Honolulu is waking up to mostly clear skies and warm air this morning, with the airport thermometer hovering near 77°F and a steady push of east-northeast trade winds. Brief, scattered rain showers are expected to swing through off and on through midweek, mainly over windward and mauka neighborhoods, with only spotty spillover to leeward spots. In other words, this is a light-rain-jacket-by-the-door kind of week, especially for afternoon commutes and outdoor plans.
Tuesday will stay warm and breezy with a high near 86°F and east-northeast winds of 12–16 mph, gusting up to around 22 mph. Scattered showers remain in play through the day, with precipitation chances near 40 percent and most areas seeing less than a tenth of an inch where showers do develop, according to the National Weather Service Honolulu.
Afternoon Winds Pick Up
Trade winds are expected to crank up a notch into midweek, making afternoons feel noticeably breezier along exposed shorelines and ridgelines. Wednesday is lining up as the windiest day, with east-northeast winds of 15–21 mph and gusts that could reach 29 mph, so it is a good time to secure umbrellas, beach tents, and any other loose gear before you head out.
Marine And Surf
Stronger trades, combined with a passing upper-level disturbance, could push conditions near Small Craft Advisory levels for windier waters and channels near Maui and the Big Island beginning Wednesday, so mariners should keep an eye on updates. A moderate, long-period south swell will build into Wednesday night and peak Thursday, bringing head-high to overhead surf to exposed south-facing breaks, along with higher surf on east-facing shores through the period. The forecast discussion from the local office highlights these trends and urges extra caution for small craft and exposed beaches, as outlined in the National Weather Service.
What To Expect This Week
Moisture should peak through Wednesday, keeping shower chances highest for windward and mauka areas, with only isolated heavier bursts expected. Drier air slides in later in the week, so those scattered afternoon showers should taper off by Friday and Saturday, and weekend plans are looking sunnier.
If you are headed outside, a windproof rain layer and some time spent tying down loose items are smart moves. Boaters and surfers should check the latest marine forecasts before launching. No active warnings were in effect for Oahu at the time of this update, but conditions can change quickly, so check the National Weather Service page before you travel or head out on the water.
