Honolulu is staying warm and mostly sunny Wednesday, with temperatures near 79 degrees early in the day and an afternoon high around 87. East-northeast trade winds will make it feel noticeably breezy, blowing near 18 mph with gusts up to 25 mph. For now, it is a beach-and-errands kind of day, but the forecast gets more complicated by the weekend.
Sunny Skies Hold Through Thursday
Wednesday night should remain mostly clear, with a low near 76 and isolated rain showers possible after midnight. Thursday looks sunny again with another high near 87, while northeast winds strengthen to 13 to 21 mph and could gust as high as 29 mph, according to the National Weather Service Honolulu.
Friday starts with a small chance of showers before noon, followed by mostly sunny skies and another high around 87. Winds could reach 22 mph with gusts up to 31 mph, and the combination of dry air and stronger trades may push fire-weather concerns close to critical levels.
Weekend Forecast Takes A Tropical Turn
Rain chances rise Friday night, with scattered showers and a 50% chance of precipitation. Saturday brings a 70% chance of rain showers, mostly cloudy skies and possible tropical-storm conditions by Saturday night, with similar conditions possible Sunday.
Forecasters are monitoring a tropical disturbance known as 93C about 900 miles east-southeast of the Big Island. The system has a high chance of developing, but its eventual track and strength remain uncertain, so Honolulu residents and visitors should keep checking updates at hurricanes.gov.
Potential impacts include stronger winds, periods of heavy rain and rough surf. East- and southeast-facing slopes could see the heaviest rainfall, and persistent downpours may cause flash flooding or quickly rising streams, while the Big Island and Maui County currently appear to have the highest rainfall potential.
Surf And Boating Conditions Could Get Rough
South-facing shores are already seeing elevated surf, with waves expected to reach High Surf Advisory levels Thursday. East-facing shores will remain rough from the trades, and warning-level surf of 15 feet or higher is possible into the weekend if the tropical system develops as expected.
Outdoor plans look relatively straightforward through Thursday, but Saturday and Sunday may require more flexibility. Mariners should check the latest marine forecast, and residents should secure loose outdoor items before the weekend system gets closer.
