Thursday 1 18 18 morning call

Two shortboard and a windsurf sessions for me yesterday. Session two was at Honolua, here's some photos.

Meanwhile, at Hookipa the conditions were quite radical with big waves and very strong wind. Casey Hauser found a diamond in the rough in this photo by Jimmie Hepp from this gallery.

4am significant buoy readings
South shore

No indication of southerly energy at the buoys, the Surfline forecast calls for 0.6f 15s starting at 2pm and very slowly increasing throughout the next few days.

North shore
6.4ft @ 12s from 330° (NW)

6.7ft @ 13s from 319° (NW)

8.1ft @ 13s from 327° (NW)
6.7ft @ 8s from 72° (ENE)
2.6ft @ 6s from 75° (ENE)
2.4ft @ 9s from 339° (NNW)
The NW swell peaked yesterday afternoon as predicted, now it's on its way down, but 8f 13s at 4am is still a solid couple of numbers. Below are the graphs of NW101, Pauwela and the Surfline forecast. Notice how the black line stayed almost steady after the peak of the ground swell at the NW buoy. That's because it indicates the significant wave height, which is the result of all the energies present in the water (more precisely, it's the average of the highest one-third of all of the wave heights during the 20-minute sampling period). That's an information of very little interest, unless your spot is open to all the directions, like a buoy.

Underneath the black line, there's the individually sorted swell events and that's what you want to know in order to correctly make your call.
Check the forecast now. Today the NW ground swell (red line) is predicted to go down quite quickly, while the easterly windswell (purple line) is on the rise. 
The resulting height of the waves at your spot(s) of interest is part of the local knowledge that each surfer should have.

Wind map at noon shows strong easterly trades.

North Pacific shows a WNW and a NW fetches and a windswell one.

South Pacific doesn't show anything of relevance.

Morning sky.
