Hawaiʻi County Closes Kahaluʻu Beach Park May 1–10 for Coral Spawning

The Hawaiʻi County Department of Parks and Recreation will temporarily close Kahaluʻu Beach Park in Kailua‑Kona from May 1 through May 10, 2026 to protect the annual spawning cycle of cauliflower coral, Pocillopora meandrina, county officials announced. The closure applies to public access for swimming, snorkeling, and surfing in Kahaluʻu Bay; the county and media reports state the park will fully reopen on May 11.

Cauliflower coral along the North Kona shoreline experienced severe losses during 2010s marine heatwaves that caused widespread bleaching and wiped out most of the species in the bay, Hawaii News Now reported. Annual rest periods established in 2018 are credited with boosting recovery; HNN noted that recent efforts to regenerate the species have led to more spawning, with “thousands of juvenile corals” observed in recent years.

Hawaii County Mayor Kimo Alameda underscored the local stewardship rationale in remarks published by Hawaii News Now: “Kahaluu is home to a unique and vital near‑shore coral reef ecosystem that requires careful stewardship,” said Hawaii County Mayor Kimo Alameda. “By taking time to let this special place rest, we can do our part to ensure its recovery and protection for future generations.” The mayor’s statement frames the closure as a management action aimed at increasing reproductive success for the bay’s reef system.

The county advisory specifically asks Kahaluʻu visitors to refrain from entering the water during the May 1–10 period and to wait until the park fully reopens on May 11. Local education partner Kahaluʻu Education Center (KBEC) promotes reef etiquette at the site and remains a focal point for outreach about protecting juvenile corals and honu that frequent the bay.

Kahaluʻu Beach Park sits in Keauhou just south of Historic Kailua Village, roughly 5 miles south of the Kailua‑Kona town center, and is a popular, sheltered snorkeling spot with parking, lifeguards, bathrooms, outdoor showers, and a large covered picnic pavilion with BBQs. Love Big Island and GoHawaii note the bay’s cultural significance: the area has been populated for at least the last 500 years, contains several heiaus, and is listed on the National Register of Historic Places; Kuʻemanu Heiau overlooks a north‑bay surf break.

The county press materials name the Parks and Recreation department as the source of the closure but do not specify enforcement measures, exact geographic boundary lines within Kahaluʻu Beach Park, or which research teams documented the “thousands” of juvenile corals, leaving those operational and scientific details open for follow up. Visitors planning trips during early May are advised to consult current ocean‑safety monitors and posted hazard notices before traveling and to observe on‑site signage and KBEC guidance when the park reopens.
