Snow & Weather Conditions
We use 10 years of historical data to help you plan — not a live snow report.
Colorado is famous for light, dry "champagne powder" produced by its continental climate and high altitude. Over 300 days of sunshine a year mean that fresh snow is often followed by bluebird skies — ideal conditions for powder skiing. The rarefied atmosphere at this elevation keeps ambient temperatures far below the freezing mark for months on end, ensuring a stable base that just keeps growing. Even modest weather disturbances tend to deposit surprisingly fine, low-moisture crystals. Cumulative seasonal totals routinely top 8-12 metres, packing down into a base layer 3-4 metres deep by mid-winter.
Best Time to Ski
The best time to ski at Aspen Snowmass is February and March, with 45cm average snowfall and 25% powder probability. Based on 10 years of historical snowfall data from PowderDays. The ski season typically runs from mid-November through mid-April, with March often delivering the deepest snowpack.

Data Sources & Methodology
All snowfall statistics for Aspen Snowmass are based on 10 years of historical data (2015-2025) from the Open-Meteo Historical Weather API, which provides ERA5 reanalysis data from the European Centre for Medium-Range Weather Forecasts (ECMWF). Daily snowfall totals are queried at Aspen Snowmass's coordinates (39.19, -106.82) and 3,813m elevation, then aggregated into monthly averages, record highs/lows, and powder probability scores. Powder probability represents the chance of receiving 15cm or more of fresh snow in any given week during that month.
