April 23, 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 Sunday April 29: A moderate northwest swell expected to build this evening into Monday will fade Tuesday through midweek, which will lead to surf lowering along north and west facing shores. Surf along east facing shores will remain rough through the week and may reach advisory levels by midweek. Another moderate northwest swell is expected Thursday through Saturday, which will lead to rising surf along north and west facing shores. A reinforcing southwest swell expected early in the week will continue to generate small to moderate surf along south facing shores each day through midweek before fading.
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.
