Area Forecast Discussion National Weather Service Honolulu HI 348 AM HST Sun May 31 2020

SYNOPSIS. Expect trade wind weather through the entire forecast period as high pressure remains north of the area. Clouds and showers will favor windward and mauka areas, with generally dry weather expected over most leeward locations. An old frontal boundary interacting with island terrain may produce increased showers Tuesday and Wednesday.

DISCUSSION. A surface high northwest of the main Hawaiian Islands is driving moderate trade winds across local waters this morning. This high will gradually move eastward to a position northeast of the area by Wednesday. This will slightly decrease trade wind speeds. High pressure will then rebuild due north of the area Thursday through Saturday, prompting a trade wind speed increase.

Our airmass is rather dry and stable, with an upper ridge centered several hundred miles to our north. Pockets of moisture embedded within trade flow will fuel light passing showers over windward and mauka areas, with most leeward locations remaining generally dry. Moisture associated with the remnants of an old front is forecast to move through the area Tuesday and Wednesday, likely increasing shower coverage across windward and mauka areas.

AVIATION. A surface high located some 450 nm NW of Kauai will be moving NE at 20 kt during the next 24 hours. In doing so, a moderate to locally strong NE trade wind flow will be blowing through the islands today and the early part of this evening before becoming lighter. AIRMET Tango is in effect for the lee side of the mountain ranges of all islands through 22z and is likely to be extended.

Upwind cloudiness has lessened in the past couple of hours, resulting in minimal showers. If this trend continues, it will be a mostly dry morning, area-wide, and likely last through most of today.

MARINE. A high to the north of the area will maintain moderate to locally breezy trade winds through the weekend. Along these same lines, trades have strengthened a bit overnight, so a Small Craft Advisory has been posted for the Alenuihaha Channel through tonight. The trades will weaken Monday as the high moves northeast, but will rebuild Wednesday into Thursday as the high strengthens.

South shore surf will be somewhat elevated this weekend, with a larger south swell expected to gradually build from Monday into Wednesday, then gradually diminish into Friday. Peak surf heights could be large enough to warrant a High Surf Advisory (HSA) for south facing shores of all islands, potentially as early as Tuesday, but more likely Wednesday. Surf will remain well below HSA levels along other shores through the period, although a couple of small swells from the north and northwest will keep surf from going flat along north facing shores. The latest Surf Discussion (SRDHFO) contains details on the swell sources.

HFO WATCHES/WARNINGS/ADVISORIES. Small Craft Advisory until 6 AM HST Monday for Alenuihaha Channel.

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.
