Swell Summary
A series of long-period south swells will spread up across the area into next week, which will keep surf near or above the summertime average along south facing shores. The latest guidance indicates that surf along south facing shores should gradually increase into early next week, and surf heights will likely peak near the High Surf Advisory threshold along south facing shores from late Saturday into Monday. Surf is then expected to gradually lower along along south facing shores from late Monday into the middle of next week. Surf along north facing shores will remain very small through this weekend. A series of small northwest swells will likely provide a small boost to surf heights along most north and west facing shores from Sunday night through the middle of next week. Finally, the weaker trade wind regime will cause surf heights to remain slightly below seasonal values along east facing shores through the middle of next week.
