Saturday 1 11 20 morning call

Well, yesterday I did look for a decent place to surf and took the camera out trying to shoot something decent, but I failed at both tasks, so here's a shot of Desert Point which I saved a while ago and forgot to write down the source.

4am significant buoy readings and discussion
South shore
No indication of southerly energy at the buoys, check the Lahaina webcam if interested.

North shore
12.4ft @ 10s from 96° (E)
8.8ft @ 14s from 327° (NW)

7.5ft @ 17s from 311° (NW)

10.3ft @ 11s from 70° (ENE)
4.7ft @ 14s from 330° (NW)
2.8ft @ 4s from 70° (ENE)
2.7ft @ 18s from 319° (NW)
New NW swell(s) on the rise, here's how Pat Caldwell described the evolution of the fetches:
A low pressure near 40N, 170E moved west 1/5-6. The PacIOOS/CDIP Waimea, Oahu near shore buoy shows this energy Friday 1/10 in the 14-16s band. This event should be short-lived as a new event takes over 1/10 PM.
A low pressure gained storm-force as it tracked ESE from the Kuril Islands 1/6-7. Seas grew over 30 feet over the 305-315 degree band relative to Hawaii in an area about 2000 nm away from Hawaii. The low weakened rapidly 1/8 as it was forced northward by the jet level ridge. A secondary low pressure moved east from Hokkaido 1/6 and merged with the Kurils low 1/7. The secondary low had a fetch of gales to severe gales over the 290-305 degree band. The dominant swell is expected from the former though the secondary low should add lower, more westerly-component surf.
Can't show you the fetch maps, as the first one I posted upon my return was the 8th, we'll just trust uncle Pat. Below is the graph of Waimea, which is the only one that shows clearly the two pulses of the NW energy (red circles), the other buoys are just too hammered by the ENE energy. As you can see, there was a clear bump up over night which will translate into a similar one locally this morning.

Let's look at Pauwela now:
10.3ft @ 11s from 70° (ENE) is the strong ENE windswell
4.7ft @ 14s from 330° (NW) is the energy from the first fetch described by Caldwell
2.7ft @ 18s from 319° (NW) is the energy from the second, much stronger fetch described by Caldwell: much longer period and likely climbing up around 6ft 16s during the day.
In other words, plenty of energy to play with, unfortunately the problem will be the strong wind again.

Wind map at noon

Kahului Tides
High Tide     High Tide     Low Tide     Low Tide       Sunrise   Sunset
3:35a  +2.9   2:21p  +1.3  10:14a  +0.7   8:43p  -0.6    7:07a   6:04p    

Once again, it's mostly about the windswell fetch today.

That nice fetch deep in the Tasman Sea is still there.

Morning sky.
