Swell Summary

A south swell is expected to build tonight, then peak around the advisory level Monday night into early Wednesday. A High Surf Advisory will likely be required through this period. As this swell slowly fades during the middle of the week, a new long period south swell will arrive on Thursday, keeping surf elevated through next weekend.

Surf along north-facing shores will remain at flat to tiny levels through next weekend.

Surf along east facing shores will lower slightly Monday through Wednesday as the trades ease upstream of the islands. East shore surf should then build back close to seasonal levels late in the week through next weekend. Additionally, swell from Tropical Storm Elida may give a slight boost to east shore surf during the middle of the week.
