Detailed Forecast

Synopsis

Moderate easterly trade winds continue through tonight before weakening Friday through early next week. Conditions remain fairly stable with clouds and passing showers over windward and mauka areas.

Discussion

High pressure far north-northeast continues to drive moderate trade winds across the islands. Conditions early this morning remain fairly dry under stable flow with limited clouds and showers over mainly windward and mauka areas. Winds will gradually taper off Friday through Sunday as a front approaches then stalls and weakens northwest of Kauai. Winds shift out of the south by Sunday into next week, but will be light enough for localized daytime sea breezes and nighttime land breezes. Conditions should remain fairly stable with clouds and passing showers over windward and mauka areas.
Another front is expected to approach the state from the northwest early next week. This will keep light wind and stable conditions through at Wednesday. Guidance continues to show a stronger front reaching Kauai around Thursday then either stalling or slowly moving across the state into Friday. Will see better rain chances across the islands during this time but rainfall looks to remain limited along the frontal boundary.

Aviation

Moderate northeast trades will continue through Friday. Shower activity will be minimal with any showers that fall favoring the windward and mountain slopes.
No AIRMETs are in effect.

Marine

Moderate to fresh northeast winds will linger through the rest of the week as high pressure builds north of the area. Winds may ease into the weekend and into early next week with a potential front passing to the north. A Small Craft Advisory is in effect through tonight for the Alenuihaha Channel.
Surf along north and west facing shores through tonight should remain small due to a mix of a medium- period north- northwest swell and a shorter period north-northeast swell. A large to extra large long- period west- northwest swell will build Friday driving surf heights to High Surf Warning (HSW) level criteria late Friday into early Saturday as it peaks. Expect the potential for periodic overtopping of vulnerable coastal roadways, wave runup to coastal properties especially around high tide early Saturday morning and rip currents. A Small Craft Advisory coinciding with the HSW will be needed for the majority of the coastal waters due to seas 10 feet or greater. A gradual downward trend will follow over the weekend, with surf potentially dipping below the advisory levels by the end of the weekend. Due to the westerly component of this swell it will allow west-facing Big Island surf to reach High Surf Advisory (HSA) criteria of 8 feet Friday night through Saturday.
Surf along east facing shores will remain elevated through the weekend due to the lingering short-period north-northeast swell. Surf along south facing shores will remain near seasonal averages for the rest of this week, driven by a mix of short-period southeast and background long period south-southwest swells. An upward trend is expected this weekend through the first week of December, due to an active pattern evolving within our swell window near New Zealand.

Fire weather

Critical fire weather conditions not expected through early next week as winds remain below critical thresholds. Daytime relative humidity may briefly touch critical over drier leeward zones into next week.

HFO Watches/Warnings/Advisories
