High surf advisory issued for western shores of Big Island as two swells build down island chain

Forecasters at the National Weather Service office in Honolulu issued a high surf advisory in effect until 6 p.m. Friday (Jan. 30) for west shorelines of the Big Island as two significant northwest swells build down the island chain. High surf advisory conditions for exposed west-facing shores are the main concern with the first swell’s arrival. The peak of the second swell, however, is forecast to push surf heights possibly above warning levels late Friday through Saturday for some shorelines. Additionally, a combination of surf and high-than-expected water levels will produce nuisance coastal flooding throughout the state — including the Big Island.
