Honolulu's weather forecast is taking a turn this week as a strong high pressure system north of the islands ramps up trade winds through Thursday. According to the National Weather Service (NWS), this will result in breezy to windy conditions, particularly over terrain favored windy areas of Maui and the Big Island. The trade winds are not here to stay at those levels, however, with predictions showing a gradual shift to more moderate speeds starting Friday as we head into the weekend.
The NWS discussion also highlights an upper-level disturbance moving in which could potentially enhance shower activity from Saturday into early next week. The old frontal boundary that's been hanging around is expected to continue its journey south of the islands, leaving enhanced shower activity over east Maui and parts of the Big Island through the morning. Yet, as the weekend approaches, islanders might need to keep their umbrellas at the ready, due to the approaching low pressure system from the northwest.
Boaters should also be aware of the weather conditions. The forecast includes a Gale Warning in effect from Tuesday morning through early Wednesday morning for Maalaea Bay, Pailolo Channel, and Alenuihaha Channel. Meanwhile, a Small Craft Advisory remains in place for the remaining Hawaiian waters, cautioning mariners of the strong trade winds which are anticipated to ease off later in the week. This variable weather serves as a reminder for those on the water to stay tuned to updates and take appropriate precautions.
Beyond the marine implications, surfers can expect rough conditions along east facing shores. The NWS notes that the strong trade winds will keep the surf high, potentially reaching High Surf Advisory criteria midweek. In contrast, south facing shores will see smaller waves.
Lastly, Wind Advisories are on the calendar for multiple areas including Lanai Mauka, Kahoolawe, Maui Windward West, and Big Island North, among others, from Tuesday morning to Wednesday. These advisories, along with the marine warnings, indicate the need for caution in windy conditions. With the weather situation changing, it is important to stay informed through the latest forecasts from NWS for safety and planning.
