South-facing shores of Kaua‘i to be under high surf advisory beginning Saturday night

National Weather Service forecasters in Honolulu issued a high surf advisory from 6 p.m. Saturday, June 13, through 6 a.m. Tuesday, June 16, as a long-period south-southwest swell is expected to build in throughout the island chain tonight.

Surf of 8 to 12 feet is expected by late Saturday night and 10 to 14 feet by Sunday afternoon, June 14, through Monday night, June 15.

Impacts are expected to be moderate to high, with strong breaking waves and strong currents making swimming dangerous along the advisory shores.

The combination of the incoming south-southwest swell and King Tides during the next couple of days will also result in more widespread coastal shore impacts, particularly during the afternoon and evening peak daily tide.

The public is advised to heed all advice from ocean safety officials — when in doubt, don’t go out.

A long-period south-southwest swell will build tonight and peak Sunday night into Monday before gradually declining through the rest of the week.

South and west shorelines will be impacted by the resulting surf, with south shores reaching advisory level heights.

Surf heights could also approach warning levels along south-facing shores and advisory levels for west-facing shores during the peak of this event.

The combination of the swell, King Tides and the daily high tide will make low-lying coastal areas along south and west shores susceptible to more widespread coastal flooding.
