Honolulu is waking up to a breezy but mostly dry Wednesday, with temperatures near 65°F early and highs headed for the upper 70s on Wednesday, April 1, 2026. Isolated rain showers are on the table for windward and mauka neighborhoods before noon, but most spots should see skies clearing out by the afternoon. East-northeast trade winds will be noticeable, with sustained speeds in the teens and gusts up to about 29 mph expected through the midday commute.
Afternoon Gusts to Watch
Through the afternoon, winds will generally blow from the east-northeast at roughly 10 to 21 mph, with stronger gusts in exposed locations. Drivers should be ready for sudden gusts on open stretches of road, and cyclists will want to take extra care on bridges and along Ala Moana Boulevard during peak winds. The trades are expected to ease as the week goes on, becoming lighter and more variable by the weekend.
Showers and Timing
Isolated showers are most likely before noon on Wednesday, mainly across windward slopes and upcountry areas. The odds are relatively low, at about a 15 to 25 percent chance for any given neighborhood. After midday, skies should trend mostly sunny, and the chance of measurable rain stays low for downtown and leeward neighborhoods.
Marine Conditions and Small Craft Advisory
A Small Craft Advisory remains in effect through 6 AM HST Thursday for windier waters around Maui County and the Big Island, so small-boat operators should exercise caution. The advisory and marine outlook come from the National Weather Service Honolulu.
This Week’s Outlook
Trade winds are forecast to diminish over the coming days, and some models hint at a front approaching early next week that could bring more organized showers. For background on the recent wet pattern and earlier watches issued in March, see our March coverage Kona Soaker Zeroes In On Honolulu.
Practical Tips
Carry a compact rain jacket for morning errands, secure loose outdoor items near the coast, and consider delaying nonessential small-boat trips while the advisory is in effect. If you have outdoor plans late Wednesday into Thursday, check the latest updates from the National Weather Service before heading out.
