Frequently Asked Questions
How accurate are the ski snow forecasts?
We cross-reference two leading weather models — GFS (Global Forecast System by NOAA) and ECMWF (European Centre for Medium-Range Weather Forecasts) — to provide a confidence-rated snow forecast for each resort. When both models agree, confidence is high. The 7-day forecast is the most reliable; accuracy decreases for longer ranges.
How many ski resorts are covered?
We cover 60+ major ski resorts across 22 countries on 5 continents, including top destinations in the USA, Canada, France, Switzerland, Austria, Japan, Chile, Argentina, Australia, New Zealand, and more. We continuously add new resorts.
How often are snow forecasts updated?
Forecasts are fetched in real-time from Open-Meteo's GFS and ECMWF models each time you visit or click Refresh. The GFS model updates every 6 hours and ECMWF every 12 hours, providing the most current data available.
Can I check snow conditions for Southern Hemisphere ski resorts?
Yes! We include ski resorts in Chile, Argentina, Australia, and New Zealand, which have their ski season during June to October. Snow forecasts are available year-round for all resorts regardless of hemisphere.
What do the confidence ratings mean?
We compare snowfall predictions from GFS and ECMWF models. High confidence means both models predict similar snowfall. Medium means they're close but differ somewhat. Low confidence means the models disagree significantly, so conditions are more uncertain.
Which are the best months for skiing in each hemisphere?
Northern Hemisphere (USA, Canada, Europe, Japan): December through April. Southern Hemisphere (Chile, Argentina, Australia, NZ): June through October. Some high-altitude glaciers like Zermatt and Les Deux Alpes offer summer skiing year-round.
