July 16, 2018 Surf Forecast
Swell Summary
Outlook through Monday July 23: Fresh to locally strong trade winds will continue to produce rough and choppy surf along east facing shores for the next few days. A boost in the trades will come around Wednesday as a low pressure area passes to the south of the islands. This will cause a bump up in the surf along the east facing shores to near advisory level. A long period southwest swell will diminish slowly through tonight. The next significant bump- up from the south is slated for Wednesday night, with a 2 foot 18 second period swell. A slightly longer period 2 foot south swell is due in over the upcoming weekend, resulting in near advisory level surf for the south 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.
