A Surf Advisory is in effect from now through noon on Thanksgiving Day. Large northwest swells are expected, as are long period forerunners, that could cause sneaker waves and stronger rip currents. Swell heights are expected to be 14 to 16 feet at 16 to 19 second intervals tomorrow increasing to 18 to 24 foot waves on thanksgiving morning. The large swell is also expected to continue the coastal erosion that began this past summer.
