The National Weather Service has issued a High Surf Warning for north facing shores of Maui, effective through 6:00 pm Saturday evening at which time it will be downgraded to a High Surf Advisory. The better exposed north shore breaks should still see surf in the double- to triple-overhead range while lesser exposed breaks come in closer to head-high to double-overhead levels. A new northwest swell is expected to arrive Saturday which will keep this action going through Sunday before dropping through the beginning of the upcoming work-week. Although we may see minor surf through next week, nothing significant is expected. Small south-southwesterly swells may continue over the weekend and there is potential for more minor south swells through the rest of the forecast period.

Hazardous ocean conditions will persist over the weekend due to a combination of moderate to strong northeast to east winds south of high pressure passing to the north and northwest of the islands. As a result, the small craft advisory will remain in place through the weekend. Winds and seas will trend down through the upcoming week beginning Monday as the north and northwest swells ease and a cold front approaches and moves into the region bringing increasing rain chances.

As mentioned above, the current northerly swell in place will likely hold through the day today then steadily ease Sunday into the upcoming week. A combination of this northerly swell holding through this evening and a new long-period northwest swell (320 deg) filling in will continue to support warning-level surf along north facing shores through today. This new northwest source will also support advisory-level surf along exposed west facing shores by this afternoon on most islands, which should hold through Sunday.

Weather Outlook for Saturday

High pressure north of the state will maintain locally breezy trade winds through the weekend. The trades will focus clouds and showers mainly over windward areas. Winds will weaken and shift out of the south starting Monday as a front approaches from the northwest. Deep moisture over the state and a trough aloft may keep the weather unsettled over the islands through the middle and later part of next week.

Radar and rain gauge data show scattered mainly light showers over windward parts of the state, with dry conditions elsewhere. Surface analysis depicts a 1025 mb high centered about 750 miles NW of Kauai, with fresh trade winds prevailing over the islands. The state lies under dry NW flow aloft, between a trough along 145°W and a ridge near 170°W. Mimic-tpw satellite imagery shows a dry airmass surrounding the state, with estimated pwats ranging from 0.8 to 1.1 inches. The 12Z soundings bear this out, with the inversion near 5500 feet and pwat of 0.87 inches at Lihue, and the inversion near 8500 feet and pwat of 1.16 inches at Hilo.

Little change is expected for today through Sunday. High pressure will shift slowly eastward to the north of the state, maintaining moderate to fresh trade winds over the islands. Available moisture will be shallow with pwats remaining generally below normal, so expect mainly light showers to continue focusing over windward areas, and mostly clear/dry conditions for leeward areas.

There continues to be the potential for a major change in the weather pattern across Hawaii for next week. Latest models continue to bring a substantial mid level trough and surface front across the north central Pacific, crossing the international dateline on Sunday and slowly approaching the state from the west through Tuesday. Monday appears to be a transition day, with winds swinging around to the southeast well ahead of the front. Models continue to show some timing differences in bringing the deeper moisture eastward into the state, but it appears that there could be some potential for heavier showers at least on Kauai Monday afternoon. More active weather could spread eastward across all of the state Monday night or Tuesday, as a shortwave trough approaches from the west and deep moisture spreads overhead. It remains unclear if the actual surface front will reach the state, but regardless it appears that unsettled weather will remain possible through the end of the work week. A series of shortwaves will maintain a mid/upper level trough just to our west, with ample deep moisture remaining in place to the east of the trough. It is still too early to be confident in the details, but the potential exists for locally heavy rains and isolated thunderstorms, along with wintry conditions at times on the Big Island summits. Many areas currently affected by the wintertime drought could receive beneficial rainfall.
