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 Aloha Friday comments:  I’m here at home in upper Kula, Maui

It’s mostly clear here in Maui County early this morning, with a chilly low temperature of 49.5 degrees at my place, with the relative humidity 70 percent.

230pm, it’s turned partly to mostly cloudy, and the volcanic haze (vog) continues this afternoon.

510pm, variably cloudy here on Maui, with still the thick vog hanging around, and I doubt it will clear away anytime soon…unfortunately.

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

 

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 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:  A dying frontal system north of the area will maintain light winds and mostly dry weather through Sunday. Sea breeze development during the afternoons may help generate a few spotty showers over the interior regions of the islands.

By late Sunday, a frontal system will approach Kauai from the northwest, then spread down the island chain during the day on Monday. A line of steady rain will accompany the front, however the flooding threat appears low. Behind the front, expect breezy north winds and a cooler and dryer airmass. Another cold front looks to affect the islands by next Thursday, well after all, it is winter.

Hawaii’s Weather Details:  Satellite imagery showed a band of low and mid level clouds associated with a broad east-west oriented stationary front laying just north of Kauai. Moisture with this feature was relatively shallow. Nonetheless, the added moisture, along with sea breeze development, allowed for a few light showers to develop over mainly interior regions of Kauai and Oahu. Elsewhere, pockets of residual moisture led to scattered showers over the south slopes of the Big Island today.

By Saturday, whatever moisture is left over from the aforementioned front will have mostly fizzled away. Light winds should once again dominate the islands weather picture, prompting afternoon sea breezes and spotty interior showers across the state. High pressure ridging aloft over the islands should act to limit shower development.

Sunday, a deepening upper level trough in the Central Pacific will push a front toward the area from the northwest. Models are in very good agreement on the timing with the front crossing Kauai and Oahu Monday morning, then continuing down the island chain through Maui County in the afternoon. A band of moderate showers will accompany the front, but the flooding threat appears low.

By nightfall, guidance indicates the front stalling and weakening near the Big Island. Immediately behind the front, there will be quite a noticeable airmass change, with breezy north winds bringing in cooler and dryer weather…with low temperatures dropping down into the mid 60’s near sea level. Residents may need to wear two aloha shirts/blouses to keep warm during the chilly weather! Trades resume behind the front Tuesday into early Wednesday, as surface high pressure builds back north of the region.

By late Wednesday, both the GFS and ECMWF models bring yet another cold front down to approach the islands from the northwest. Ahead of the front, winds will veer southerly and increase in strength. Both models agree on timing with the front and move it quickly down the island chain during the day Thursday. Once again, expect a period of steady rain along and head of the front, with a cooler and dryer airmass behind the front. High pressure builds back in Friday with a return of typical trade flow into next weekend.

Hawaii’s Marine Environment: A high pressure ridge over the central waters will remain stationary, as a cold front approaches from the northwest. Light to gentle southeast to southerly winds will prevail over the marine waters. As the front dissipates and its remnants lift northward, gentle east to southeast winds will prevail Saturday and early Sunday, giving way to southerly winds again late Sunday. Due to these lighter winds, land and sea breezes are possible through the weekend. A stronger front will move down the island chain Monday and Tuesday, likely ushering in fresh northerly winds in it wake.

Surf along north facing shores will remain small as the west-northwest swell continues to gradually decline. Surf is expected to build in rapidly Saturday with long period forerunners potentially reaching the offshore waters earlier. This large long period north-northwest (330 degrees) swell will likely peak Saturday evening, producing surf near High Surf Warning (HSW) levels along north and some west facing shores. Surf will remain elevated on Sunday before a potentially even larger long period northwest (320-330 deg) swell will build through the day on Monday and hold through Tuesday likely above the HSW thresholds. Surf will likely remain elevated through the middle of next week.

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:  Melting Glaciers Top the List

Climate change, trust in science and health were among the most popular topics covered by UZH media releases and articles in 2025. As in past years, our stories about research at UZH resonated all over the world.

Last year, the UZH media relations team published over 70 media releases and articles about the university’s research findings and institutional developments. As always, not all topics received the same level of attention from national and international media outlets. An internal ranking of the 10 most successful releases shows that, for the first time, UZH’s media releases on climate change topics attracted the greatest attention across the globe.

Alarming Glacial Melt

2025 was the International Year of Glaciers, and the UZH-based World Glacier Monitoring Service (WGMS) put the issue firmly in the spotlight. Fittingly, two UZH media releases on glacier loss received the most attention. Headlines highlighting an increased loss of freshwater resources and ever-rising sea levels resonated far beyond Switzerland. In UZH’s most popular 2025 media release, WGMS director Michael Zemp calculated that glaciers worldwide have lost an average of 273 billion tons of ice annually for the past 25 years. This stark warning was picked up by almost 1,100 national and international media outlets, both online and in print.
