<![CDATA[Waves]]>Hey
We are currently extremely depending on waves on our job. We have a limit on 1,5 meters significant.
The values shown in the app or webpage is it maximum, average or significant waves?

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.

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 :

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".

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.

Significant wave height
i.e. the mean wave height (trough to crest) of the highest third of the waves.
