10 21 17 morning call

A short SUP foil session for me in the morning yesterday but a very bad call in the evening made me miss out on more foil fun. Not gonna do that mistake again.

Casper Steinfath took the win in the Red Bull Heavy Water in San Francisco. Here's a photo that shows that the water really was heavy at the start at Ocean beach. How did they manage to go through that stuff?!


Here's a review of the Gofoil Maliko foil.
He's right about the learning being easier on it. That's the foil I use for my windfoil students.
And yesterday I actually managed to swap the back wings between my Maliko and Kai foils (one lined up perfectly, the other needed a small modification of the screw hole, but fitted nice after that), so I'm going to try those combinations too.


4am significant buoy readings
South shore
No southerly energy at the buoys, we have to wait until tomorrow for that, when a new long period swell should materialize.

North shore
N
5.7ft @ 13s from 346° (NNW)

Waimea
3.7ft @ 12s from 334° (NNW)

Mokapu
6.1ft @ 9s from 47° (NE)

As explained below, yesterday's NW swell is now not hitting the NW buoys anymore, but it's still present at the N buoy with a 346 degrees direction. Waimea reads 3.7f 12s, for a change we might get a bit more than that, due to the direction of the angular spreading illustrated below. But it will decline steadily throughout all day. Next NW swell should start tomorrow mid day.

These are the maps of October 16 and 17 that show the fetch of yesterday's NW swell. As you can see, the fetch was first aimed towards us, while today we should get the angular spreading of a swell aimed more towards the mainland west coast. That explains why the energy disappeared at the NW buoys, but it's still some at the N buoy. Don't know where the buoys are? There's a link to a map on GP's list of meteo websites on the right column of this blog.


Wind map at noon shows moderate trades.


North Pacific shows:
- the west fetch from the Typhoon south of Japan that moved very little again
- a wide but not particularly strong NW fetch
- the windswell fetch


South Pacific shows a fetch almost completely blocked by New Zealand.


Morning sky.
