Honolulu woke up Monday morning, May 11, 2026, to muggy air in the mid-70s at Daniel K. Inouye International Airport, with a few stubborn trade-wind showers sliding across windward Oʻahu. Those passing showers should stay most common overnight and in the early morning, then step aside for mostly sunny afternoons with highs around 83 to 84°F on Monday, May 11. Trades will be breezy enough to rattle umbrellas and kick up gusts along ridgelines, so plan on gusty afternoon conditions in exposed spots.
Afternoon Winds Pick Up
Northeast winds are expected to run about 12 to 18 mph on Monday, May 11, then trend up to roughly 15 to 21 mph by Tuesday and Wednesday, May 12 to 13, with gusts reaching into the mid 20s mph. That should make afternoons feel noticeably breezy across Waikiki, the Ewa Plain and central Oʻahu, and could leave some east-facing beaches with choppier surf. These wind and temperature details line up with the National Weather Service forecast from NWS Honolulu.
Showers Favor Windward Areas
Showers will continue to favor windward and mauka slopes, with isolated early-morning downpours possible on Monday, May 11, and scattered showers most nights as the week goes on. After a soggy stretch earlier this month, the trades are settling in and overall rainfall is expected to ease through midweek and into next weekend. When showers do move through, new rainfall amounts should stay light for most neighborhoods, generally under a tenth of an inch per event.
Marine Interests
A Small Craft Advisory is posted through 6 AM HST Tuesday, May 12, 2026, for Maalaea Bay, the Pailolo and Alenuihaha channels, and nearby Big Island coastal waters. Northeast winds of 15 to 25 knots and choppy seas will make conditions hazardous for small vessels. Inexperienced mariners should skip open-water runs for now and touch base with local harbormasters before heading out. More details are available in the National Weather Service marine bulletin from NWS marine message.
What To Bring
For windward beaches or early-morning hikes, pack a light rain jacket, then trade it for sunscreen once the sun breaks out in the afternoon. Secure lightweight outdoor items ahead of the breezier hours so they do not go flying. If you were planning a casual boating trip, it is safer to postpone nonessential outings until after the Small Craft Advisory expires early Tuesday, May 12, 2026.
