A high surf advisory is in effect until 6 a.m. Saturday, Sept. 25, the National Weather Service in Honolulu announced this morning.
According to NWS, buoy observations indicated that a new long-period north-northwest swell is larger than initially expected, and will bring high surf to exposed north and west-facing shores on Kauaʻi. The swell will build down the island chain today, then gradually lower overnight tonight.
Surf heights are expected to be 12 to 16 feet high.
Impacts are anticipated to be moderate. Beachgoers should expect strong breaking waves, shore breaks and strong longshore and rip currents making swimming difficult and dangerous.
Beachgoers, swimmers, and surfers should heed all advice given by ocean safety officials and exercise caution. Know your limits and seek ocean recreation areas best suited for your abilities.
When in doubt, don’t go out.
