Honolulu woke up Friday, June 5, to warm, muggy air and partly cloudy skies, with an overnight low near 746°F ahead of a high close to 846°F. East-northeast trade winds are already kicking up along exposed shorelines and ridgelines, and gusts in the upper 20s could rattle any loose items left outside. Most showers will favor windward slopes and mountain neighborhoods, with only a few brief sprinkles sneaking into leeward spots.
Afternoon Winds and Showers
Moderate to fresh east-northeast trades of 14 to 618 mph, with gusts up to about 25 mph, are expected through the weekend and into the first half of next week. Those winds will steer the bulk of the showers into windward and mauka areas, mainly overnight and in the early morning hours. A Small Craft Advisory remains up for Maalaea Bay, the Pailolo and Alenuihaha Channels, and several Big Island nearshore waters through 6 p.m. HST Saturday, June 6, and forecasters say that advisory may need to be extended into early next week. A small south-southwest swell near 3 feet at a 14-second period will keep south-facing surf just above seasonal levels, with another small long-period south swell expected late Sunday and peaking Monday, according to NWS Honolulu.
Marine And Surf
Small-boat operators should stick to more sheltered harbors and skip exposed channel crossings while the advisory is in place, since inexperienced mariners are especially at risk. East-facing beaches will stay on the choppy side thanks to the trades, while south shores remain elevated but still below high-surf advisory criteria for now. If the late-Sunday swell shows up as forecast, expect another bump in surf on south breaks Monday.
Practical Tips
Secure patio furniture and any loose yard gear before the gusty afternoons kick in, and watch for blustery crosswinds on coastal commutes. If you are headed out early in windward or mauka neighborhoods, toss a light rain jacket in the car, because the showers are quick but can be briefly heavy.
