Hookipa yesterday afternoon.
5am Surfline significant buoy readings and discussion.
Small long period southerly energy at Barbers. Check the Lahaina
webcam if interested, for size, conditions and consistency.
4ft @ 10s from 24° (NNE)
2.1ft @ 11s from 351° (N)
Interesting reading of NNE energy at the north buoy. To examine where it came from, let's first look at the position of the buoys around Hawaii. The N buoy is 212 nm out at a 42 degrees angle.
Below are the maps of Oct 15 through 18. The energy at the N buoy (and Waimea) probably comes from the angular spreading of the fetch I indicated with blue arrows. It should be bigger in Maui than in Oahu, so we could have up to 3ft 10s locally. That might give relatively organized waves in the head high range.
The red arrows instead indicate the fetch that generated the first of a couple of NW to N pulses that will start arriving tomorrow evening (yellow dotted line on the Pacioos forecast below).
