Glenn’s Thursday comments:  I’m here at home in upper Kula, Maui

It’s mostly clear here in Maui County early this morning with just a few low clouds, with a chilly low temperature of 49.5 degrees at my place, with the relative humidity 75 percent.

I had more fun this morning playing Pickleball in Makawao! It’s a very calm and sunny afternoon, and with no rain in sight.

452pm, it’s quite voggy late this afternoon!

821pm, it’s clear here in Maui County, in contrast to the rainy weather in certain parts of the Big Island. Here at my weather tower, the temperature has already dropped to cool 52.8 degrees, with the relative humidity unusually low at 55%. It’s going to be a very cool night in those areas with higher elevations.

Monthly Precipitation Summary
Month: December 2025
Prepared: January 8, 2026

Headline: A tale of two halves of the state: Rainy Kauai and Oahu with dry Maui County and the Big Island. Plus, some interesting calendar year stats.

December began with dry and stable conditions, as light southeasterly winds and localized land and sea breezes prevailed ahead of an approaching front. That weak front stalled near Kauai on the 3rd, bringing showers embedded in southerly flow to Kauai and Niihau into the 4th. High pressure rebuilt northeast of the state as the front retreated back to the west, allowing east to east-southeasterly trade winds to strengthen, with typical scattered windward and mountain showers. Winds weakened and veered southeasterly to southerly again around the 8th and 9th as another front approached. The front brought a wetter pattern statewide through the 11th, followed by cooler northerly winds in its wake.

The most significant weather of December occurred around mid-month. A stronger front approached on the 12th, bringing breezy south to southwest winds and pre-frontal showers. The front moved through Kauai and O?ahu on the 13th and 14th before stalling and retrograding westward through the 15th. After a brief lull on the 16th, a shortwave trough destabilized the atmosphere through the 20th, leading to another extended period of steady rainfall over Kauai and O?ahu. Combined totals over the week were around 3 to 6 inches on Kauai (locally up to 7 inches) and 4 to 8 inches on O?ahu, with isolated amounts near 10 to 14 inches along the Koolau Range and northern Waianae Mountains. Rainfall rates were mostly moderate though, with mainly urban roadway flooding impacts, many instances of which were exacerbated by poor drainage maintenance. Two water evacuations occurred on windward O?ahu (Ahuimanu and Kaneohe), along with one water rescue in the Kalihi area of Honolulu. Maui County and the Big Island were largely spared from this event, remaining under drier southeast flow.

Trade winds gradually returned from the 21st to the 23rd, bringing more stable conditions. Moisture from a remnant front was pushed southward during this period, enhancing showers along windward slopes, with rainfall totals around 1 to 2 inches on most islands.

Drier and locally breezy trades prevailed through Christmas Eve and Christmas Day, followed by weakening winds and a shift back toward an east-southeasterly direction ahead of another front. The month ended with moderate trades and generally dry conditions. A brief surge of moisture on the morning of the 30th slightly enhanced windward showers, but no significant impacts were reported.

 

Hawaii’s Broad Brush Weather Overview: Light winds will prevail over the next several days, as a surface ridge axis remains stretched across the islands. Thus, expect the sea breeze regime to continue, with some clouds and showers developing over the interior of the islands each afternoon, then clearing at night.

A cold front will approach the islands from the northwest Sunday night and bring a line of showers quickly down the chain on Monday. A much drier airmass moves in right behind the front, bringing a seasonable chill to the air late Monday into early Tuesday. Another, possibly stronger, frontal system could affect the islands by the middle of next week.

Hawaii’s Weather Details: A surface ridge anchored across the islands has once again allowed for light background flow with afternoon sea breeze development. In general, scattered clouds and isolated showers were sparse and limited to mainly interior regions of the islands. However, a patch of deeper moisture did manage to affect eastern portions of the Big Island, bringing greater shower coverage. A handful of sites in that region reported rainfall totals, since midnight, of just over half an inch. This area of enhanced showers will likely hang around until this late this evening, then wane overnight.

Friday into Saturday, a frontal system is forecast to stall then dissipate just north of Kauai, with winds around state remaining light and variable. Residual moisture from this dissipating feature could bring a brief increase in shower activity over Kauai and to a lesser extent Oahu. Elsewhere, expect fair skies with isolated afternoon showers over the interior regions. Skies should clear overnight with the loss of daytime heating.

On Sunday, latest runs of both the GFS and ECMWF models deepen an upper level trough north of the state, and show a pronounced cold front approaching the island from the northwest. In response, the light to locally moderate flow will turn south or southeasterly. With model timing being nearly identical, confidence is increasing of a surface frontal passage down the island chain during the day Monday.

Along and ahead of the front, a band of steady rain will likely push through. However, due to the quick moving nature of the front, not expecting much in the way of flooding concerns. Immediately behind the frontal passage, breezy northwest to north winds will carry in a cooler and drier airmass. Northerly winds behind the front will quickly veer to more typical northeast trades by Tuesday.

In the extended, late Wednesday into Thursday of next week, both the GFS and ECMWF models indicate yet another frontal passage through the island chain from the northwest. If current trends hold, this system would be stronger than the previous and may bring a period of heavy rain and gusty winds.

Hawaii’s Marine Environment: High pressure ridge will drift south over the central waters due to an advancing front to the northwest, as light to gentle southeast to southerly winds will rule over the marine waters through Friday. The front will dissipate over the northwest offshore waters Friday, as gentle east to southeast winds will prevail Saturday into early Sunday, as the remnant front drifts northward, giving way to southerly winds again late Sunday. Due to the light winds, land and sea breezes are possible through the weekend. A stronger front will move down the island chain Monday and Tuesday, likely bringing fresh northerly winds in it wake.

Surf along north facing shores will remain small to moderate, due to a gradually declining west-northwest swell through Friday. A storm low deepening south of the Aleutian Islands will generate a larger north-northwest (330 degrees) swell, that will build rapidly on Saturday and peak through Sunday, producing surf near High Surf Warning (HSW) levels along north and some west facing shores. Another storm low is expected to develop closer to Hawaii this weekend and generate a larger long period northwest (320-330 deg) swell. This swell will likely produce surf above the HSW thresholds late Monday and Tuesday.

Surf along east facing shores will continue to decline through the weekend, as winds over and upwind of Hawaii remain weak. Some increase in east shore surf is possible early next week. Along south shores, surf will remain very small through the forecast period.

Interesting:  After Devastating Wildfires, Watersheds Surprisingly Thick With Fish and Amphibians

In the aftermath of historically severe wildfires in 2020, a study of Cascade Range watersheds found that stream vertebrates are doing surprising well, highlighted by flourishing fish populations.

“Our work looked at the three years following megafires in western Oregon and suggests that fishes are thriving and amphibians are persisting,” said Oregon State University postdoctoral researcher Allison Swartz, who led the study.

Swartz and collaborators at OSU, the National Council for Stream Improvement, Inc., the U.S. Forest Service’s Pacific Northwest Research Station and the U.S. Environmental Protection Agency examined 30 watersheds in moist conifer forests on the western slope of the Cascades.
