Detailed Forecast


Synopsis: Rising seas will continue as a powerful onshore swell persists. Seas will reach Small Craft Advisory levels offshore overnight with lower seas around 4 to 6 ft for the inner waters. A north northeasterly wind will prevail through the weekend as high pressure remains situated to the north and a coastal trough develops. A weak front will reinforce onshore winds Monday and Tuesday before winds trend southerly then offshore ahead of an approaching cold front on Wednesday. Showers and storms are expected along the second cold front as it pushes across the waters Thursday. Strong northwesterly winds will trail behind this front and persist into next weekend.
