Swell Summary
Outlook through Tuesday August 07: Strengthening trades will bring an increase in wind swell today through Thursday along east facing shores. The wind swell is expected to peak Wednesday night and gradually decline through rest of the week. A small south swell is expected to arrive later today followed by another small one on Thursday. These swells will help maintain background surf along south facing shores through the week and will decline over the weekend. For north facing shores, a small and short- lived north-northwest swell is expected to arrive on Wednesday. Looking out to next week, a slightly larger south to south-southeast swell is possible late Monday into Tuesday and may bring surf near the summer average. Otherwise, no significant swells are expected.
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.
