Offshore NDBC buoys are hovering around 16 feet 16 seconds largely due to a large north- northwest swell (340-350 degrees) that is moving through the island chain. This swell is expected to decline tonight as a large, long- period northwest (310 deg) swell fills in from the northwest through Wednesday, keeping surf elevated along north and west facing shores. This swell will increase further late Wednesday, leading to warning- level surf for exposed north and west facing shores through Thursday. A gradual downtrend is expected Thursday night through Friday, with heights dipping back below advisory levels on Friday. For the upcoming weekend, guidance shows a large, long- period west- northwest (300 deg) swell filling in Saturday, peaking Saturday night into Sunday before slowly trending down into early next week.
Surf along east facing shores will remain small due to the lack of trades locally and upstream of the state. The exception will be a rise in surf for shores exposed to the large northerly swells. Surf along south facing shores will come up late tonight through midweek due to a mix of fresh to strong south-southwesterly winds locally and a small, long-period south swell. A downward trend is expected through the second half of the week.
