A Coastal Flood Statement is in effect across all Hawaiian Islands, the National Weather Service in Honolulu said Friday.
Officials warned that higher-than-normal water levels, combined with incoming swells, could lead to isolated minor flooding in low-lying areas through early next week.
The advisory covers beaches, roads, docks, and boat ramps statewide. Even small surges can disrupt travel and affect property along exposed shorelines, authorities said.
“These conditions are typical for this time of year, but residents and visitors should remain cautious,” said meteorologist Keala Wong of the National Weather Service Honolulu office.
What the Coastal Flood Statement Means
The NWS issued the statement early Friday, tying the advisory to peak high tides and slightly elevated water levels.
Forecasters said isolated minor coastal flooding is possible near peak tides, especially overnight and in early mornings, through Monday afternoon.
Impacts could include wet beaches, minor erosion, and saltwater encroachment on low-lying roads and infrastructure.
“This is not a coastal flood warning, which would indicate more severe impacts,” Wong said. “But it is a reminder that even minor flooding can affect communities along the shore.”
Why the Flood Risk Is Higher Now
Forecasters point to two main factors: peak high tides and unusually strong northwest swells hitting exposed coastlines.
NWS noted that overlapping swells — one moderate to large and another longer period — are driving water levels higher than predicted.
“These combined factors can briefly flood areas that are normally dry,” Wong said. “It’s enough to cover sections of road or docks temporarily.”
Residents are familiar with the effects, especially during king tide events or when strong Pacific swells coincide with high tides.
Timeline of Expected Conditions
-
Friday: First northwest swell peaks overnight into early morning, raising water levels on north and west-facing shores.
-
Late Friday through Saturday: A second, larger swell will build, peaking along the same northwest coasts before weakening.
-
Through Monday: The Coastal Flood Statement remains in effect. Isolated flooding may occur near peak daily tides.
Forecasters warn that early morning high tides may be the most sensitive period, with water levels rising quickly in low-lying zones.
Official Guidance
The NWS urged residents and visitors to avoid driving through flooded roads and to move valuables and electronics to higher ground.
Boaters should monitor mooring lines and take care at boat ramps, where overwash could occur.
“There are no evacuation orders associated with this statement,” Wong said. “But simple precautions can prevent damage and ensure safety.”
Local Context and Public Response
Past minor flooding events have disrupted traffic and caused temporary closures. For example, South Kihei Road partially closed months ago after coastal flooding undermined a portion of the roadway.
Hawaii’s King Tides Project has documented similar events in prior years, showing how even minor surges can affect roads, parking areas, and beach access.
Community forums show residents discussing preparation tips, including moving vehicles away from flood-prone areas and checking forecasts daily.
What Happens Next
The Coastal Flood Statement will remain in effect through Monday unless conditions change.
Forecasters remind the public:
-
Flooding is most likely at peak tides.
-
Low-lying areas near shorelines are the most vulnerable.
-
Caution is advised when traveling along coastal roads.
After Monday, conditions may return to seasonal norms unless new swells or weather systems develop. Meteorologists will continue monitoring tides, water levels, and swell activity.

During daily peak high tides, especially early morning.
Should people avoid beaches now?
Not necessarily, but exercise caution near water during high tides.
Is this a coastal flood warning?
No. A statement indicates possible minor flooding; a warning indicates severe conditions.
Closing
Minor coastal flooding remains possible through Monday as elevated water levels and strong swells continue. Residents and visitors are encouraged to take simple precautions and monitor forecasts.
