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

It’s mostly clear here in Maui County this morning…with a few clouds locally.  The low temperature at my place was 52 degrees.

Partly cloudy in general, although with more clouds over and around the mountains. I just got back from playing Pickleball in Haiku, which was very fun!

Weather Wit of the day:  Dark Cloud – A pessi-mist

>>> Highest Temperature Monday, June 30, 2025 – 118 at Stovepipe Wells, California
>>> Lowest Temperature Tuesday, July 1, 2025 – 31 at Peter Sinks, Utah

 

Hawaii’s Broad Brush Weather Overview:  Light trades prevail across the Hawaiian islands as a surface trough persists just to the north. As this trough exits the vicinity of the islands by mid-week, high pressure will build to the north in its wake, backing trades to a more easterly component and increasing to a more moderate to breezy range through the remainder of the week. Expect drier conditions during this time as well. By the weekend and into next week, trades could become moderate to strong as high pressure is forecast to build further.

Hawaii’s Weather Details: Light trades prevail across the state in response to a surface trough that has persisted north of the islands, that has deteriorated the pressure gradient. Some localized sea breezes may occur throughout the day again, triggering possible leeward and interior area showers, but will be far less energized in comparison to earlier this week, as the surface trough weakens and exits the vicinity to the west. Thereafter, the surface high well north of the island chain will rebuild, allowing trades to gradually back out of the east, and strengthen slightly to moderate to localized breezy conditions.

As the week progresses, expect drier conditions to ensue as drier air is forecast to move into the vicinity of the islands. Despite this, typical trade showers can be expected across windward and mountain areas, but at modest levels given the lack of available moisture. This trend will continue through the weekend and into next week.

Meanwhile, latest model guidance remains in pretty good agreement that trades will strengthen further, becoming breezy to localized strong at times into early next week. The conjunction of drier conditions with these stronger trades could elevate fire weather concerns. While this is still several days out, and confidence remains low at the moment, conditions should be monitored leading up to the weekend into next week.

Hawaii’s Marine Environment:  A weak high pressure ridge anchored north of the Hawaiian Islands will keep gentle to fresh easterly trade winds in the forecast through Friday. The ridge will build in north of the island chain by Saturday, increasing trade winds into the fresh to locally strong range into early next week. There are no Small Craft Advisories (SCA) currently in effect, however stronger winds forecast to arrive this weekend will likely bring a return to SCA conditions for wind over the typically windier waters around Maui and the Big Island.

A small long period south swell will hold through Wednesday. Another smaller longer period south swell then builds into the local waters from Thursday onward, keeping surf heights along south facing shores fairly steady. Surf heights along east shores matches trade wind trends, subsiding and remaining small this week, then increasing slightly this weekend. Surf heights along west facing shores will see some south swell wrap, with north facing shores remaining nearly flat.

 



World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  There are no active tropical cyclones

Caribbean Sea:  There are no active tropical cyclone

Gulf of America:  There are no active tropical cyclone

Near the southeastern U.S.  

>>> An area of low pressure could develop near the southeast U.S. Atlantic or Gulf coasts over the weekend along a weakening front. Although significant development is not anticipated, a tropical or subtropical depression could form in this region over the weekend or early next week while the system drifts and moves little. Regardless of development, heavy rainfall is possible across portions of the southeast U.S., particularly across the west-central Florida coast.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…medium…40 percent

 

Northeastern Pacific:   

Tropical Cyclone 06E (Flossie)…is located about 200 west-southwest of Manzanillo, Mexico

FLOSSIE BRINGING GUSTY WINDS AND RAIN TO THE SOUTHWESTERN COAST OF MEXICO

According to the NHC advisory number 11A

Flossie is moving toward the northwest near 7 mph. A west-northwest to northwest motion is anticipated during the next few days. Maximum sustained winds are near 110 mph with higher gusts. Some additional strengthening is possible tonight. By Wednesday, steady to rapid weakening is expected. Hurricane-force winds extend outward up to 25 miles from the center and tropical-storm-force winds extend outward up to 90 miles.

South of Southwestern Mexico:

>>> An area of low pressure is forecast to develop several hundred miles offshore of southwestern Mexico late this week. Environmental conditions appear conducive for some gradual development of this system thereafter, and a tropical depression could form over the weekend while it moves generally west-northwestward.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…medium…40 percent

Interesting:  Where There’s Fire, There’s Smoke

New app estimates health impacts of breathing smoke from wildfires.

Earlier this year, wildfires in southern California killed 30 people, destroyed more than 18,000 homes and burned more than 57,000 acres. The fires were a stark reminders of the threat of worsening climate change, and the increased likelihood of future devastating fires. With these fires comes smoke, which has long-term health effects for the people exposed to it – whether they are close to the source, or many miles away.

A Harvard atmospheric modeling team has created an online platform that could help communities identify areas in need of controlled burns or other fire management strategies, with the goal of preventing future uncontrolled fires and, more specifically, reducing smoke exposures.

The research is published in Environmental Science & Technology and is led by Loretta Mickley, senior research fellow in chemistry-climate interactions at the John A. Paulson School of Engineering and Applied Sciences (SEAS) and leader of the Atmospheric Chemistry Modeling Group. Two alumni from Mickley’s group co-led the effort: Tianjia (Tina) Liu, now an assistant professor at University of British Columbia, and Makoto Kelp, now a postdoctoral fellow at Stanford University.
