Swell Summary

South facing shores will remain small through the weekend with mainly medium period background energy. A storm force low east of New Zealand has produced seas up to 40 feet per JSON satellite observations, likely impacting the islands during the second half of next week. Confidence has increased that this low will generate a moderate to large long period south swell that may approach or exceed the High Surf Advisory threshold as it peaks.

East facing shores will gradually decline this weekend as trade winds weaken locally and upstream of the state. East shores should then increase next week as trade wind speeds increase. Flat to tiny surf expected along north facing shores through the week.
