Honolulu is waking up mostly clear and warm on Thursday, July 9, 2026, with a high near 86°F and east-northeast trade winds already filling in across the island. Showers are lining up for windward and mauka areas, while most leeward neighborhoods look to stay largely dry. Out on the water, a Small Craft Advisory is posted through Friday, July 10 at 6 p.m. HST.
Afternoon Trades Crank Up
East-northeast trade winds will be running in the teens, with gusts pushing into the mid 20s and higher along exposed ridges and through channels. Expect choppy conditions along east-facing shores and gusty runs through the valleys, which can make life tricky for high-profile vehicles and cyclists and will turn local waters rough. According to the National Weather Service Honolulu, the Small Craft Advisory is in effect for all Hawaiian coastal waters through 6 p.m. HST Friday, July 10.
Spotty Showers And Sticky Air
A surge of tropical moisture will funnel most of the heavier showers onto windward and mauka slopes, keeping leeward spots mostly dry. Overnight into early Friday, there is about a 60% chance of spotty showers, with most passing quickly and dropping under a tenth of an inch of new rain. Isolated totals could reach a few tenths of an inch Friday night into Saturday. Dewpoints will climb into the low 70s, so evenings and mornings will feel noticeably muggy.
King Tides Eye Low-Lying Shores
Higher than normal high tides, including King Tides, are possible starting in the latter half of the weekend, with the first peak expected Sunday, July 12. Low-lying coastal streets, boat ramps and docks could see nuisance flooding around the late-afternoon high tides. Mariners and shoreline residents are urged to secure small craft and move valuables to higher ground until tides ease. Tide timings and heights are posted at NOAA Tides & Currents, and our background on the sticky trades and earlier advisories has more context on the setup.
Plan outdoor time for late morning or early afternoon, when showers are least likely, and steer clear of flooded streets if water starts to rise. If you have waterfront plans, check marine forecasts and tide charts before heading out and consider postponing launches while the advisory remains in effect. We will update this story if the National Weather Service issues any new advisories.
