And here´s a custom one I made for myself with the same colors, but differently scaled as so to differentiate multiples of my "head high" tresholds (I am 1.7m of height):
At my 1.7m "Head High" treshold the color switches from blue to green.
At my 3.4m "Double Overhead" treshold the color switches from green to yellow.
At my 5.1m "Triple Overhead" treshold the color switches from yellow to orange.
At my 6.8m "XXL" treshold the color switches from orange to red.
I know this is not perfect since a small long period ground swell can produce overhead waves, but until Windy gives us "Surf", "Energy" or even just "Period" sea maps, this is the next best thing 😛 enjoy:
