Swell Summary

Outlook through Friday October 05: Rough surf along east facing shores will gradually increase this weekend as the trade winds strengthen. Surf will rise along north facing shores today and peak on Friday night out of the north- northwest direction. This swell is expected hold through Saturday and taper off Sunday into early next week. A larger reinforcement out of the northwest is expected to fill in Monday night. A small southwest swell will produce a small 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.
