Hawaii’s MountainsHere’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.

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 being accompanied by light winds through today. A quick-moving cold front then brings a brief hit of showers to the islands late tonight 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:  Stable conditions with fair weather will continue today, with sea breezes developing by late morning. Clouds and a few light showers will be possible this afternoon, but overall mostly dry conditions are expected during the day.

Starting tonight, a cold front will begin to approach Kauai, and we will begin to see showers increasing ahead of the front, with moderate southerly winds. Models are in very good agreement on the timing with the front pushing through Kauai tonight, Oahu on Monday morning, and Maui County Monday afternoon and evening, and then weakening and stalling around the Big Island Monday night. With the main instability expected to stay north of the state, the threat for flash flooding will be low, but we should see a brief increase of moderate showers along the frontal boundary.

Immediately behind the front, there will be quite a noticeable airmass change, with breezy north winds bringing in cooler and drier weather. Dewpoints should drop into the mid to upper 50’s Monday night for the smaller islands, with low temperatures dropping down into the low to mid 60’s near sea level. Tuesday morning will start off chilly by Hawaii standards, but should be a fair weather day with plenty of sunshine across the smaller islands. Some lingering moisture will be possible across windward Big Island Tuesday.

Starting Wednesday, we will see another cold front approaching the island chain from the northwest. This front looks to be stronger than the first front, with breezy to strong kona winds developing ahead of the front. We could see a brief period of some gusty winds on the lee side of any terrain Wednesday into Wednesday evening. With the front being stronger, we could see periods of moderate to locally heavy showers along the frontal boundary and also ahead of it.

For Wednesday, shower activity will be most active over the western half of the state with showers increasing over Maui County Wednesday night into Thursday. By Thursday morning, drier conditions are expected over the western half of the state, with a few showers still lingering around Oahu in the morning. Once again, a cool air mass will follow behind the front, which should make temperatures colder than normal Thursday into Friday.

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.
