Swell Summary
Surf along south facing shores will be on the increase over the next day or so as a long-period south swell arrives, potentially reaching High Surf Advisory (HSA) levels Wednesday. Surf heights may briefly ease a little Thursday, but a powerful long-period south swell will arrive late in the week, extending through the weekend. Peak surf heights with this second swell will easily reach High Surf Advisory criteria of 10 foot faces, with potential for surf to reach High Surf Warning levels of 15 foot faces.
Surf along east facing shores will remain elevated and rough through the week, especially as the winds ramp up through the midweek period, and again this weekend. Swells generated by tropical cyclone Darby will probably be biggest along east facing shores of the Big Island, where a High Surf Advisory may be required this weekend.
