      It used to be easy to switch between the ECMWF and GFS models. Now I am stuck with the ECMWF model.

      The ECMWF model greatly underestimates the swell period. Take for instance Cape Town for tomorrow. GFS shows a 15 sec swell, ECMWF shows an 8 sec swell.

      The new menu also omitted the swell period chart?

        Hi Piet, the GFS model is possible to change on the right side, just above the scale.

          @TomSlavkovsky . When I look at the wind map, I can change to GFS model. When I then switch to the wave map, it changes to ECMWF, and the GFS option disappears? Also, there is no wave period map anymore?

              You are right; it has not been prepared yet for the new version of Windytv. It should be added by the end of this month. Sorry about that.

                Waves are provided by ECMW only. Perod map nobody used so we put it down. We can get it back.

                  Every surfer I know uses the GFS wave period model, I see no use for Windytv without that feature.

                      @ivo You must put GFS wave model back. Every surfer only uses GFS as @tubevertigo correctly stated. ECMW gets the wave period completely wrong. For surf forecasting, the wave period is of critical importance. The GFS wave period map needs to be brought back. This is one of the few maps though where windytv is not as good as others, so it is worthwhile looking at wave period maps from other providers eg. buoyweather, noaa, etc.

                            For ECMWF the mean wave period is shown but for WW3, the peak wave period.

                            These are 2 different quantities when the sea state is multi model (different wave systems)
