4am significant buoy readings and discussion.
South shore
1.7ft @ 14s from 191° (SSW)
0.8ft @ 20s from 185° (S)            

1.7ft @ 14s from 193° (SSW)     
0.8ft @ 20s from 192° (SSW)            

Old southerly energy holding up at 14s while new long period one hits the buoys too. Today should see the slow start of a series of southerly swells which should provide some days  of above average size. Pat Caldwell lengthily described the complex evolution of the fetches. I'll grab the one related to this new long period pulse:

Another low-pressure system in the high-latitude, zonal track aforementioned reached 170E SSE of New Zealand 6/9. It was much stronger with storm-force winds and seas to 35 feet, as validated 6/10 by the JASON altimeter. This event is expected to be a notch larger than the local event of 6/14-15. The onset stage for the new one should start early Tuesday from 180-200 degrees and be filled in by Wednesday 6/17. It should peak a notch above average late Wednesday then slowly drop toward background by Friday as a new event slowly begins

Below is the collage of the maps of June 9, 10 and 11.

Check the Lahaina webcam if interested, for size, conditions and consistency. It started onshore, but it's cleaning up.

North shore
5.5ft @ 8s from 82° (E)            

Small waves at Hookipa, bigger on eastern exposures.

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):
