The current north-northwest swell is on the decline and both the High Surf Advisory and Small Craft Advisory for seas has been cancelled. Swell and surf from this event will continue a slow decline through the weekend. As the north-northwest swell continues to subside this weekend, a small north swell is expected to arrive Saturday. In addition, the first of a series of small west-northwest swells will arrive Sunday night and continue through first half of next week. Elsewhere, small south swells will bring a bump to surf heights along south facing shores into next week. Strengthening trade winds will cause a slight increase in short-period choppy surf into next week.

Weather Outlook for Saturday

A return to a drier trade wind pattern will be taking place today as the remnants of a front gradually lifts north of Oahu this morning and Kauai by this evening. A ridge of high pressure will maintain a mostly moderate trade wind flow across the main Hawaiian Islands through the first half of the new work week. Showers riding in with the trades will favor the windward and mountain areas of all the islands, especially during the nights and mornings.

Showers have become less across Oahu since midnight as the remnants of a frontal band edges north of Oahu. The remnants are now focused on Kauai. A slow but improving trend is instore for the Garden Isle for the rest of today. A more normal trade wind pattern should be in place by this evening for all of the main Hawaiian Islands, and this pattern is expected to last through the first half of the new work week.

The trades are being furnished by a 1025 mb surface high pressure system, currently located 650 miles N of Oahu. This high will be moving off to the east and stall some 1200 miles NE of Oahu by Sunday night. The associated ridge that reaches westward will remain some 450 miles N of Kauai through Wednesday of next week thus keeping the islands in a trade wind flow. There are no satellite derived winds this morning since the pass missed the islands, but elevated sea returns from the Naalehu NEXRAD suggested some locally strong trades blowing off the Kau coast. Wind data from around Maui also pointed to the likelihood of strong trades in the Maalaea Bay and the Alenuihaha Channel. We believe this period of locally strong trades will be brief and only for today. This is due to an upper level trough moving into range where it will help soften the trades a notch or two by this evening. This upper trough is currently 700 miles W of Kauai, and should be 350 mile W of Kauai this evening.

Both ECMWF and GFS models are showing the trades with slight south component on Sunday, most apparent across the islands windward waters. Some weakness is noted with the trades over smaller islands as well that will bring on a sea breeze onshore flow along the leeward shoreline and interior areas of the smaller islands. Along with daytime heating, the result will be some afternoon cloudiness and a shower or two over these areas. This weakness is likely due to the upper trough sitting just W of Kauai. On Monday, the upper trough starts to fill which will allow the trades to strengthen to moderate speeds and to blow more from the east direction. The islands stays in this pattern through Wednesday.

The upper trough is also carrying a bit of high cirrus clouds over the islands. Models are suggesting that this cirrus can be dense at times to filter a good amount of the sunshine today. The cirrus should not be a factor for Sunday.
