Tuesday 10 2 18 morning call

A SUP foiling and a windfoiling session for me yesterday. This shot from Jimmie Hepp from this gallery shows that there were still solid waves at Hookipa.


4am significant buoy readings
South shore
W
2.4ft @ 17s from 278° (W)

2.3ft @ 13s from 199° (SSW)

 

SW
2ft @ 13s from 145° (SE)

1.8ft @ 17s from 146° (SE)

 

SE
1.7ft @ 18s from 168° (SSE)

 

Barbers

1.4ft @ 13s from 200° (SSW)

 

Lanai

1.5ft @ 14s from 205° (SSW)

1.3ft @ 18s from 220° (SW)

 

New long period and old medium period energies at the buoys, it should be another fun day on the south shore. Yesterday Thousand Peaks was waist high and delightful.

 

North shore
NW101
8.3ft @ 15s from 314° (NW)

Hanalei
5.9ft @ 17s from 305° (WNW)

 

Pauwela

3.8ft @ 9s from 357° (N)                        

1.4ft @ 18s from 313° (NW)

 

Uho-ho! 8f 15s smells like winter to me and that's what's hitting the NW buoy. Below are the graphs of NW and Pauwela together with the Surfline forecast (link n. 15). As indicated in the reference post Buoys to Maui travel times and Maui's shadow lines (it's in the labels section, but I have a dedicated bookmark for it in my browser), GP's rule of thumb for calculating the travel time from the NW buoy to Maui is:
16h at 16s (+1h -1s and viceversa for different periods)

 

I put two red arrows on the NW buoy's graph to indicate that the swell went from 2 to 6 feet from around 11am to 5pm yesterday. We can expect a similar rise during the day today and that's what I drew on Pauwela's graph. That'll be  a little earlier than what predicted by Surfline. We shall see.

 

Below is the wind map at noon.

But look how nice and glassy the morning should be at least until 9am.

 

North Pacific keeps having a lot of lows, but not many fetches oriented towards us.

 

South Pacific going zonal, not a good thing for us.

 

Morning sky.
