(BIVN) – The National Weather Service has issued a High Surf Advisory for south, east, and north facing shores of Hawaiʻi Island until Monday.

Surf heights of 6 to 9 feet are expected tonight, rising to 8 to 12 feet Sunday through Monday afternoon.

According to the weather advisory issued on Saturday afternoon:

An energetic south swell will boost surf heights above advisory threshold along south facing shores. Forerunners have already arrived, and surf will continue to rise tonight into Sunday before declining late Monday.

“Coastal residents should secure their property from possible effects of high surf,” a Hawaiʻi County Civil Defense message stated. “Beach-goers should limit or postpone shoreline activity.”

“Beachgoers, swimmers, and surfers should heed all advice given by ocean safety officials and exercise caution,” the National Weather Service said. “Boaters should expect recreational surfers and body boarders utilizing harbor channels to access surfing areas.”
