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 Wednesday comments:  I’m at home here in upper Kula, Maui, Hawaii

510am, it’s mostly clear here in upper Kula with calm winds, and a low temperature at my place of 56.5 degrees…with the relative humidity 85%

442pm, partly sunny, although there’s quite a few clouds over along the windward side of east Maui…looks like they could be dropping some showers in places too.

 

>>> Highest Temperature Wednesday, July 1, 2026 – 108 at Stovepipe Wells, CA
>>> Lowest Temperature Wednesday, July 1, 2026 – 23 degrees near Kirk, OR

 

Hawaii’s Weather Highlights…as of Wednesday evening: A ridge to the north of the islands will weaken slightly through the latter half of the week, allowing trade winds to diminish briefly to moderate levels Thursday night into Friday, before gradually restrengthening back to locally breezy 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 Wednesday evening: High pressure remains far north-northeast of the islands, with an associated ridge to our north. This will produce moderate easterly trade winds, which should be locally breezy through Thursday, before a slight weakening of the ridge induces a slight reduction in trades Thursday night into Friday. Then, the high is expected to sink southward slowly this weekend, which will allow trade winds to gradually restrengthen.

A drier airmass moving into the islands, as indicated in satellite derived precipitable water, will linger into the weekend. Expect a return to drier conditions, with dew points already beginning to drop below 70 degrees at some locations, and less coverage of rain showers. Otherwise, the typical trade wind showers will focus along the windward and mountain areas, which will be most widespread at night and in the early morning hours.

Looking into next week, the remnant low of Tropical Storm Douglas in the Eastern Pacific is forecast to track to the northeast of the islands. At this point, impacts appear limited, with an increase of rain showers possible some time mid to late next week with trailing moisture.

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 Map / Looping Surface Precipitation…through the next 8-days / Vog Map

 

Marine Conditions…as of Wednesday evening: Surface high pressure far north of the islands will maintain moderate to locally strong trade winds through Thursday, before declining slightly to become moderate to fresh through the rest of the forecast period. The Small Craft Advisory (SCA) is in effect through Thursday afternoon, for the windier waters and channels around Maui County and the Big Island.

A small, medium-period south swell will linger through Thursday 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 potentially Sunday into Monday.

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

Interesting:  New ‘Prescription’ to Address Environmental Crisis

A new “prescription for the planet” aims to address the deepening environmental crisis.

An international team of researchers set out to understand why climate change, biodiversity loss and pollution continue to worsen despite increased green policies and funding.

They conclude that the problem isn’t just about the number of commitments and funding levels – but also the current “strategic direction”.

Their prescription gives policymakers and financial decision-makers a straightforward hierarchy of priorities – with reducing extraction and consumption top of the list.
