Swell Summary

A close proximity low pressure system to the north with northerly winds pointed towards the islands will send a moderate medium period N-NNE swell to N facing shores tonight and peak tomorrow afternoon. There is also a small NW swell that will be filling in tomorrow through the weekend helping to keep surf heights slightly elevated. A small medium period NW swell is then expected to fill in Monday and decline slowly through next week. Tiny to small background N and NW pules will keep north shores from going completely flat for the remainder of next week.

Surf for south facing shores will remain small through tomorrow before a small long period south swell arrives on Friday and peaks over the weekend at or slightly above the September average (5 ft).

Surf for east facing shores will stay small today then will likely see an increase from the N-NNE swell tomorrow and Friday. The islands to see the greatest increase would be Kauai and Oahu, as these islands are most directly within the fetch area of the low to the north. This swell will fade out by the weekend. Trade wind chop could increase by Sunday as trade winds return.
