Swell Summary
Outlook through Wednesday April 18: A moderate northwest swell will peak Thursday evening then decline. A large northwest swell will gradually fill in on Friday, peak Friday night through Saturday morning well above advisory levels, then steadily lower Saturday night and Sunday. A series of small, mainly background south to southwest swells are expected through the week, with a slightly larger pulse possible on Monday. As trade winds strengthen this weekend, rough east shore will reach advisory levels and remain elevated into early 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.
