Swell Summary
The current northwest swell will gradually decline over the next 24 hours, and forerunners of another northwest swell will arrive late Tuesday. The new swell will slowly build through Wednesday and peak Wednesday night and Thursday, leading to advisory level surf across most north and west facing shores from Kauai to Maui. As this swell declines late Thursday and Friday, a storm low centered 600 to 700 nm north of Hawaii will send a medium period north swell that could produce advisory surf for north shores. The north swell will lower through the weekend and may be followed by a moderate to large northwest swell on next Monday.
East shore surf surf will decline overnight as trades diminish, though a small pulse of short period northeast swell will be possible Tuesday and Wednesday. Aside from areas exposed to wrapping north swell Thursday into the weekend, east shore surf will be small. The recent out of season south swell will fade by tomorrow, bringing back typical wintertime conditions for south shores.
