Swell Summary
Current medium period north-northwest swell should peak tonight then gradually decline on Sunday. This swell should gradually veer towards the north as it declines. A similar or slightly larger, medium period northwest should arrive on Tuesday and peak late Tuesday, then shift directions out of the north on Wednesday as it declines. Several small swells from the north should maintain some small surf along north facing shores during the second half of next week.
A series of small long-period southwest swell should provide some small but inconsistent waves along south facing shores the next few days. A slightly larger south-southwest swell should fill in next Tuesday and hold through Wednesday then decline through the rest of the work week. A moderate south-southwest is possible next weekend with long-period forerunners filling in next Saturday and likely peaking on Sunday Oct 5th with swell heights of around 3 to 4 ft.
East shore surf will remain small, although select spots with more northerly exposure could see some of the north swells throughout the upcoming week.
