      Dear support,

      I have found a little bug in wind direction prediction accurancy indicator.
      When predicted and measured direction differs at 3 degree, it should still be green.
      I think there is a mistake where Windy assumes 358 - 1 = 357 and not a shorter path.

        You are surely right, as shown by another example:

        F5F9CC48-9D89-4779-9173-70C340B44EBD.jpeg

        0° is exactly the same as 360°, but it is considered here as a bad matching between reported and forecast wind direction. There are not 360° between these 2 values and the indicator should be bright green ! :-)

            Maybe it should be also taken into account that anemometer wind direction values for WMO/ICAO stations in METAR/SYNOP/TEMP messages are rounded to 10° (i.e. 0°, 10°, 20°, ...340°, 350°), while models and AWS stations provide values rounded at 1°.

            ¯\_(ツ)_/¯
