Wednesday 1 17 18 morning call

Just a windfoiling session (actually a lesson) for me yesterday. This photo by Jimmie Hepp from this gallery shows pretty radical conditions at Hookipa in the afternoon.

4am significant buoy readings
South shore
No indication of southerly energy at the buoys, the Surfline forecast calls for 0.5f 11s.

North shore
11.6ft @ 13s from 338° (NNW)

8ft @ 13s from 325° (NW)

4.9ft @ 13s from 313° (NW)

5.4ft @ 13s from 332° (NNW)
3.9ft @ 11s from 335° (NNW)
2ft @ 5s from 63° (ENE)
1.7ft @ 7s from 18° (NNE)

New NW pulse on a steep rise (close by fetch) at the NW101 buoy as shown in the graph below. Applying GP's rule of thumb for the travelling time (16h @ 16s +/- 1h/1s), at 13s a swell takes 19h to get here, so I drew a red dotted line to indicate the rise of the swell in Maui. It will be more visible in the afternoon and biggest by sunset. The morning will still have plenty energy (5.4f 13s at 4am) from the previous one. The problem, as usual, will be the wind already blowing 13mph at Hookipa at 6am.

Better get used to it, since we're about to get slammed by some strong trades for the next few days, as the Windguru table shows.

Wind map at noon shows moderate/strong trades.

North Pacific shows a distant NW fetch, a closer but weaker NNW one and a tiny, but pretty intense NE one. Multiple swells are hence going to overlap in the second part of the week.

South Pacific shows the rest of the Tasman Sea fetch we saw the past few days. The southerly one dissipated.

Morning sky.
