Tuesday 4 19 22 morning call

It was a beautiful day of light wind foiling on the north shore.

Prototype n.3 of a low drag stabilizer for downwinders worked very nice (the end of the stick is out of the picture, but it ends right there). I now have a pretty good idea of the area the tail I have in mind needs to have. Problem is that I tested it with the 1125, while I'm looking for a tail for the 725. Will look under the house for a relatively thin plank of wood for a possible prototype 4, or just go straight to someone who can build it.

6am Surfline significant buoy readings and discussion.

South shore
Barbers
1.5ft at 13s S 190º

Southerly energy continues its decline, but there's still some at Barbers. Check the Lahaina and Kihei webcam if interested, for size, conditions and consistency.

North shore
NW001
1.3ft @ 18s from 45° (NE)

Hanalei

2.4ft @ 13s from 333° (NNW)

0.6ft @ 20s from 300° (WNW)

Waimea

1.9ft @ 12s from 344° (NNW)

0.6ft @ 22s from 342° (NNW)

Mokapu

5ft @ 7s from 45° (NE)

4.6ft @ 8s from 54° (ENE)

1.9ft @ 12s from 27° (NNE)

First an update on the Pauwela buoy: I met my friend who deploys it and he told me that the last buoy was new, but the mooring was old and it broke. They rescued the buoy (which is now safely resting in Haiku) and they're waiting for the new mooring to arrive. A few weeks, he said.

New long period WNW energy is at the upstream buoys (direction is likely correct only at Hanalei). Below are the maps of April 16 through 19 that show the fetch of ex typhoon Malakas that generated it.

As you can see in the first two maps, it raced towards the Aleutians at high speed across the great circle rays, which limited the generation of waves. Consequently, the Surfline forecast below only predicts 0.7ft 20s from 304 for this afternoon. After that, the low intensified and slowed down (last two maps) and even though it was mostly aimed to our NE, we should get much more energy out of the angular spreading of this swell tomorrow and Thursday.


Home guess for Hookipa is for waist to head high, thanks to the medium period NW energy still in the water and the windswell. Long period small westerly lines might start showing in the afternoon.
