Hookipa yesterday morning.

Later in afternoon, photo from Jimmie Hepp's album of the day. You can notice the increment in size.

4am significant buoy readings and discussion.

The medium period pulse of this series of swells picked up yesterday afternoon as predicted. Today we see signs of the new XL long period swells at the buoys, but we won't really see much of it today, other than some sets at sunset. Here's how Pat Caldwell described the evolution of the fetch (timing is for Oahu):

A new low-pressure system is rapidly deepening Friday morning 12/4 near 42N, 170E. Models show continued deepening to near 950 mb, or hurricane-force, as the center moves east to near 170W overnight Friday. The east movement of the center at about the same speed as the growing longer period swell will allow a captured fetch over the 315-325 degree band into Saturday with upper-end gales reaching within 1000 nm. Proximity spells size with a rapid surf increase for Sunday PM on Oahu. Timing for the onset and magnitude can be fine-tuned with the NW Hawaii NOAA buoy readings overnight Saturday night to Sunday morning. The event should climb to extra-large levels by late afternoon Sunday 12/6, peak overnight, and slowly drop though remain extra-large on Monday 12/7.

Below is the collage of the maps of December 4 through 6 that will help follow the above description.

Almost 7ft 13 at Waimea makes me call for well overhead waves at Hookipa to start the day with. Those medium period waves should stay remain pretty steady all day and that will make spotting the sets of the new long period one more difficult. At 20s it takes 12 hours for the energy to get from the NW buoy to us, so the equivalent of those 2ft 20s registered by NW101 should be here around 4pm.
An increase in the possible overall size of the waves is hence possible at sunset. Tomorrow, big waves at Jaws and Honolua again, while Hookipa will be too big to surf.
