# Global Ski Forecast

> Global Ski Forecast (https://globalskiforecast.com) publishes free 16-day snow forecasts for 188 ski resorts in 38 countries across 6 continents. Every forecast is a weighted consensus of 4 weather models — GFS (NOAA), ECMWF, ICON (DWD) and GEM (CMC) — blended with regional weighting (e.g. ICON is favoured in the Alps, GEM in North America). Data refreshes every 3 hours. The JSON API is free and requires no key. A remote MCP server is available for AI agents.
