Two significant northwest swells are expected to impact the state over the next several days. The first moderate to large long period northwest swell will build down the island chain today. This swell will produce High Surf Advisory (HSA) conditions today for north and west facing shores of Niihau, Kauai and Oahu. A bigger, overlapping, long period northwest swell will build in on Friday. This swell will swiftly exceed warning levels Friday through Saturday for the same northwest islands, expect the HSA to expand in coverage to the islands of Molokai, Maui and west facing shores of the Big Island by Friday. This swell will then decline early next week before an extra large northwest swell arrives next Tuesday onward.
Surf along east and south facing shores will remain small.
