Area Forecast Discussion National Weather Service Honolulu HI 947 AM HST Sun Jan 26 2020

SYNOPSIS. Moderate trade winds will continue through early Monday, with scant showers favoring windward areas. Winds will shift to southeasterlies Monday through Thursday as a series of fronts approach from the northwest, with land and sea breezes developing across the smaller islands. Rather dry conditions will prevail through much of the work week. A strong front will move into the islands Friday into next weekend, potentially bringing wet and unsettled weather.

DISCUSSION. High pressure far east northeast of the state is driving moderate trade winds across local waters this morning. Satellite loop shows mostly clear skies, with patches of low clouds across windward slopes. Radar shows isolated showers moving across windward waters east of Oahu and Kauai, with very little activity noted elsewhere.

The subtropical ridge will remain north of the islands through Tuesday before sliding southward across the state Wednesday and Thursday. A front will approach from the northwest through the first half of the work week, with a second and stronger front expected to move into the western islands Friday before stalling next weekend. Moderate trade winds will prevail through Monday morning, then shift to southeasterlies Monday afternoon through much of the work week. Most of the smaller islands will see light and variable winds, with development of land and sea breezes expected. Strong trade winds could return late Friday into next weekend as high pressure builds in behind the second front.

Rather dry weather will prevail across the islands through late in the work week. Scant showers will favor windward areas today through Monday morning. By Monday afternoon, sea breeze development will likely increase cloud cover across mauka areas. Clearing will occur each night. This pattern of scant windward showers combined with increased afternoon cloud cover will hold through Thursday. More unsettled weather may occur beginning Thursday night or Friday and last into next weekend as the second front affects the islands.

AVIATION. A ridge north of the islands will provide light/moderate trade winds through tonight. Expect isolated to scattered showers along windward coasts and slopes with ISOL MVFR.

MARINE. A ridge of high pressure north of the area will maintain moderate to locally strong trade winds across most coastal waters through Monday. Beyond that time frame, a couple of fronts approaching the area from the northwest through the week will weaken the winds and turn them toward the east and southeast.

The current northwest swell continues to remain elevated, and a High Surf Warning remains in effect for exposed north and west facing shores of the smaller islands through this afternoon and a High Surf Advisory for west facing shores of the Big Island through tonight. We will continue to monitor the buoys, and update the warning and advisory as warranted.

A Small Craft Advisory is in effect for all Hawaiian waters except Maalaea Bay through today due to a combination of winds and large seas from the northwest swell. Some marine zones will likely hold on to SCA level seas into Monday.

Surf will remain elevated along north and west facing shores as a progressive weather pattern across the northern Pacific keeps a series of large northwest swells moving through the islands, at least through the middle to latter part of next week. The next northwest swell is expected to arrive Tuesday night from a large fetch of gales currently blowing in the northwest Pacific. Latest model guidance is suggesting the swell to peak at high end advisory levels sometime Wednesday.

Surf along exposed east facing shores will remain rather small through the period due to the lack of persistent trades locally and upstream across the eastern Pacific.

Surf along south facing shores will remain small through next week. A couple background south swells expected over the weekend, and again Tuesday, should be enough to keep things from going flat.

HFO WATCHES/WARNINGS/ADVISORIES. High Surf Warning until 6 PM HST this evening for Niihau-Kauai Windward-Kauai Leeward-Waianae Coast-Oahu North Shore-Oahu Koolau-Molokai-Maui Windward West-Maui Central Valley-Windward Haleakala.

High Surf Advisory until 6 AM HST Monday for Kona-Kohala.

Small Craft Advisory until 6 PM HST this evening for all Hawaiian waters except Maalaea Bay-

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
