Swell Summary
A large north northeast swell will bring advisory level surf to exposed shorelines today. These areas include the north, east and west facing shores of Kauai County, Molokai and Maui; as well as the north and east facing shores of Oahu and the Big Island. Some near advisory waves will also sneak into the coastline north of Keahole Point on the Big Island, and the north shore of Lanai. This swell will be on the decline Tuesday. A smaller northwest swell is possible Wednesday and Thursday. Trade wind swell will increase over the second half of the week. Surf along east facing shores will likely remain above advisory levels as winds strengthen.
