Thursday 11 26 20 morning call

Relatively small day at Hookipa yesterday, this photo is from this album by Jimmie Hepp.


4am significant buoy readings and discussion.
South shore
Barbers
1ft @ 18s from 213° (SW)

That foot 18s at Barbers is highly suspicious, as there were no fetches whatsoever that could justify it, so check the Lahaina webcam if interested, for size, conditions and consistency.

North shore
NW001
3.7ft @ 12s from 349° (NNW)

Waimea
4.1ft @ 14s from 341° (NNW)

Mokapu
4.7ft @ 9s from 74° (ENE)

New NW pulse should be on the rise all morning and peak in the afternoon. Here's Pat Caldwell description of the evolution of the fetch:
A low-pressure system raced NE from the central NW Pacific to the Gulf of Alaska 11/21-23. Highest seas were not over the quadrant aimed at Hawaii, which had only lower end gales that stayed beyond 1500 nm away. NW Hawaii NOAA buoys 51001 and 51101 11/25 AM show low energy filling in for the 13-15 second band. This event should be near its peak by Thursday morning at levels well below the seasonal average out of 320-340 degrees with short swell periods of 10-14 seconds. There could be some addition longer period energy of 14-18s though of lower height out of 340-360 degrees, via angular spreading from the hurricane-force winds that formed just east of the Hawaii swell window 11/23. This should not make breakers any higher than the shorter-period swell. Both should trend down into Friday morning from 320-360 degrees.

Below are the maps of Nov 22 and 23 that will help follow the above description.

It might be well below the seasonal average, but 4ft 14s should still be better than what we had in the last few days. With the easterly windswell on the slow decline, NW might actually be the dominant energy in the water today. I expect Hookipa to be overhead, but without Pauwela that is really hard to guess. I'll beach report later.

With the exception of the first week, November really has been well below the season average, but I just say three big NW swells back to back during the whole first half of December on Windy.
