HIGH SURF ADVISORY FOR NORTH FACING SHORES

Swell Summary

The current northwest swell will remain steady through tonight. A large long-period northwest to north-northwest (320-330 degree) swell will quickly fill in late tonight through Wednesday and will likely exceed advisory thresholds through Thursday. A High Surf Advisory has been issued for north and west facing shores of Niihau, Kauai, Oahu, and Molokai and north facing shores of Maui from Wednesday morning through Thursday night. There is a chance that this swell could briefly approach warning thresholds late Wednesday night into Thursday morning.

A large storm force low is expected to develop across the West Central Pacific on Thursday and could send our first extra large northwest swell of the season into the islands from Saturday night into Sunday affecting exposed north and west facing shores. There are still some differences regarding the intensity of the low with each model run, but nonetheless we should see an extra large swell by next Sunday. Expect a higher degree of uncertainty on the final size of this next swell, as the size of the low and the close proximity of the fetch leaves some potential for even giant size surf affecting north and west facing shores by Sunday.

Surf along east facing shores will remain small through the week due to the lighter winds.
