        @meridies Indeed, this is listed in the Description of Weather Overlays post, but maybe one detail could be clarified.

        Waves is described as:

        Waves: Significant wave height and its period of all wave types combined (swell and wind waves). Close to the shoreline, the actual height is influenced by the shape of the sea bottom.
        

        It would be useful to know how the math used to combine "significant wave height and period its period" from wind and several different sources of swell. The resulting calculation could be very misleading and, in fact, an inspection of these values in Windy is confusing.

        For example, as I inspect a point now, I see wind waves listed as 1.0 m, swell 1 at 0.6m and swell 2 at 0.7 m. But the total "wind" value provided in the annotation within the map is 1.2 m. How this is arrived at is unclear.

          This thread may answer your first question:
          https://community.windy.com/topic/3603/different-definitions-for-the-wave-periods-are-shown
          And this article too:
          https://confluence.ecmwf.int/plugins/servlet/mobile?contentId=131397261#content/view/131397261

          Concerning your example, what do you mean with ‘the total "wind" value’ ?
          If you mean the Wave overlay, it corresponds effectively to the ‘total sea’:

            Would it be possible to have these kind of information in an ad hoc page? Even better if it's shown as a detail when selecting an overlay.

                  setting temperature off in menu but not clearing. Location set and is marked, goes there when pressed from upper left button, but misadjusts so unknown way especially when pulling day states. Goes to an unselected location.
                  thx
