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.

~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Sunday comments:  I’m back on Maui, where skies have turned voggy, with the high clouds having turned a pretty pink at sunrise

Weather Wit of the day: Graduation Forecast – “A brainy day”

>>> Highest Temperature Saturday, November 29, 2025 – 88 near La Puerta, Texas
>>> Lowest Temperature Sunday, November 30, 2025 – minus 26 near Poplar, MT

 

KEY POINTS: Extra Large Swell

  • An extra large west-northwest to northwest (300-320 degree) swell is expected to rapidly fill in Saturday evening and peak Saturday night into Sunday, and will likely produce giant surf along north facing shores and along west facing shores. This could lead to coastal and harbor impacts across exposed north and west facing shores, especially during the high tides.

  • Expect ocean water surging and sweeping across beaches creating the potential for impacts to coastal properties and infrastructure, including roadways. Powerful long shore and rip currents will be present on most beaches.  Large breaking waves and strong currents may impact harbor entrances and channels causing challenging boat handling.

Hawaii’s Broad Brush Weather Overview: An approaching weak cold front will stall just northwest of Kauai and continue to keep the high pressure ridge entrenched directly over the Hawaiian Islands. Large scale stability under this ridge, and drier southeasterly wind flow will minimize shower activity into Tuesday.

Another cold front will approach the islands from the northwest Tuesday. Clouds and showers along the frontal band may stall over Kauai by Wednesday, increasing shower activity over the Garden Isle.

Trade winds will build back into the region and strengthen from Thursday onward, bringing back periods of passing showers to windward and mountain areas, favoring the typical overnight to early morning hours.

Hawaii’s Weather Details: Satellite imagery shows a weak cold frontal system approaching the islands from the northwest, and a weak high pressure ridge over the Hawaiian Islands. Bands of high level cirrus ice crystal clouds, associated with this approaching system are passing over the island chain. The low level stratocumulus clouds near the islands appear very stable with little rainfall expected under the stable subsidence of the ridge anchored directly over the state.

The subsidence temperature inversion heights, as measured by weather balloon observations from Lihue and Hilo, are hovering between the 5,000 and 6,500 feet elevation level. This temperature inversion will continue to serve as a stable capping force for cloud development, reducing shower potential.

Additional stable dry trends are also due to southeasterly wind flow, that places the smaller islands in a drier rain shadow of the Big Island, with clouds tracking more parallel to island mountain ranges, limiting orographic lifting of clouds over windward mountains. Lighter large scale winds will also keep daytime onshore sea breezes going for most areas through Tuesday.

VOG (Volcanic emissions) from the Kilauea Volcano will also ride into all islands on these drier southeasterly winds. This VOG will appear as haze affecting all islands today, with some decreasing trends from Monday onward as the low level steering winds begin to change.

This dry southeasterly wind pattern will continue for most areas through Tuesday or Wednesday. On Wednesday, model solutions are showing changes in our local weather pattern, as a weakening cold front moves into Kauai and stalls. Shower activity will likely increase over Niihau and Kauai for 24 hours, until this front breaks apart and drifts westward away from the islands.

A high pressure system will build in north of the state for the second half of the week, increasing easterly trade winds across the region. Expect some southeasterly winds to linger on Thursday, with winds becoming more easterly and stronger from Friday through next weekend. As the ridge over the islands lifts northward, our typical trade wind shower activity returns with brief passing showers forecast along windward and mountain areas, favoring the typical overnight to early morning hours.

Fire weather:  Rather dry conditions are expected to persist through Tuesday. Winds will be light and variable under a stable land and sea breeze pattern, preventing critical fire weather thresholds from being approached. With the inversion holding around 6,500 ft, very dry conditions will persist on the upper elevations of the Big Island and Maui.

Hawaii’s Marine Environment: A high pressure ridge will remain over or just north of the state through Tuesday, and maintain light to moderate southeast background flow. This pattern will allow for nocturnally driven sea breeze/land breezes along waters adjacent to the islands coasts. By Wednesday, a front will approach Kauai from the northwest, but models show it weakening into a trough then retreating to the west. Typical easterly trades are finally forecast to return late in the week into next weekend, as surface high pressure builds to the northeast of the area.

A series of large to extra large west-northwest to northwest swells will pass through the waters over the next several days. The current long period west-northwest swell (300-320 degree) continues to peak at an impressive 15-17 feet, as noted on the latest Waimea Bay Buoy observations. A Small Craft Advisory will remain in effect through noon on Monday, for marine zones with exposed waters for high seas. This swell is expected to slowly lose energy through tonight, but continue to produce surf above warning criteria.

Thus, the High Surf Warning will remain in effect through noon on Monday for exposed north and west facing shores of most islands. Surf should drop down to advisory levels by Monday afternoon as the swell energy eases. Another large, long period northwest swell (310-330 degree) is forecast to fill in on Wednesday, peak Thursday, then slowly subside on Friday. Surf may once again approach warning levels.

East shore surf will remain small through the weekend due to weak winds. Select south facing shores could experience westerly wrap from this weekend’s large west-northwest swell passage.

Interesting: Threatened Reptiles and Frogs are Disappearing – and What We Have to do

Australia is home to extraordinary reptiles and frogs, from giant lace monitors to tiny alpine froglets. More than 1,100 reptiles and 250 frog species are found across the Australian continent and islands. But we are losing them.

So far, one of Australia’s reptiles has become extinct, the delicate Christmas Island forest skink. And seven frogs are thought to be lost forever, including the only two species of gastric brooding frog – famous for their ability to brood their young in the female’s stomach.

We wanted to know how are other frogs and reptiles were faring. So, for the first time, we asked frog and reptile experts to contribute to the Threatened Species Index (TSX). This index uses robust and reliable data to measure changes in the relative abundance of Australia’s threatened and near-threatened species.
