... "old school" windsurfing backloops? In this case I admit that the backloop wins, but the debate is still open.
Even just a tail wing breach (red arrow) caused Bobo an overfoil wipeout.
4am significant buoy readings and discussion.
South shore
Barbers
2.3ft @ 9s from 169° (SSE)
1.5ft @ 12s from 190° (S)
Lanai
1.9ft @ 13s from 195° (SSW)
1.8ft @ 6s from 148° (SE)
I was quite surprised to read this on the top part of Pat Caldwell's page (which someone else writes): "Surf along south facing shores will be 2 to 4 feet today, rising to 3 to 5 feet Monday" and "A south swell arriving tonight, and another bump Monday night will help to boost surf along south facing shores". Uncle Pat himself didn't put any new southerly energy in his Friday table, until Tuesday. So I went to check the fetch maps (below are July 26 to 28) and there's absolutely nothing that would justify such claims. Next fetch was on Tuesday July 29 (so decent swell mid week), but we'll talk about that later. We'll see how it goes, but I'm afraid someone got a bit excited at NOAA.
Today we have declining 12-13s energy and the early observation of the Lahaina webcam shows inconsistent and small but nice sets. Check it yourself if interested, for size, conditions and consistency.
North shore
N
5ft @ 10s from 41° (NE)
Pauwela
4.1ft @ 7s from 65° (ENE)
2.9ft @ 11s from 13° (NNE)
As I suspected, the NNE swell generated by the Gulf of Alaska fetch I posted two days ago, is showing bigger than predicted by Pat Caldwell (2ft 11s) and Surfline (2.6ft 10s). For your convenience here's another collage of the maps of July 29 and 30 showing it again.
These are the graphs of the N and Pauwela buoys. The swell changed color 5 times on the first (Surfline could definitely improve that automatic color change), but it is now a "pumping" 5ft 10s up there. In the post Buoys to Maui travel times and Maui's shadow lines you can see that at 11s it takes 12h to get here, so I drew my prediction of the day in a red dotted line on Pauwela's graph. Possibly getting close to 4ft 10s during the day (the shorter the period, the greater the decay with travel). Plenty opportunities to enjoy this "surprise" (if you don't read this blog) little swell on the north shore. Make the most of it and enjoy!
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.
