July 18, 2018 Surf Forecast
Swell Summary
Outlook through Wednesday July 25: With rough, and rising, surf caused by strengthening trade winds, a High Surf Advisory has been issued for east facing shores through tonight. Surf along these shores is expected to gradually lower Thursday through this weekend as the trade winds weaken. 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 along south facing shores from Saturday into Monday.
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.
