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. 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 at home here in upper Kula, Maui, Hawaii

5am, it’s mostly clear here in upper Kula with calm winds, and a low temperature at my place of 53.5 degrees…with the relative humidity 81%

101pm, another sunny to partly sunny day, with some of the usual cloudy areas over and around the mountains. I played pickleball in Makawao again today, and had lots of fun. BTW, these are not easy going games, they are rousing to da max, at least in my way looking at it…playing it.

 

>>> Highest Temperature Thursday, July 2, 2026 – 107 at Stovepipe Wells, CA
>>> Lowest Temperature Thursday, July 2, 2026 – 23 degrees at Peter Sinks, UT

 

Hawaii’s Weather Highlights…as of Thursday afternoon: A ridge to the north of the islands will sink south and gradually strengthen, allowing moderate trade winds to build back to locally breezy levels over the weekend. Clouds and showers will remain focused mainly along windward and mountain areas through the middle of next week. A drier airmass moving in from the east is expected to induce a drying trend that limits shower activity into the weekend.

Weather Commentary…as of Thursday afternoon: High pressure will remain far to north of the islands through the weekend. Winds will remain at moderate levels through tonight and Thursday, but then strengthen a bit this weekend to moderate to locally breezy levels, as ridging sinks southward somewhat.

Despite a generally drier airmass moving into the islands, satellite imagery indicates a band of enhanced rain showers moving in over Kauai and Oahu. These showers have produced up to a tenth of an inch of rainfall over the past 6 hours, but have remained over windward and mountain areas. Over the next several days, conditions will be similar, with showers focused over the windward and mountain areas, heaviest and most widespread during the overnight and early morning hours. No significant rainfall totals are expected over the next couple of days.

Otherwise, winds will gradually increase through the weekend, back to moderate to locally breezy levels by Sunday, and remain so through the first half of next week. Additionally, expect a continued gradual drying trend, with afternoon relative humidities reaching the mid 40’s for leeward areas.

Tropical Storm Douglas in the east Pacific is expected to weaken to a remnant low Friday. Leftover moisture from this system will likely be carried into the islands on the trade wind flow, during the middle to latter half of next week. This could increase shower activity, mainly to the windward and mountain locations.

Marine Conditions…as of Thursday afternoon: A surface high pressure far north of the islands will maintain moderate to locally strong trade winds. A Small Craft Advisory (SCA) for the typical windy waters and channels around Maui County and the Big Island has been extended into the weekend. The SCA will likely remain in place through the forecast period, as the high remains nearly stationary, with minor fluctuations in strength.

Forerunners of a small, long period south swell are filling in will peak tonight into Friday. This swell will help maintain near to just below summertime average surf along south facing shores into the weekend. A moderate, long period south-southwest swell will fill in Saturday afternoon and evening, boosting surf heights to near High Surf Advisory levels Sunday and Monday. This swell will slowly fade Tuesday through the middle of next week.

Surf along east facing shores will remain rough and choppy through the forecast period, as moderate to locally strong trades hold. Surf along north facing shores will remain tiny into Friday, with a minor uptick Friday afternoon into the holiday weekend, as a small, medium period northwest swell arrives. Tiny to near flat conditions for north facing shores will return next week.

Interesting:  Decline in Plankton Across North East Atlantic Sends Stark Warning for Ocean Health

Microscopic plankton are among the most important organisms on Earth. Phytoplankton produce around half of the oxygen we breathe, while plankton as a whole underpin marine food webs, support fisheries, help regulate carbon, and sustain life across the ocean.

However, a new study – led by researchers at the University of Plymouth – has used more than six decades of data to show that plankton abundance is declining across vast swathes of the North East Atlantic – a region covering the Atlantic Ocean from Portugal to Norway, and the entirety of the North Sea.

The research used 23 plankton datasets from 13 research institutions, alongside satellite data, to generate the first ever quantitative and integrative assessment of whether the pelagic habitats of western Europe are in Good Environmental Status, as defined by the EU and UK Marine Strategy Framework Directive.
