Swell Summary

Outlook through Saturday August 11: Small south swells will maintain background surf along south facing shores through the weekend. A slightly larger long-period south swell arriving Monday is expected to increase surf to near the summertime average along south facing shores early next week. Strong trades will produce elevated rough surf along east facing shores today. Surf along these shores is expected to lower from Sunday into early next week as the trades weaken slightly. Note, that depending on the future track and intensity of Hurricane Hector currently in the East Pacific, surf may increase across some shorelines starting around the middle of 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.
