Swell Summary
The current moderate northwest swell (320 to 330 degrees) will continue to gradually decline through Friday. However, a new small, medium period north-northwest swell (330 to 340 degrees) will build in Friday night, providing a small, short lived boost to surf along north and select west facing shores this weekend.
A series of overlapping south and southwest swells will keep south shore surf slightly elevated into early next week. A reinforcing, tiny long period southwest (220 degrees) swell will build on Friday, keeping small surf along south facing shores. The next small, long period south-southwest swell (200 degrees) is expected to fill in Monday and peak Tuesday into Wednesday. This could bring near to slightly above average surf along south facing shores.
East facing shores will remain small through early next week due to the lack of strong trades both locally and upstream.
