4am significant buoy readings
North shore
NW101
1.8ft @ 15s from 328° (NW)
Hanalei
1.9ft @ 11s from 330° (NW)
0.6ft @ 16s from 320° (NW)
Waimea
1.6ft @ 12s from 352° (N)
Pauwela
4.1ft @ 9s from 98° (E)
Lanai
1.4ft @ 12s from 347° (NNW)
1ft @ 11s from 15° (NNE)
Relatively easy read of the buoys this morning. NW101 has new low long period energy that Hanalei is just starting to feel too. As mentioned in the epic post Buoys to Maui travel times and Maui's shadow lines, the travel time from Kauai to Maui at 16s is about 8 hours. That means that those 0.6f 16s (or whatever is left of them after the extra travel) is going to hit Maui around noon. That also mean that in the late afternoon this new energy should start being visible, also considering the lack of other significant swells.
As far as the morning goes, Pauwela reads a 98 degrees windswell, which might completely miss Hookipa, which will then only have minimal energy left from the northerly quadrants and be once again close to flat (it happened just before the recent giant swell).
Here's the shadow line for Waiehu: 80 degrees. Which means that a good part of that easterly energy will be blocked there too, but for sure there will be more than at Hookipa. Relatively short periods like 9s still wrap around land points, but can't do as sharp as a turn as long period ones. Hookipa has a shadow line of 65 degrees and it requires a much sharper bend, which justifies the sentence above.

South shore
Barbers
0.1ft @ 25s from 191° (SSW)
Lanai
0.8ft @ 14s from 192° (SSW)
I reported that Barbers reading for the sake of statistics, you don't see 25s often. Only a tenth of a foot though, so impossible to detect in the water. Lanai has almost a foot 14s, that should make for ankle to knee high waves on the Lahaina side.
Wind map at noon.
North Pacific has an articulate fetch in the NW corner. Too bad the low north of us has not generated much just yet. Thanks anyway for the lovely southerly flow.
South Pacific has a small fetch in the Tasman Sea.
Morning sky.
