Area Forecast Discussion National Weather Service Honolulu HI 921 AM HST Mon Jul 6 2020

SYNOPSIS. Trade winds will gradually increase today, and become locally breezy on Tuesday, lasting into the weekend. More typical trade wind showers will return today, focused over the windward slopes, and producing afternoon showers over leeward portions of the Big Island.

DISCUSSION. High pressure building north of the state will bring a gradual increase of trade winds during the next 48 hours. The current light to moderate trade winds are expected to become breezy by Tuesday afternoon then persist through the rest of the week.

As far as precipitation, the trade winds will focus passing showers over windward and mauka areas with a few isolated showers making its way over to leeward areas from time to time. A slight uptick of moisture will bring subtle increases in trade wind showers on Wednesday and Thursday. Typical breezy trade wind weather is expected for next weekend.

AVIATION. High pressure far to the north of the state will keep light to locally moderate trade wind flow in place through twenty-four hours. Ragged clouds and isolated showers will continue to impact mainly north and east facing slopes and coasts. Shower activity is expected to increase after midnight due to nocturnal cloud top cooling.

AIRMET Sierra for mountain obscuration across Windward Kauai has been canceled, but mountain obscuration may become an issue again for windward slopes late tonight or Tuesday morning. For this afternoon and evening, VFR conditions are expected to prevail all areas with the exception of brief MVFR CIG or VIS in showers.


MARINE. Trade winds will increase today into the moderate to fresh range. Winds are expected to ramp up to fresh to strong tonight and Tuesday, likely requiring a Small Craft Advisory for the windier waters around Maui County and the Big Island. The advisory may need to be expanded to additional marine areas as the trades continue to increase though the week.

Surf along south facing shores will remain small through the week, with mainly a mix of small south and south-southeast energy. A slightly larger south swell arriving late Wednesday may bump up surf heights Thursday. Surf along east facing shores will rise slowly this week as the trades increase locally and upstream of the islands. Surf along north facing shores will remain small through the upcoming week.

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.
