Friday 11 13 20 morning call

Photo of the day goes to the beautiful Danielle.

4am significant buoy readings and discussion.
South shore
1.5ft @ 12s from 187° (S)


1.2ft @ 15s from 197° (SSW)
0.8ft @ 12s from 191° (SSW)

Small long period SSW energy at the buoys. Check the Lahaina webcam if interested, for size, conditions and consistency. Unfortunately, there's not much at all.

North shore
3.5ft @ 17s from 330° (NW)

2.8ft @ 17s from 271° (W)

0.8ft @ 20s from 309° (WNW)

6.9ft @ 9s from 67° (ENE)

8ft @ 9s from 73° (ENE)

While the easterly energy continues to be pretty elevated, a new long period WNW swell will slowly be on the rise all day. The two NW buoys indicate very different directions, let's have a look at where the fetch was to determine which one is more correct. Below is the collage of the maps of Nov 9 to 11 that shows the fetch starting NE of Japan. Pretty westerly and very distant, I would not expect this swell to hit any spots on Maui's north shore other than Hookipa.

Below is the Surfline forecast that calls for only 3ft 15s tomorrow. My guess is that in the afternoon there will be inconsistent sets at Hookipa. In the morning, it's still going to be all about the easterly windswell. Probably still head high at Hookipa and overhead on the eastern exposures.

Wind map at noon .The other ones can be found at link n.-2 of GP's meteo websites list in the right column (click on animation of the 10 meter column).

Fetches map (circles legend: red: direct aim, blue: angular spreading, black: blocked, yellow: apparent direct aim, but out of the great circle ray map, so not 100% sure).
North Pacific (about 4 days travel time from the NW corner of the North Pacific):
