Kauai Surf Forecast for November 13, 2022
A new long-period northwest swell will continue to build this morning and peak around mid-day. Buoy readings from buoy 51101 showed peak deep water swell heights of around 9 feet or so and 16 seconds around midnight. Since this is a little higher than previously expected, have decided to issue a High Surf Advisory (HSA) for north and west facing shores of Niihau and Kauai, as well as north facing shores of Oahu, Molokai, and Maui through this afternoon. This swell will decline through Monday. The next northwest swell is scheduled to arrive Tuesday with similar size, so HSA conditions are possible again along many north and west- facing exposures late Tuesday into Wednesday. This swell will be reinforced by a more northerly swell late Wednesday into Thursday.
The trade winds over and upstream of the islands are generating choppy, rough seas along east-facing shores. A small south- southwest swell will continue to provide small surf today, before declining. Another small south swell is possible during the second half of this week.
