Swell Summary
Outlook through Saturday April 28: A moderate northwest swell will build Sunday and peak Sunday night but will remain below advisory levels along north and west facing shores. Another moderate northwest swell is possible next Thursday. Generally small to moderate surf is expected along south facing shores through next week. Rough surf will persist along east facing shores due to the trade winds, and build to near advisory levels during the first half of next week as winds strengthen.
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.
