4am significant buoy readings
2.3ft @ 15s from 188° (S)
3.5ft @ 14s from 186° (S)
South swell continues to impress with still 3.5ft 14s at Lanai, while the new long period pulse we discussed on Wednesday based on the Samoa buoy readings shows up right on time. Still relatively small at Barbers, but now that you saw what 4ft 18s can do, you can imagine that 0.7ft 22s is not that small after all. Those sets are going to be very inconsistent compared to the 14s ones. Meanwhile, the conditions in Lahaina are absolutely gorgeous again. Check the webcam before going.
3.3ft @ 8s from 106° (ESE)
Hilo might be feeling something from Barbara already, even though the Surfline forecast only sees that energy rise tomorrow. It still has it at an impressive 5.7ft 15 from 100 degrees (and with very little direction spread +-4 degrees, since it comes from a very compact fetch). For your convenience, I drew the 100 degrees shadow line for the east facing shore of West Maui. You'd have to go all the way to Kahakuloa to feel no blockage, but at 15s, I believe that some of the energy will be able to wrap around Pauwela Point and reach Waiehu. How big is it going to be over there? Impossible to say. All I can say is that if it was from an unblocked direction, let's say 70, it would easily be double overhead. Obviously, Hana will have big waves, as it's not blocked.
Wind map at noon.
North Pacific has a weak NW fetch and the strong but tiny E one associated with Barbara.
South Pacific has a narrow fetch just east of New Zealand and a much bigger/stronger one SE of it, this last one aiming at the Americas, but we should get some angular spreading out of it.
