North-northeast swells produced by gales associated with a low pressure system far northeast of the islands will continue to provide surf through early next week. Surf from these swells will remain below the high surf advisory threshold along north and west facing shores, but will remain above the advisory threshold along east facing shores through Saturday evening. There is little to no swell to be found along south facing shores. Additional lows in the northwest Pacific may become more active by the middle of the week and there is the chance of advisory-level surf along north and west-facing shores by the end of the week. A surface ridge shifting southeast over the area will keep winds below the 25 kt Small Craft Advisory threshold through next week. Seas will remain below the 10 ft SCA threshold through most of that time, but northwest swells building during the second half of next week could produce seas approaching 10 ft.

Weather Outlook for Saturday

A north to south surface ridge west of Kauai will become aligned east to west early next week. The ridge will then move south slowly and remain near the islands through the second half of next week.

Satellite and radar loops show clouds and light showers over the east side of the Big Island of Hawaii with isolated clouds and dry conditions elsewhere. Mostly dry weather will continue today. A trough aloft east of the area will maintain strong west winds over the summits of Mauna Kea and Mauna Loa. Winds should subside below the advisory threshold tonight.

A north to south surface ridge is about 500 miles west of Kauai with a northeast to southwest surface trough about 850 miles east of the Big Island. The pressure gradient between these two systems is producing gentle to moderate north winds over the islands. The ridge will gradually tilt, becoming northeast to southwest over the weekend. As the ridge shifts, the winds over the islands will become northeast trades tomorrow and easterly trades on Sunday. The trades will push a few showers over windward areas, but rainfall will be light over windward areas and leeward areas will remain mostly dry.

Early next week a front will approach from the northwest and stall well northwest of Kauai. The surface ridge will shift south over the islands and winds will become light and variable. Sea breezes will produce clouds and showers in the afternoons while land breezes will bring clearing skies during the nights and early mornings.

A stronger front will approach from the northwest around the middle of next week. This front is also expected to stall northwest of Kauai, but may get close enough to produce moderate southwest winds and scattered showers around Kauai and Oahu. There are differences among the global models with the timing and strength of the front.

Central Valley (Kahului, Spreckelsville):

Clear. Lows 59 to 64. Northeast winds 10 to 15 mph.
