Hawaii’s Mountains – Here’s a link to the live webcams on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii, and atop the Haleakala Crater (~10,023 feet) on Maui. These webcams are available during the daylight hours here in the islands, and at night whenever there’s a big moon shining down. Also, at night you will be able to see the stars, and the sunrise and sunset too…depending upon weather conditions.

Glenn’s Sunday 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 chilly low temperature of 49 degrees at my place, with the relative humidity 52 percent.

1221pm, mostly sunny, with just a few popcorn cumulus clouds floating around in the light breezes

440pm, mostly sunny to partly cloudy, with some generally light kona breezes, which at times are a bit more than that here in upper Kula. The temperature here at my place is 65.8 degrees with the relative humidity an unusually low 53%. I’m starting to get excited as see this next cold front getting closer to the state!

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 Oahu 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 Oahu. 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 Oahu (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: Changes are on the way as two cold fronts will move through the state this week. The first will bring showers and northerly winds tonight into early Monday. Showers should linger Tuesday as the remains of the front move back west over the state. The second front arrives Wednesday night into Thursday, bringing another round of showers and even stronger winds. Pre-frontal winds Wednesday afternoon could be quite gusty. The week should end cool and fairly dry with trades re-established.

Hawaii’s Weather Details:  A few showers have popped on Oahu, but rainfall amounts have been limited to just a few hundredths as the atmosphere remains relatively stable. Otherwise, skies were clear to partly cloudy on most islands and winds were light out of the south through southwest at most locations…otherwise known as Kona winds.

A cold front is moving toward Kauai County, and will move through much the state overnight and early Monday, before stalling near the Big Island late Monday. Moderate to occasionally heavy showers will accompany the front, and winds will become northerly after passage. Tuesday morning low temperatures will be around 5 degrees below normal due, to the dry air coming in with the front. By Tuesday afternoon, winds will swing rapidly around to easterly and then southeasterly, as the front begins to move back west over the state. Additional showers will form as this occurs.

Wednesday, a new cold front will approach from the northwest. As front nears the state, we will have a period of strong south to southwest surface winds over the smaller islands. Gusts of 25 to 35 mph are expected Wednesday afternoon, especially over higher terrain and just downwind (what is normally windward will briefly become leeward during this period of southwest surface winds).

Weather headlines for wind may be needed as we get closer in time. The front is forecast to get to Kauai County around sunset, Oahu in the evening, Maui County before sunrise, and Big Island by noon Thursday. This will bring another round of showers, some possibly strong. Fast movement through the state should limit the risk of flooding.

Friday and Saturday will be cool as relatively dry air moves in behind this second front. Trades will build back in, pushing the remnants of the front south of the state. Showers should be limited as this prevents the moisture from passing back over the state, as with the first front earlier in the week.

Hawaii’s Marine Environment: A weak high pressure ridge will remain nearly stationary over the central waters. This pattern changes on Monday, as a cold front sweeps down the island chain from west to east, stalling near the Big Island by Monday night. By Wednesday an even stronger cold front will quickly move through the islands, spreading strong to near gale force winds across the northwestern coastal waters Wednesday into Thursday. A Small Craft Advisory remains in effect for Hawaiian Coastal Waters exposed to the large northwest swell, these elevated combined seas are forecast to linger over waters and channels exposed to this northwest swell energy.

A High Surf Advisory (HSA) was extended in time through Monday morning, for north and west facing shores exposed to the large northwest swell energy. This swell will hold above HSA thresholds into Monday as yet another much larger overlapping northwest (320-330 degree) swell swiftly builds surf to High Surf Warning (HSW) levels from Monday through Tuesday. An HSW will likely be issued on Monday to cover this next warning level surf event. Yet another extra large northwest (320-330 degree) swell will build into the region by Thursday, potentially producing another round of warning level surf along north and west facing shores lasting through Friday. This northwest swell energy will diminish into next weekend.

Surf along east facing shores will remain small through the first half of this week, due to a continued disruption in the trade wind flow. Surf heights will remain very small along south facing shores through the forecast period

Interesting:  ‘Forever Chemicals’ May Triple Risk of Fatty Liver Disease in Adolescents

A study co-led by researchers at the University of Hawaii at M?noa has found that exposure to per- and polyfluoroalkyl substances (PFAS)—commonly known as “forever chemicals”—may significantly increase the risk of metabolic dysfunction-associated steatotic liver disease (MASLD) in adolescents. MASLD affects about 10% of children and up to 40% of children with obesity and can increase long-term risk for type 2 diabetes, heart disease and liver cancer.

The findings were published in Environmental Research and is a collaboration with the Southern California Superfund Research and Training Program for PFAS Assessment, Remediation and Prevention Center.

PFAS are synthetic chemicals used in nonstick cookware, stain- and water-repellent fabrics, food packaging and some cleaning products. They persist in the environment and accumulate in the body over time. More than 99% of people in the U.S. have measurable PFAS in their blood, and at least one PFAS is present in roughly half of U.S. drinking water supplies.
