12 4 16 morning call

Couple of sessions for me yesterday (NW and wind swells), both fun. This photo by Jimmie Hepp out of this gallery shows the conditions at Hookipa later in the day.

4am significant buoy readings
South shore
1.6ft @ 16s from 216° (SW)
That's the energy coming from that fetch in the Tasman Sea (8 days ago) that I pointed out yesterday.
Check the Lahaina webcam to see if it's enough for you.

North shore
10.3ft @ 13s from 345° (NNW)

8.4ft @ 13s from 340° (NNW)

6.7ft @ 10s from 87° (E)
3.7ft @ 13s from 338° (NNW)

Below is the graph of NW, Hanalei and Pauwela. As you can see from it, the direction turned NNW at all of them. I put two arrows on the NW buoy to show when there was a 2 feet increment, roughly starting around noon yesterday. The graph is kind of hard to read because of that color change on the NW swell line, so for once I took the black line (sum of all the energies of the swells in the water) as a reference. The same increment seems to have happened in Hanalei already, which is reassuring. Applying GP's rule of thumb for the travelling time from the NW buoy to Maui (12h at 18s, 15h at 15s, 18h at 12s), we should see a similar increment in Maui right around sunrise.

Below is the wind map of Dec 1st showing a very wide fetch NW of us. But, as you can see from the darker color indicating stronger wind, it's its easternmost part of it (the one that sits NNW of us) that offered fairly strong winds and as such created the NNW pulse on offer today.

That's the bump that Jessi Miley-Dyer didn't trust waiting for, to eventually finish the Honolua contest today. No blame, she finished the contest yesterday, but today the waves at the Bay will be bigger IMO, since that direction doesn't get blocked at all.
Don't forget the windswell, this might be the last day to surf it, if you like softer shorter period waves.

The Windguru table below shows a lovely week of no to very light wind. Notice the heavy rain forecast around Thursday though.

Current wind map shows three fetches that are the sections oriented towards us of the clockwise wind rotation around three different high pressures. These fetches usually are never really strong and generate swells of short to moderate period. The north Pacific dominated by high pressures is still a far from typical winter configuration. We're just lucky that we're gonna be in a no to light wind area between them. As a consequence, the long term forecast doesn't show anything major. Plenty of small to moderate, clean swells instead, which I don't mind at all.

NAM3km map at noon shows a completely calm situation: 0 knots at Hookipa! I can foresee the first excellent condition scores since I started ranking them. When was that, couple of months ago? Stay tuned for the beach report to see if that really happens.
