Honolulu prepares for a season of gentle breezes and mild showers, as foreseeable weather patterns hold steady. The state is expected to experience "breezy and generally dry statewide conditions the next several days," with scattered showers primarily hitting the windward areas and higher terrains. A high-pressure system settled roughly 1,800 miles northeast of Hilo is set to maintain the familiar easterly trade winds well through the weekend, according to the National Weather Service latest forecast.
As dew points drop from the low 70s to the mid-60s, the Hawaiian archipelago is slowly but surely drying out. Rainfall has decreased since Sunday, with the heaviest downpours registering between half an inch and an inch and a half, according to the National Weather Service reports. The forecast also indicates, that a surface trough echoing a waning upper trough will retract westward, further diminishing moisture levels. This changing dynamic, coupled with the mid-level dry air propelling westward, signifies mostly dry days ahead with the exception of some showers over the Big Island's Kona slopes.
Light showers are slated to continue favoring windward and mauka regions through mid-week. A minor shift might occur with slight easement in trades by the week's end due to weak upper-level troughing and the establishment of a broad surface trough west of the state. "Subtle changes will occur later this week as trades slightly ease," the National Weather Service report suggests, forecasting only a moderate increase in moisture to cause a small uptick in trade wind showers, mainly on mauka slopes come Friday.
For aviators, the National Weather Service foresees predominately Visual Flight Rules conditions, although some mountain showers might cause minor visibility and ceiling issues. Marine forecasts have seen a downscaling in advisories, with the Small Craft Advisory now limited to the gustier channels around Maui, and the Big Island until Wednesday evening. Surfers should keep an eye out for a moderate long-period swell hitting south shores by Saturday, potentially escalating to High Surf Advisory levels. Conversely, north shore swells are set to taper off while, east-facing shores will experience some choppiness due to enduring trades.
The current condition stands favorable for small craft operators in specified regions as stated by the National Weather Service, "Small Craft Advisory until 8 PM HST Wednesday for Maalaea Bay, Pailolo Channel, Alenuihaha Channel, Big Island Leeward Waters, Big Island Southeast Waters." This advisory implies that craft operators should exercise caution due to moderate to potentially strong trade winds that may become gentler as the week concludes.
