Saturday 7 31 21 morning call

No photos from yesterday. OneMoreFoto posted this photo of Matt Meola from last winter. He said it was three feet. Ah, the lovely hawaiian scale...

5am Surfline significant buoy readings and discussion.
South shore

3ft @ 8s from 172° (S)
1.2ft @ 12s from 230° (SW)
1.2ft @ 15s from 191° (SSW)

Small but long period energy at Barbers (Lanai is offline). Here's a paragraph from Pat Caldwell's latest forecast:
NOAA southern buoy 51002 Friday 7/30 shows an uptick in the 15-17 second wave energy starting ~7 AM HST. That should up the ante a notch for the dusk patrol surfers. There were a string of fast-moving, compact low-pressure systems moving east along 55S to the S to SE of New Zealand 7/21-24. Highest seas were aimed at the Americas. It appears the last in the series had the best surf potential for Hawaii since it acted upon existing seas of similar direction. This event should be short-lived. It should peak on Saturday below to near average.

That would be good news for the Hi-Tech organized Ole Longboard Classic contest at Launiupoko (today and tomorrow). Unfortunately, the webcam shows long period of flatness, only very occasionally interrupted by decent long period sets like this. Better than nothing, I guess. Check the Lahaina webcam if interested, for size, conditions and consistency.

North shore

4.6ft @ 8s from 82° (E)
3.8ft @ 7s from 76° (ENE)

Strong easterly trades are predicted till Wednesday. The windswell will consequently be increasing, but the direction is going to be pretty easterly, so Hookipa won't pick it up much. Home guess for it is flat to waist high at Pavils. Bigger on eastern exposures.
