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.

There’s still some heavy rainfall, although most of it is located just southwest of Kauai, which is noted by the yellow and red colors in the animated radar image below:

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

 

>>> Highest Temperature Monday, January 5, 2026 – 88 near Hidalgo, TX
>>> Lowest Temperature Tuesday, January 6, 2026 – minus 8 near Limestone, ME

 

Hawaii’s Broad Brush Weather Overview: An upper-level low and associated surface trough remain west of the islands, and will move southwestward further away from the state in the next day or so. As the low meanders away, it will begin to weaken, greatly decreasing thunderstorms and heavy rain for the Hawaiian Islands. Light winds will develop during the second half of the week allowing for sea breezes to develop, limiting only light shower activity at times.

Hawaii’s Weather Details: An upper-level low and associated surface trough west of the islands will slowly meander southwestward over the next day or so, weakening as it does, greatly decreasing thunderstorms and heavy rainfall for the Hawaiian Islands. Because of this, the Flood Watch across the state has been cancelled. Shortly thereafter, upper-level ridging will arrive in its wake by the latter half of the week, returning some sense of stability to the islands, and maintaining slightly cooler and drier conditions through the weekend.

Additionally, the the Winter Storm Warning for the Big Island Summits downgraded to a Winter Weather Advisory, persisting through midnight Wednesday as snow trends have fallen below warning criteria. The Wind Advisory for the Summits has also expired, as the latest observations have fallen below thresholds as well.

Furthermore, the wind regime throughout the weekend will trend lighter across the state, shifting to a more land-sea breeze pattern. In such a pattern, island heating will develop sea breezes each day, and overnight cooling will drive down sloping land breezes each night. During the day, sea breezes will enhance leeward and interior region shower activity, while land breezes overnight will clear the night skies and limit shower activity.

Long range model guidance for early next week, supports a weak upper-level trough escorting a surface frontal boundary through much of the state. Given how far out this event is, confidence is low. However, if this were to occur, it would bring periods of enhanced shower activity, with total precipitable water (PW) upwards of two standard deviations above average. Further analysis will be needed closer to date to detail the events more clearly.

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.
