The current northwest swell will continue to lower through the weekend. Select north shore breaks may still see sets coming in at overhead levels, but most areas will only pull in waist- to chest-high surf. Small to moderate south-southwest swell may be found along select south shores with wave heights around waist- to chest-high levels. Small short-period surf may be found along windward coasts as well. Another small northwest swell is due in on Tuesday and Wednesday. Surf heights will remain well below advisory levels. Storms in the far southern hemisphere will continue to produce small background surf along south facing shores throughout the forecast period, and the easterly trades will continue to produce short period choppy surf along east facing shores.

Weather Outlook for Saturday
A trade wind pattern will hold through the weekend and into the new work week as high pressure remains to the north of the islands. Showers and clouds riding in with the trades will favor the windward and mountain areas. A few of these showers will drift into the leeward areas of the smaller islands. Lee areas will continue dry. Showers will be more frequent during the nights and mornings.
Moderate to locally strong trade winds will continue into the new week as a series of high pressure systems passes north of the islands. The strength of the trades will ease off briefly and very slightly on Sunday, mainly felt on the west end of the island chain, but breezy condition will be back by Monday night or Tuesday area wide. This slight drop in the trades is due to a front pressing on a surface ridge. This ridge will get as close as 400 miles north of Kauai Sunday before retreating to the north. The front dissipates high pressure takes over resulting in breezy trades once more.
Satellite imagery this morning shows quite a bit of low clouds moving through the island chain especially between Oahu and the Big Island. The islands are in an extensive area of shower bearing clouds that stretches upwind of the Big Island and Maui for at least 300 miles. Perhaps a mid level disturbance is helping accentuate these trade showers as well. On the other hand, Kauai is the driest this morning with only a few spotty showers. The GFS solution shows a slightly drier and more stable air mass easing in on Sunday and lasting through Tuesday night. The mid level disturbance may also promote a few more showers for the Kona slopes this afternoon.
Also, under this trade wind pattern, the frequency of the showers will be more during the nights and mornings, becoming isolated by mid morning or noon for especially the smaller islands.
