Honolulu is in for a mostly cloudy and breezy Saturday, June 27, with scattered rain showers drifting through and highs near 85°F. Persistent east-northeast trade winds will keep things feeling blustery, while overnight lows hold around 77–78°F. Windward and mauka neighborhoods will take the brunt of the wet weather, as many leeward spots stay relatively dry in between brief showers.
Afternoon Winds Pick Up
Through this afternoon, east-northeast winds of 13 to 20 mph with gusts up to 28 mph will make ridgelines and exposed shorelines feel especially choppy. Scattered showers are on the table, with chances around 25–30%, and most of those downpours should be quick hitters with new rainfall totals generally under a tenth of an inch, according to the National Weather Service.
Coastal And Marine Impacts
A Small Craft Advisory stays in place until 6 AM HST Sunday, June 28 for Oahu leeward waters, the Kaiwi Channel, Maui County windward and leeward waters (including Maalaea Bay and Pailolo Channel), the Alenuihaha Channel, and several Big Island coastal zones. For smaller vessels, that means it is a good night to favor sheltered harbors and be ready for choppy offshore conditions through the overnight. An earlier version of the advisory was issued on June 26, and forecasters have since extended the timing.
Looking Ahead
Forecasters expect bands of enhanced moisture to roll in late Sunday night and Monday, and again from Tuesday night through Wednesday night. That setup will bump up humidity and raise the odds of heavier showers, along with more spillover into typically drier leeward neighborhoods. Dewpoints are forecast to climb into the upper 60s to lower 70s starting Monday, which will make it feel noticeably muggy through midweek.
What To Do
If you are heading for the shoreline, give east-facing beaches extra space while the trades stay cranked up and make sure small watercraft are secured. For commuting and outdoor plans, a lightweight rain jacket is your friend, and it is smart to leave a little extra time for trips across windward areas. Before you launch the boat or hit the trail, check the latest marine and point forecasts so the weather does not surprise you.
