Monday 9 30 19 morning call

Still fun waves yesterday in Lahaina, but this is Paige Alms at Hookipa in the swell that hit a couple of days ago. Photo by onemorefoto.

This instead is the biggest wave from yesterday that I've seen in Jimmie Hepp's daily gallery of the windsurfing action.

3am significant buoy readings and discussion
South shore
2.2ft @ 11s from 197° (SSW)
1.4ft @ 15s from 191° (SSW)
1.4ft @ 9s from 201° (SSW)

1.7ft @ 15s from 181° (S)
1.6ft @ 13s from 193° (SSW)
1.6ft @ 10s from 190° (S)

Mix of periods at the buoys, but with 1.7ft 15s at Lanai, I'm going also today. Couldn't find its fetch, but it's better like this than the other way around (fetch and no swell). You guys check the webcam before going (when the sun is out).

North shore
1.6ft @ 15s from 319° (NW)

1ft @ 16s from 308° (WNW)

4ft @ 9s from 53° (ENE)

New long period small NW swell arrived at the local buoys, there should be decent waves at Hookipa. Below are the maps of September 26 and 27. On them you can see three fetches:
1) A moderate fetch in that position will generate a swell that takes about 4 days to get to Hawaii
2) this one is associated with a much closer low, so its swell only took a couple of days and was much bigger (it arrived Friday/Saturday)
3) the windswell fetch has been on for many days, so the NE energy has been continuously arriving (4ft 9s at Mokapu).

So why do I go to Lahaina nonetheless someone may wonder? Because I can, and the waves are much cleaner.

Wind map at noon.

North Pacific only has the windswell fetch.

Moderate fetch (30 knots) in the Tasman Sea will make for a good size swell for Fiji in 2-3 days and a small in Hawaii one in a week.
