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.

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

Clear with light winds and vog in the morning here in Maui County, along with very large surf on the north and west shores…which was wrapping around some south shore beaches.

It’s cloudy here in Kula, and we’re getting a very nice light shower!

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

>>> Highest Temperature Sunday, November 30, 2025 – 87 at Naples, Florida
>>> 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: A trough northwest of Kauai will maintain a ridge over the islands, resulting in minimal shower activity and light southeasterly winds. Another front will approach and stall northwest of Kauai on Tuesday, bringing clouds and showers to the western end of the island chain Wednesday. More typical trade wind weather with showers favoring windward and mountain areas will become reestablished Thursday into next weekend.

Hawaii’s Weather Details: A surface and upper level ridge over the islands is maintaining light southeasterly flow with a stable airmass in place. This result is localized land and sea breezes and minimal shower activity. The surface ridge has been pushed over the islands due to a trough to the northwest, which is expected to weaken and be pushed to the northeast by another front currently far to the northwest of the Hawaiian islands.

The GFS and ECMWF models are in good agreement with this next front approaching from the northwest Tuesday. Both models bring pre-frontal convergence bands to the northwest of Kauai Tuesday night. The GFS stalls the front to the northwest of Kauai, while the ECMWF brings the front over the Garden Isle, with additional moisture being drawn northward over the Oahu and parts of Maui County. For now the forecast falls more in line with the GFS, in keeping the bulk of the shower activity west of Kauai.

The global models have some significant differences during the second half of the week. Both models show the front dying and being replaced by a surface trough. The GFS goes on to form a low pressure system along the trough, west of the islands, with the low moving to the west. The GFS also develops a strong upper level low in conjunction with the surface feature. The ECMWF is slower to develop a low along the trough, and when it does so, it develops one north of the islands that lifts northward.

While the models show significant differences during the second half of the week, they remain in decent agreement with a ridge north of the islands allowing trade winds to build back in over the islands. Accompanying the trades would be showers focused over the windward and mountains areas.

The upper level feature from the GFS could spell increased winds over the Big Island Summits Thursday on through the weekend. Currently, the forecast keeps winds below advisory levels for the summits, however we’ll have to watch future model runs to see how things may play out.

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.
