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.

~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Wednesday comments:  I’m here in Bend, Oregon with my friend Bob Earle…although, Bob and I will be driving the 9 hours from here in Bend down to our friend Linda’s place in Marin County today. Thus, I won’t be able to update the weather information until I set my computer up late this afternoon or even early this evening.

It’s mostly cloudy here in Bend early this morning with sprinkles. The low temperature was 34.5 degrees.

Weather Wit of the day: Rainy October – Indian Bummer

>>> Highest Temperature Tuesday, November 4, 2025 – 95 near Tecopa, California
>>> Lowest Temperature Wednesday, November 5, 2025 – 12 near Angel Fire, New Mexico

 

Hawaii’s Broad Brush Weather Overview: Moderate to locally breezy trades will persist through Thursday, focusing showers over windward and mountain areas, while high clouds continue to stream overhead. Winds will weaken Thursday into Friday as a cold front approaches from the northwest, allowing for sea breeze development and limited shower activity over leeward and interior areas.

Confidence remains lower for the weekend forecast, but the cold front is expected to bring breezy to windy northeasterly winds and increased showers to at least the western end of the state, with moisture potentially spreading farther east into early next week.

Hawaii’s Weather Details: Radar and satellite imagery show high clouds streaming northeast over the islands, with low clouds and isolated showers riding in on the moderate trades to windward and mountain areas. These upper-level icy clouds will continue drifting overhead for the next couple of days, which will mute our sunshine, and perhaps helping to moderate high temperatures a bit, and could make for some nice sunrise and sunset colors.

As the tail-end of a cold front to the north of the state transitions into a surface trough by tonight, the high pressure to our northwest and another high pressure center building to the distant northeast will help to drive moderate to locally breezy trade winds across our area through Thursday. At the same time, a mid level ridge will build over the state, maintaining a fairly stable trade wind pattern into Thursday, focusing shallow clouds and showers mainly across windward and mountain areas. In addition, leeward areas of the Big Island will see sea breeze activity with the typical afternoon showers.

Winds begin to weaken on Thursday as the cold front approaches the region from the northwest, with lighter veered winds over the western end of the state, prompting localized sea breeze activity over Kauai and Oahu. With limited low level moisture being brought in on the weakening trades at that time, these sea breezes will likely only bring some clouds and perhaps a few isolated showers to leeward and interior areas Thursday afternoon.

The trades are expected to fully collapse by Friday, giving way to light and variable or northerly winds as the front nears Kauai. While moisture still looks to remain somewhat limited, statewide sea breeze activity will build low level clouds over leeward and interior areas, and once again will produce isolated shower activity.

Forecast confidence decreases heading into the weekend due to model differences in the position and timing of the approaching front. Confidence is higher that the front will at least reach the western islands, where breezy to windy northeasterly winds and increased showers are expected. Guidance shows some members stall the front near Kauai, others across the central islands, and a few progress it all the way down to the Big Island, hence the decreased confidence.

The weather early next week will be dependent on the evolution of the aforementioned front. It looks like most of the state will see breezy to windy northeast trades with enhanced moisture near the frontal boundary. With mid level ridging building back over the region, inversion heights will lower once again, keeping the moisture confined to lower levels and focusing clouds and showers over windward and mountain areas.

Fire weather: Winds and relative humidity values are expected to remain below critical fire weather thresholds into the weekend. The inversion will be between 6,500 to 7,500 feet today, as a mid level ridge builds overhead, further stabilizing the atmosphere and limiting vertical cloud growth.

Hawaii’s Marine Environment: A high pressure ridge north of the Hawaiian Islands will build, increasing the trade winds into the fresh to locally strong range into tonight. Winds then decrease from Thursday onward as a cold front approaches the region from the northwest. These stronger winds and higher seas will produce Small Craft Advisory (SCA) conditions for most coastal waters into Thursday. The current SCA was expanded to include windward Oahu and Kauai waters for seas, and extended in time through Thursday.

Trade winds will gradually decline from Thursday through Friday as a cold front north of the Islands moves into the area from the north. Models show this cold front weakening and stalling over the northwestern and central waters from Saturday to Sunday. Stronger northeast winds will blow across waters north of the front, with moderate easterly winds south of the frontal boundary.

A gale force low that passed far north of the state on Monday has produced a moderate to large medium period north-northwest (340-350 degree) swell that, will build into Hawaiian waters through Thursday. Surf heights along exposed north and west facing shores will exceed surf advisory thresholds into Thursday, before steady declining. A High Surf Advisory (HSA) was issued for these areas. An overlapping north-northwest swell will move into the region by Friday, helping to maintain moderate surf heights along north and west facing shores.

In the longer range forecast, a deep low pressure system is expected to develop to our north and northeast from Friday into Saturday. This low will likely generate a large north-northeast (020-030 degree) swell late this weekend, easily exceeding HSA thresholds. Due to the swell angle, heavy surges will be possible along north facing harbors such as Kahului and Hilo on Sunday.

South facing shores will remain small throughout this week. A small long-period south-southwest swell will boost south shore surf heights from Thursday into the weekend, along with a larger, out of season south swell, possible by early next week. Surf for east facing shores should be rough and choppy Thursday with the increasing trade winds and could also see a little bit of north wrap from the medium period north-northwest swell.

Peak monthly tides combined with water levels that are running higher than predicted will lead to minor flooding along the shoreline and in low-lying coastal areas. The greatest chance for coastal flooding will occur during the daily peak high tide during the early morning hours, and along north facing shores exposed to the large north-northwest swell.

Interesting:  Plastic-Munching Bacteria Found Across the Seven Seas

New enzyme motif shows how ocean microbes are evolving to digest plastic — and could help future cleanup efforts.

Deep within the world’s oceans lurk marine bacteria armed with plastic-munching enzymes, their evolution seemingly sculpted by our synthetic castaways.

A global survey of oceanic life from researchers at KAUST shows that these microbial recyclers are not only widespread, but genetically primed to feast on polyethylene terephthalate (PET), the durable polymer found in everything from soda bottles to clothing.

Their secret weapon is a telltale structural stamp on the PET hydrolase enzyme, known as PETase: the M5 motif.
