What is the difference between the three swell maps?

The seastate that you can observe in a given place, is a mix of different type of waves:

• The windsea (also called wind waves) is produced by the local wind.

• The main swell is produced by a strong wind in a remote place. The swell travels great distances to where you observe it.

• Secondary swells are produced also by winds in other remote places.

All of them have different heights, come from different directions and show different periods (i.e. the time between 2 wave crests)
Swell 1 is the main swell,
Swell 2 and 3 are secondary swells
The swell classification 1, 2, 3 depends on their respective heights

You find this detail on Windy by pressing the yellow arrow on the picker.
