Hawaii’s MountainsHere’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.

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%

 

>>> Highest Temperature Wednesday, July 1, 2026 – 108 at Stovepipe Wells, CA
>>> Lowest Temperature Thursday, July 2, 2026 – 23 degrees at Peter Sinks, UT

 

Hawaii’s Weather Highlights…as of Thursday morning:  A ridge to the north of the islands will weaken slightly through the rest of the week, allowing trade winds to diminish briefly to moderate levels tonight into Friday, before gradually restrengthening back to locally breezy levels over the weekend. Clouds and showers will remain focused mainly along windward and mountain areas into early next week. A drier airmass moving in from the east is expected to limit shower activity into the weekend.

Weather Commentary…as of Thursday morning: High pressure far to the north of the islands will remain in place through the weekend. Winds are expected to weaken a bit tonight and Friday to moderate levels, although then strengthen a bit this weekend, to moderate to locally breezy levels.

Satellite derived precipitable water values show a drier airmass moving into the islands today, which will limit shower activity. Any clouds and showers that do get carried in on the trade wind flow, will be focused over the windward and mountain areas. No significant rainfall totals are expected over the next couple of days.

Dew points have been in the low 70’s the last couple of days, but have started to slowly lower back into the upper 60’s, which will make it a little less muggy. Expect dew points to remain in the mid to upper 60’s through the holiday weekend.

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

Here’s a near real-time Wind Profile of the Pacific Ocean – along with a Closer View of the islands / Here’s the latest Weather MapLooping Surface Precipitation…through the next 8-days / Vog Map

 

Marine Conditions…as of Thursday morning: Surface high pressure far north of the islands will maintain moderate to locally strong trade winds today before slightly declining, becoming moderate to fresh through the rest of the week. A Small Craft Advisory (SCA) is in effect through 6pm this evening for the typical windy waters and channels around Maui County and the Big Island.

A small, medium-period south swell will linger just below the summertime average. This fading swell combined with a series of small, medium- to long-period south-southwesterly swells, will deliver below-average surf along south-facing shores through Friday. Over the holiday weekend and into early next week, a moderate, long-period south-southwest swell will arrive, boosting surf heights to near High Surf Advisory levels Sunday into Monday.

Surf along east facing shores will remain rough and choppy through Friday, as trade winds remain locally strong. Surf along north facing shores will remain tiny, with a minor increase possible Friday into the holiday weekend, as a small, medium- period northwest swell arrives.

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.
