A surface high north of the area will move northeast through Saturday. The high is producing locally strong trade winds over Hawaiian waters. A Small Craft Advisory continues for strong trade winds in the windier areas near Maui County and the Big Island. A new high building northwest of the area will cause the trade winds to strengthen further this weekend. The SCA will likely be expanded starting Saturday.

Surf is expected to remain below High Surf Advisory (HSA) thresholds along all shores through this weekend. Surf along east facing shores will remain rough through Sunday night due to the trade winds, but heights will remain moderate. There will be some increase in surf heights along east facing shores next week as trade winds strengthen.

A small northwest swell will build Saturday evening, peaking Sunday. A slightly larger swell is expected to arrive Sunday evening and peak Monday. Another moderate swell is possible next Thursday.

Surf along south facing shores will remain small through early next week. Lows in the southern hemisphere may strengthen and shift east enough to produce some bigger surf along south facing shores by the end of next week.

Weather Outlook for Saturday, 21st April 2018

Summary

Breezy trade wind weather is expected over the weekend with clouds and showers focused over windward areas. Some of these showers will blow over to leeward locations on the smaller islands, while the Kona side of the Big Island will see afternoon clouds and showers. Trades will strengthen to locally windy levels next week.

Detailed Discussion

High pressure far northeast of the main Hawaiian islands is driving locally strong trade winds across the state this evening. Radar shows scant shower activity upwind of the islands, but satellite loop shows layered clouds lingering across Maui county and the Big Island. Afternoon soundings showed PW in the 1.1 to 1.5 inch range with increasing stability.

Models show the high pressure to the north will keep trade winds on the breezy side through the forecast period, gradually gaining strength and spreading westward over the weekend and into next week. Clouds and showers brought in by the trades will favor windward and mauka areas, but leeward areas may get wet from time to time as well as winds increase. The layered mid and upper level clouds will continue moving eastward, clearing Maui County tonight and the Big Island Saturday morning. Drier and clearer weather is then expected through the rest of the forecast period.
