Surf along east facing shores will steadily decrease through the weekend as trade winds relax. The next moderate northwest swell will fill in late Sunday and peak Monday before easing through midweek. A south swell will hold through the weekend producing moderate surf. A larger south swell is likely to arrive late in the week beginning as early as Thursday and holding through the Memorial Day weekend. In addition to potential advisory-level surf over Memorial Day weekend along south facing shores, minor coastal flooding will be possible due to the addition of higher than normal high tides.

Weather Outlook for Saturday

The islands will continue to see a light east southeast flow today, allowing for daytime sea breezes and overnight land breezes. Expect clouds and showers to form over the islands this afternoon with partial clearing tonight. Trade winds will start their return Sunday, with showers focused over windward and mauka locations. A wet trade wind pattern is likely throughout the upcoming week.

A 1028 mb high far northeast of the islands has a ridge extending to the southwest, and is about 200 miles north of Kauai, based on the latest surface analysis. The back ground flow is from the east southeast, with a weak pressure gradient over the islands, which has allowed for some localized land and sea breezes. Many areas have seen clearing overnight in the light wind regime. Expect clouds and showers to once again develop over the islands this afternoon.

Sunday should see the beginning of the return of trade winds as a high pressure system moves to the far northwest of the islands with a ridge due north. This system will begin to erode the southern end of a front that is currently about 550 miles northwest of Kauai. The high is expected to move to the east along 40N and strengthen during the first half of the week, which will bring strong trades back to the islands. Moisture from the front will be carried in on the trades, mostly impacting the windward and mauka areas. As the trades build, some of the showers will be carried to leeward areas.

During the second half of the week, the high will lift to the north and weaken, which should return trades to more moderate levels. During the same time, an upper level trough will dig near the islands. This combination will likely maintain a wetter than normal trade wind pattern over the islands.
