@idefix37 Thank you!

My question is about the wave height forecast.
Wave height is defined as the difference between the highest and lowest point in a wave (crest to trough). Although the label in windy says the forecast there is for wave height, everyone I have spoken to, including experienced professionals, has told me the number written there is in reality the wave amplitude, so from the crest to the "middle" of the wave, or the line of a perfectly calm sea - so you would need to multiply that number by 2 to get a more accurate representation of the actual wave height.
Is this correct, can someone please clarify, as I want to be sure about this!
