Monday 9 6 21 morning call

Went winging up the coast with Jason Hall yesterday and here's a little video he made of the sesh.


4am Surfline significant buoy readings and discussion.
South shore
Barbers

2.3ft @ 10s from 167° (SSE)
1.8ft @ 6s from 159° (SSE)
1.5ft @ 13s from 190° (S)
1.1ft @ 16s from 184° (S)

New small long period swell should be on the rise today (might be that 16s energy). This is how Pat Cadlwell described the fetch:
The second event had a gale source S to SE of New Zealand 8/28-29. Winds were mostly middle gales, though there were small pockets to severe gales. The fetch was broad and had direct aim at Hawaii. The limiting factors are the long travel distance (> 4200 nm) and the weaker source winds, which place the dominant wave period into a shorter bracket (14-16 seconds). This source is very similar to the source that produced the swell locally last weekend 8/28-30, which took about 8-9 days to travel here from its source. Given that long travel time, the onset is due on Monday 9/6, with the event filled in by Tuesday from 180-195 degrees. It should peak a notch above average Tuesday 9/7 then slowly decline 9/8 from 175-185 degrees of shorter wave periods (less juice) of 10-12 seconds.

Below are the maps of August 28 through 31 that will help follow. The fetch looks decent on the 29 and 30, so I expect the next couple of days to have decent waves. Bit slow today, better Tuesday and Wednesday.


Check the Lahaina webcam if interested, for size, conditions and consistency.



North shore
Pauwela 5am

3.5ft @ 8s from 65° (ENE)
1.3ft @ 11s from 89° (E)

Windswell trending down, home guess for Hookipa is around waist high.
