(BIVN) – The National Weather Service in Honolulu has issued a High Surf Advisory for Hawaiʻi Island, as surf along south-facing shores will be on the rise today.

A large south-southwest swell is filling in across the state, forecasters say. Wave heights will be 7 to 10 feet this morning, and then peaking at 10 to 14 feet late this afternoon and tonight, then lowering to 7 to 10 feet Wednesday. The swell is expected to gradually subside through the rest of the week.

Forecasters say we can expect “ocean water occasionally sweeping across portions of beaches, very strong breaking waves, and strong currents. Breaking waves may occasionally impact harbors making navigating the harbor channels dangerous.”

Hawaiʻi County Civil Defense says there are no beach closures at this time, but “beaches may be closed without notice.”

“We will continue to monitor observations closely as the swell builds, in case a High Surf Warning might be required during the peak of this event late today and tonight,” the National Weather Service wrote in discussion. “There is the potential that advisory level surf could hold into the day Thursday.”
