~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Aloha Friday comments:  I’m here in Corte Madera, Marin County, California with my friends Linda and Bob.

Bob and I will be driving to Sebastopol in Sonoma County, to buy food and have lunch. We have a week long vacation rental right on the coast…at Sea Ranch. I’ll be up there around 2pm this afternoon Hawaii time. I’ll set up my computer and be back online with updates for you shortly thereafter.

We made it to our vacation rental late this afternoon, and have put our food away and took a very short walk out to the cliff overlooking the large breaking waves…to watch the sunset. We had a shot of vodka to take the edge off the long drive out to the coast. We’re about to put on some music, and we have the fire place going. What a great start to our week long stay here! The pounding surf is loud, so we’ll have to turn the music up pretty loud to hear it…as we keep the sliding glass doors fully open. The temperature is a cool 52.5 degrees here at 524pm CA time / 50.1 degrees at 703pm CA time.

Weather Wit of the day: The fall weather reminds me of a political speech. Y0u get a little sunshine, lots of wind and maybe an occasion snow job.

Monthly Precipitation Summary

Month: October 2025

Headline: October rainfall still largely below average state-wide, despite a better showing for Oahu and Big Island over September’s amounts.

The month began with moderate trades and increased moisture, bringing enhanced windward showers, especially on O?ahu and Molokai. As high pressure weakened between the 2nd and 5th, trades shifted southeast and lightened, allowing land and sea breezes to form. This shifted shower activity to interior and upslope areas, mainly southeast-facing slopes, though rainfall stayed generally light (around a quarter inch or less).

A weakening surface trough lingered over the western half of the state from the 6th to the 10th, bringing higher humidity and periods of light to occasionally moderate showers, most notably on Kauai where isolated totals reached 1 to 2 inches. Light southeasterly winds supported localized heavy rainfall over the southern coastal and upslope areas of Kauai and Oahu during this time. A Flood Advisory was issued for the island of Oahu for rainfall rates of 1 to 2 inches per hour. Moisture decreased after the 11th, though light winds continued to support afternoon inland showers through the 14th.

Moderate to breezy trades returned mid-month along with an upper low near Kauai, producing several days of wetter weather from the 16th into the 21st. Heavy rain prompted the issuance of a Flood Advisory on the Kona slopes of the Big Island on the 16th for rainfall rates of up to 1 inch per hour and for the island of Kauai on the 17th for rates of 1 to 2 inches per hour. A drying trend took hold from the 22nd to 24th as trades strengthened into the breezy to locally strong range, leading to periods of critical fire weather conditions across interior and leeward zones.

Deep tropical moisture was drawn northward into the Big Island beginning on the 24th and spread westward across the state. The heaviest rainfall occurred over windward areas of the Big Island and Maui, while cold temperatures aloft allowed for wintry precipitation on the Big Island summits. Some leeward and higher terrain areas received 1 to 2 inches of rain, prompting a Flood Advisory for Kauai during early morning on the 28th. Trade winds weakened again over the last few days of the month as a front lingered well north of the state. On the 29th, enhanced showers from lingering instability from an upper trough brought heavy rainfall to the Big Island from Hilo around South Point to Kona, triggering a Flood Advisory. Conditions trended drier to close out the month under light to moderate trades.

 

Hawaii’s Broad Brush Weather Overview: Light winds are expected across the state tonight as a front approaches from the northwest. The front will move north to south across the islands chain this weekend, bringing increased rainfall that will be primarily focused along windward slopes. Breezy trades will follow the front, persisting through much of next week.

Hawaii’s Weather Details: Trade winds have been mostly cut off thanks to a broad low pressure system to the northeast, and its associated cold front that is located in the northern offshore waters. Light east-southeasterly background flow prevails across the state, and as a result, daytime sea breezes have increased clouds over island interiors and sheltered leeward locations.

Despite slight weakening of the mid level ridge over the island chain, mostly stable conditions remain in place in advance of the front`s arrival, and showers across the islands have been light. Afternoon atmospheric soundings at Lihue and Hilo continued to show strong inversions between 5,000 and 6,000 feet.

