Small long period energy recorded by Lanai, but there's not much in the water. Check the Lahaina webcam if interested, for size, conditions and consistency.

New long period WNW swell rose at the NW buoys (notice the 295 direction) and will be on the rise all day locally. In the water there's also shorter period energy from NNW/N. Below are the maps of January 25 through 29 that show the fetches that generated them: black arrow for the long period westerly one and red arrow for the much closer generated short period northerly. While I was at it, I also indicated with blue arrow another fetch that is responsible for a smaller NW swell (4ft 16s) that will arrive Wednesday.


Below is the Surfline forecast that shows a peak tonight at 7ft 16s for the WNW swell. The northerly one is covered by it in the graph, but it's predicted around 6.5ft 10s for both days.

Distantly generated long period westerly swell and closely generated short period north swell are as different as it gets in terms of consistency and power of the sets. Here in Maui, the first one will have extremely low consistency, while the second will have waves pretty much constantly breaking. Home guess for Hookipa is around head and a half and stormy mostly due to the latter, with occasional much cleaner sets from the former filling in more often as the day goes.
Pipeline will receive much more WSW energy than Maui, but I'm afraid the north one will sneak in there too and make conditions not ideal, also because of the NE winds. This is the youtube streaming link for the WSL contest (first of the season) starting today.
8am update: the contest is called off.

Wind map at noon. The other ones can be found here.
