For those seeking a beach retreat or a hiking adventure in Hawaii, it's important to consider what Mother Nature has in the docket. Moderate trade winds will caress the islands for the majority of the weekend, potentially intensifying as the new week dawns. Vacationers should expect a typical pattern of passing showers, especially in windward and mountain areas, mostly during late night to early mornings. However, an upper level disturbance slowly drifting from east to west over the islands might just ramp up the shower meter this weekend, according to the National Weather Service Honolulu Forecast Office.
As this week rolls into the next, a high pressure ridge steadfast north of Hawaii continues to play conductor to the breezes we're feeling across the archipelago. Isolated thunderstorms could dot the Big Island come Friday and Saturday afternoons, with Kauai getting its share during the weekend. Early next week, after the upper low weakens and moves away, the ridge north of the island will tighten its grip, boosting those moderate trade winds to a breezier tune. Consequently, the heights of the trade wind thermal inversion will lower, facilitating more stable conditions and limiting shower activities.
Pilots soaring through Hawaiian skies should anticipate moderate trades through the coming days. The NWS also flags a potential for mountain obscurations across windward locales in the early hours as these cloud bands and showers shift. Travelers shouldn't be alarmed if they experience temporary bouts of poor visibility. The forecast for the weekend suggests essential VFR (Visual Flight Rules) conditions will likely prevail, with intermittent moments where an AIRMET Sierra might be issued due to increased chances of showers as an upper-level low approaches the islands.
To those with their sails unfurled and keels dipped, the marine forecast holds a steady stream of moderate to fresh trade winds through to the weekend's end. The Hawaii forecasting office suggests that these trades could amplify to fresh and strong levels by next week, which may trigger a Small Craft Advisory for the more blustery channels near Maui and the Big Island. Surf conditions along south shores will hang around the average mark until Saturday, then dip below usual levels into much of next week. North shore waters appear poised to retain their seasonal flatness, while east shores should see a swell increment bending back to typical patterns as the trade winds gather strength.
