September 21, 2018 Surf Forecast
Swell Summary
Outlook through Friday September 28: Surf will remain below advisory levels along all shores through the middle of next week. The current south swell will continue to slowly decline through Saturday. Rough, short-period surf will remain around the summer average along east facing shores through tonight, then decline during the weekend. The first large northwest swell of the season could arrive late next week, possibly reaching advisory levels along north and west facing shores.
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.
