Honolulu wakes up Saturday, July 11, 2026, to breezy, muggy trade-wind weather that is sticking around a bit longer than many would like. Daytime highs will reach about 86°F, with overnight lows holding in the mid-70s around 76–77°F. East-northeast trades will run in the mid-teens to low-20s mph, with gusts up to about 29 mph and scattered windward showers that could turn into quick downpours.
This update builds on the coverage that first flagged gusty trades and spotty showers on July 9. Forecasters are now leaning into an extended Small Craft Advisory for offshore waters and paying closer attention to the timing of King Tides early next week.
Forecast Through The Weekend
Saturday, July 11 will be partly sunny with a high near 86°F, east-northeast winds of 15–21 mph, gusts up to 29 mph, and about a 30% chance of showers during the day. By Saturday night into Sunday morning, the chance of showers increases to roughly 50%, with most rain brief and light, and new amounts generally under a tenth of an inch. According to National Weather Service Honolulu, highs will stay in the mid-80s through the week with on-and-off trade-wind showers.
Marine And Coastal Impacts
A Small Craft Advisory is in effect for Hawaiian waters through 6 PM HST on Sunday, which means choppy conditions on east-facing shores and tricky launching for small boats. Higher-than-normal high tides, including King Tides from Monday through Wednesday, could bring nuisance coastal flooding to low-lying streets and boat ramps. Shoreline residents and mariners should secure gear and move valuables to higher ground while the water runs high.
What To Do
If you have plans on the water, consider delaying launches until conditions ease and check local marine forecasts and tide charts before heading out. On land, use extra caution driving near the shoreline during high tide windows and watch for brief heavy downpours that can quickly cut visibility. We will update readers promptly if advisories change.
