High Surf Advisory
Issued: 1:49 PM Nov. 11, 2025 – National Weather Service
...HIGH SURF ADVISORY REMAINS IN EFFECT UNTIL 6 PM HST THIS EVENING... * WHAT...Along north facing shores, surf of 12 to 18 feet this morning, decreasing to 10 to 15 feet by this afternoon. Along east facing shores, surf of 8 to 12 feet this morning, increasing to 10 to 14 feet by this afternoon. * WHERE...North and east facing shores of Niihau, Kauai, Oahu, Molokai, Maui, and the Big Island. * WHEN...Until 6 PM HST this evening, though this advisory will need to be extended through at least Wednesday night for east facing shores. Coastal flooding impacts are likely around and during the morning high tide cycles. * IMPACTS...High. A combination of higher than predicted water levels, large breaking waves, and strong onshore winds could lead to significant wave runup, beach erosion, and localized coastal flooding. Waves may wash across areas of the beach that typically remain dry, with potential overwash onto vulnerable low-lying coastal roadways and properties. PRECAUTIONARY/PREPAREDNESS ACTIONS... Heed all advice from ocean safety officials. Avoid driving through flooded roadways. If you are forced to drive through salt water, be sure to rinse your vehicle with fresh water. Move electronics, vehicles or other valuables to higher ground. Monitor vessels to ensure mooring lines don't get too tight and watch out for overwash around boat ramps. Secure canoes or other watercraft stowed on beaches. &&
Marine Weather Statement
Issued: 1:15 PM Nov. 11, 2025 – National Weather Service
A north-northeast (020 to 030 degrees) swell of 8 to 9 feet at 13 seconds will generate surges in north facing harbors today, mainly at Hilo and Kahului, as well as breaking waves near the harbor entrances. Mariners using these harbors should exercise caution when entering or leaving port and when mooring or launching vessels. The swell will remain elevated Wednesday and Thursday, but the swell direction will shift out of the northeast, which will reduce the threat of surges.
