NNW Expected to Build, High Surf Advisory Likely Later Today
By Meteorologist Malika Dudley / Email: [email protected]
The National Weather Service has extended the High Surf Advisory for the west side of Molokaʻi and the north shores of both Maui and Molokaʻi until Friday at 6 a.m.
A reinforcing north northwest swell is expected to arrive later today, once again pushing surf heights to the high surf advisory criteria along most north and west facing shores of the smaller Hawaiian islands. This elevated surf will likely continue through Friday.

North: Surf is expected to ease today as our current northwest begins to fade. Still, waves could be up to 18 foot faces at the best breaks exposed to the swell. Late in the day a new north-northwest swell will start to build in keeping surf heights steady.
West: Breaks that don’t catch the swells are forecasted to get smaller surf at ankle high or flat. Spots that are open to the north-northwest swell will get some wrap with waves expected overhead at the best breaks early in the day.
South: Ankle-slappers to flat surf conditions are expected.
Mahalo to former Super Typhoon Nuri for generating an exciting swell the last couple of days. (To see our slideshow of Peʻahi Jaws images click here) The current northwest swell (315-335°) is expected to slowly fade today. The west side is shadowed from the swell and will be smaller but will still catch a wrap at the best exposed breaks.
A new north-northwest swell (325-350°) is right on its heels, expected to elevate surf above the high surf advisory threshold later today and through Friday. The swell will show best along the west side of Molokaʻi and the north shores of Maui and Molokaʻi. Lānaʻi is heavily shadowed and the west side of Maui is partially shadowed. We’re looking at double overhead surf at the best breaks, maybe bigger on the sets. Saturday the swell will start to fade. That trend is expected to continue through Sunday.
Super small trace amounts of swell expected out of the SPAC. There isn’t much on the horizon out of the South Pacific.
Keep in mind, surf heights are measured on the face of the wave from trough to crest. Heights vary from beach to beach, and at the same beach, from break to break.
