Area Forecast Discussion National Weather Service Honolulu HI 330 PM HST Fri May 29 2020

SYNOPSIS. Breezy trade winds with limited windward showers are expected through the weekend. Increasing shower coverage is possible early next week as enhanced moisture rides in with the trades.

DISCUSSION. A high pressure ridge to the north will maintain breezy trade winds into next week. Through the weekend, limited showers will focus over windward and mountain areas as the trades push moisture into the windward mountain slopes. Some brief showers will reach leeward locations as well with the best chances overnight and into the early morning hours. Models are anticipating an old frontal boundary to bring increased trade winds showers Tuesday into Wednesday as the boundary works through the island terrain.

AVIATION. A rather benign trade weather pattern will persist into Saturday, with moderate ENE trade winds delivering stable (and a few showery) low clouds that will primarily affect windward areas. Additionally, expect evening clouds to drop a few showers over leeward slopes of the Big Island, with gradual overnight clearing. While these showers may result in brief MVFR VIS/CIG, no AIRMETs are expected as VFR conditions will prevail.

MARINE. High pressure ridging north of the islands will maintain moderate to locally breezy trade winds over Hawaiian coastal waters. However, winds this afternoon have eased sufficiently to be able to cancel the Small Craft Advisory (SCA) that had been posted over the windier areas around Maui County and the Big Island. If trades become a bit stronger over the next day or two, an SCA may again be warranted for those typically windy zones.

A series of swells from the southern hemisphere will maintain moderate surf along south facing shores through the weekend. A large south swell building early next week could produce surf above the High Surf Advisory (HSA) level by Wednesday.

Surf will remain well below HSA levels along other shores. A small north swell will build Saturday, then fade out Sunday. A small northwest swell is expected through the middle of next week. Surf along east facing shores will remain small.

HFO WATCHES/WARNINGS/ADVISORIES. None.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