On Saturday, the aforementioned cold front is expected to approach and move over the western end of the state, then make its way down the island chain into Saturday night, and pass over the eastern end of the state sometime on Sunday. Modest low level moisture pooling ahead of and along this boundary will increase rain chances as the front progresses down the island chain.

Breezy trades overrunning the front will focus most of the showers along windward and mountain areas, but some showers may also blow over island terrain to reach leeward areas of the smaller islands as well. Model guidance continues to indicate that, with little to no upper-level support with this system, rainfall rates will likely be limited.

The relative quick-moving nature of the front through the island chain will serve as an additional limiting factor for flooding concerns. With that said, have leaned on the higher end of available guidance for QPF, we could see at least a couple of inches of rain in some locations throughout the weekend (particularly along some windward areas of Maui and the Big Island).

Breezy to windy east-northeasterly trades will become established across the state by Tuesday, as high pressure builds to the north. Another reinforcing front with an even stronger high pressure system will arrive mid-week, providing another boost in the east-northeasterly trades. With mid level ridging persisting over the region, inversion heights will remain low, keeping the moisture confined to lower levels and focusing clouds and showers over windward and mountain areas.

Fire weather: With light winds prevailing ahead of an approaching cold front into Saturday, critical fire weather concerns are not expected. Additionally, increasing moisture is expected with the frontal passage this weekend. Trades are forecast to return and become breezy as the front moves through, then become breezy to windy next week. However, it may be difficult to reach critical relative humidity thresholds.

Hawaii’s Marine Environment: The wind flow will become light and variable as an area of low pressure moves north of the Hawaiian Islands, and an associated cold front approaches from the northwest. The front is forecast to pass across the island chain late Saturday into Sunday. Behind the front, expect fresh to locally strong north-northeast winds to fill in. These winds should last into early to mid next week as high pressure builds north of the state. Small Craft Advisories will likely be needed during this time.

The current small to moderate, medium period, northwest swell (320-330) will slowly subside through early Saturday, and keep surf size near seasonal norms along north facing shores. A deep low pressure system will pass well north of the state, with a north to south fetch pointed directly towards the islands. This low will generate a large, short to medium period, northerly swell that will help to bump surf heights up late Saturday into Sunday, that will likely exceed the High Surf Advisory threshold for north facing shores. This fetch will also favor harbor surges in north facing harbors such as Kahului and Hilo on Sunday. Additional north-northeast swell should continue elevated swell conditions along north and east facing beaches through early next week.

Surf will remain small along east facing shores as trade flow weakens to light and variable. As a cold front presses southward across the island chain Saturday into Sunday, winds will shift northeasterly and increase in strength. This, combined with a large, moderate period, north or north-northeast swell will bring high surf and choppy conditions to east facing shores late Saturday through Monday. A High Surf Advisory will likely be needed during the peak of the event.

A small, long period, south-southwest swell will boost surf heights later into Saturday to near seasonal norms along south facing shores. Several more similarly sized southerly swell will enter the waters Sunday into early next week.

Peak monthly tides combined with water levels that are running higher than predicted will lead to minor flooding along the shoreline and in low-lying coastal areas for the next several mornings. Thus, the Coastal Flood Statement has been extended through noon Saturday.

Interesting:  Wildfire Risk Making Timberland Less Valuable, Long Harvest Rotations Less Feasible

Rising wildfire risk in the Pacific Northwest combined with notoriously volatile timber pricing may lower forestland values by as much as 50% and persuade plantation owners to harvest trees much earlier than planned, a new analysis of Douglas-fir forests shows.

Rising wildfire risk in the Pacific Northwest combined with notoriously volatile timber pricing may lower forestland values by as much as 50% and persuade plantation owners to harvest trees much earlier than planned, a new analysis of Douglas-fir forests shows.Under the worst-case scenarios, modeling by researchers at Oregon State University suggests harvesting trees at 24 years would make the most economic sense. Absent wildfire risk, the optimal age would be 65 years.Generally, private landowners harvest between those two ages, but it’s not a surprise for the optimal rotation age to go down in these scenarios, the scientists say.
