April 25, 2018 Surf Forecast
Outlook through Tuesday May 1: A moderate, long-period north-northwest swell is expected to arrive Thursday and peak Friday, with surf heights remaining below advisory levels. A larger north-northwest swell is possible this weekend and early next week, with the potential for advisory-level surf along north and west facing shores. Rough and choppy surf along east facing shores will persist through Wednesday, then diminish Thursday and Friday as trade winds weaken. Small swells from the south will persist for most of the week, producing small surf along 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.
