Tuesday 12 10 19 morning call

Excellent waves yesterday morning at Hookipa. This one by Matias was the one that made me wax my board.


My turn to be on a beauty. It was glassy until around 9ish, then the wind went from 0 to 15 in 5 minutes.

This is my pick of Jimmie Hepp's  album of the windsurfing action.


4am significant buoy readings and discussion
South shore
No indication of southerly energy at the buoys, but they're feeling a bit of NW wrap, so it could be there but masked. Below are the maps of Dec 3,4 and 5, which show those couple of fetches I mentioned back then. Check the Lahaina webcam to see if there's something.


North shore
NW101
8.7ft @ 14s from 325° (NW)
3.6ft @ 10s from 345° (NNW)

Waimea
6ft @ 14s from 320° (NW)
3.6ft @ 11s from 329° (NW)
3.2ft @ 9s from 340° (NNW)

Pauwela
7.4ft @ 14s from 325° (NW)
2.9ft @ 10s from 345° (NNW)

NW swell filled in nicely, let's see how Pat Caldwell described the evolution of the fetches:
The first low pressure system tracked east from the Kuril Islands 12/4 with a ribbon of gales about 1800 nm out from Hawaii on the 310 degree great circle band by 12/6. The system weakened as it moved east of the Date Line 12/7. Addition short- to moderate- period swell was generated from marginal gales about 1000 nm N to NNW of Hawaii 12/7.
This event is predicted to peak overnight (Monday) above average and decline Tuesday as a new event arrives.
The next low pressure tracked eastward further north along 50N starting 12/6 reaching the Date Line late 12/7. Severe gales were the dominant wind with seas above 30 ft beyond 1500 nm away early 12/8 over the 315-335 degree band. This event should build locally mid Tuesday centered near 325 degrees, peak late Tuesday, then slow drop on Wednesday as yet a bigger episode fills in.

Below are the maps of Dec 4 through 8 which will help follow.


Below are the graphs of NW and Pauwela, together with yesterday's Surfline forecast. As you can see, the NW buoy peaked yesterday morning and then it had another bump in the evening. With a delay of about 18 hours, that should happen also today. In other words, plenty NW energy on tap all day on the north shore. Hookipa should be pretty solid in the morning with heights up to double overhead. Pipe contest on for sure.


Wind map at noon. There should be no wind until 10-11am.

North Pacific's strong NW fetch moved east and now is only partially aimed towards us (mostly to our east).


Nothing from the south.
