(BIVN) – The National Weather Service in Honolulu has issued a High Surf Advisory for North and South Kona, which is in effect from midnight tonight to 6 p.m. HST Sunday.

Forecasters say a new, long-period west-northwest swell will begin to fill in tonight and is expected to peak during the day Sunday along west facing shores of the Big Island. The current northeast windswell will continue to gradually decline rest of this evening into tonight, and drop below advisory levels by Sunday.

Surf will rise to 5 to 8 feet tonight, climbing to 6 to 9 feet Sunday along west facing shores.

“Expect strong breaking waves and strong currents making swimming dangerous,” the National Weather Service stated Saturday afternoon. “Heed all advice from ocean safety officials and exercise caution.”
