Swell Summary
Small surf will persist along north facing shores into the evening. A fresh, long period northwest swell will build late tonight and Tuesday, pushing surf along north and west facing shores to near seasonal average through Wednesday. This swell will decline Thursday and Friday. A medium period north- northwest swell will build late Friday and will be the main source to produce surf around seasonal average during the weekend, though a small longer period northwest swell will also arrive during the weekend.
South shore surf will remain above seasonal average through the afternoon then gradually lower tonight through Wednesday as a long period south-southwest swell slowly declines. Another long period south swell will produce surf near seasonal average Friday and Saturday.
Surf along east facing shores will remain small through Thursday as small wind waves and tiny east swell persist. Choppy surf will increase slightly as trade winds strengthen across the region Friday into the weekend.
