Ski Report for Big Sky Resort, Montana
Daily Ski Conditions for Big Sky Resort, Montana
Big Sky Resort in Montana is kicking off the early ski season with some solid snow and plenty of reasons for enthusiasts to get excited. Currently, the mountain boasts a snow depth of about **76 cm at the summit (3403 m)** and around **20 cm at the base (2073 m)**, offering a good foundation for the slopes ahead. The snow quality is described as "gripping," ideal for carving turns whether you're skiing or snowboarding. The most recent measurable snowfall was on December 5th, with light accumulations of just under 1 cm reported in the last 24 to 48 hours, so the mountain is holding steady with relatively fresh snow but no major storm in the immediate past day or two.
As for terrain availability, things are still gearing up—the resort currently has **21 km of its extensive 250 km of slopes open**, which is about 8% of total terrain. This is typical for early December, and visitors can look forward to this number increasing significantly as the season progresses. Similarly, **8 out of 40 lifts (around 20%)** are operating right now, mainly servicing the lower and mid-mountain areas. This means fewer runs are accessible but those that are open are well-maintained.
Weather-wise, expect crisp cold conditions with mountain summit temperatures fluctuating between approximately -8°C to -4°C and base temperatures sitting a bit warmer, around -3°C to 6°C. The next few days forecast predominantly cold but relatively dry weather with sporadic light snow flurries (less than 1 cm expected over the next few days), accompanied by partly cloudy skies. Temperatures will range broadly, from chilly lows below freezing at night to daytime highs nudging above freezing up at the base. The freeze-thaw cycle is underway, which is typical for this time of year, so the snow surface can be firm or crusty in places, especially on sunny slopes.
While the extensive off-piste terrain waits for a deeper snowpack, the open groomed runs offer good conditions now, with snow described as "gripping"—a sign of solid packed snow that lends good edge control for sharp turns. The valley run is available, but major snow parks like the fun park and halfpipe are not yet open, and night skiing isn't available just yet.
Looking at the seasonal totals, Big Sky gets an average of **248 inches (over 630 cm) of snow annually** with about 66 snowfall days per season, so the current snowpack is just the beginning of what promises to be a full and rewarding winter. Current observations and winter outlooks from local experts and the Farmer’s Almanac suggest a "mild wet" winter pattern for 2025-26, which means slightly warmer temperatures but more moisture in the air—good news for heavier, sometimes wetter but potentially deeper snowfalls mid-season. Historical data and forecasts also indicate that Big Sky tends to maintain consistent cold high-alpine conditions, which should help preserve snow quality once the major snowstorms arrive.
The next five days will see minimal additional snowfall (generally less than 1 inch), coupled with temperatures that can warm up over 40°F (around 5°C) during the day at lower elevations but remain firmly below freezing higher up, preserving the snowpack. The forecast calls mainly for intermittent clouds, occasional sunshine, and light snow showers later in the week, perfect conditions for enjoying those early season groomers without the crowds.
Visitors planning a trip should note that some amenities like snow parks and night skiing are still closed. It’s wise to prepare for variable conditions especially with some freeze-thaw cycling causing firm snow surfaces during the day and possible icy patches in shaded areas. Dress in layers, and anticipate mostly bluebird powder days tempered by firm base conditions.
So for skiers and snowboarders eager to "think like a local," Big Sky in early December 2025 offers a promising early season with stable snow depths, good grooming, and manageable lift access. Expect crisp mountain air, mostly clear skies, and solid snow conditions to ease you into the season, with much more terrain opening as December rolls on and the storms start to pack in more powder. It’s a classic start to Montana’s iconic winter playground—cold, crisp, and ready to reward early risers and powder hunters in the days ahead.
