Trade winds are expected to increase across the state as high pressure builds in from the northeast. Thus a Small Craft Advisory, beginning Friday morning, has been posted for the typically windier zones around Maui County and the Big Island. The SCA will be in effect through the day Saturday, but will likely need to be extended breezy conditions should continue through the weekend.

A small long-period west-northwest swell is expected to fill in late tonight and hold into the weekend before fading into next week. Surf is expected to remain below average through early next week.

Surf along east facing shores will begin to rise Friday through the weekend as the trades strengthen locally and upstream of the islands. A northeast swell (11-13 sec), from a band of strong winds that is forecast to set up across the eastern Pacific this weekend, is expected to fill in and impact the beaches early next week. The northeast swell, combined with the trade wind swell, could cause surf to approach advisory levels Monday through Tuesday.

Surf along south facing shores will remain small through the weekend, but WAVEWATCH III depicts a long-period south (170-180 deg) swell filling in locally around midweek.

Weather Outlook for Friday, 3rd November 2017

Summary

Trade winds will gradually strengthen tonight and Friday, becoming locally breezy this weekend. The returning trade winds will bring an increase in windward showers Friday night and Saturday before a drier and cooler air mass moves in from the northeast on Sunday. Moderate trade winds are expected to deliver passing windward showers for most of next week.

Detailed Discussion

A trend toward a more typical trade wind weather pattern is expected over the next 12 to 24 hours, with a slight uptick in windward showers expected Friday night and Saturday, and breezy conditions through the weekend. The returning trade winds will bring relief from the vog and humidity, especially when a cooler and drier air mass moves in from the NE on Sunday.

Latest surface analysis still features a small surface high, about 600 miles NE of the islands, with an associated ridge just N of Kauai. Trade winds S of the ridge are strongest near and S of the Big Island and weakest over Kauai. Satellite and radar images indicate a dry pattern statewide, and little change is expected through Friday.

A stabilizing mid-level ridge over the E end of the state will shift NW and remain very close to the islands well into next week. Despite this, the trade wind flow may become somewhat showery Friday night and Saturday as shallow moisture pooled to the N and NE of the islands becomes embedded within the trade flow. A large and strong high in the Gulf of Alaska will build S the next couple of days. As it builds to the NE of the islands late this weekend, it will support gusty trade winds while also sending a cooler and drier air mass toward the area, with dew points dipping into the mid 60s and PWAT dropping to near 1 inch.

This air mass will modify relatively quickly early next week, with moderate trade winds delivering passing windward showers in a continued stable atmosphere.
