Honolulu is set for a bright but breezy Sunday, with temperatures climbing from around 79°F early to near 86°F this afternoon. East-northeast trade winds of 14 to 18 mph will gust as high as 25 mph, making exposed areas feel more active than the sunny forecast suggests.

Rain should stay limited through the afternoon, with just a 10% chance of precipitation in the current forecast. The pattern changes after sunset, when scattered showers may move in and continue into Monday, especially across windward and mauka neighborhoods.

Trade Winds Stay The Main Story

The NWS Honolulu expects breezy trades to continue through the week, with showers generally favoring windward and mauka areas while many leeward spots remain mostly dry during daytime hours. Monday looks mostly sunny but carries a 40% chance of scattered showers, with winds increasing to 20 to 24 mph and gusts up to 28 mph.

Tuesday and Wednesday should remain warm, with highs around 86 to 87°F and passing showers possible. Trades may ease slightly Tuesday night into Wednesday before strengthening again later in the week.

Late-Week Winds Could Pack More Punch

Thursday brings mostly sunny skies, isolated showers and gusts up to 31 mph, while Friday could be the breeziest day in the near-term forecast, with winds around 26 mph and gusts reaching 38 mph. Scattered showers remain possible Friday and Saturday, with rain chances around 40% on both days.

The weather service is also watching Tropical Storm Lowell far southeast of Hawaii. NWS Honolulu says the storm’s track and strength remain uncertain and that it is too early to predict specific impacts, though windier weather is increasingly likely toward the end of the week; the National Hurricane Center is providing the storm’s latest official updates.

Boaters Face Rougher Conditions

A Small Craft Advisory remains in effect until 6 p.m. Sunday for several Oahu waters, including windward and leeward zones and nearby channels. Anyone heading out should check the latest marine conditions before departing, especially as trade winds build.

For most Honolulu residents, the practical forecast is simple: sunny and hot Sunday afternoon, a few showers overnight, and a notably windier stretch from Monday into Friday. Leeward neighborhoods may stay mostly dry, but umbrellas could be useful in windward and mauka areas.
