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

It’s mostly clear here in Maui County early this morning.  The low temperature at my place was 53 degrees.

Weather Wit of the day:  Humidity – What heat uses for an Alibi

1205pm, I went up the mountain to skateboard, and got four good runs in, although had to pull over several times, due to the cars going up and down the mountain. Nonetheless, it’s always nice to be up on the slopes of the Haleakala Crater…and I didn’t fall!

>>> Highest Temperature Thursday, August 14, 2025 – 116 near Tecopa, California
>>> Lowest Temperature Friday, August 15, 2025 – 31 near Bynum, Montanta

 

Hawaii’s Broad Brush Weather Overview:  High pressure will rebuild across the area today through early Sunday, bringing moderate to locally breezy trades across the islands. By Sunday, another low-level trough, remnants of former Tropical Cyclone Ivo) propagates westward into the vicinity of the Hawaiian Islands. This will result in an increase of cloud coverage and shower activity, predominately for windward and mountain areas, persisting through Monday. Thereafter, expect stable and drier conditions to return through the remainder of the week.

Hawaii’s Weather Details: Latest satellite imagery continues to show a low-level trough just north of the islands, responsible for the current hybrid sea breeze/light trades pattern. Model guidance continues to showcase the trough meandering westward, distributing increased clouds and shower activity across much of the state, predominately along windward and mountain areas. Local radar supports pockets of isolated showers moving east to west across the islands, though with minimal impacts.

Moderate to locally breezy trades return to the islands as a surface ridge builds just to the north. Latest satellite guidance depicts drier air will begin to stream from the east, as a broad upper- level ridge moves back over the state. Temperature inversions will lower as a result, increasing cloud coverage and shower activity, predominately over the windward and mountain areas through much of the weekend.

Toward the latter part of the weekend, another trough from the remnants of former Tropical Cyclone Ivo will make its way over the islands. Humidity levels steadily increase across the state as the trough moves closes to the vicinity of the islands, beginning Sunday afternoon and lasting through midday Monday. Inversion heights will lift to around 8,000 to 9.000 feet enhancing clouds and showers in a moderate trade wind weather pattern.

However, its important to note that confidence on the track of this trough remains low at the moment, as remnant tropical systems tend to be smaller in size and can shift off the current track as time passes. Should the system track further north than the current forecast, fewer clouds and showers will reach the Hawaiian Islands. Therefore, further updates will become necessary to increase confidence.

As the trough exits the region to the west, high pressure quickly rebuilds again commencing Tuesday. During this time, expect more stable and drier conditions, with moderate to locally breezy trades and a more typical summer-like trade wind weather pattern through the remainder of the forecast period.

Fire weather:  Weather conditions should remain below critical fire weather thresholds into early next week. A low-level trough north of the islands will continue to propagate westward, with another low-level disturbance associated with the remnants of former Tropical Cyclone Ivo in its wake. Expect increased humidity levels and shower activity Sunday through Monday. Thereafter, lower humidity levels and more stable conditions will return Tuesday, as high pressure rebuilds over the islands, persisting through the remainder of the week.

Hawaii’s Marine Environment:  Winds will be on the increase, and Small Craft Advisory (SCA) level winds could trickle into these coastal waters by the end of the day.

A surface trough north of the islands will continue to trek to the west over the next couple of days. In its wake, surface ridging will allow trade winds to gradually strengthen through the weekend, leading to the SCA conditions mentioned above.

Surf along south facing shores will see a slight bump and likely another small bump Saturday, as a series of small long period southerly swells arrive. Surf is expected to hold through early next week.

A small, medium period northeast swell will keep surf along east facing shores elevated through the weekend. As this swell declines, the short period energy will fill in as trade winds increase into the weekend. North facing shores will remain flat to tiny through the forecast period, except for areas that may be exposed to the small northeast swell.

 



World-wide Tropical Cyclone Activity

 

Atlantic Ocean:   

Tropical Cyclone Erin…is 365 east of the Northern Leeward Islands

ERIN MOVING WEST-NORTHWESTWARD AND FORECAST TO RAPIDLY STRENGTHEN…EXPECTED TO PASS NEAR OR NORTH OF THE LEEWARD ISLANDS ON SATURDAY

According to the NHC advisory number 18

Erin is moving toward the west-northwest near 17 mph. This motion is expected to continue through the weekend with some decrease in forward speed. On the forecast track, the center of Erin is likely to move just north of the northern Leeward Islands, the Virgin Islands, and Puerto Rico over the weekend. Maximum sustained winds are near 75 mph with higher gusts. Steady to rapid strengthening is expected during the next two to three days, and Erin is forecast to become a major hurricane during the weekend. NOAA and Air Force Reserve Hurricane Hunter aircraft are scheduled to investigate Erin this evening. Hurricane-force winds extend outward up to 25 miles from the center and tropical-storm-force winds extend outward up to 115 miles mainly to the north of the center.

>>> Shower and thunderstorm activity has persisted in association with a disturbance located about 75 miles off the coast of northeastern Mexico or southern Texas coastline. The system could become a short-lived tropical depression before it moves inland this afternoon or evening. Regardless of development, locally heavy rainfall is possible along portions of northeastern Mexico and southern Texas over the next couple of days, and interests there should monitor the progress of this system. Another Air Force Reserve Hurricane Hunter aircraft is scheduled to investigate the system later this morning.

Interesting:  Surprisingly Diverse Innovations Led to Dramatically Cheaper Solar Panels

New research can identify opportunities to drive down the cost of renewable energy systems, batteries, and many other technologies.

The cost of solar panels has dropped by more than 99 percent since the 1970s, enabling widespread adoption of photovoltaic systems that convert sunlight into electricity.

A new MIT study drills down on specific innovations that enabled such dramatic cost reductions, revealing that technical advances across a web of diverse research efforts and industries played a pivotal role.

The findings could help renewable energy companies make more effective R&D investment decisions and aid policymakers in identifying areas to prioritize to spur growth in manufacturing and deployment.
