Honolulu woke up warm and mostly clear this morning, sitting near 76°F at Daniel K. Inouye International Airport (PHNL), with highs expected to top out around 85°F on Sunday, July 5, 2026. East-northeast trade winds are on the upswing and will call the shots for beach and boating conditions through the holiday week, so anyone with outdoor plans will want to watch those gusts and the surf.
Afternoon Winds Pick Up
East-northeast trades are set to strengthen this afternoon, with sustained winds around 13 to 21 mph and gusts reaching about 30 to 31 mph through Sunday into Monday, July 6, 2026. Low clouds and brief showers will focus on windward and mountain areas, and localized MVFR conditions are possible at windward sites during the early morning hours. The National Weather Service Honolulu is flagging gusty conditions along exposed ridgelines and shorelines, along with the potential for moderate low-level turbulence over and downwind of terrain.
Showers Grow Tuesday, Heavier Late Week
Rain chances tick up a bit on Tuesday, July 7, 2026, as a weak easterly wave moves through and brings an increase in spotty showers. A stronger trough linked to the remnants of former Tropical Cyclone Douglas is forecast to pass by Thursday and Friday, July 9 to 10, 2026. Any heavier showers should favor windward mountain slopes and the late night to morning hours, while most leeward neighborhoods stay relatively dry.

Boaters And Beachgoers
Out on the water, things turn choppy. The Small Craft Advisory is expected to expand by mid-morning to cover all local Hawaiian waters, and small-boat operators are advised to steer clear of exposed channels and be ready for rough seas through Monday. A new long-period south-southwest swell will push south-shore surf toward High Surf Advisory thresholds Sunday into Monday, boosting rip-current and shore-break danger at popular south-facing beaches. Follow lifeguard instructions and offshore advisories from the National Weather Service Honolulu if you are heading out.
