Honolulu residents can expect the moderate trade winds to persist throughout the week with scattered showers mainly hitting windward and mountain areas, particularly during the night and early morning. According to the latest update from the National Weather Service in Honolulu, a slight decrease in the usual wet conditions is anticipated today, although this will be followed by a gradual increase in moisture over the coming days.
The typical pattern of passing low-level clouds and showers over the north and east facing slopes will carry on, bringing scattered showers to these regions this morning. The National Weather Service forecasts a temporary return of drier conditions shortly after sunrise, lasting through tonight. However, as the ridge of high pressure to the north begins to weaken, trade wind speeds are expected to decrease slightly, maintaining moderate levels throughout the state for the rest of the week.
Flight operations should experience minimal disruptions due to moderate trade winds, which are expected to bring limited showers to windward and mauka areas. The National Weather Service predicts mostly Visual Flight Rules conditions, with brief periods of Marginal Visual Flight Rules visibility possible in heavier showers. Currently, there are no AIRMETs—weather advisories for aircraft—indicating stable conditions for aviation.
For mariners, the news is also stable with the cancellation of the Small Craft Advisory for the waters around Maui and the Big Island. Swell activity is expected to vary, especially on the north-facing shores, as a north-northwest swell diminishes today through Monday, followed by a fresh northwest swell arriving on Tuesday. Meanwhile, east shore waves should remain small for most of the week, although some areas might catch swells from the north. South-facing shores can expect small long-period southwest swells providing intermittent surf action in the coming days, with a noticeable increase around late Saturday into Sunday and Monday. In terms of weather advisories, the islands are in the clear with no warnings or advisories currently announced by the National Weather Service.
