Wednesday 4 28 21 morning call

Hookipa yesterday morning.

6am Surfline significant buoy readings and discussion.
South shore

3.3ft @ 14s from 264° (W)
0.5ft @ 22s from 216° (SW)


3.6ft @ 14s from 270° (W)
0.7ft @ 22s from 233° (WSW)

Westerly energy from that cyclone off Japan is at the buoys. I expect the Kihei side to have waves (a couple of webcams are down). Notice the fractional reading of 22s SW energy, sign of a new slowly rising long period Tasman Sea swell (which will be more substantial tomorrow). Check the Lahaina or Kihei webcams if interested, for size, conditions and consistency.

North shore

4.4ft @ 12s from 310° (WNW)
3.4ft @ 7s from 21° (NNE)
2.1ft @ 10s from 319° (NW)


2.4ft @ 14s from 286° (WNW)
0.4ft @ 9s from 331° (NNW)


1.9ft @ 14s from 310° (WNW)
1.4ft @ 8s from 89° (E)

The 14s energy at Pauwela is the same westerly swell recorded by Lanai and Barbers, after it wrapped around the upstream islands and changed its direction. 310 is about as west as a Pauwela reading can physically be. I don't expect it to produce much at all, but Hookipa might have small inconsistent sets here and there to break the flatness, which otherwise will reign.
Btw, I just noticed that the wind meter on top of my house (right column) indicates strong wind from the ENE. That is obviously old/wrong as it's absolutely calm at the moment. Will have to investigate...
