April 07, 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 Friday April 13: A new northwest swell will gradually fill in tonight, peak on Saturday, then lower gradually on Sunday. A larger northwest swell is expected to arrive Sunday night. This swell will exceed advisory levels and could reach low end warning levels for a brief time during the peak of the swell late Monday and Monday night. This swell will lower gradually Tuesday and Wednesday. Another smaller northwest swell is expected around Thursday. Strengthening trade winds will cause for a bit of an increase in short period choppy surf along east facing shores. There will also be a series of small, mainly background southerly swells this weekend and on 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.
