Swell Summary
Outlook through Saturday July 28: Forerunners from a new long period south swell are expected to begin filling in late this afternoon with the swell peaking on Sunday. A High Surf Advisory is now in effect from tonight through Monday for all south facing shores. This swell will fade during the first half of next week. No other significant swells are expected for next week.
Surf heights are forecast heights of the face, or front, of waves. The surf forecast is based on the significant wave height, the average height of the one third largest waves, at the locations of the largest breakers. Some waves may be more than twice as high as the significant wave height. Expect to encounter rip currents in or near any surf zone.
