Honolulu started off the Memorial Day weekend on Saturday, May 23, 2026, with a classic trade-wind setup: breezy east-northeast winds, mid-70s at daybreak, and a high expected near 82°F. Light, spotty showers are favoring windward and mauka neighborhoods early, while most leeward spots are lining up for a sunnier afternoon. Sustained east-northeast winds around 18 to 22 mph, with gusts near 30 to 31 mph, will make it feel a bit windier than the thermometer alone would suggest.
Morning Showers, Mostly Sunny Afternoons
Scattered showers are most likely through the morning hours before tapering off, with skies trending to mostly sunny by mid-afternoon. New rainfall totals should stay under about a tenth of an inch. Highs will hover near 82°F, with humidity easing back later in the day, according to the National Weather Service.
Afternoon Gusts Could Matter
Those trades are expected to stay breezy through the holiday weekend, with east-northeast winds typically in the 18 to 22 mph range and gusts up to around 31 mph in more exposed spots. That is enough to jostle high-profile vehicles and send unsecured outdoor items tumbling. Local reporting notes a Wind Advisory was extended over parts of the east end of the state, so drivers and hikers can expect extra-blustery stretches near ridgelines and channel crossings, per Hawaii News Now.
Marine Conditions
On the water, a Small Craft Advisory is in effect through early Sunday morning, with east-northeast winds near 20 to 25 knots and seas running about 5 to 7 feet. Smaller vessels will be more comfortable sticking to sheltered harbors and postponing open-ocean runs until conditions back off a bit, per the National Weather Service.
Memorial Day Outlook
Memorial Day on Monday, May 25, 2026, is shaping up much the same: a few isolated morning showers, then mostly sunny skies with a high near 82°F. East-northeast winds around 20 mph, with gusts pushing into the upper 20s, will keep things on the breezy side. Beachgoers can expect choppy water along east-facing shores and should stay tuned to harbor and surf updates before jumping in.
Quick tips for the long weekend: tie down or bring in loose patio and lanai furniture, give high-profile vehicles extra room on exposed roadways, and mariners should double-check harbor notices before launching.
