Breezy trade winds will be diminishing a little Sunday but should remain over the islands through Wednesday, with isolated to scattered showers for windward and mauka areas, mainly during the night and early morning hours. Rainfall totals should remain light. Winds could become light and variable for the second half of the coming week.
In surf, the current northwest swell has dropped below advisory levels for now. A new swell is expected to fill in Sunday, peaking Sunday night into Monday near warning levels. An even larger swell could generate warning level surf for north and west shores midweek. East shores will remain elevated and choppy near advisory levels through the weekend, and then gradually lower as the trade winds ease.
For mariners, a small craft advisory is up for most Hawaiian coastal waters through at least Monday afternoon, but could be extended due to high seas from the expected ocean swells.
