DWD ICON Global

The ICON (Icosahedral Nonhydrostatic) model is a numerical weather prediction model developed by the German Weather Service (Deutscher Wetterdienst, DWD).

Live Forecast Data

  • Global coverage at 13 km resolution (1440x2880 grid)

  • Four daily runs (00, 06, 12, 18 UTC)

  • 00/12 UTC runs: 180h forecast (7.5 days); 06/18 UTC runs: 120h forecast (5 days)

  • Hourly up to 78h, then 3-hourly

  • Real-time data access via Python SDK or REST API
