HONOLULU, Hawaii (HawaiiNewsNow) - Trade winds will hold firm through the next seven days. The remnants of former tropical cyclone Barbara will drift westward overnight with continued wet weather lasting into Tuesday. More stable drier trends are expected from Wednesday through Friday with wet trade wind weather returning to the southeastern islands over the upcoming weekend. On Saturday and Sunday, another tropical disturbance develops far south of the Big Island. Long range model solutions continue to track this system northwestward into the Hawaii region on Sunday. Deep tropical moisture will affect mainly the Big Island and portions of Maui counties with another round of wet trade wind. The moisture is expected to hang around for the first few days of next week.
The combination of a declining south-southwest swell and a small southeast swell generated by strong southeast trade winds in the South Pacific last week will likely maintain surf heights near or slightly above the summer-time average along exposed south facing shores through mid-week. New long period south-southwest swells arriving starting Friday are expected to cause surf to reach the HSA criteria along south facing shores next weekend. This elevated surf may require the HSA to continue into early next week.
