July 19, 2018 Surf Forecast
Swell Summary
Outlook through Thursday July 26: Surf along east facing shores will continue to gradually subside today, and will return to normal summer heights by Friday. A series of reinforcing south and southwest swells will maintain small to moderate surf along south facing shores through Friday. Slightly larger and longer period south- southwest swells may cause surf to approach the High Surf Advisory threshold along south facing shores from Saturday into Monday. This longer period south swell is expected to fill in on Saturday, peak Sunday and gradually decrease Monday through the middle of next week.
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.
