Daily Ski Conditions for Big Sky Resort, Montana

# Big Sky Resort Snow Report - December 1, 2025

Well, well, well—if you've been itching to get your skis waxed and your boots broken in, Big Sky is finally delivering the goods! The resort opened for the season on November 26th, and Mother Nature has been cooperating with some fresh powder to kick things off.

Let's talk snow, because that's what really matters here. Big Sky received 2 inches of fresh snow overnight and has picked up 3 inches in the past 24 hours, with 4 inches landing in the past 48 hours. The base currently sits at a modest 15 inches, which is typical for early season, but the summit is sitting prettier at 50 centimeters (about 20 inches). Season-to-date, the resort has accumulated 9 inches total, and they've had 10 inches fall over the past 5 days. It's a solid start, and the machine-groomed terrain is maintaining decent conditions despite the relatively thin early-season base.

On the lift side, six out of 40 lifts are currently spinning, which gives you access to the valley run and some of the terrain near the base. Only 6 of the 250 kilometers of slopes are officially open right now, representing about 2 percent of the terrain, but that's perfectly normal for the tail end of November. The resort is operating its standard weekday hours from 9 a.m. to 4 p.m.

Here's where it gets interesting weather-wise. Today you're looking at partly cloudy skies with a high of 17°F and a low of negative 1°F—proper Montana winter territory. Tomorrow should stay partly cloudy as well, reaching 18°F. Wednesday is when things get spicy: the forecast calls for actual snow, with accumulation expected as temperatures hover around 22°F high and 18°F low. Thursday looks partly cloudy again with highs near 20°F.

What makes this moment particularly exciting is the long-range outlook. Big Sky's AI-powered forecasting model is predicting significantly above-average snowfall for the 2025-26 season, with projections between 300 to 325 inches at mid-mountain elevations. The model is forecasting temperatures two to four degrees below average, which is music to every skier's ears—that means better snow preservation and longer-lasting powder. January and February are looking exceptionally snowy, with predictions of 135 to 155 inches during those months. If the model proves as accurate as it has over the past three trial years, you could be looking at one of Big Sky's best seasons in recent memory.

Big Sky's terrain is legendary for a reason. The resort sprawls across 5,850 acres with 317 trails ranging from gentle beginner cruisers to absolutely gnarly expert runs. The average annual snowfall of 400 inches speaks volumes about why this place is a powder paradise. The famous Madison 8 chairlift—the longest eight-person chairlift in the world—will eventually shuttle you to incredible terrain, and the uncrowded slopes mean you won't be dodging crowds while you're hunting fresh lines.

For anyone thinking about the December holidays, here's a helpful tidbit: Big Sky historically has about 80 percent of its terrain open by Christmas. Given the promising early season snowfall and favorable long-range forecasts, this December is shaping up to be one of those years where early-season conditions actually deliver.

The vibe at Big Sky is laid-back and relaxed compared to some of the more crowded mega-resorts out there. Plus, being close to Yellowstone National Park means you've got stunning mountain views and the option to do snowshoeing or dog sledding when you need a break from the slopes.

If you're planning a trip, now is actually a solid time to get out there. The fresh powder is landing, temperatures are cooperating, and the forecast for the coming weeks suggests only more snow is on the way. This is shaping up to be a banner season, and you don't want to miss it.
