Swell Summary
Surf along south facing shores will remain small through the weekend as a small background south southwest swell moves through. A small, long period south swell is expected to gradually build at the start of next week, with surf peaking near average Tuesday before slowly tapering off through the second half of next week. Rough, choppy east- facing shore surf may drop a touch over the weekend as trade winds ease slightly locally and upstream but should pick right back up next week. A very small northwest swell may pass through early next week, providing tiny surf along north facing shores Monday and Tuesday before becoming nearly flat through the remain forecast period.
