      I live in El Salvador. The ocean entrance into our port is over an often breaking sandbar. For ten years, I used the detailed wave forecast on Buoyweather to inform boaters if it is safe to cross the sandbar. but, BW is eliminating that feature. I am struggling with the Windy wave feature because it is in whole feet increments. For example, the bar may be safe with a swell of, 5.2 feet but not 5.9 feet. I've tried working with the color scale but, it is impossible to judge color gradients to discern an useable measurement.
      I believe there must be some numerical data associated with the color scale that might be extracted by Windy engineers.
      This is a very worrisome situation for me because it involves the safety of boats and their passengers.
      Does anyone else use wave data comparable to my needs?

        Color scale for wave / swell is customisable.

        https://community.windy.com/topic/10336/customize-the-color-scales-of-windy-layers?_=1667162346374

        This article should enable you to apply special colors for the 2 thresholds you mentioned.
        If you need any further help, I can make a color scale suggestion to suit your need.

          @idefix37 I have customized the colors but it is impossible to judge color gradients to discern an useable measurement.

            @idefix37 also, Windy will not let me change the steps, for example it will not allow 4.5 feet, it switches back to 4

              There is a way to display non-smoothed colors:

              49E13DDC-AA85-4CE9-8B25-8C656E4FEFB1.jpeg

              This scale uses 2 threshold, 5.3ft=1.61m and 5.9ft=1.80m. Using meters instead of feet avoid rounding values
              Color scale is based on :
              Blue below 5.2ft
              Orange between 5.3ft and 5.9ft
              Red above 6.0ft

              If you want the code of this scale, let me know.

                IT IS IMPORTANT TO NOTE THAT WAVE AND SWELL FORECASTS CAN BE INACCURATE, ESPECIALLY NEAR THE SHORELINE WHERE THE SEABED IS LOCALLY SHALLOW.
                UNDER THESE CONDITIONS, THE HEIGHT OF WAVES CAN BE CONSIDERABLY INCREASED.
                Reported data by buoys are more accurate.

                  @idefix37 please send me code for the scale. Also, what increments can I put in the wave height scale. Now, when I try incremental feet it reverts to whole feet.

                    Here is the code:

                    [[0,[159,185,191,255]],
                    [0.5,[48,157,185,255]],
                    [1,[56,104,191,255]],
                    [1.6,[86,90,197,256]],
                    [1.61,[231,132,35,256]],
                    [1.80,[231,132,35,256]],
                    [1.81,[200,66,13,256]],
                    [2.40,[200,66,13,256]],
                    [2.50,[215,0,50,256]],
                    [5,[175,80,136,255]],
                    [10,[175,80,136,255]],
                    [17,[154,48,151,255]]]

                    I guess you know how to use it. But if necessary here are the main steps:
                    In windy.com Menu (not in the phone app) go to Settings
                    Scroll down and choose Customize color scale
                    In Select overlay: Choose Waves
                    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
                    Press [Import]
                    Press Save

                    These new colors will be saved in your Windy cloud and be applied to all your devices including in phone app.
                    But if you want to come back to Windy default colors you can press Load default

                    To you remark ‘ Now, when I try incremental feet it reverts to whole feet’, I would recommend to use meters instead of feet as feet are automatically rounded by Windy.
                    Then using this color scale, you know that the orange color means wave between 5.3ft to 5.9ft and red more than 5.9ft. That should meet your requirements?
