Tuesday 10 13 20 morning call

Fun waves on the south shore yesterday.

4am significant buoy readings and discussion.
South shore

3.1ft @ 13s from 209° (SSW)
0.8ft @ 18s from 192° (SSW)

2.9ft @ 13s from 196° (SSW)

New 18s energy at Barbers indicates the slow start of a new long lasting swell. Below are the maps of Oct 6 through 10. As often, most of the energy will directed towards the Americas, so we'll see how much angular spreading we get.

Meanwhile, 3ft 13s from the previous swell (see fetches collage posted yesterday) would be as good as it gets for many Lahaina side spots. Unfortunately the buoys don't tell the whole story, and the Lahaina webcam shows very low consistency at the moment. Might increase with the rising tide. Ideally you want to have both, but webcams better than buoys, always.

North shore
4.2ft @ 11s from 356° (N)

2.6ft @ 12s from 327° (NW)

2.6ft @ 11s from 27° (NNE)

2.9ft @ 12s from 15° (NNE)

The surrounding buoys suggest a couple of feet 12s also locally, which means waves up to head high at Hookipa.

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).
