Swell Summary
A large, medium-period north to northeast swell arriving from a broad gale centered around 1600 nm northeast of the state will support warning level surf for east facing shores and advisory level surf for north facing shores Monday through Tuesday. A smaller north-northwest medium period swell will also fill in today, helping to boost surf along west facing shores. A small long period south swell will build into the region with a slight bump in south shore surf activity lasting into Tuesday.
Surf along north and west facing shores will remain elevated through Wednesday as medium to long period northwest swell energy moves through the region. The next larger northwest swell builds in near High Surf Advisory levels for north facing shores from Thursday to Friday.
