Ski Report for Mammoth Mountain, California

Daily Ski Conditions for Mammoth Mountain, California

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.
