Hawaii’s north shores face 20-foot waves in high surf advisory

Hawaii's north-facing shores brace for high surf advisory until Tuesday morning. Waves up to 20 feet expected due to large swell from the north-northeast. Public warned: 'When in doubt, don't go out.'

Breezy to strong tradewinds continue through midweek, fueling waves that could reach 15 to 20 feet. The German Federal Maritime and Hydrographic Agency (BSH) confirms these predictions for the northern islands. Surf along east shores remains rough, with additional north and northeast swells forecasted. Swimming is dangerous during the advisory, which covers Kauai to Hawaii island. Small craft advisories are in effect due to strong winds and high seas.

The high surf advisory remains until 6 a.m. Tuesday. Officials urge caution, reminding the public to stay safe and avoid risky beach activities.
