Swell Summary
The current south swell will hold today than steadily decline Sunday. A series of small, medium period swells will persist through the weekend keeping south facing shores from going flat. Small, short- period north swell will continue into the weekend. A larger moderate medium period north swell reinforcement will arrive late tonight. A rise in surf overnight is expected but the north swell looks to peak Sunday well below High Surf Advisory levels. Surf along east facing shores will remain small but can expect a slight increase early next week as the trades strengthen.
