UPDATE: Coastal flood statement to carry over another day, through Sunday morning

Update at 9:32 a.m. Dec. 6, 2025: A threat of minor coastal flooding will continue through today and and Sunday morning (Dec. 7) as monthly tides rise higher than predicted.

Brief periods of minor flooding are forecast along shorelines and in low-lying areas of the state during the early morning peak high tide.

Vulnerable low-lying coastal roadways, docks, boat ramps and other coastal infrastructure could see impacts from coastal flooding. Beaches that are normally dry also could be briefly inundated and coastal erosion is possible.

Forecasters remind the public:

• Avoid driving through flooded roadways.
• If you are forced to drive through salt water, be sure to rinse your vehicle with fresh water as soon as possible.
• 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.

Members of the public are encouraged to submit their coastal flooding photos to the University of Hawaiʻi Sea Grant College Program Hawaiʻi and Pacific Islands King Tides Project.

Original story posted at 4:12 p.m. Dec. 3, 2025: National Weather Service forecasters in Honolulu issued a coastal flood statement for all of the islands, in effect from midnight Thursday, Dec. 4, through Saturday, Dec. 6.

Peak monthly high tides combined with water levels higher than predicted will lead to minor flooding along shoreline and in low-lying coastal areas.

Coastal flooding will be especially possible by about daily peak high tide, which will be during the early morning hours.

Isolated minor coastal flooding is expected, with vulnerable low-lying coastal roadways, docks, boat ramps and other coastal infrastructure especially at risk.

Flooding of normally-dry beaches, minor coastal erosion and saltwater inundation also are possible. 

Forecasters advise the public:

• Avoid driving through flooded roadways. If you are forced to drive through salt water, be sure to rinse your vehicle with fresh water as soon as possible.
• 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.
