Windy does not create any forecast data but instead only visualises forecast and actual data received from various third parties, including the world's major weather forecast model providers such as ECMWF (European Centre for Medium-Range Weather Forecasts), GFS (NOAA), NEMS (MeteoBlue), Icon (DWD), etc.

Windy therefore has no control over the forecast or actual data provided and issues regarding accuracy should instead be addressed to the relevant forecast model provider - links to their websites are available on the forecast information pop up window.

Thank you for your understanding :)
