UPDATE: High surf advisory extended for north, east shorelines of Big Island

Update at 3:30 a.m. Feb. 25, 2025: The high surf advisory for north and east shorelines of the Big Island has been extended until 6 p.m. today.

National Weather Service forecasters in Honolulu expect surf of 15 to 20 feet through the morning along north-facing shores, dropping to 12 to 16 feet this afternoon.

For east-facing shores, surf of 10 to 14 feet is forecast through this morning, then falling to 8 to 12 feet by this afternoon.

Strong breaking waves and strong currents along those shorelines will continue to make swimming and other ocean activities dangerous.

The public is advised to heed all advice from ocean safety officials. When in doubt, don’t go out.

Meanwhile, the high surf advisory that was in place for west-facing shores of the Big Island was canceled. Forecasters in Honolulu report that surf along those shorelines fell below advisory level.

Update at 4 p.m. Feb. 24: A high surf advisory has been extended until Wednesday morning for Big Island shorelines.

The National Weather Service expanded a high surf advisory to include west-facing shores, along with north and east-facing shores of the Big Island until 6 a.m. Wednesday morning. All high surf warnings have been canceled.

A long period north-northeast swell peaked early this morning, producing much larger than normal surf across some coastlines, which caused the closure of all Hilo beach parks. The swell will gradually decline late this afternoon through Friday.

The expected surf heights on Big Island shorelines are:

• North-facing shores: 18 to 24 feet this evening, dropping to 15 to 20 feet;
• East-facing shores: 12 to 16 feet this evening, dropping to
  10 to 14 feet;
• West-facing shores: 6 to 8 feet.

Update at 8:04 a.m. Feb. 24: Several beaches in North Hilo are closed due to high surf and debris along northeast-facing shores.

Hawai‘i County’s Parks and Recreation Department has closed Kolekole Beach Park as well as all the beach parks in Hilo from Bayfront to Richardson Ocean Park.

They will remain closed all day.

Original post at 12 a.m. Feb. 24: Surf reaches 12 to 18 feet overnight on east-facing shores, prompting Bayfront Highway to close in Hilo until further notice.

The Hawaiʻi Police Department advises motorists to avoid Bayfront Highway between Waiānuenue Avenue and Pauahi Street due to large waves and debris on the road. Use an alternative route until further notice.

A high surf warning was issued for north- and east-facing shores of the Big Island through 6 p.m. Tuesday. The swell is expected to gradually decline Tuesday night through Friday.
