Honolulu is waking up to a mostly clear, warm Memorial Day on Monday, May 25, 2026, with temperatures near 73°F and a steady east-northeast trade wind making it feel breezier than the thermometer shows. Isolated morning showers are expected for windward and mauka spots, followed by mostly sunny skies and a daytime high near 82°F.
Afternoon Winds Pick Up
By afternoon, those east-northeast trades will be holding steady around 16 to 21 mph, with gusts pushing into the upper 20s and low 30s, especially along exposed ridgelines and channel crossings. That is enough to jostle loose patio furniture and buffet high-profile vehicles, so securing outdoor items and giving extra space to taller vehicles on cross-wind stretches is a smart move, according to Hawaii News Now.
Showers And Marine Outlook
Isolated showers remain most likely before noon over windward areas, with new rainfall generally under a tenth of an inch. Skies should trend mostly sunny later in the day, and tonight's low will settle near 73°F.
On the water, Small Craft Advisories are still in effect for many exposed channels and coastal waters through this evening and into Tuesday, and a long-period south-southwest swell is expected to build late this week and peak into the weekend. Mariners and beachgoers are urged to check harbor conditions and surf updates before heading out, according to the National Weather Service Honolulu.
Plan Ahead
If you are driving on exposed roads, allow extra time for gusty crosswinds and keep an eye on windward skies for any quick passing showers. Anyone planning time on the water or at more exposed beaches should double-check the latest marine forecasts and advisories before committing to the day. Updates will be posted if advisories or surf watches change.
