Swell Summary

Outlook through Wednesday June 06: The current southwest swell will continue to build through Thursday, then gradually ease Friday and Saturday before a larger south- southwest swell arrives late Sunday. This swell may cause surf to reach the High Surf Advisory criteria along south facing shores early next week. Rough surf will increase along east facing shores over the next couple of days due to strengthening trades, then trend down this weekend as the trades weaken. Tiny background surf will persist along north facing shores through this weekend.
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.
