July 04, 2018 Surf Forecast
Our weather team will bring you any urgent weather alerts or updates as they occur. Check our breaking news section for the latest.
Outlook through Tuesday July 10: The current S swell will gradually decrease tonight into Wednesday. The next S swell is expected to begin filling in on Thursday and peak on Friday. With peak swell heights near 3 feet, surf along S facing shores is expected to approach but remain below advisory levels. Strengthening trade winds will cause a gradual increase in short period choppy surf along east facing shores. This combined with a longer period east swell from distant Tropical Cyclone Fabio in the Eastern Pacific may cause surf to reach High Surf Advisory levels on east facing shores later this week and into the weekend.
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.
