A slowly declining medium period northwest (330 degree) swell continues to produce High Surf Advisory (HSA) level surf for the north and west-facing shores of Niihau, Kauai, and Oahu through Thursday.
On Thursday, a gale force low deepening north of Hawaii will produce a north to south fetch aimed directly at the islands. The close proximity of this source will lead to a brief relatively large, medium period northwest swell (310-320 degrees) swell moving into the islands on Thursday. The swell direction will shift more northerly (350-010 degree) direction by Friday as the fetch area drifts slowly eastward with the parent low center. Expect surf heights along north and west facing shores to build above High Surf Warning thresholds from Thursday night through Friday. The surf along north and west facing shores will then decrease to HSA thresholds by Saturday as the swell energy declines. Small surf continues along south and east facing shores through the week.
