Honolulu woke up early Wednesday, July 15, 2026, to mostly clear skies, a muggy 73°F at Daniel K. Inouye International Airport (HNL), and that familiar sticky trade-wind feel in the air. Moderate east-northeast trades are already shuttling quick, spotty showers onto windward coasts and up the mountain slopes, while leeward neighborhoods look to stay largely dry this afternoon.
Spotty Windward Showers Today
According to the National Weather Service, scattered showers will linger through Wednesday, with daytime highs near 86°F and overnight lows in the mid-to-upper 70s. Windward and mauka areas carry about a 30–40% chance of rain, and forecasters expect most showers to be brief, with new rainfall amounts generally under a tenth of an inch. If you are headed for windward beaches or higher terrain, a light rain jacket is still a smart accessory for those fast-moving downpours.
Winds, Small Boats And Surf
The National Weather Service notes that trades are moderate for now and coastal winds remain below Small Craft Advisory levels. However, winds could rebound from Thursday into the weekend, which would mean choppier conditions on the usual windy waters. A small bump in south-southwest swell, around 2.5 feet with a 13-second period, may give south-shore surf a slight lift this morning before it trends back down through the rest of the week. Mariners and small-boat operators should give the latest marine updates a look before heading out.
How This Affects Your Day
Expect quick, localized cutbacks in visibility on windward routes when a heavier shower rolls through, along with slick pavement in spots. Build in a few extra minutes for the commute and make sure outdoor furniture or tarps are tied down. Otherwise, the daily script does not change much through the weekend: warm afternoons near 86°F, muggy nights in the upper 70s, and those on-again, off-again trade showers focused on windward and mauka areas.
