Wednesday 10 7 20 morning call

Awesome waves on the south shore yesterday.

Kai Lenny just released the latest episode of his 20@20 series. I think that was Sept 24, here's the link to the post I did the day after.

I spotted four tiny mini fins by the tail.

4am significant buoy readings and discussion.
South shore
2.8ft @ 14s from 198° (SSW)

2.7ft @ 15s from 185° (S)

Great numbers at the buoys, should be another really good day on the south shore. Check the Lahaina webcam if interested, for size, conditions and consistency.

North shore
7.1ft @ 10s from 336° (NNW)

3.1ft @ 13s from 86° (E)

3.5ft @ 13s from 84° (E)

Pauwela is offline this morning. Mokapu and Hilo show that the energy from the ex hurricane Maria is about 3ft 13s. That should make for some fun size waves on the eastern exposures, but flat at hookipa. Remember, buoys don't tell the consistency.

Below is the graph of NW101 that shows that a new medium period NNW swell rose from 2 to 7 feet from 6pm to midnight. GP's rule of thumb (16h@16s +/- 1h per 1s) says 20h at 12s, so a similar rise (minus the loss of energy for extra travel distance) should start around 2pm locally. I doubt there will be much to be noticed at that time, but there should definitely be some waves on the north shore by sunset.

Below are the maps of Oct 3, 4 and 5 that show the wide but weak (hence the not so high period) fetch that generated this swell. I made sure to include Maria, so you guys can also see where the easterly energy comes from. Way smaller fetch, but much more intense winds in it.

Wind map at noon (the other ones can be found at link n.-2 of GP's meteo websites list in the right 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):

South Pacific (about 7 days travel time from east/west of New Zealand):

Morning sky.
