Swell Summary

The south swell continues to decline with a very small, long period reinforcement filling in today. Small, long period south swell energy originating from current Southern Hemispheric gales southeast of New Zealand is timed to arrive toward the middle of next week.

The return of fresh trades has caused a steady increase in east facing shore surf. East surf should hold at seasonable levels over the next several days per these amped up trades over and upstream of the region.

A small, medium period northwest swell is expected to reach the islands late Saturday into Sunday. A series of slightly larger, medium period northwest swells emanating from a weekend North Pacific gale low will come through next week. These swells should lift mid week north and west facing shore surf up to near normal September heights.
