Wednesday 8 19 20 morning call

Thanks to blog reader Renew Your Spirit for the donation.

Facebook memories proposed this shot from three years ago. Obviously Indonesia and I remember that wave pretty well. Should have slowed down a lot more.


These guys challenge the barrels on a shore break instead.


5am significant buoy readings and discussion.
South shore
Barbers
2.5ft @ 14s from 184° (S)

Lanai
2.7ft @ 15s from 184° (S)

Bigger numbers at the buoys and bigger waves in the water. Check the Lahaina webcam if interested, for size, conditions and consistency, today I included also Ala Moana in the picture. Choke people in both places.
Oahu has been bigger than Maui in this swell, but I'm not surprised, as there's a certain threshold of size under which the influence of Kahoolawe is felt more. Today it seems that the size has gone just a bit above that. The other factor that made this swell "under perform" so far (compare to what?!) is that its fetches were quite fragmented. If you scroll down to the day I posted the last collage of southern hemisphere maps, you'll notice that the fetches look better on the 12, a week ago. That's why today  it's a bit bigger. Most of the answers are often in the fetches.


North shore
Pauwela
2.5ft @ 6s from 76° (ENE)
2.2ft @ 7s from 74° (ENE)

Flat everywhere on the north shore.

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.
