Swell Summary
Outlook through Thursday October 04: Rough surf along east facing shores will gradually increase from Friday through this weekend as the trade winds strengthen. A north- northwest swell arriving tonight will produce moderate surf along north and west facing shores from Friday through this weekend. A small to moderate southwest swell arriving today will produce a noticeable boost in surf heights along south facing shores from Friday into early next week. A slightly larger reinforcing south-southwest swell is expected to fill in next Tuesday.
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.
