Snow & Weather Conditions
We use 10 years of historical data to help you plan — not a live snow report.
Swiss resorts benefit from high-altitude glacier terrain and reliable snowfall. The combination of altitude and north-facing slopes preserves snow quality throughout the season. A lofty position in the mountains translates to reliable subzero conditions for much of winter. This altitude sweet-spot catches the brunt of incoming weather systems while keeping the base firm and well-preserved. Season-long totals generally land between 6 and 10 metres, translating to a robust mid-winter base well above 2 metres.
Best Time to Ski
The best time to ski at St. Moritz is November and April, with 69.3cm average snowfall and 40% powder probability. Based on 10 years of historical snowfall data from PowderDays. Season runs from late November to late April, with glacier skiing extending into summer. February and March are peak months for fresh snow.

What Makes It Special
Dramatic glacier descents, perfectly groomed trails, and challenging off-piste routes amid some of the most photogenic mountain scenery on earth. Many Swiss resorts offer year-round glacier skiing. Swiss precision meets mountain tradition — expect immaculately groomed pistes, panoramic mountain restaurants, fondue, and a sophisticated yet welcoming atmosphere.
Switzerland pioneered mountain tourism in the 19th century. St. Moritz hosted the Winter Olympics twice (1928 and 1948) and is credited with inventing winter alpine tourism when hotelier Johannes Badrutt wagered with British summer guests in 1864 that they would enjoy the Engadin in winter. Zermatt offers the highest lift-served skiing in Europe at 3,883 metres.
Data Sources & Methodology
All snowfall statistics for St. Moritz 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 St. Moritz's coordinates (46.49, 9.84) and 3,303m 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.
