Swell maps



  • 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 amber arrow on the picker.
