Swell Summary
A small, medium period north-northwest swell will gradually decline through Monday as it shifts more northerly. A similar, or slightly larger, medium period northwest swell should arrive late Monday night, peak late Tuesday and Tuesday night, then decline as it shifts more northerly Wednesday and Thursday. Several additional small swells from the north should maintain some small surf along north facing shores Friday through next weekend.
A series of small long-period southwest swells should provide some small but inconsistent surf along south facing shores during the next couple days. A slightly larger south-southwest swell should fill in Tuesday, hold through Wednesday, then gradually decline through the rest of the work week. A small, long period south swell is expected to arrive on Saturday (October 5) and then hold into early next week, giving another boost to surf along south facing shores.
East shore surf will remain small through most of this week.
