Swell Summary
A small, medium to long period south southwest swell will continue to build in through the day. This swell, in tandem with the arrival of a low, medium period southeast swell, has a High Surf Advisory (HSA) in effect through 6 AM HST Tuesday. A small, medium period easterly swell from former Tropical Cyclone Kay will also move around the chain through Tuesday. The combination of these three swells will keep surf elevated along many southeast and east-facing shorelines into the middle of the week.
