Trade winds will be blowing at moderate to locally breezy speeds for the King Kamehameha Day holiday, with just a few showers riding in for windward and mauka areas. The trades will slow down just a little as we head into Wednesday, with some minor variations in the intensity of the trade showers. The trades will become rather light as we head toward the end of the week and may shift a little south of east, which could spread volcanic emissions on the Big Island toward the Hilo District. Too soon to have high confidence in that forecast that far out, but we'll monitor it closely.
Surf has fallen below advisory levels for south shores. The next long-period swell is expected sometime on Friday. The somewhat breezy trade winds will continue to push a choppy swell to east shores until the middle of the week. A Small Craft Advisory remains in effect for the usual windier waters around Maui County and the Big Island through Monday afternoon.
