Honolulu heads into Monday, March 30, 2026, mostly sunny and comfortable, with a forecast high near 78°F and nighttime lows in the upper 60s. Steady northeast trade winds will keep air moving and could kick up gusts along exposed ridges and channels, while isolated showers stay focused on windward and mauka zones. Expect a breezy ride for the daytime commute, with winds trending lighter and more variable as the weekend approaches.
Afternoon Winds Pick Up
Northeast winds should run about 15 to 21 mph Monday, with gusts potentially reaching 29 mph in the usual wind-prone spots. Trades are expected to stay in the moderate to locally breezy range through Tuesday before easing by midweek, and a few ridges could briefly flirt with advisory-level criteria, according to the National Weather Service.
Showers And Temperatures
Rain chances sit around 20 percent and are mainly reserved for windward slopes in the overnight and early morning hours, so most neighborhoods should see dry, pleasant conditions during the day. High temperatures will hold in the upper 70s through early next week, with gently cool nights settling into the upper 60s.
Coastal Hazards And Boating
A High Surf Advisory and Small Craft Advisory remain posted through 6 PM HST Monday for many north and east facing shores. A Marine Weather Statement also flags harbor surges, especially at Hilo and Kahului Harbors, meaning elevated surf and choppy conditions at exposed harbor entrances, per the National Weather Service. Small boats are better off staying in sheltered waters, and beachgoers should steer clear of wet rocks and harbor ramps until seas settle down.
What To Do Today
Tie down or bring in loose outdoor items, put off nonessential water trips, and give high profile vehicles extra space on gusty roadways. Check in with local harbor and lifeguard advisories before heading to the shore, and keep an eye on official updates if you have coastal plans tonight.
