Swell Summary

A large, long-period northeast swell from a broad gale centered around 1600 nm northeast of the state has generated warning level surf for east facing shores this morning. Exposed north facing shores will also see an increase today as the northeast swell fills in to advisory levels. 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 small medium-period northwest swell fills in tonight through Tuesday. The next larger northwest swell builds in near High Surf Advisory levels for north facing shores from Thursday to Friday.
