4am significant buoy readings
2.4ft @ 14s from 194° (SSW)
South swell coming down a bit, while the new long period pulse is not really there yet. Let's see how Pat Caldwell describes the complex fetch evolution:
This final source over the 180-200 degree band had a long, wide fetch 5/17-20 with severe gales growing seas to near 30 feet. Those were weaker winds relative to the Mothers Day swell source near the same area, so this event is expected to be a notch lower locally. As with the Mothers Day event, and as is most often the case from the New Zealand source region, highest aim of seas and swell were off to the SE of Hawaii. This places higher error bars on the local surf estimate.
The PacIOOS/CDIP American Samoa buoy registered the rise of this event with 6 feet deep water swell at 15-17s building 5/22 and slowly dropping 5/23-24. These wave periods reflects the severe gale source. The Mothers Day source had winds to storm- force and the dominant period was longer.
Wave Watch III places the onset stage for the new event locally Saturday 5/25 centered from 190 degrees. Inconsistent sets above average are possible 5/25 PM.
The event should be filled in by Sunday 5/26 with a peak late in the day well above average. Slow change is expected with similar surf Monday morning followed by a downward trend into Tuesday from 180-200 degrees. Small surf from this direction should hold into Wednesday.

While it seems to be more like a Sunday arrival for this new pulse, there's still wonderful waves in the water from the previous fetches.
Here's a nice set at the harbor, check the webcam yourself before going.

The low that generated the current NW swell is still there making waves, this swell is going to be long lasting. Windswell fetch pretty solid too.
South Pacific taking a break.
