Swell Summary
Surf along south facing shores will hold near the summer average through Saturday with a steady decline expected Sunday into Monday. Surf heights will return to background levels by early next week along south facing shores.
Surf along north facing shores will see a small, short period swell expected to arrive late this weekend. This swell will be overshadowed by longer period energy out of the northwest starting Monday night of next week. This swell should peak on Tuesday and could produce surf heights near the September average of 4 to 6 feet. Another reinforcing pulse out of the north is expected around the same time the northwest swell arrives. A mix of north and northwest swells are expected next Tuesday through Thursday.
Below average surf is expected to continue along east facing shores due to gentle to moderate trade winds persisting through early next week.
