Update: Continued higher-than-normal water levels mean coastal flooding will persist

Updated at 12:33 p.m. Nov. 8, 2025: Peak monthly high tides combined with continued higher-than-predicted water levels will lead to minor coastal flooding persisting along shorelines and in low-lying coastal areas throughout the state.

Coastal flooding is most likely around the daily peak tide during the morning hours, especially at beaches that are normally dry. Shorelines and property along them, especially in low-laying areas and in places prone to flooding will likely also experience some minor coastal erosion and saltwater inundation.

National Weather Service forecasters in Honolulu say the threat of coastal flooding will now continue through Sunday morning and advise the public to take necessary precautions.
