High surf closes four West Hawaii beach parks, threatens Kona coast

A long-period south-southwest swell slammed the Kona coast Wednesday, shutting down Kahaluu Beach Park, Laaloa Beach Park, Old Kona Airport Beach Park and Kohanaiki Beach Park as surf climbed to 10 to 14 feet and dangerous currents pushed into shoreline areas that are usually dry.

The closures hit some of West Hawaii’s busiest recreation spots, where families, swimmers, surfers and beachgoers head for the water year-round. Hawaii County Parks and Recreation kept the parks closed because the surf and runup made the shoreline unsafe, and officials said reopening would depend on the swell easing, currents weakening and surf dropping below the National Weather Service advisory threshold for south-facing shores, which is 10 feet in full-face height.

The danger was not limited to the waterline. Powerful wave runup and strong currents made even exposed shoreline areas hazardous, especially during afternoon high tides. Motorists along the Kona coast were warned to expect periodic wave wash across places that normally stay clear, a reminder that a surf event can turn into a road and access problem in a matter of hours.

The National Weather Service Honolulu Forecast Office said the south-southwest swell would gradually decline Thursday, fall below advisory levels by Friday, and fade further through Sunday, with another pulse arriving late Sunday into early next week. That forecast meant the county’s closures could remain in place until conditions became safer for the public and for shoreline responders.

The impact spread well beyond the beach parks. Surf slammed seawalls along Alii Drive, drenched passers-by and vehicles, and helped force the Pride of America cruise ship to skip its Kona stop. A concert by the Kona and Windward Oahu choral societies was also canceled because of the dangerous surf, showing how one offshore swell can ripple through transportation, tourism, recreation and arts plans across Kailua-Kona.

County officials have taken the same approach before, including a January 31 beach-closure notice that warned dangerous currents from high surf could cause injury or death. Hawaii County and the Hawaii Department of Land and Natural Resources have often mirrored each other’s West Hawaii closures during hazardous surf, a pattern rooted in the county’s shoreline guidance that summer brings higher surf to south and east shores. In Kona, that seasonal reality can shut down some of the island’s most used shoreline parks in a single afternoon.
