Friday 10 25 19 morning call

All those fetches in the Tasman Sea might not do all that much for us, but they sure do something in Fiji. Cloudbreak yesterday by Brothers Surf Tours.



4am significant buoy readings and discussion
South shore
Barbers
2ft @ 12s from 279° (W)

Lanai
1.1ft @ 11s from 230° (SW)

Small Westerly energy most likely coming from one of the typhoons off Japan, I doubt the south shore will have much, but do check the Lahaina and Kihei webcams to find out.
6am update: nothing at the webcams.


North shore
NW101
9.5ft @ 12s from 343° (NNW)
5.2ft @ 10s from 338° (NNW)

Waimea
2.7ft @ 13s from 315° (NW)
2.1ft @ 9s from 336° (NNW)
1ft @ 16s from 299° (WNW)

Pauwela
4ft @ 9s from 67° (ENE)
1.8ft @ 12s from 324° (NW)
1.2ft @ 11s from 338° (NNW)

NW buoy jumped up, below is the graphs of the three reported buoys. The rise at the first one started around 10am. By applying GP's rule of thumb for the travelling time (16h@16s +/- 1h per 1s) we know that at 12s a swell takes around 20h to get here, so we should see this swell starting to rise locally at dawn. Obviously is not going to go all the way up to 10ft, but it will sure come up quite a bit throughout all day. Very good wind (or lack of thereof) until 9-10am an all the north shore.

Wind map at noon.


North Pacific shows the deep low in the NW corner and its fetch, which is only partially oriented towards us at the moment. The blue section in fact is aiming west of us (at the Marshalls). Nonetheless, the waves are going to be big Monday/Tuesday, possibly already Sunday.


A low like that deserves an old school weather map to show that it reached 964mb. Glad to have find again this page (the address I previously had was stuck to June), which I linked at link n.1.


Nice but not particularly intense fetch east of New Zealand.


Morning sky.
