Wind colors for sailors ... and for everyone.


  • Sailor

    The color palette used for the wind layer can be optimized for navigation at sea.
    Most sailors know and use the Beaufort scale. Each degree of this scale corresponds to a range of wind and to a sea state. Therefore it is useful to calibrate the wind color settings according to the Beaufort scale. In this way, at a glance, it is possible to know which are the areas concerned by a certain wind force.
    These settings are based on the following considerations:

    • Light winds are displayed by light colors while strong winds are shown by denser, darker colors for an intuitive approach. However beyond 64 kt i.e. 12 Bf or Hurricane force, rather than being darker, the colors become very bright « like LED lights ».
    • Each wind range is represented by a uniform color without shading or smoothing, with only a small mixing transition.
    • From 64 kt, colors are chosen according to degrees used by NHC (Cat.1, Cat.2...)
    • Choice of colors has been mainly based on
      BLUE when conditions are too light or just enough to use sails (0Bf - 3Bf)
      GREEN when conditions are the best for sailing (4Bf - 5 Bf),
      ORANGE when conditions become tougher (6Bf),
      RED when a coastal cruising sailboat must find a shelter (7Bf - 8Bf).

    HOW TO APPLY THESE COLORS

    You must be logged in to apply these settings in your Windy cloud. Then these settings will be applied to all your devices.

    In the Menu (hamburger icon)
    Go to Settings
    Choose Customize color scale
    Select overlay: Wind
    At bottom of page find the line Import/export
    Click on [view code] to open a window pop up
    Delete the text code in this window
    Select and copy all lines of code here below and paste them in the window
    Then press [Import Gradient]
    Press Save

    [68.93,[0,256,256,256]],
    [69.44,[256,37,256,256]]]

    Try to use these new colors during at least one week. If you like them, keep them. If you don’t like, you can come back to the default Windy settings by pressing Load defaults

    If you keep them, you can use the wind speed units that you like ...kt...km/h...mph...m/s

    You may try it. Personally I’m not convinced that sailors are so familiar with these standardised colours.
    I started with the following choice of colours:
    Green: the best conditions for sailing. Enjoy wind and sea.
    Orange: conditions becoming tougher. Be careful
    Red: hard conditions for a standard 30’ - 40’ cruising boat. Better to stay sheldered.
    The result is may be not artistic but efficient.
    I like to explain the Beaufort scale also with this table from F.Singleton, with a little humour :
