Swell Summary
Surf along east facing shores will remain elevated with choppy conditions into the weekend due to the fresh to strong trades. Select areas on the south and north shores should see some localized increases in surf due to trade wind swell wrap. No swell from west or north directions are expected over the next seven days, thus surf heights for north and west facing shores will remain nearly flat.
