Sunday 10 31 21 morning call

Hookipa yesterday morning.


4am Surfline significant buoy readings and discussion.
South shore
Barbers
1.5ft @ 13s from 190° (S)

Small southerly energy at Barbers. Check the Lahaina webcam if interested, for size, conditions and consistency.

North shore
NW101
6ft @ 15s from 330° (NW)

Hanalei
3.2ft @ 17s from 324° (NW)

Waimea

3.4ft @ 9s from 348° (NNW)
2.5ft @ 16s from 319° (NW)

New long period NW swell is rising at the upstream buoys. Here's how Pat Caldwell starts his  description of the evolution of the fetch:
The next event is associated with a low-pressure system that tracked from Japan 10/26 to a position north of Hawaii near 50N, 160W 10/29. This will give a spread of wave direction within 305-360 degrees with largest surf expected from 315-360 degrees. The wave generation is explained in three parts... you can read the rest on his page if interested. Or you can just look at the fetch in below's collage of Oct 26 through 30. I would recommend both.


Below are the graphs of NW101 and Hanalei together with the Surfine forecast. The red dotted line is my prediction of how the swell will rise locally. Probably starting with 1-2ft 17s at dawn and up to around 5ft 15s at sunset.


Home guess for Hookipa is head to head and half (still 9s NNW energy in the water) with size rising to double plus throughout the day.

Forecast of Pauwela from this PACIOOS page.
