northwest trough over the weekend.

Current weather at Mammoth Lakes this week has been cool with daytime highs in the 30s–50s°F depending on valley versus summit and overnight lows dropping into the 20s or below; AccuWeather and local forecasts show daily swings and a pattern that will turn colder with the approaching trough. Expect summit temperatures substantially colder than the town—standard mountain lapse rates apply—so conditions up high will be more favorable for natural snow and snowmaking once colder air arrives.

Piste conditions for open runs are generally groomed, firm, and fast in the morning with man-made snow providing coverage on many lower and mid-mountain routes; several user reports mention variable coverage off-piste, rock exposure in places, and early-season thin spots that require cautious route-finding, especially on cornices and natural lines where rocks can be close to the surface. Avalanche danger in bound resort terrain is managed, but off-piste and backcountry travel always requires checking current avalanche forecasts and bringing proper gear.

For visitors: wear layered cold-weather gear for variable temps, expect firm morning groomers that soften in the afternoon when the sun hits, and be prepared for route closures or rocky exits on lower runs—locals recommend sticking to snowmaking-covered corridors until a substantial natural dump deepens the snowpack. Lift and trail openings can change quickly; check Mammoth Mountain’s live mountain report before you go for the very latest lift count, trail list, and any guest notices.

If you’re planning a trip, the short-range outlook is promising for more snow later this week into the weekend as a colder, wetter trough drops south from the Pacific Northwest, which should improve off-piste coverage and expand open terrain if the models verify. Keep an eye on the resort’s daily report and local forecasters for timing and snow totals so you can pounce on fresh turns when the Sierra delivers.

Here’s the lowdown on Mammoth Mountain as the locals would tell you: recent reports show a thin early-season base with the upper mountain substantially deeper than the lower, limited terrain open, and mostly clear, mild weather for now with a chance of a little snow later in the week — so plan for a mix of groomers, manmade snow, and some punchy spring-like crust in spots until a big storm arrives.

Current snow depth: Mammoth’s official winter report notes roughly 12–30 inches of base depending on location — many public reports list about a 12" base in the lower areas while the upper mountain and Main Lodge areas are being reported closer to 30" on recent local updates. Local observers have suggested deeper snow higher on the mountain in pockets where natural snow has accumulated and where snowmaking has been effective.

New snowfall: Most mainstream snow services show little to no new accumulation in the last 24–48 hours at Mammoth (0" reported on several recent updates), though scattered light upslope and localized cells have produced small amounts in isolated upper areas on recent days according to local forecast summaries.

Open lifts and trails: The resort is operating a partial mountain with roughly 13 lifts reported open out of the full complement (reports vary between sources around 13 lifts open) and limited trails — early-season counts have been around 70 trails recently in local notes but that varies day-to-day as conditions and grooming change.

Current weather and temperature: Morning reports describe clear skies turning partly cloudy later with mild daytime temps at lower elevations (Main Lodge often in the 40s–50s°F) and colder up top; summit temps are colder of course and can sit near freezing or below at night. Live mountain weather feeds show typical cold summit readings compared with warmer base temps during daytime.

5‑day forecast snapshot: Short-range models and mountain forecast pages point to mostly dry, mild days in the immediate 2–3 day window with a chance for light mountain snow later in the week (models indicate the next measurable shot of snow around the 17th–23rd timeframe in longer-range guidance), but these outlooks are fluid — check the mountain forecast before you drive.

Piste and off‑piste conditions: Pistes are largely groomed where open but early-season coverage means variable conditions — expect firm, groomed runs, wind-scoured sections, and patches of manmade snow and icy crust; off-piste remains spotty and unpredictable with shallow snowpack in many trees and chutes, so avoid unpatrolled areas unless you have local knowledge and avalanche info.

Season total snowfall: The season total cited in recent weekly local reports was modest — around 40" season-to-date in one local summary — but totals differ by reporting station and elevation; Mammoth’s long-term average is ~400" per season and the mountain’s long snowfall history means things can change quickly with the next storms.

Additional tips and notices: Snowmaking has been running on cold windows to build coverage on key runs; the upper mountain typically requires a significant multi-foot storm to fully open — expect a mix of groomers and limited upper-mountain access until deeper storms arrive. Off-piste safety is important: tree wells and shallow coverage raise risk, so carry beacon/shovel/probe and check avalanche bulletins before traveling out of bounds. Lift and trail counts change rapidly early in the season — call the mountain or check the live mountain report before heading up.

If you want, I can pull live telemetry for summit/base temps and the resort’s latest lift/trail map now and summarize the minute-by-minute update so you know exactly what will be open when you arrive.

