A northwest swell associated with a developing storm-force low far northwest of the islands is forecast to fill in across local waters late Sunday, peak Monday, then slowly ease into midweek. Guidance supports a peak around 7 to 8 feet at the northwest offshore buoys late Sunday night into Monday morning. However, if this swell comes in higher, surf could near advisory levels for Monday along north facing shores, especially along north and west facing shores of Kauai where the swell is forecast to be slightly larger anyway.

Surf along south facing shores will remain small through this weekend with mainly short-period south and southeast swell energy expected. A large area of gale- to storm-force west-southwest winds around 1300 nm south-southeast of New Zealand will send some small southerly energy our way. As this system continues eastward across the south-central Pacific, the area of gale- to storm- force winds is forecast push northward and become oriented more in our direction. This may provide a slight enhancement out of the southeast locally by next weekend.

Small and choppy surf will ease along east facing shores as the winds shift out of the south and become light over the weekend. Rough surf along east facing shores may return with stronger trades by Thursday.

Weather Outlook for Saturday

Winds shifting out of the southeast through early Saturday will turn more south over most of the island chain on Sunday as a front approaches the state from the northwest. Humid and hazy weather with daytime sea breezes and nighttime land breezes will develop over most areas, while clouds and showers will favor interior portions of the islands during the afternoon and evening hours. Unsettled weather may affect Kauai and vicinity as well as Oahu Monday. Trade winds will build back in around Wednesday and may become rather strong toward later part of next week.

Low level winds are in the process of switching to the southeast this evening, as revealed by latest radar wind profile data. A surface high pressure ridge north of the islands is slowly sagging south toward the state. This is in response to an advancing front, further northwest of the ridge. As the low level wind flow turning more southeast, much of low clouds embedded in the synoptic wind flow will stay offshore of the western islands. But then , plume clouds developed on the lee side of the islands may affect the downstream islands to the west, especially for Kauai and Niihau through rest of the evening into early Saturday. Windward east to southeast Maui and Big Island will be exposed to the southeast winds, therefore embedded low clouds will reach those areas at times, bringing some showers. Winds will become light over the islands under the increasing southeasterly synoptic winds, allowing land breezes to develop and becoming more widespread. This may also lead to some clearing of the skies over the islands overnight.

By Saturday, humid and hazy conditions are expected to slowly set over much of the islands as synoptic southeasterly winds prevail. The weak background wind flow will allow daytime sea breezes to be widespread over the islands, with clouds and showers developing over the interior sections of the islands during afternoon and evening. Some clearing may occur over the islands at night under the land breezes. Atmospheric conditions should remain stable enough to hinder heavy shower development on Saturday. Winds will veer more southerly on Sunday as the cold front approaches Kauai. Similar weather conditions will persist over the islands. Furthermore, moist tropical airmass will be drawn to much of the state under the more southerly wind flow on Sunday, with airmass becoming more unstable over the western end of the main Hawaiian islands, increasing the chance of showers over the islands, especially in the afternoon and early evening.

Latest model solutions have better agreement upon how this pending weather scenario will evolve, and it looks like the front will stall just northwest of Kauai on Monday. But then, moisture ahead of as well as associated with the front will reach Kauai Monday. Meanwhile, the upper level dynamics associated with front will also be close enough to Kauai to provide some atmospheric instability for Kauai and vicinity. Therefore, unsettled weather is forecast to affect the western islands on Monday, with locally heavy rain and a slight chance of thunderstorms possible for Kauai and vicinity, and a chance for heavy showers for the interior sections of Oahu Monday afternoon. The rest of the state may be far enough away to the east to experience less weather.

Model solutions are still in good agreement about the front retrograding to the west beginning around Tuesday as a strong surface high from far northwest advances east. Easterly trade winds are expected to return to the islands by Wednesday and could become locally strong by later part of next week as the strong high is forecast to stay far north of the area.
