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 in Corte Madera (Marin County, CA) at my friend Linda’s place

It’s cloudy early this morning…with a low temperature of 45 degrees.

I fly back to Maui this morning, and so I’ll begin my updates when I get back home to upper Kula…and get my computer set up this afternoon.

I’m back on Maui, where skies have turned voggy, with the high clouds having turned a pretty pink at sunset.

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

>>> Highest Temperature Friday, November 28, 2025 – 82 near Glamis, CA
>>> Lowest Temperature Friday, November 28, 2025 – minus 4 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: Light southeast winds are expected to remain in place through the next few days. Stable air will keep most areas dry, though daytime sea breezes could increase cloud cover over the islands each day, followed by clearing at night. By the middle of next week, a cold front could increase shower chances over the western islands, as it approaches and moves through. Trade winds are expected to return during the second half of next week.

Hawaii’s Weather Details: Latest satellite imagery shows a deep, large low pressure system far north of the main Hawaiian Islands. Meanwhile, surface high pressure is centered northeast with a ridge axis extending overhead. This ridging has resulted in light southeast background winds prevailing across the state, with stable, dry conditions in place. Due to the light nature of the background flow, daytime sea breezes have increased cloud cover over some interior and leeward locations, but these clouds will clear overnight as land breezes resume.

Little change in the overall weather pattern is expected through the weekend, as a front north of the state approaches, stalls, and dissipates before reaching the islands. Light southeasterly background winds with daytime sea breezes and nighttime land breezes will continue. Rainfall will be scarce, as the ridge overhead will support mostly dry conditions. Additionally, the light southeast flow will continue the potential for vog generated from the recent eruption of Kilauea to spread over the islands for the next few days.

Early next week, an initial cold front will approach the state and stall to our northwest. However, this will quickly be followed by a second front, driven by a strong upper trough approaching on Tuesday. Global models continue to indicate that this front could move through Niihau and Kauai on Wednesday, possibly reaching Oahu and stalling by Thursday.

Should it materialize, breezy northeasterly trade winds will build back into the region and rainfall chances will increase for the middle to late part of next week across the western islands. However, there remains a lot of uncertainty in the long range forecast, and details will become more clear as the time approaches.

Fire weather:  Even though we will see relative humidity levels fall heading into the weekend, weak winds will preclude reaching critical fire weather conditions for the next few days. Temperature inversion heights near Big Island and Maui will range between 5,000 to 7,000 feet.

Hawaii’s Marine Environment: Weak surface high pressure located northeast of the state will hold light to low end moderate east to southeast breezes. A cold front associated with a large hurricane force low moving across the Central Pacific will approach the far western islands early next week. Primarily gentle to moderate easterly winds will veer more southerly ahead of this slowing front, that will eventually stall just west of Kauai Tuesday.

The front may pass across Niihau and Kauai during the middle of next week. If this does occur, expect moderate to locally fresh northerly winds in the wake of the front. A very large northwest swell will pass around the islands from Saturday through Monday. This will increase seas to Small Craft Advisory heights early next week.

A moderate size, long period northwest swell that peaked has lifted surf to High Surf Advisory (HSA) heights along the north and west-facing shores of Niihau, Kauai, Oahu and Molokai and the north-facing shores of Maui. A quick hitting reinforcing northwest swell will arrive, that will help maintain HSA level surf through this morning. North and west-facing shore surf should significantly drop this afternoon and evening.

The hurricane force Central Pacific low currently located northwest of Kauai is generating a large fetch of seas. This fetch is being aimed straight down the northwest great circle route toward the islands. The resultant very large northwest swell will produce XL size surf along north and west-facing small island shores Saturday night through Monday morning.

Long period forerunners will begin arriving Saturday afternoon, then surf will quickly ramp up Saturday evening. The peak of this event is forecast to be from late Saturday night through Sunday morning. There is a high potential for giant size surf along the north-facing shores of the smaller islands Saturday night into Sunday. A High Surf Warning for these shores will likely be in effect from Saturday night into Monday.

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

Interesting: ‘Almost Half of the Beaches Will Disappear by the End of the Century,’ Warns Researcher

Beaches around the world are undergoing a process known as “coastal squeeze” due to a combination of rising sea levels caused by climate change and urbanization in coastal areas. This phenomenon not only profoundly affects the biodiversity living on the sand, but it also harms activities such as fishing and tourism. Additionally, it makes coastal cities more susceptible to the advance of the sea.

The warning was issued during the FAPESP Day Uruguay symposium, which began on November 13 in Montevideo, by Uruguayan marine scientist Omar Defeo, a professor at Uruguay’s University of the Republic (UdelaR).

“Almost half of the beaches will disappear by the end of the century. We in Uruguay, Brazil, and Argentina share these resources. Therefore, we must work in partnership with Brazilian scientists to manage and conserve coastal ecosystems,” Defeo said in his presentation.
