Wednesday 4 29 20 morning call

Inspired by Marley (and the other tens of wingers at the harbor) I did session 6 (in 6 months) on the wing yesterday. I was waiting to do my trigger finger surgery before getting into that, but that was scheduled for March 30th and it obviously got cancelled. I learned that I need a board with proper foot straps placement.

5am significant buoy readings and discussion.
South shore
No southerly energy at the buoys, check the Lahaina webcam if interested, for size, conditions and consistency.

Little NNW bump is at the buoys, here's Pat Caldwell description of the evolution of the fetch.
A compact gale low formed near 40N just east of the Date Line early Sunday 4/26. By early Monday, the system had tracked over 1000 nm under the zonal jet, creating short-lived fetches over the 310-360 degree bands relative to Hawaii. ASCAT satellite 4/26 did show winds to severe gales within 36-42N as the system approached the longitudes of Hawaii. A JASON altimeter late 4/26 reading showed combined seas and swell over 20 feet. The highest seas were aimed NE of Hawaii. The head of the fetch of near gales was to 32N to the N to NNW of Hawaii, or about 600 nm, Sunday night.
Proximity ups the odds for some surf in Hawaii. The event should build Wednesday morning centered from 345 degrees, peak below the April average Wednesday PM, and drop steadily back to tiny to small levels by Thursday from 330-360 degrees.

Below is the map of the 27 (0h) that shows the fetch. As you can see most of the energy of this swell will miss us to our NE, but 3.7ft 13s from 340 will provide fun size waves (at least head high) at Hookipa. Beach report later.
