Moderate to breezy trade winds will continue in Honolulu through the week, with a Small Craft Advisory in effect until Sunday morning, particularly affecting boaters around Maui County and south of the Big Island. A cold front is expected to bring cooler weather on Sunday but will weaken and stall before reaching Kauai, leading to slightly lower wind speeds. The National Weather Service also predicts an increase in showers for the first half of next week, especially in higher elevations and windward areas, while leeward areas are likely to stay drier, according to the National Weather Service.
The National Weather Service outlook shows a high-pressure ridge influencing the weather, with stable clouds moving across the region and trade winds bringing occasional showers, mostly on windward areas. Balloon soundings in Lihue and Hilo show inversion heights of 5,100 and 6,300 feet, keeping showers mainly uphill. Flight conditions are expected to be mostly stable, with moderate to breezy trade winds, brief low cloud ceilings, and showers possibly reducing visibility in mountainous areas. An AIRMET Tango alert for turbulence below 7,000 feet is in effect, meaning pilots may experience some turbulence but flights should continue without major issues.
A north-northwest swell is peaking today, bringing near head-high waves before it recedes over the weekend. Smaller swells are expected next week, keeping surf conditions around seasonal norms. A south-southwest swell is producing "fun above summer average surf heights," but it will decrease by next week. Small swells will continue into mid-next week, maintaining typical summer surf. A Small Craft Advisory is in effect for some areas, and updates are available on the National Weather Service website. Conditions are expected to be unsettled but manageable for surfers and mariners.
