Chart help
Swell period roughly translates to the energy of waves you see, and will indicate whether the swell is a solid ground swell or shorter wind blown waves. The best way to make a decision on this information is to take a look at this overall swell period forecast in combination with the swell height forecast charts and then view the swell details at the individual beach.
