HST, ,

Swell Summary

Long period forerunners from an approaching northwest swell reached the offshore 51001 and 51101 buoys late this morning. This has a moderate size, long period swell reaching Kauai and Oahu this evening, Maui around Midnight Monday. Swell will fill in around all islands during the overnight hours and produce advisory level surf along many north and west-facing shores of the smaller islands by late Monday morning. A High Surf Advisory will be in effect from Monday morning through Tuesday afternoon to account for over double head high surf that should peak along many north and west-facing shores early Tuesday. Surf will begin to gradually fall from Tuesday night through Thursday.

A series of very small, medium period southern swell impulses coming from a couple of fast-moving southern gales passing south of New Zealand will pass through this week.

East-facing shore wind wave chop will be small the next couple of days. More rough surf will occur later this week as trades build over and upwind of the islands .
