Swell Summary
A background east swell will keep moderate surf heights along east facing shores into the weekend. This east swell will slowly fade from Saturday night through Monday. A high pressure system building into the central Pacific early next week will increase east swell heights from Tuesday onward. Small surf heights along north and west facing shores will continue through this afternoon. A new large medium period north to northeast swell will arrive later tonight through Saturday morning near Kauai and Oahu, surf heights will quickly build along north and east facing shores to High Surf Advisory levels through this weekend. West facing shores will see less of an increase in surf heights due to the north to northeast swell energy. Small surf along south facing shores will rise a bit on today and Saturday as a swell originating west of New Zealand reaches the area.
