OpenSnow

Get the most accurate snow forecast and mountain weather intelligence with OpenSnow, the trusted app for skiers, snowboarders, and winter enthusiasts worldwide.

Mountain weather demands precision. Standard forecasts miss critical details about snow accumulation, storm timing, and dangerous conditions unique to alpine terrain. OpenSnow cuts through the noise with expert analysis, real-time data, and proprietary AI-powered forecasting built specifically for mountains. Whether you're planning your next run or tracking severe weather, you'll make better decisions faster.

View a complete 15-day snow forecast in seconds, including hourly breakdowns, snow depth maps, and historical snowfall patterns. Instead of drowning in raw weather data, read daily expert forecasts written by local meteorologists across the US, Canada, Europe, Australia, and New Zealand. These specialists know their regions intimately and deliver actionable insights you won't find elsewhere.

OpenSnow's advanced mapping tools let you track incoming storms with super-resolution radar, precipitation forecasts, and 3D visualization of snow depth and avalanche risk. Monitor air quality, wildfire smoke, and active fire perimeters—all on offline maps you can download and access anywhere. Track lightning risk, hail, damaging winds, and tornado potential with real-time severe weather alerts powered by StormNet, our breakthrough storm forecasting system.

Behind the scenes, PEAKS—our proprietary mountain weather engine—delivers forecasts up to 50% more accurate in rugged terrain than standard models. Combined with StormNet's multi-component AI analysis, you're getting a fully operational weather intelligence system purpose-built for mountains, not generic flatland forecasting.
