Area Forecast Discussion National Weather Service Honolulu HI 835 PM HST Mon Jan 20 2020

SYNOPSIS. Trade winds will diminish and veer southeast tonight, with daytime sea breezes and overnight land breezes prevailing Tuesday through Friday. Mostly dry pattern expected through the remainder of the work week, with only a few clouds and showers developing over interior and mountain areas each afternoon. A front is expected to stall and weaken near Kauai Friday night, with trades then returning over the weekend.

DISCUSSION. High pressure northeast of Hawaii is moving away to the east as a front approaches from the northwest. Winds will begin to weaken and veer southeasterly by Tuesday as the front forces the ridge associated with the high over the state, allowing a land and sea breeze regime to setup through Friday. Rain chances will remain limited due to the dry air and strong subsidence expected to continue through this time period. The best chance for a few clouds and light showers will shift over interior areas through the afternoon hours each day. The front will pass well north of our area on Wednesday and will not have any direct impacts to the islands.

A second front will follow during the second of the work week and keep the ridge on top of Hawaii, and our winds light. The front is expected to dissipate as it reaches Kauai late Friday and bring a brief uptick in showers for the northern end of the state Friday night. Trade winds may briefly return Saturday as a bubble high quickly passes north of the state before the winds lighten and shift southeasterly again Sunday ahead of another passing front to the north.

AVIATION. Winds have diminished and will continue to weaken overnight into Tuesday with a relatively weak surface high east-northeast of Hawaii that continues to move away from Hawaii. Northeast trade winds will shift to a more east/southeast direction for most of the state. The winds will be weak enough to create a daytime sea breeze/nighttime land breeze scenario from tonight through Tuesday. The state will also have dry conditions with only a few isolated mauka showers possible through this period. Since the winds will be light and the most of the state is expected to be dry or only have a few isolated showers, no AIRMETs are in effect or expected through Tuesday.

MARINE. High pressure to the north will maintain breezy trade winds tonight before dropping on Tuesday. A Small Craft Advisory (SCA) is currently posted for the windier waters around Maui County and the Big Island due to a combination of breezy trade winds and rough seas. The high will move east over the next couple of days allowing for lighter winds to push across the islands from west to East Tuesday, and then remain light and variable into Friday. A large northwest swell will increase seas above SCA levels starting Wednesday. A new high will bring trade winds back over the weekend.

A current NNW swell is on its way down and will diminish further through Tuesday. A large, long period northwest swell is expected to arrive Tuesday night, peak Wednesday night, then lower into Friday. Latest guidance indicates that surf heights will reach High Surf Warning levels along most north and west facing shores during the peak of this swell. A second large northwest swell is expected to build late Friday, peak on Saturday, then lower through Sunday. Warning level surf is also expected during the peak of this swell.

Small background south swells will remain through the weekend. With the expected drop off in trade winds over the next few days, short period choppy surf will diminish along east facing shorelines. Some south and east facing shores may see localized higher surf from the large northwest swells refracting around islands and reefs.

HFO WATCHES/WARNINGS/ADVISORIES. Small Craft Advisory until 6 AM HST Tuesday for Maui County Windward Waters-Maalaea Bay-Pailolo Channel-Alenuihaha Channel- Big Island Windward Waters-Big Island Leeward Waters-Big Island Southeast Waters.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
