Swell Summary
Outlook through Monday September 24: The small northwest swell will peak today, then gradually subside through Wednesday. Trade winds will maintain choppy surf along east facing shores through today. The surf along east facing shores will subside through midweek, then build again as stronger trade winds return. A south swell is expected to fill in on Tuesday, peak early Wednesday near the summer average, then decrease through Friday.
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.
