      The Swell2 arrow does not always show zero.
      Here it shows 0.4m:

      @afurley
      All waves models don’t take into account the effect of current.

      For WAM model from ECMWF(July 2018):
      « Considerations when using output from ECWAM
      Not yet modelled are the interaction of waves with sea-surface currents. In particular areas, (e.g. Gulf Stream or Agulhas current), the current effect may give rise to localised changes of up to a metre in the wave height »
      From
      https://confluence.ecmwf.int/plugins/servlet/mobile?contentId=131397261#content/view/131397261

      For WWW3 model it seems to be different (March 2019):
      https://github.com/NOAA-EMC/WW3/wiki/Manual
      Page 1
      « The model [....] computes other transformation processes such as the effects of surface currents to wind and wave fields, and sub-grid blocking due to unresolved islands »
      Page 163
      « 3.9 Winds and currents
      Model input mainly consists of wind and current fields. Within the model, winds and currents are updated at every time step ∆tg and represent values at the end of the time step considered. »

      In any case it would be much better for you to sail downwind and down swell. But this is quite tricky in the Agulhas current area, the swell being mostly from SW. Don’t you plan a stop in Durban?

      I agree this would be helpful for fishing as well. Thanks

      So, this is Windy android app version 14.4.2 .................... And this is windy.com version 14.8.0 .................... At almost the same location and time.

      ...

      Hope it helps.

      All the best!

      @tubbssurf ECMWF-WAM and WW3. We use both and you can choose
