Wednesday 11 27 19 morning call

Bit of a transition day yesterday (as far as NW swells go), this is my pick of Jimmie Hepp's album of the windsurfing action at Hookipa.


Happy to share a little technical analysis of a take off I, that I sent to one of my regular surf students:

I was watching the condensed replay of a heat at the recent Haleiwa contest, when I noticed Ryan Callinan doing something we've talked about already. I took four shapshots to show you how he's looking down the line while he's paddling, then he looks at the landing spot of the take off for less than a second, just to have a last minute view at how it looks down there, and then as soon as he pops up on his feet, he's already looking again down the line. He'll keep his eyes on the place where he wants to go throughout the whole wave, including the turns.

You can check the wave in the video at around minute 1:25.

Also, notice how he put his right hand a bit more forward than usual, because he needed to push the nose down the wave to make sure he caught it.
AND, by doing so, he also enabled his front hip to come up a bit more forward than his left one, hence facilitating the pop up.
AND, by doing so, he also engaged the inside rail already, so that the board will start cutting across the open face even before he's up. Not all waves require that, only the ones peeling fast down the line.
See how many important little things he achieved just by placing his front hand a bit more forward (and loading it with the right amount of weight)!

3 am significant buoy readings and discussion.
South shore
No indication of southerly energy at the buoys, check the Lahaina webcam to see if there's any ripples.

North shore
NW101
8.1ft @ 13s from 316° (NW)

Waimea
5.1ft @ 15s from 307° (WNW)

Pauwela
6.2ft @ 10s from 64° (ENE)
3.1ft @ 7s from 67° (ENE)
2.4ft @ 16s from 321° (NW)
2.4ft @ 12s from 345° (NNW)
 
New NW swell on the rise, let's see how Pat Caldwell described the fetch that caused it.
An upper level trough pinched off into a cut-off low near 40N, 175W late Saturday 11/23. At the surface, a slow-moving gale has had highest seas over a long fetch from mostly north to south aiming southward at targets west of Hawaii 11/24-25. A shorter fetch with marginal gales aimed directly at Hawaii over the 310-320 degree band. This energy plus the angular spreading should trend up in the wee hours Wednesday to near the average during the day from 300-320 degrees. The low is modelled to weaken sharply 11/26. Heights should drop below average from 300-330 degrees on Thursday 11/28, then fade on Friday into Saturday 11/29-30.

Below are the fetch maps of Nov 24 and 25. Red circles indicate the direct aim, blue circles, the possible angular spreading.
 
Below are the graphs of the three reported buoys, plus the Surfline forecast which seems to be a little late again (in the corner). NW101 peaked around 4pm yesterday at around 10ft 13s. At 13s it takes 19h for the energy to get here, so we can expect the swell to peak locally in the early afternoon. Pretty west for Honolua, they might wait until the afternoon to see how's the size over there. No problem instead for the north shore, which will definitely be pumping in the afternoon, and let's not forget 6ft 10s from 64 which will light up the eastern exposures.


Wind map at noon. Should be calm all morning.


Kahului Tides
High Tide     High Tide     Low Tide     Low Tide       Sunrise   Sunset
3:16a  +2.8   2:02p  +1.5   9:39a  +0.9   8:30p  -0.4    6:45a   5:45p    

North Pacific has a small NNW fetch and the windswell one. The first one will intensify in the next couple of days and give life to the weekends N swell which is now predicted to peak at 10ft 16s Sunday night. Almost guaranteed that Sunday/Monday are going to be contest days at Honolua.


Tiny little fetch in the Tasman Sea. Too small to do anything for us.


Morning sky.
