• When I check the NOAA swell/weather reports it states one thing. I open the Windy app and drop a pin to get accurate swell/weather reports for the route that I want to take, and the information I am receiving is conflicting. How accurate is the windy swell reports?

    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 :)

    In addition the NOAA use probably their WW3 wave model.
    Which model do you use on Windy? If you use the default wave model i.e. ECMWF WAM, the wave forecast can be different.
    At least be sure to use the same data source, WW3 being available here too.
