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 Thursday comments:  I’m here in Corte Madera, Marin County, California, at my friend Linda’s on a working vacation.

I spoke with a friend who works at the NWS forecast office in Honolulu, and he said that there are major software and personnel changes going on now, so expect less weather information for the time being!

Weather in some parts of the island chain are voggy, especially over parts of the Big Island and Maui County!

I played pickleball this morning here in Corte Madera, and it was one of my best sessions here in California! I’m beginning to meet some really cool folks, as I’m entering the tail-end of my month long working vacation.

It stayed cloudy and cool all day today, and more of the same is expected on Friday.

I understand that the voggy conditions remain in place or some areas of the state, including Maui County.

Weather Wit of the day:  Snowfall – Driveway robbery

 

Hawaii’s Broad Brush Weather Overview:  Mild weather conditions will continue through the weekend. Moderate to breezy southeasterly winds give way to expanding sea breezes and interior clouds with a few showers each afternoon, mainly over the smaller islands.

Hawaii’s Weather Details:  Quiet conditions prevail across the area as convection near Kauai has lifted well north. Weakly convergent southeast wind flow is bringing enhancement to interior cloud development over Oahu, where isolated to scattered showers will be possible.

This in turn sets the stage for a rather typical diurnal flare up in showers over Oahu and possibly Kauai without any expectation of widespread or heavy rain. Moderate to breezy SE flow is established area-wide.

Moderate southeast wind flow will tend to be shadowed downstream of the larger islands through the latter portion of the week, leading to locally diminished winds over the western end of the state, and introducing potential for an expansion of sea breezes during the afternoons.

This increases potential for interior clouds and a few showers during the afternoons. This will especially be the case during the latter half of the weekend, when models indicate  renewed mid-level troughing. Stability remains low throughout this time, suggesting that locally heavy showers will be possible on days when sea breeze convergence is maximized.

Hawaii’s Marine Environment:  Moderate to locally breezy southeast winds return today into the weekend, with winds further weakening early next week, followed by the potential return of trades mid-week.

An existing small, medium period northwest swell continues to fade providing little in the way of surf for north and west facing shores through Friday. A slightly larger long-period northwest swell is forecast this weekend, though surf still remains well below advisory thresholds for north and west facing shores. Ongoing small, long period south-southwest swells will slowly decline through the remainder of the week. Lack of upstream trades favors near to below average surf along east facing shores, though some chop resulting from current southeast winds may reach the waters off of east facing shores during the next few days.

Interesting: Heat and Fire Making Pollution Worse Across Much of the U.S.

By several measures, air pollution is getting worse in the U.S., a trend due in large part to more severe heat and wildfires, according to a new report.

Parts of the country that were not previously burdened by smog have seen pollution worsen in recent years as heat and sunlight transform car exhaust into ozone pollution. “Warmer temperatures driven by climate change make ozone more likely to form and harder to clean up,” according to the new report, from the American Lung Association. The group found that, from 2021 to 2023, five times as many counties saw ozone pollution worsen as saw it improve.

Wildfires were also a factor in ozone pollution, and in parts of the country led to spikes in particulate pollution. Last year, the number of days in which counties recorded “unhealthy” and “very unhealthy” levels of particulates reached their highest level in at least two decades. The report found that a growing number of Americans are facing dangerous levels of particulate pollution, a trend “that not only is continuing but worsening as a consequence of climate change.”
