Swell Summary
Elevated surf will continue along north facing shores due to a short- to medium- period north swell. This swell will quickly be overshadowed by longer- period energy out of the northwest starting tonight. The northwest swell will peak Tuesday afternoon. A reinforcing pulse out of the north should arrive around the same time the northwest swell arrives. A mix of north and northwest swells are expected to continue thereafter, keeping north shore surf elevated, but slowly declining, through Thursday. Surf along south facing shores will continue to decline through today as the south swell fades, despite a slight boost from short period southeast energy. Below average surf is expected to continue along east facing shores persisting through early next week.
