@daniele93 Thank you for your link. Apparently LaMMA uses the WWW3 model from the NOAA to forecast waves field in Mediterranean Sea. Windy does not run any weather models but visualize data received from numerical prediction centers like NOAA, ECMWF.... So the question is....does LaMMA provide free data from this model? And would Windy accept a new data source? Then for which reason do you prefer WWW3?
