Waves

@ivo
I think you have to change the definition, here:
https://community.windy.com/topic/3361/description-of-weather-overlays/1

Is significant wave height, not mean wave height.

Confirm that "Waves" mean Significant wave height. Description corrected.

I think it is necessary to correct this definition of "mean waves heght" here too:

@giodolif Hello, significant wave height is also defined as "mean wave height" - https://en.wikipedia.org/wiki/Significant_wave_height

[giodolif]

@korina thank you for your quick reply. Windy.com is an amazing tool for many many users from a wide range of uses. So that I think it is worthy to be accurate on using technical words. Note that, the "significant height" is the same as "mean wave height of the highest third of the waves". If you don´t want to use "significant wave height", it is not correct to substitute it just with "mean wave height". The true "mean wave height" is actually around 64% of the "significant height".

.

Best wishes.

@giodolif I will correct the description to "Significant wave height". Thank you for inputs.

This graph is a bit confusing: Significant waveheight is the average of 1/3 of the highest waves.
thus e.g. 100 waves divided from small to largest: the average of waves 67 to 100 is the significant waveheight :

@wmassaar

The graph shown by @giodolif doesn't say anything different from what you are saying.
It is a statistical distribution of the wave heights. On the y-axis it is the number of waves not their height.

The values shown on the app or website are typically the significant wave height, which represents the average height of the highest third of the waves.
