@korina I could change the layer to "waves" but the forecast (chart at the bottom) doesn't have the "waves" ("Wellen" "Dünung" and "Seegangszeit") included. Is there a parameter which can be changed to see it?

@korina I found your widget (https://www.windy.com/de/-Widget-auf-Seite-einbetten/widgets?45.077,-1.121,7) and saw that the weather forecast for wind can be included. Is it possible to not only show the wave layer but also the wave forecast?
