Hi:
The problem, as Idefix comments, is the Spanish translation.
Wave in English are "waves generated by the wind", while waves produced in distant areas from storms are called swell.
In Spanish when there are waves of wind we say "Mar de viento".
To the so-called swell "Mar de fondo o tendida".
In Windy there are 3 types of "Mares de fondo", one main and 2 secondary.
The combined waves and wind waves also mark us.
Understood and thank you very much.
I am attaching what would be a more correct translation into Spanish.
