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

It’s mostly clear with a few clouds here in Maui County early this morning, with a low temperature of 52 degrees at my place, with the relative humidity 74 percent. We still have some vog in the air today.

I had a friend over, and we took a good hike up in the Hosmer’s Grove, and were well abovc the clouds along the lower slopes. We had a nice dinner and then a sliver of cake with mint ice cream for dessert. Oh yeah, we popped a bottle of Mumm’s Champagne, and each had 2 flutes…which was a tasty Rose.

Now, at 947pm, skies are cloud free with a million stars shining down, although by far, Jupiter is the brightest feature in the sky tonight. The temperature here at my place in upper

Interesting Web Blog…Mauka Showers – Rainfall from the (Sort of) Kona Low of January 4-6, 2026

 

Monthly Precipitation Summary (NWS)
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 Oahu, 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: Stable and mostly dry conditions are accompanied by light winds through Sunday. A quick-moving cold front then brings a quick hit of showers to the islands late Sunday night into Monday. A second front will bring another round of showers Wednesday night into Thursday with increased potential for heavy rainfall around Kauai Wednesday.

Hawaii’s Weather Details:  Energy coming off of Asia over the next 7 days will reach a mean trough position south of the Aleutians, and then get deflected northward upon encountering a strong ridge along the west coast of North America. Each of these troughs will provide enough upper support to push a surface frontal boundary that is able to approach…if not cross…the island chain on Monday/Tuesday and again on Friday.

The approach of each frontal boundary will be enough to disrupt the trades and bring a more organized precipitation pattern than what is expected from a typical trade wind scenario. Model agreement continued to be above average across the central Pacific into Day 5 / Thursday, before some notable differences open up between the ECMWF and the GFS.

Those differences appear to revolve around the handling of the upper level ridge along the west coast of North America. It is expected that this pattern will continue to support a relatively active pattern over the next 7+ days across the islands.

Hawaii’s Marine Environment: A weak high pressure ridge will remain nearly stationary over the central waters, as a front dissipates over northern waters. Another cold front will sweep from west to east down the island chain on Monday, stalling near the Big Island by Monday night. An even stronger cold front will quickly move through the islands, spreading strong to near gale force winds across the northwestern coastal waters later next week from Wednesday into Thursday. A Small Craft Advisory was issued for Hawaiian Coastal Waters exposed to the large northwest swell…these elevated seas are for waters and channels exposed to this rising northwest swell.

A large northwest swell building through Hawaiian coastal waters will increase surf heights above advisory thresholds. A High Surf Advisory (HSA) was issued for exposed north and west facing shores. Offshore buoy reports show quickly rising seas from this next large northwest (310-330 degree) swell with advisory level surf on the way. Surf heights will swiftly increase for all islands exposed to this rising northwest swell. Swell energy will then hold above HSA thresholds into Monday, as another much larger overlapping northwest (320-330 degree) swell swiftly builds surf to High Surf Warning levels potentially from Monday through Tuesday. Yet another extra large swell will build into the islands by late Thursday, potentially producing another round of warning level surf along exposed north and west facing shores.

Surf along east facing shores will remain small through this weekend as winds over and upwind of Hawaii remain weak. Some increase in east shore surf is possible early next week, as a cold front moves down the island chain. Along south shores, surf will remain very small through the forecast period.

Interesting:  Exposure to Natural Light Improves Metabolic Health

An international team has provided the first direct evidence of the beneficial effects of scheduled daylight as compared to artificial light in people with type 2 diabetes.

Metabolic diseases have reached epidemic proportions in our society, driven by a sedentary lifestyle coupled with circadian misalignment – a desynchrony between our intrinsic biological clocks and environmental signals. Furthermore, we spend almost 90% of our time indoors, with a very limited exposure to natural daylight.

To investigate the specific role of daylight in human metabolism, particularly in glycaemic control, researchers from the University of Geneva (UNIGE), the University Hospitals of Geneva (HUG), Maastricht University, and the German Diabetes Center (DDZ) conducted a controlled study with thirteen volunteers with type 2 diabetes.

When exposed to natural light, participants exhibited more stable blood glucose levels and an overall improvement in their metabolic profile. These results, published in the journal Cell Metabolism, provide the first evidence of the beneficial impact of natural light on people with type 2 diabetes.

As in all living beings, human physiological processes are subject to the influence of the circadian rhythm governed by the alternation of day and night. This is controlled by a central clock in the brain, which synchronizes the clocks in peripheral organs such as the liver and skeletal muscles.

“It has been known for several years that the disruption of circadian rhythms plays a major role in the development of metabolic disorders that affect an increasing proportion of the Western population,” notes Charna Dibner, associate professor at the UNIGE Faculty of Medicine and at HUG, who co-directed this work with Joris Hoeks, associate professor at Maastricht University, and Patrick Schrauwen, professor at the DDZ.
