Honolulu starts Wednesday, May 13, 2026 mostly clear and sitting near a comfortable 75°F, with steady east-northeast trade winds in the 13 to 20 mph range and gusts pushing up to about 28 mph. A few isolated morning showers are in the mix for windward and mountain spots before skies turn mostly sunny and temperatures climb to around 83°F.
Afternoon Gusts Target Ridges And Shorelines
Those east-northeast trades will stay breezy through Thursday, May 14, 2026, and the most exposed ridgelines and shorelines will take the brunt of it. Gusts are most likely in the afternoon and early evening, so anything light or unsecured on lanais, decks or in yards is fair game to get tossed around. Beachgoers, cyclists and drivers of lighter vehicles should be ready for sudden gusts along exposed stretches of road.
Showers, Surf And Tides On The Move
Isolated showers are possible this morning, but the atmosphere looks set to get a bit more interesting as a mid- to upper-level low tracks over the islands Friday, May 15, 2026 into the weekend. That feature could pull additional moisture north, which would raise the odds of scattered, and at times heavy, showers.
On the water, a Small Craft Advisory is in effect until 6 PM HST Thursday, May 14, 2026 for zones that include the Kaiwi Channel and several Maui County coastal waters. A northwest swell building today will bump up surf along north-facing shores through Thursday. At the same time, monthly high tidal levels are expected to reach about 2.5 to 3.0 feet MLLW by Saturday, May 16, 2026, which could bring overwash into low-lying coastal areas during high tide, according to the National Weather Service Honolulu.
Plan Ahead Before You Head Out
If you are planning time on the water this week, tie down or stow small craft securely and check in with harbor offices or lifeguards for the latest conditions before you launch. On land, factor in gusty winds and the potential for brief heavy showers Friday into the weekend when making outdoor plans.
