3am Surfline significant buoy readings and discussion.
South shore
Barbers
3.6ft @ 14s from 186° (S)

Lanai
2.4ft @ 15s from 189° (S)

1ft @ 20s from 193° (SSW)

Second pulse of south swell on the rise today (1ft 20s at Lanai) while the first one still healthy at the buoys. Let's see how Pat Caldwell described the evolution of the fetch.

The second source was much stronger and broader. It started SE of New Zealand Saturday 6/12. It gained storm-force status, with a wide, long fetch aimed just SE of Hawaii 6/13 reaching to near 40S, 150W (3700 nm away, just east of the Hawaii swell window) early 6/14. It moved well east of the Hawaii swell window 6/15.

This source was close enough in aim and large enough in expanse to bring in above average surf locally. It should have slow onset on Saturday 6/19 from 185-195 degrees. It is expected to be filled in by Sunday 6/20. It should peak late Sunday 6/20 a couple of notches above average. It should remain above average 6/21 and drop to near to a notch above average 6/22 from 180-195 degrees.

Below is the re-post of the maps of June 10 through 14 that will help follow.

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

North shore
Pauwela

3.3ft @ 8s from 90° (E)

1.3ft @ 6s from 70° (ENE)

Very small easterly windswells at Pauwela means that the north shore will be completely flat today. But don't give up on it. Check the fetch map below and you'll see that it's not quite over just yet.
