Honolulu woke up Tuesday, March 31, 2026, to a partly cloudy start and about 71°F at Daniel K. Inouye International Airport, with brisk northeast trades already roughing up surf along east-facing beaches. A few isolated morning showers might sneak through, but most neighborhoods are expected to stay dry as highs climb into the upper 70s.
Afternoon Winds Pick Up
Northeast winds are forecast to ramp up to 18 to 23 mph this afternoon, with gusts reaching up to 32 mph in more exposed areas, so it will feel windier than the numbers alone suggest. The National Weather Service Honolulu notes that today could be the windiest day of the week and says some wind-prone channels and ridgelines may briefly approach advisory levels. Bicyclists, walkers and anyone spending time on open ridges should secure loose items and be ready for sudden gusts, especially near channels.
Marine And Beach Conditions
A Small Craft Advisory remains in effect for local waters through 6 p.m. HST, so boaters and paddlers should be prepared for choppy seas and gusty onshore winds. The National Weather Service Honolulu suggests postponing recreational trips if possible and tying down loose gear. East-facing shores will take the brunt of the rough conditions, and swimmers and surf users should watch for stronger currents and short, steep waves near more exposed points.
Showers And Weekend Outlook
Rain chances stay on the low side, around 20 percent, with any showers expected to be brief and isolated, favoring windward and mauka slopes. Most of Honolulu should remain dry. A drier airmass is working in and trades are forecast to ease to light and variable by the weekend, which should make outdoor plans a bit more comfortable.

Plan Ahead
If you are heading out, a light windbreaker will come in handy for shoreline walks, and it is a good day to lock down patio umbrellas or any loose yard items. Drivers on more exposed stretches, especially those in high-profile vehicles, should allow extra time in case of gusty crosswinds. Anyone planning to launch a small boat should double-check the latest marine advisories and harbor updates before leaving the dock.
