Area Forecast Discussion National Weather Service Honolulu HI 317 PM HST Sun Jul 5 2020

SYNOPSIS. Light to moderate easterly trade winds will produce showers over windward slopes tonight, while a few showers linger over leeward areas during the evening. Trade winds will gradually increase on Monday and become locally breezy Tuesday into next weekend. The stronger trades will promote a typical summertime weather pattern, focusing rainfall along windward slopes and producing afternoon showers over leeward Big Island.

DISCUSSION. Light to moderate trade winds have been overpowered by sea breezes across most leeward areas this afternoon. The islands lie between an area of moisture that moved through yesterday and a weak band of moisture passing just north. As a result, windward rainfall has been modest today. Sea breezes have triggered a few showers over sheltered leeward slopes from Kauai to to Maui, and as is typical in the summer, more extensive and briefly heavy shower activity has flared over leeward Big Island.

Easterly trade winds will remain somewhat suppressed tonight and will begin a gradual increase Monday afternoon. The incoming band of moisture will produce showers along mainly windward slopes tonight, possibly into early Monday morning on Kauai. Leeward shower activity will decrease during the evening as lingering convection dissipates and gives way to land breezes. Aside from trailing moisture over Kauai, showers should be less active on Monday as a drier and more stable airmass moves in from the east.

Trade winds will become locally breezy by Tuesday as high pressure builds far north of the state. A typical summertime weather pattern is expected into next weekend. Rainfall will be largely focused over windward slopes, while afternoon showers develop each afternoon over leeward Big Island. A ridge aloft will maintain stable conditions.

AVIATION. VFR conditions prevail at most TAF sites this afternoon. Periods of MVFR conditions are expected through the evening hours for portions of the leeward Big Island slopes where locally heavy showers are occurring. There may be some brief MVFR conditions through the overnight hours over windward slopes of all islands.

MARINE. Light to moderate east-southeast winds will hold tonight as a weak trough west of Kauai continues westward away from the state. A return of a more typical trade wind pattern is anticipated Monday with winds reaching the moderate to fresh range. Winds should ramp up to fresh to strong by Tuesday, likely requiring a Small Craft Advisory for the typical 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. Seas will also approach advisory level (10 ft) over the Alenuihaha Channel and waters south of the Big Island by the end of the week.

Surf along south facing shores will remain small through the week, with mainly a mix of small south and south-southeast energy. For the extended, guidance depicts a a solid area of gales setting up in the Tasman Sea through the first half of the week, which could result in an uptick in surf locally by mid-month.

Surf along east facing shores will remain small through Tuesday, then gradually trend up through the rest of the week as the trades increase locally and upstream of the islands across the eastern Pacific. Surf along north facing shores will remain small through the upcoming week.

HFO WATCHES/WARNINGS/ADVISORIES. None.

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.
