Sunday 5 21 17 morning call

A lesson, a session and a work shift and another gorgeous day in paradise was filled with beauty. Took a while for my brain to register that presence.

4am significant buoy readings
South shore

2.6ft @ 13s from 195° (SSW)

2.5ft @ 13s from 188° (S)

2.6ft @ 13s from 163° (SSE)

Still some lovely southerly readings at the outer buoys, check the webcam. Yesterday it was consistently knee to waist high with occasional chest high sets on the Lahaina side. Today should be similar with a diminishing trend in the period.

North shore
3.3ft @ 8s from 69° (ENE)

Don't miss the opportunity to go look at Hookipa in one of the flattest days of the year. In summer time in fact, the trades blow pretty consistently and, unless they're very easterly, there's always a bit of windswell (for the joy of the Pavillions' aficionados). Today 3.3f 8s will be barely noticeable, instead.

No signs of the new NW swell at the NW buoys either, it will pick up during the night. Surfline calls for 5.5f 13s at 8am tomorrow, so there should be waves already at dawn. Here's their forecast (offshore swell tab, of course!).

Yesterday I forgot to comment about the wind and about how the new model I'm using was pretty spot on to predict the afternoon trades two days ago, while all the other models were calling for no wind. This is today's map at 2pm and it looks like I might be wind foiling again!

Current wind map shows:
- northerly fetch leftover from the NW fetch responsible for Monday's swell
- still a solid southerly fetch
The high pressure west of the north fetch will move east and bring us a temporary episode of trades, before another out of season lovely period of calm. That'll happen in coincidence with the arrival of the big south swell and the two things together are quite a rare occurance. I don't have the statistics, but I'd say it happens 1-2 times a year.

Automated generated fetches map. I could call it "computer circles", as opposed to my circles. As you can see, once again I overlooked the ESE little fetch.

And since that fetch east of New Zealand looks so good, here's the weather map that shows the lovely long parallel isobars. Tomorrow no more, but it was a pretty intense 3 days of wave generation for us.

Here, you can see everything I just wrote about the wind forecast on the Windguru 10 days table.

Morning sky looks pretty clear, but I heard of heavy rains yesterday afternoon in Kihei, so you never know how it's gonna end.