Mammoth is riding a warm-but-improving early season: upper mountain base around 30" and Main Lodge/base area about 15", with a season total near 40" so far according to local reports and the weekly summary. The hill saw little new accumulation in the immediate 24–48 hour window — most large recent precipitation fell earlier in the week and webcams/local reporters show mainly clear, sun‑soaked days with pockets of fresh higher-up snow reported midweek forecasts. Lift and trail counts are mixed across sources: the resort’s updates and local trackers show roughly 15–24 lifts operating with about 70–80 trails open on recent reports, though some trackers list fewer lifts due to phased upper‑mountain openings, so expect variations day‑to‑day. Weather on‑mountain has been mild and mostly clear with daytime highs in the 40s–50s°F at town level and colder up high; daytime temps around 45–58°F in recent forecasts and overnight lows in the 20s–30s°F are expected. The 5‑day outlook trends mostly dry and partly cloudy through midweek with a weak system and light snow predicted around Dec 17 promising a small refresh (around an inch in some model runs), then clearer/colder weather after that — check updated forecasts before you go since mountain weather can change fast. Piste conditions are described as variable: sun‑affected groomers at lower elevations are spring‑like in the afternoons and can get slushy, while upper‑mountain groomers and shaded chutes are firmer with tracked powder pockets where recent storms left accumulations. Off‑piste terrain is a patchwork — some high‑elevation north‑facing bowls still hold soft snow and wind‑blown pockets, but many lower and exposed areas have wind crust or thin coverage and require careful route choice and avalanche awareness. Snowmaking has been active where temperatures allowed and has helped establish coverage on key runs and Broadway, which keeps the parks and lower lifts usable despite limited natural snow in valley areas. Important visitor notes: upper‑mountain access can be limited until a more robust base is built — expect phased openings and possible lift changes, carry layers for large temp swings, and plan travel with tire chains or AWD as travel conditions to Mammoth can vary when storms hit. For the most current minute‑by‑minute lift status, trail openings and live webcams, consult the resort’s mountain report and local snow reporters before driving up, since counts and conditions are updating frequently as snow and temperatures change.

Daily Ski Conditions for Mammoth Mountain, California

If you’re eyeing Mammoth Mountain for your next ski or snowboard adventure, here’s the lowdown on current conditions so you can plan your shred like a local. At the summit, snow depths are holding strong with roughly 30 inches of packed base, while down at the Main Lodge, it’s about 15 inches—enough to get the runs going but still early season coverage for the lower terrain. Recent snow has been a bit light, with no major dumps in the past 24 to 48 hours, but the mountain's extensive snowmaking efforts are humming, especially on Broadway and around MC Coy Station, thanks to ideal wet bulb temperatures that keep those snow guns pumping out fresh snow annually through February.

Today, you'll find 15 lifts spinning and ready to take you up Mammoth's 3,500 skiable acres, with about 60+ trails partially open and more terrain expected to come online soon as the season gains momentum. The groomers are reported to be doing a top-notch job, offering firm but friendly surfaces in the morning that soften nicely as the sun hits, perfect for early season fun on the piste. Off-piste or backcountry conditions can vary widely this time of year; shaded north-facing terrain tends to hold powder better, but the sun and occasional wind can quickly crust or soften snow in exposed spots, so pick your lines accordingly.

The current weather is chilly but manageable, sitting in the low 40s °F at the base during the day and dropping to the low 20s °F overnight, with mostly clear skies expected today—ideal for spring-like powder pursuits even in December. Over the next five days, the forecast calls for mostly sunny conditions and stable weather with highs in the low-to-mid 40s°F and nighttime lows dipping to the low 20s, giving a mix of crisp mornings with warming sunshine in the afternoons. There's no major storm on the radar just yet, but subtle snow showers could sprinkle a dusting here and there, especially towards the weekend.

The season total snowfall is tracking well for December, though still early by Mammoth standards. The mountain comfortably averages about 400 inches annually, with last season ranking as the snowiest on record—over 700 inches at the base and nearly 900 inches atop the summit—setting a high bar to keep riders smiling all day long. For 2025–2026, all signs point to a colder, potentially snowy winter as climate patterns lean toward weak La Niña, negative Pacific Decadal Oscillation, and a solar max, which historically bring wetter, colder storms to the Sierra Nevada, so powder hounds should stay optimistic for solid snowpack building through January and beyond.

One important note for visitors is awareness of some ongoing safety considerations on the mountain. Mammoth is a volcanic dome complex with some fumarole sites beneath the snow, which occasionally require closures for safety. Additionally, ski patrol continues to be vigilant after a recent avalanche incident in February 2025; while all runs are carefully monitored and patrolled, being prepared for rapidly changing conditions and respecting closed areas is essential.

For now, early season skiers and riders will enjoy excellent base coverage in the upper mountain, smooth groomed trails, solid snowmaking support, and sunny, crisp days with visually stunning views from California’s highest summit. Whether you’re carving groomers, charging steeps, or playing in the terrain parks, Mammoth Mountain is primed to deliver that classic Sierra snow experience as the winter gets rolling. Just don’t forget your layers—the cold snaps are real, but so is the sunshine!
