3am significant buoy readings and discussion.
South shore
Barbers
2ft @ 13s from 191° (SSW)
Lanai
1.9ft @ 13s from 197° (SSW)
Southerly energy slowly coming down in period, but there should still be some small waves also today. Check the Lahaina webcam if interested, for size, conditions and consistency.
North shore
NW001
3.2ft @ 12s from 297° (WNW)
Pauwela
4.3ft @ 7s from 60° (ENE)
0.6ft @ 13s from 329° (NW)
The NW001 buoy shows some 12s energy from questionable direction that could be the expected small NW swell. No other buoys shows it, other than Pauwela with that 0.6ft 13s (and a much more reliable direction). Below are the maps of September 4, 5 and 6 showing the fetch that generated it.
Been a while since we needed to use GP's rule of thumb for calculating the travel time from the NW buoy, so here it is again: 16h at 16s (+1h -1s and viceversa for different periods)
At 12s it takes roughly 20h to get here, so this swell should slowly build in the late afternoon and peak tomorrow.
For today, the easterly windswell should still rule, so tiny waves at Hookipa and 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.
