5am significant buoy readings and discussion.
South shore
Barbers
1.7ft @ 14s from 196° (SSW)
Lanai
1.4ft @ 14s from 197° (SSW)
Surprising SSW energy at the buoys, I can't find any fetches that would make that on my maps. Check the Lahaina webcam if interested, for size, conditions and consistency. Looks like a southerly flow, so conditions are pretty bad.
North shore
NW101
2.6ft @ 17s from 270° (W)
Hanalei
1.6ft @ 18s from 313° (NW)
Waimea
2.6ft @ 9s from 317° (NW)
2.5ft @ 11s from 323° (NW)
1.2ft @ 18s from 309° (WNW)
Pauwela
3ft @ 8s from 56° (ENE)
2.5ft @ 11s from 324° (NW)
1.3ft @ 6s from 69° (ENE)
0.9ft @ 20s from 323° (NW)
The first pulse of the closely generated NW swell went down quickly (as the history of the fetch would suggest), but already tomorrow a reinforcement of about 11-12s should arrive. Today we have also a new low, long period WNW swell arriving from much more distant. Below are the maps of April 2, 3 and 4. The black arrow points at the remote source, which was never particularly strong or wide and moved across the rays circle, hence limiting the surf production. The modest, although long period, readings of this morning confirm the low expectations.
The red arrow points to the fetch associated to the nearby low instead. You can see that it was strongest on the 2nd (hence the waves were biggest Saturday night) and that it became much weaker the next couple of days (and that explains the small energy of today). Also notice how it sent most of its energy to our west, which also explains why the upstream islands stayed a bit bigger yesterday.
Overall, today is going to be a relatively small day for the Hookipa standards, with extremely clean conditions due to the lack of wind with a light southerly flow.

North Pacific fetches map (about 4 days travel time from the NW corner):
the nearby low is doing a good job at keeping the winds light and at creating medium period NW waves.
South Pacific fetches map (about 7 days travel time from east of New Zealand):
bit of a fetch in the Tasman Sea.
