Honolulu is waking up breezy and bright at Daniel K. Inouye International Airport early Sunday, March 29, 2026, with mostly clear skies, about 69°F on the observation, and northeast trade winds already blowing a steady 20 to 25 mph. Gusts into the 30s will make it feel cooler than the thermometer reads, with a high near 76°F and only spotty windward showers expected overnight.
Small Craft Advisory and Harbor Surges
A Small Craft Advisory is posted for most coastal waters from 6 AM HST Sunday, March 29, 2026, through 6 AM HST Monday, March 30, 2026, with seas up to 11 feet and northeast winds up to 25 knots, according to the National Weather Service. The forecast discussion also calls for a north-northeast swell to build through the afternoon, along with a Marine Weather Statement for harbor surges in Hilo and Kahului tonight into Monday that could produce breaking waves at harbor entrances. Boaters are urged to avoid exposed launches and secure vessels now, per the National Weather Service.
Afternoon Gusts Could Affect Driving And Outdoor Plans
Trade wind gusts into the low to mid 30s mph are likely through at least Tuesday, March 31, 2026, especially along windward shorelines and on exposed ridgelines. Those stronger bursts can make steering high profile vehicles tricky and send unsecured outdoor furniture tumbling, so bring in loose items, delay rooftop work, and budget extra time for commutes on open stretches of road.
Surf And Beach Safety
The building north-northeast swell may push surf on north and east facing shores toward advisory levels tonight, Sunday, March 29, 2026, creating strong shorebreaks. Beachgoers should heed lifeguard and harbor notices, stay well back from breaking waves, and avoid launching small craft while advisories are in place.
Forecasters expect the trade wind pattern to ease by midweek, with lighter and more variable winds arriving by Friday and into the weekend. Check National Weather Service Honolulu updates and local harbor bulletins before heading out for any marine or coastal activities.
