# Mammoth Mountain Snow Report: December 2025

Well folks, if you're thinking about heading up to Mammoth Mountain right now, here's what you need to know before you pack up the car and hit the road.

Currently, Mammoth is sitting with a 40-inch base at the lodge level, which honestly isn't terrible for late December but definitely not going to blow your mind. The resort has 13 of 24 lifts spinning and variable piste conditions—basically meaning some runs are holding up better than others depending on where the snow landed and how much traffic they've seen. If you're looking for untouched powder, the off-piste situation is pretty quiet at the moment, so manage your expectations there.

Here's the real story: the last 48 hours have been bone dry at lower elevations, with zero new snowfall reported. That said, things are about to get interesting. A system is expected to roll in around Wednesday afternoon into Thursday, potentially dumping up to 64 centimeters (about 25 inches) of fresh snow. Now that's the kind of news that gets skiers and boarders excited. The snow line is forecasted around 8,900 feet, so elevation is going to matter big time when this system hits.

Weather-wise, you're looking at clear skies through Tuesday with highs in the mid-40s to low 50s Fahrenheit—basically bluebird days but with that California sun that can get aggressive. Wednesday brings clouds and cooling temps, then the pow arrives. Temperatures are dropping into the high 30s by Thursday, which is perfect for keeping that fresh snow quality locked in.

The season has accumulated 40 inches total so far, which tracks with typical early winter patterns for Mammoth. Historically, December sees an average of 67 inches, so if this incoming system delivers as forecast, you could be looking at a pretty solid month overall. The 2022-23 season holds the all-time record with over 700 inches at the lodge and close to 900 at the summit, so there's always that local legend to aim for.

One heads-up: strong winds were reported Sunday, so lift operations might've been affected. Always check the morning report before heading out. The base elevation sits at 7,953 feet with the summit at 11,053 feet, giving you that elevation advantage where deeper snow typically sticks around longer.

Bottom line? Right now it's playable but not spectacular. By midweek though, things could change dramatically for the better. If you've got flexibility in your schedule, waiting until Thursday or Friday after that system clears could reward you with some seriously fun turns.
