The surf will remain below advisory levels on all shores through the forecast period. The current small south and south-southwest swell is fading and will drop into the weekend only offering surf around waist-high or smaller levels, although select areas may see slightly better size. Another small southwest swell is possible around mid-week, but this energy is coming out of the Tasman Sea and will be heavily shadowed when it reaches Hawai`i’s shores. Short period waist-high windswell along east facing shores will continue into next week, with the largest surf expected during the weekend. Trades will increase further on Saturday, and the small craft advisory may be expanded to additional marine zones over the weekend. A slow decrease in winds is expected next week. The surf will be rather small through most of the forecast period.

Weather Outlook for Saturday

Trade wind weather will continue through the forecast period as high pressure remains to our north. Clouds and showers will favor windward and mauka areas. Expect wind speeds to stay locally breezy in traditionally windy areas through the weekend, before dropping next week to moderate levels.

A 1032 mb high far northeast of the main Hawaiian Islands is driving moderate to locally breezy trade winds across local waters this evening. A ridge extends southwest from the center of this high to a position about 450 miles northwest of Kauai. A front about 550 miles northwest of Kauai will continue to weaken, allowing the ridge to build westward and strengthen. This will steepen the pressure gradient across the islands, allowing locally breezy trade winds to continue through the weekend.

Clouds and showers will favor windward slopes through the forecast period, with fluctuating shower coverage and intensity expected as pockets of moisture ride the trades into the islands. A few showers will reach leeward areas of the smaller islands as stronger winds push moisture over the mountains faster than the mountains can wring it all out. For the lower leeward slopes of the Big Island, a diurnal pattern of clearing skies at night and early mornings will give way to cloudy skies and isolated showers in the afternoons.

Models show an upper trough will advect colder air aloft by the middle of next week. This will increase instability and could lead to an uptick in shower activity Tuesday night through Wednesday night.
