Hawaii’s Mountains – Here’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii. Here’s the webcam for the (~10,023 feet high) Haleakala Crater on Maui (out of operation). 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 Monday comments:  I’m at home here in upper Kula, Maui, Hawaii

521am, it’s mostly clear here in upper Kula with calm winds, and a low temperature at my place of 51 degrees…with the relative humidity 79%

415pm, I played pickleball again this morning, and as always, it was so much fun! This activity that I do typically 4-days a week is my only social outlet these days, and fortunately I thrive on the physicality as well.

6pm, sunny in most areas here on Maui, although the windward sides are partly to mostly cloudy it appears, with some showers falling over there locally.

850pm, clear to partly cloudy here in upper Kula, although it’s still quite cloudy along the windward sides, with radar showing passing showers falling.

 

>>> Highest Temperature Monday, July 6, 2026 – 115 near Topock, AZ
>>> Lowest Temperature Monday, July 6, 2026 – 32 degrees near Bynum, MT

 

Hawaii’s Weather Highlights…as of Monday evening: High pressure drives breezy trades over the next several days. Expect off and on showers focused windward and mountain areas. An increase in shower coverage is anticipated Thursday night into the weekend, particularly overnight and during the mornings.

Short Term Update: Breezy over many areas tonight, with the windiest spots being downslope in the lee of Mauna Kea through the Hamakua and Kona regions of Big Island, the southeastern West Maui range off Maalaea Bay, Kalaupapa on Molokai, as well as leeward downslope of higher Oahu terrain, where winds have remained sustained at 25 mph gusting to 35 to 40 mph.

Light, periodic showers will occur across many windward locations, with the more frequent shower activity currently focused over east Maui and windward east Oahu. The short term rainfall forecast has the highest precipitation activity centered on the windward upslope upper terrain of both Maui and Big Island through early Wednesday morning.

Weather Commentary…as of Monday evening: Upper air pattern just north of Hawaii remains stagnant, with upper high pressure ridging flanked on either side by low pressure systems. Governing high pressure changes little in position or intensity for the remainder of the week, leaving the islands in a rather typical breezy trade wind pattern.

Medium range guidance is in strong agreement that increased moisture will become entrained in these prevailing trades,  leading to an increase in shower coverage and intensity of showers Thursday night into the weekend, as the inversion weakens and lifts to around 12,000 feet. A noteworthy increase in humidity at the surface also occurs during this time. The increased mugginess will be somewhat offset by continued breezy trades.

Marine Conditions…as of Monday evening: A strong high pressure ridge centered north of the state will help to drive fresh to strong trades across all local waters through Tuesday afternoon. Winds will ease slightly to fresh to locally strong by mid-week and beyond. A Small Craft Advisory remains in effect for all waters through Tuesday afternoon.

A moderate, long period, south-southwest (180-190 degrees) swell will continue to generate surf along south facing shores just below advisory levels. This swell will slowly fade Tuesday through the remainder of the week. Expect small surf for south facing shores leading into the weekend. Another moderate, long period south-southwest swell (210-220 degrees) may fill in Sunday, but due to the direction of the source could be more inconsistent than this current swell.

Surf along east facing shores will remain rough and choppy through the week, as fresh to strong trades hold. Expect flat to tiny surf along north facing shores.

Interesting:  Antarctic Sea Ice Packed With Climate Cooling Compounds

Antarctica’s frozen seas are churning out chemicals that could help cool the planet – according to new research from the University of East Anglia.

A new study reveals that sea ice in the Southern Ocean contains dramatically higher levels of a key compound linked to climate regulation than the surrounding waters.

But as climate change continues to shrink and thin polar ice, the balance of this chemical factory could change – with unknown consequences.

In collaboration with the University of Pretoria and Stellenbosch University in South Africa, scientists studied a chemical called dimethylsulfoniopropionate (DMSP) – which plays a crucial role in cooling the planet.
