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 Tuesday comments:  I’m here at home in upper Kula, Maui

It’s partly cloudy here in Maui County early this morning, with a low temperature of 54.5 degrees at my place, with the relative humidity 76 percent.

130pm, it’s wonderful summer day right here in the middle of winter!

526pm, I was just going to take my 3rd walk of the day, but looking down into the central valley, from here in upper Kula…I see that it’s way too voggy to be breathing deeply!

 

Weather Wit of the day: Winter Forecast – “mostly cloudy with patches of flu”

 

>>> Highest Temperature Tuesday, January 6, 2026 – 90 near Hidalgo, TX
>>> Lowest Temperature Tuesday, January 6, 2026 – minus 8 near Limestone, ME

 

Hawaii’s Broad Brush Weather Overview: Showers will continue to decrease and breezy easterly trade winds diminish tonight and Wednesday, as low pressure west of Hawaii fills and high pressure to the northeast weakens. A deep ridge settling over the islands on Thursday, will lead to light winds and stable conditions with light interior showers. A dissipating cold front will bring an increase in showers to Kauai and Oahu Friday into the weekend, followed by another cold front early next week.

Hawaii’s Weather Details: A gradual drying trend is underway, as breezy easterly trade winds continue to focus showers over windward and southeast slopes. An upper level low is filling several hundred miles southwest of Hawaii as it drifts away, limiting instability locally. Its associated surface trough, combined with strong high pressure far northeast of the area, continues to produce breezy easterly trade winds over the islands, but the broad zone of convergence that is producing the heaviest showers has shifted west of Hawaii.

As a result, rain rates have dropped considerably over the state, and the wettest windward slopes on Kauai and Big Island have measured generally between a third to an inch of rain during the past six hours. Most leeward areas have been dry, but as the high clouds thinned, interior Big Island has experience a few heavy showers over the interior and South Kona slopes due to daytime heating. Expect all areas to continue to experience a gradual drying trend overnight as trades begin to decline.

Trades will continue to ease on Wednesday and will shift out of slightly south of due east, as the high to the northeast drifts away. Drier and increasingly stable mid level air pushing in from the east, will lead to a decline in rainfall over windward and southeast slopes. Sea breezes will be more extensive across leeward areas, but aside from the Big Island, showers will be isolated.

A high pressure ridge at the surface and aloft will move over the island chain on Thursday. Light and variable winds will give way to sea breezes in the afternoon, triggering interior clouds and a few showers. The atmosphere will be stable, keeping rainfall accumulation minimal.

A shallow and weakening cold front will advance to Kauai on Friday, then stall and slowly dissipate over the western end of the island chain during the weekend. As shower chances increase for Kauai on Friday and possibly as far south as Oahu on Saturday, the rest of the state will experience rather dry conditions dominated by light land and sea breezes.

Chances for showers will decrease on Sunday as the remnant moisture band dissipates, and lifts northward ahead of another advancing cold front. This potentially stronger front may move down the island chain early next week, though uncertainty regarding this feature remains high at this time.

Hawaii’s Marine Environment: A trough west of Hawaii will shift westward allowing a ridge to build north of the region. The threat of heavy showers and thunderstorms will diminish. Strong to near gale force east to southeast winds will gradually ease, becoming gentle to locally fresh speeds Wednesday. A front approaching the state from the northwest will further ease wind speeds to light to moderate Thursday.

The frontal boundary will weaken as it enters to coastal waters Friday and dissipate near the central islands by Saturday. Brief moderate to fresh northerly winds will fill in behind the front, but become light to gentle speeds Saturday as another stronger front approaches the state from the northwest Sunday, veering winds more southerly and gradually becoming more moderate before pushing south over the island chain next week.

A Small Craft Advisory (SCA) for both winds and seas remains in effect for the all coastal waters through early Wednesday morning. Wind and sea conditions will drop below advisory thresholds Wednesday through the remainder of the week, as the trough moves further west and away from the islands.

A moderate, medium period, north-northeast (040-060 degree) swell will veer more easterly and decline. A small, long period, northwest (310 degree) swell will build late tonight, peak Wednesday and slowly decline through Friday. Forerunners for the next significant large, long period north-northwest swell (330 degree) is expected to arrive Friday night and peak Saturday. This swell will likely produce warning level surf along exposed north and west facing shores. Seas will build above SCA criteria during this time for most waters. Another, large to extra large, north-northwest swell may fill in early next week, with surf heights peaking well into warning levels.

A High Surf Advisory remains in effect for exposed east facing shores, due to the combination of the northeast swell mentioned above and rough easterly swell generated by the local and upstream easterly winds. Surf will drop below advisory levels Wednesday.

The Coastal Flood Statement has been canceled. Most tide gauges show peak water levels have dropped near to below minor flooding levels during peak tides, and will continue to trend below minor flooding levels with the peak high tide.

Interesting:  Study Reveals Third hand Smoke as Hidden Indoor Air Pollutants

A new study published in the scientific journal Building and Environment reveals a persistent and evolving threat to indoor air quality known as “third hand smoke.”

While the risks of secondhand smoke are well understood, this study, led by researchers from the Institute of Atmospheric Physics (IAP) at the Chinese Academy of Sciences, provides the first real-time analysis of how third hand smoke lingers and chemically transforms in our homes long after active smoking has ceased.

Third hand smoke is the toxic residue from tobacco smoke that adheres to surfaces such as walls, furniture, carpets and curtains. Unlike secondhand smoke, which is inhaled directly from the air, this contamination can embed itself in indoor environments.

The study demonstrates that it is not an inert stain but a dynamic source of pollution, continuously re-emitting particles and gases back into the air and undergoing chemical changes over time.
