KAUAʻI, HI, USA — County emergency management officials have issued high-surf advisories and coastal flood watches following a series of robust north-northwest swells impacting the Hawaiian Islands.

High Surf and Coastal Hazards Impacting Hawaiian Shores

The powerful ocean conditions have generated hazardous breaking waves and dangerous rip currents along north- and west-facing shores across the state. Lifeguards and civil defense teams have stepped up patrols as large sets batter vulnerable coastal infrastructure and low-lying roads.

Safety Advisories and Forecast Details

Ocean safety authorities are urging residents and visitors to exercise extreme caution as the energetic swells continue to push ashore.

  • Hazardous Wave Heights: Surf along exposed north- and west-facing reefs is forecast to reach warning thresholds, creating treacherous conditions for swimming and ocean recreation.

  • Coastal Inundation Risk: Peak high tides combined with the heavy wave action raise the potential for localized coastal flooding, particularly along shoreline roadways and parking lots.

  • Beachgoer Safety: Officials strongly advise staying out of the water and remaining well away from rocky ledges and coastal shelves where unexpected rogue waves can sweep individuals into the sea.

Monitoring and Response

Local emergency services remain on high alert as the marine hazard persists through the weekend.

What to Expect Next

  • Extended Advisories: Forecasters expect high-surf conditions to gradually subside early next week as the swell direction shifts.

  • Public Updates: Emergency management will continue issuing real-time updates regarding road closures and beach safety conditions via local channels.
