      Hi. Will you be so kind to add 65 m altitude to the scale, please. There are a lot of wind turbines with the same high of hub. So it will be very convinient to understand a wind speen at this high. And one more thing. When I change the altitude in scale the forecast changes only for present time. Please, make some chanches in the program in order to change the forecast with the altitude changing in the scale. Thx.

        You know that Windy visualises weather models data. I don’t think that weather models provide wind speed at 65m height. They show generally 10m and 100m.
        In your case I would consider wind at 100m with a reduction factor depending on the roughness of the ground below and surrounding it (open fields, woods, hilly or flat land, sea...)

          Models used by Windy provide forecasts for much more vertical levels than available on UI level scale.
          E.g. GFS 0.25 provides values of u/v wind components at [10, 20, 50, 80, 100, ...] meters above ground (48 vertical levels in all for wind); I'm not sure all of them would be of a general interest, thus I guess Windy made a selection of levels on UI.

          About the remark "When I change the altitude in scale the forecast changes only for present time.": nope, currently selected level un UI correctly follows all available forecasts (even on animations).

          ¯\_(ツ)_/¯
