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 Sunday comments:  I’m home here in upper Kula, Maui, Hawaii.

It’s clear to partly cloudy here in Maui County this morning….with some cloudy areas.  The low temperature at my place was 54 degrees.

Weather Wit of the day:  Ground – The only thing guaranteed to stop the falling rain

>>> Highest Temperature Saturday, July 5, 2025 – 113 at Stovepipe Wells, California
>>> Lowest Temperature Sunday, July 6, 2025 – 26 near Mackay, Idaho

 

Hawaii’s Broad Brush Weather Overview:  A strong high pressure ridge parked north of Hawaii will produce a stable and breezy to windy trade wind weather through Monday. Wind speeds will decrease slightly on Tuesday into the moderate to breezy range. Brief passing showers will favor windward and mountain slopes, with late afternoon to evening showers along the Kona slopes of the Big Island, other leeward areas will be mostly dry.

Hawaii’s Weather Details:  Satellite pictures show fairly stable stratocumulus clouds riding into the windward mountain slopes of each island on the easterly trade winds. Upper air balloon soundings over the past 24 hours at Lihue and Hilo are observing temperature inversion heights in the 6,000 to 7,000 foot range. This means that brief passing showers, as shown on local doppler radar will continue mainly over windward and mountain areas.

The strong ridge north of the state will build in over the islands today, increasing trade wind speeds into low level Wind Advisory thresholds for windier areas of Maui and Hawaii Counties. A Wind Advisory was issued this morning for 20 to 30 mph wind speeds with gusts up to 50 mph at times lasting through Monday afternoon.

Fairly dry conditions with lower humidity levels coupled with these stronger winds will produce elevated fire weather conditions over leeward areas during the late morning to afternoon hours. Wind speeds will decrease slightly into the moderate to breezy range from Tuesday onward.

Weather conditions into Wednesday continue to show a dry and breezy summer time conditions through much of the week. In the medium to long range weather outlook, models continue to show a slight increase in low level moisture and possibly a modest increase in shower activity from Wednesday night onward.

Fire weather: Breezy, gusty, and rather dry conditions will continue for the next few days. Minimum relative humidity at lower leeward elevations will likely fall at or below 45 percent each afternoon. Temperature inversion heights will drop as low as 5,000 feet. This will result in near critical fire weather conditions over dry leeward areas at times.

Hawaii’s Marine Environment:  High pressure will remain far north of area for the next several days, which will support fresh to strong trade winds across the islands. The Small Craft Advisory remains in effect for all Hawaiian coastal waters until 6pm Monday, but this will likely need to be extended for some zones as gusty trades persist into early in the new week. The aforementioned surface high will move eastward and weaken slightly during the latter half of the week, but winds are likely to remain locally breezy in the typical windier channels and waters throughout much of the next 7-days.

Surf along all shores will remain mostly unchanged, though south shore surf is expected to slowly decline as a south swell fades over the next several days. The next small, medium- to long-period south swell is expected to arrive late Tuesday through Wednesday. This swell may boost south-facing shore surf heights to near summertime averages as it peaks on Wednesday. It will then decline through the rest of the week.

Surf along east-facing shores will be rough and choppy in response to the gusty easterly trade winds.

Invest 96E

>>> An area of low pressure has become a little better defined about 400 miles southwest of the coast of southwestern Mexico. However, the associated showers and thunderstorms remain disorganized. This system could still become a short-lived tropical depression before it moves into unfavorable environmental conditions on Monday.

* Formation chance through 48 hours…medium…40 percent
* Formation chance through 7 days…medium…40 percent

South of Southwestern Mexico:

>>> An area of low pressure could form several hundred miles offshore of southwestern Mexico late this week. Some gradual development of this system is possible thereafter while it moves generally west-northwestward well off the coast of Mexico.

* Formation chance through 7 days…low…20 percent

Interesting:  Thunderstorms Are a Major Driver of Tree Death in Tropical Forests

Cary-led paper reveals an underestimated and growing threat to tropical forests and the carbon they store.

Trees in tropical forests are dying at an increased rate, with consequences for biodiversity, carbon storage, and the global climate. While deforestation is the primary cause of forest loss, intact forests are also experiencing a rise in tree death. Drought, higher temperatures, and fires have been the leading suspects, but a new paper led by Evan Gora, a forest ecologist at Cary Institute of Ecosystem Studies, identifies an underappreciated threat: thunderstorms, which are becoming more frequent with climate change.

Not to be confused with hurricanes or cyclones, these convective storms tend to be short-lived but powerful, with tree-toppling winds and lightning. In a perspective paper in Ecology Letters, Gora and colleagues lay out the case for why such storms could be a major driving force behind the rising death toll of tropical trees. As they become more common in the warming tropics, thunderstorms are a growing threat to trees and the carbon they store.

“Tropical forests have massive effects on global climate. They’re like the lungs of the Earth, and we’re seeing trees in them dying at higher rates than in the past, and the composition of forests is changing, too,” said Gora. “That could be really problematic for the future of not just tropical forests, but for the planet.”
