A surface high centered far north-northeast of the state will move south through Monday, producing locally strong trade winds over the coastal waters. A Small Craft Advisory remains posted for the typically windy waters adjacent to the Big Island and the islands of Maui County through Monday afternoon. In addition, the winds are forecast to strengthen to the SCA criteria over the Kaiwi Channel and the remainder of the waters around Maui County today. Trade winds will decrease by late Monday as the surface high weakens northeast of the islands, and a front moves to a position far north-northwest of the region. Winds and seas are forecast to remain below the SCA criteria from Monday night through Thursday.

The current moderate northwest swell is expected to continue through this morning, before gradually declining from later today through Monday. Surf is expected to remain below the High Surf Advisory criteria along exposed north and west facing shores through mid-week.

Rough surf will increase along east facing shores into Monday due to the locally strong trade winds. In addition, a moderate northeast swell is expected to arrive later today or Monday, and hold into Tuesday. As a result of the combined trade wind and northeast swells, surf may approach the High Surf Advisory threshold along east facing shores late Monday and Tuesday. The northeast swell will slowly decline from Wednesday through early Thursday ahead of a new longer period north-northeast swell arriving late Thursday. The moderate north-northeast swell is forecast to continue from Friday into next weekend. This swell may cause surf to approach the High Surf Advisory criteria along some east facing shores on Friday.

Small background south swells will continue into early Tuesday. A new small south swell arriving late Tuesday is expected to peak Wednesday, before gradually declining Thursday. This should provide a slight bump in surf heights along most south facing shores across the state.

Weather Outlook for Sunday, 5th November 2017


Breezy trade winds will prevail today. Morning showers over windward areas will diminish by midday as a drier and slightly cooler airmass moves into the state from the northeast. A quiet weather pattern is expected through the upcoming week, with moderate trade winds delivering passing showers mainly to windward areas.

Detailed Discussion

Radar shows more quite a bit more shower activity than was observed 24 hours ago, especially across the windward waters and along some windward coasts. Rain gauges report scattered rainfall amounts mostly of a quarter inch or less during the past six hours over windward sections. Surface analysis depicts high pressure far NNE of the state, with fresh trade winds prevailing over the islands. Aloft, water vapor imagery shows ridging over and north of the state. The 12Z soundings show elevated inversions between 7000 and 9000 feet, with PW values around 1.4 inches. MIMIC-TPW satellite imagery shows a much drier airmass, with estimated PW values near or below one inch, located about 100 miles northeast of the islands and dropping quickly to the southwest.

Showery conditions will linger into the morning hours, especially over windward areas, but these should decrease quickly by midday, as the dry and slightly cooler airmass moves over the islands. Today will see breezy trade winds across many areas. Winds have also been sustained at 30-40 mph on the summits overnight. Similar winds are expected to continue at the summits through today, remaining below advisory levels.

The dry and relatively cool airmass will remain over the state tonight and Monday, with trade winds decreasing back to moderate levels, and little or no rainfall expected for most areas.

Quiet weather is expected to continue through the upcoming week. Models have come into better agreement in showing a brief respite from the trade winds on Tuesday over the western islands, as the background flow veers just enough to the ESE to allow afternoon seabreezes to develop there. With moisture and instability lacking, would expect just some afternoon cloud buildups and only widely scattered light showers at most over leeward/interior areas of Oahu and Kauai. Further to the east, trade wind conditions should continue over Maui and the Big Island. Trade winds are forecast to rebuild over the entire state by Wednesday, with persistent high pressure to our north then maintaining moderate trades for the rest of the week. Generally below normal PW values combined with ridging overhead should make for a rather dry week, with just the typical passing showers over windward and mauka areas.
