Skies are mostly clear over Daniel K. Inouye International Airport this morning, with the thermometer hovering near 74°F and the air on the muggy side. East‑northeast trade winds are already on the move and will keep scattered showers focused on windward and mauka neighborhoods through Thursday, with highs near 82°F and overnight lows around 72–73°F. Expect some brief downpours to sweep through, but most spots should only pick up light totals.
Afternoon Winds Pick Up
By this afternoon, trades are expected to strengthen, with sustained east‑northeast winds generally in the mid‑teens to low‑20s (mph) and gusts near 30–31 mph in exposed areas. Those gusts can make life a little tricky for high‑profile vehicles and kick up extra spray along east‑facing beaches. The National Weather Service Honolulu says this trade‑wind pattern will hang around for several days, so the gusty feel is likely to carry right into the weekend. National Weather Service Honolulu
Scattered Showers Through The Weekend
Showers will continue to favor windward slopes and mauka zones, with occasional spillover into leeward neighborhoods. Day‑to‑day rain chances sit in the 30–40 percent range. New rainfall amounts are expected to be light, generally under a quarter inch, though short, heavier bursts can pop up in the stronger cells. A compact rain jacket or umbrella is still a smart grab‑and‑go item, and drivers should be ready for slick patches during passing showers. National Weather Service Honolulu
Marine And Surf
A Small Craft Advisory is posted for Kahoolawe and for channels and windier waters around Maui and the Big Island through 6 p.m. HST Friday, May 1, 2026, so small‑boat operators will want to favor more sheltered harbors while the advisory is up. Forecasters also expect a moderate, longer‑period northwest swell to arrive late Friday into Saturday, nudging north and west‑facing surf above average, though still below advisory levels for now. Local reporting earlier today highlights the same breezy trade pattern and marine concerns.
Planning Tips
For commuters and anyone with outdoor plans, it is worth building in a few extra minutes if you will be driving along exposed stretches of road and keeping a light rain layer handy for those pop‑up showers. Boaters should check harbor and nearshore conditions before launching and avoid exposed launches while the Small Craft Advisory remains in effect. It is also a good idea to keep an eye on updated forecasts before locking in weekend plans, since periods of windward showers are expected to persist even as the upper‑level disturbance gradually drifts to the northeast.
