Mostly clear skies and a muggy 77°F greeted early risers at Daniel K. Inouye International Airport as of 4:53 a.m. HST Wednesday, with east‑northeast trade winds starting to kick into a higher gear across Oʻahu. Those trades will carry scattered, fast‑moving showers through the day, favoring windward and mauka neighborhoods with brief, light bursts of rain.
What to Expect
Daytime highs are expected to land near 85°F, with overnight lows holding in the upper 70s. East‑northeast winds should run about 10–21 mph, with gusts pushing up to roughly 29 mph. Showers are most likely in the morning and overnight hours, and most spots should pick up less than a tenth of an inch from any one passing shower, according to the National Weather Service Honolulu.
Marine And Surf
Small boat operators will want to take note: a Small Craft Advisory is in effect for the typically windier channels and several coastal waters into early Thursday morning, as choppy conditions build in. A south swell will also continue to fill in through Wednesday night and is expected to peak on Thursday. Exposed south‑facing breaks should see the largest sets, so beachgoers and boaters are urged to check local harbor and lifeguard advisories before heading out.
How This Affects Your Day
A light rain layer is a smart grab for morning errands, especially if you are cutting through windward or mauka areas. Allow a little extra time on routes where gusty crosswinds can nudge high‑profile vehicles around. If you have offshore plans and your vessel is on the smaller side, it may be worth reconsidering until conditions ease.
