Saturday 6 20 20 morning call

Been doing a lot of this lately, got a new board to try today. This is Scot by Tony.

4am significant buoy readings and discussion.
South shore
1.8ft @ 16s from 188° (S)
1.1ft @ 13s from 192° (SSW)

1.4ft @ 16s from 187° (S)            

New long period pulse has arrived and it's quite modest. Pat Caldwell correctly predicted that due to the lack of strength in the wind in the fetch:
The second phase (third in my count) is from the occlusion of the low-pressure system south of French for 6/13-14. A strong high pressure near New Zealand in combination with the slow, eastward-moving low south of French Polynesia set up a long, wide fetch over the 170-190 degree band aimed at Hawaii with the head of the fetch reaching 35S or about 3500 nm away 6/14-15. The limiting factor for surf in Hawaii was the magnitude deficient winds that stayed mostly at the low end of the gale range. There were compact areas of stronger winds for a short duration. The seas stayed below 25 feet. Given the reach of the fetch into the subtropics, the direct aim, and the wide, long fetch, surf in Hawaii should climb above average. It should be much less than the recent large S event that peaked locally 6/3.

Below are the maps of June 13, 14 and 15.

Check the Lahaina webcam if interested, for size, conditions and consistency: onshore at the moment.

North shore
4.6ft @ 8s from 75° (ENE)            

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):

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

Morning sky.
