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 Monday comments:  I’m here at home through the winter in upper Kula, Maui

It’s clear here in Maui County early this morning…with a chilly low temperature of 49 degrees at my place, with the relative humidity 75 percent.

I’m heading down to Makawao for a session of Pickleball, and will be back early this afternoon with more weather updates.

It’s a wonderfully sunny and pleasant late autumn day here on Maui, with the relative humidity an unusually low 49%

Weather Wit of the day: Rain Free – A forecast meaning, “If you get any, it won’t cost you anything”

>>> Highest Temperature Sunday, December 7, 2025 – 91 at McAllen, Texas
>>> Lowest Temperature Monday, December 8, 2025 – minus 23 near Forest Center, MN

Incredible Lava flow Fountain on the Big Island – December 6th

 

Hawaii’s Broad Brush Weather Overview: Winds will lighten up as a cold front approaches from the northwest. Daytime sea breezes and nighttime land breezes expected Tuesday and Wednesday, with the front arriving Wednesday night and dissipating around Maui County Thursday night. Cool north winds briefly follow, then swing around to the south as the next system approaches over the weekend.

Hawaii’s Weather Details: A moderately strong high is centered far northeast of the state, driving moderate trade winds across the area. Mostly clear skies prevail, although expect a few windward showers overnight and Tuesday morning, as winds taper off due to an approaching front from the northwest.

Afternoon sea breezes will set up over all islands on Tuesday, as the ridge of high pressure backs off and the Hawaii islands come more under the influence of the approaching cold front. Land breezes will clear skies Tuesday night, followed by a repeat for Wednesday.

The front will be a thin band of clouds and showers, that will weaken as it reaches Kauai Wednesday night, Oahu Thursday and then dissipates over Maui County Thursday night. Moderate to breezy cool northerly winds will blow in as the front passes through Maui County. The band will diminish and lift northward as high pressure builds in over the state.

Winds will lighten again as the next front approaches from the west Friday and Saturday. The latest long range model guidance shows large inconsistencies on when, or even if this frontal cloud band will bring another round of showers to the state beginning late Saturday night into early next week.

Fire weather: Conditions remain below critical fire thresholds through the week as winds remain light and RH elevated. Temperature inversion heights over Maui and the Big Island will range from 5,500 to 6,500 feet through Tuesday.

Hawaii’s Marine Environment: An area of high pressure will remain north of the Hawaiian islands, producing gentle to moderate easterly winds, then decrease and veer more southeasterly to southerly Tuesday to Wednesday, as the next cold front moves into the area from the northwest. This front may move into the western Hawaiian islands late Wednesday into Thursday, then diminish by Friday.

The current medium period, north-northwest (340-350 degree) swell will continue to slowly fade, bringing surf back down to below average levels for this time of year. The next two long to medium-period overlapping northwest (310-320 degree) swells will arrive, boosting surf along north and west facing shores and possibly reaching advisory levels by Wednesday.

Choppy east shore surf will remain small, then decline further over the next few days as trades gradually ease. Expect minimal background energy for south facing shores, keeping south shore surf heights just above flat levels.

Interesting:  UAlbany Atmospheric Scientist Proposes Innovative Method to Reduce Aviation’s Climate Impact

If you look up at the sky on a clear day, chances are you’ll notice thin, white clouds following behind airplanes— also known as contrails.

The formation of these wispy ice clouds is a complex process that involves the mixing of hot exhaust gases with cold air. Depending on the atmospheric conditions, contrail ice particles can last for a short time or persist for several hours or longer. Before dissipating, they trap heat that would otherwise be released into space, contributing to climate change.

A study that looked at aviation’s contribution to climate change between 2000 and 2018 concluded that contrails create 57 percent of the industry’s warming impact, significantly more than the CO2 emissions from burning fuel.

Fangqun Yu, a senior research faculty at the University at Albany’s Atmospheric Sciences Research Center, has developed an advanced model for simulating contrail formation and published several scientific papers on the formation and properties of contrail ice particles.
