Swell Summary
A moderate, medium-period north-northwest swell (340 degrees) generated by the formerly-gale force low north-northwest of the main Hawaiian islands is filling in along north and west facing shores this afternoon. This swell will maintain small to moderate surf through Monday, followed by a decline in northwest swell energy for the rest of the week.
A medium-period south swell will continue to decline through Monday. By Tuesday, however, a new south swell will arrive, once again providing a boost to surf along south facing shores through mid week before gradually subsiding into the weekend.
Surf along east facing shores will remain below seasonal average with lighter than average trade winds near and upstream of the islands forecast through next week.
