Swell Summary
Surf along south facing shores will remain up through early next week due to overlapping, long-period south-southwest swells. Heights will remain at the advisory level today, then briefly dip and hold just below this level Sunday through Tuesday as the next pulse fills in and peaks. A downward trend is expected Tuesday through midweek. Surf along north facing shores will steadily lower through the weekend, with a return to a more typical pattern for this time of year next week. Surf along east facing shores will remain well below average through the weekend. An upward trend is expected next week as the trades return locally and far upstream over the eastern Pacific.
