Swell Summary
Surf along south facing shores remains elevated from a moderate, medium to long period swell that filled in last night. However, it is still expected to slowly decline through midweek. Some wrap also continues this evening for west facing shores, but this is also expected to follow suit as the south swell declines. Another long period south swell generated from gales just south and east of New Zealand will begin arriving late this week.

Surf along east facing shores will continue to fade tonight as Lala moves further west away from the state and as trades decrease on Tuesday. North facing shores will remain tiny throughout the week.
