Saturday 10 10 20 morning call

Hookipa yesterday morning. Looks like Charlie Smith.

3am significant buoy readings and discussion.
South shore

2.8ft @ 9s from 170° (S)
1.5ft @ 14s from 179° (S)
1.3ft @ 11s from 177° (S)
1.1ft @ 12s from 190° (S)

2.2ft @ 14s from 178° (S)

Decent numbers at Lanai, bit tricky to find out where this energy comes from. Let's see if Pat Caldwell helps:
A severe gale S to SE of New Zealand 10/2-3 aimed highest seas at the Americas. The PacIOOS/CDIP Barbers buoy 10/9 does show a rise in the 15-17 second band from this source. It should be filled in Saturday at heights within background to average from 180-220 degrees. A gale subtropical low south of French Polynesia 10/4-5 could add similar background-to-average surf 10/11-13 from 170-190 degrees.

Below is the collage of the maps of Oct 3, 4 and 5 that might help follow.

Check the Lahaina webcam if interested, for size, conditions and consistency.

North shore

4.6ft @ 9s from 46° (NE)

2.5ft @ 10s from 15° (NNE)

4.5ft @ 10s from 30° (NNE)

5.1ft @ 10s from 32° (NE)

NNW swell is gone, now we have NNE energy at the buoys surrounding us. Below is the collage of the maps of Oct 6, 7 and 8 that show the originating fetch (red arrow). Not the most impressive fetch, but we can assume that also locally there's 4-5ft 10s, so Hookipa and eastern exposures should have fun size waves.

Wind map at noon (the other ones can be found at link n.-2 of GP's meteo websites list in the right column).

Fetches map (circles legend: red: direct aim, blue: angular spreading, black: blocked, yellow: apparent direct aim, but out of the great circle ray map, so not 100% sure).
North Pacific (about 4 days travel time from the NW corner of the North Pacific):

South Pacific (about 7 days travel time from east/west of New Zealand):

Morning sky.
