~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Saturday comments:  I’m here at Sea Ranch, CA with my friend Bob.

It’s clear this morning here at the coast, and I’m looking out to the breaking large waves. The wind is offshore, so there is lots of spin drift (spray) coming off the tops of the waves as they break.

It’s a very warm day here on the coast, at least on the sunny side of the house, with a cooler 57 degrees on the shady side. There’s very little wind, with a glassy ocean surface as far as I can see.

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: A cold front will move down the island chain through Sunday, bringing an increase in showers, especially along windward slopes. Breezy to windy east-northeasterly trades will fill in behind the front and persist through much of next week, as strong high pressure builds north of the islands. Typical windward and mountain showers will prevail under the trade flow, with generally drier conditions leeward.

Hawaii’s Weather Details: Satellite imagery shows a cold front approaching the western end of the state, with light winds and isolated to scattered light showers in advance of the boundary. The front is expected to reach Kauai by mid-morning, Oahu later this afternoon or evening, and progress down the island chain to the Big Island by early Sunday morning. Light and variable winds will prevail ahead of the front, shifting to breezy to windy east-northeasterly trades in its wake.

Moisture pooling along and just ahead of the boundary will bring an increase in showers as it moves southeast, primarily affecting windward and mountain areas, but some showers may also blow over island terrain to reach leeward areas of the smaller islands as well. Mid-level ridging in place over our area will act to limit vertical development, keeping rainfall rates modest overall.

In addition, the relatively quick-moving nature of the front will also help to limit flooding concerns. However, model guidance is still showing that certain windward areas (particularly across Maui County and the Big Island) could receive a couple of inches of rain Saturday evening through Sunday.

Breezy to windy east-northeasterly trades will become established across the state early next week 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: Critical fire weather conditions are not expected through the forecast period. Winds will remain light across most of the state ahead of the approaching front, with elevated relative humidity values. The front will reach Kauai later this morning and make it to the Big Island by sometime Sunday morning. Breezy to windy trades are forecast to fill in behind the front and persist through next week, but low-level moisture embedded within the trades will help keep relative humidity from reaching critical thresholds.

Hawaii’s Marine Environment: A cold front will press southeast and proceed down the island chain through Sunday. Fresh to locally strong north-northeast winds will develop in the wake of this front along with building seas. A Small Craft Advisory for both winds and seas will likely be needed for most marine zones tonight and beyond to account for these hazardous conditions. Northeast winds are forecast to remain fresh to strong through mid next week, as high pressure builds north of the area.

The current small to moderate, medium period, northwest swell (330 degrees) will remain steady and keep surf near seasonal averages along north facing shores. A north to south oriented fetch, generated from a gale force low far north of the state, will send a large, medium period, northerly swell our direction. This swell will help build surf heights to near or above High Surf Advisory thresholds along north facing shores tonight through Sunday. This swell will also favor harbor surges in north facing harbors such as Kahului and Hilo on Sunday. Moderate to large north-northeast swells will keep surf elevated along north facing shores through at least early next week.

Light and variable winds will maintain small surf along east facing shores. As the front moves down the island chain through Sunday, winds will shift northeasterly and increase in strength. This, combined with a large, moderate period, north-northeast swell (010-030 degrees) will bring elevated surf and choppy conditions to east facing shores through at least early next week. A High Surf Advisory may be needed during the peak of the event.

A small, long period, south-southwest swell will keep surf heights near seasonal averages along south facing shores. Expect a bump in south shore surf Sunday through mid next week, as a couple more small, long period, south swells arrive.

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 during high tide.

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.Read more at: Oregon State UniversityDouglas-fir forest.
