Swell Summary
The large, long period south southwest swell that brought warning level surf to the state earlier this week will continue to slowly decline. A High Surf Advisory (HSA) remains in effect through tonight for all south facing shores. Surf heights are expected to drop below advisory levels by Wednesday. Another moderate, long period, south southwest swell is expected to fill in Wednesday night into Thursday that could push surf back up to HSA levels along south facing shores. This swell will slowly fade Friday through the weekend.
Surf along north facing shores will remain flat to tiny through the forecast period. Surf along east facing shores will remain below average as easterly trade winds ease through the end of the week.
