Swell Summary
The breezy trades will maintain rough, choppy surf along the east-facing shores. A longer period NE swell (around 10 seconds), associated with former Tropical Cyclone Irwin, is also mixed in. However, peak east shore surf should remain below the 10 ft High Surf Advisory (HSA) threshold. East shore surf is expected to trend lower on Sunday and into early next week as the trades weaken.
South shore surf should remain small through the remainder of this weekend. A moderate south to south-southwest swell is expected to slowly fill in Monday and peak from Tuesday through Wednesday near HSA levels, then slowly decline through rest of the week.
For the north and west facing shores, surf is expected to increase today as a swell generated by a storm-force low (former Tropical Cyclone Damrey) arrives. This swell is forecast to come in from the northwest (310 degrees), then gradually transition over to north- northwest (340 degrees) by early next week.
