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 Tuesday 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%

 

>>> Highest Temperature Tuesday, June 30, 2026 – 106 at Rio Grande Village, CA
>>> Lowest Temperature Wednesday, July 1, 2026 – 23 degrees near Kirk, OR

 

Hawaii’s Weather Highlights…as of Wednesday morning: A ridge to the north of the islands will maintain moderate to locally breezy trade winds into the weekend. Limited clouds and showers will be focused along windward and mountain areas this morning. A drier airmass is moving in from the east and is expected to further limit shower activity into the weekend. Look for muggier conditions to exist over the islands today.

Weather Commentary…as of Wednesday morning: Weather maps show a 1036 millibar high pressure system remains in place far north-northeast of the islands, with an associated ridge extending into the area north of Hawaii. A weak trough moving through the islands will continue to move to the west and dissipate over the next day or two.

The high is expected to sink southward slowly over the next couple of days, as it slowly weakens. The result will be little change in our trade winds speeds. Generally moderate trades are expected with some locally breezy conditions.

Satellite derived precipitable water values show a drier airmass will be moving into the islands later today, and lingering into the weekend. Expect some more typical trade winds showers this morning, and then as we head into tonight, a decrease in shower activity. Dew points have been in the low 70’s in many locations the last couple of days, making it feel muggier than normal. The models show another day of these same dew points, which will slowly drop back into the 60’s starting late tonight/early tomorrow…making for more comfortable conditions.

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 morning: Surface high pressure far north of the islands will maintain moderate to locally strong trade winds through this afternoon, before declining slightly to become moderate to fresh through the rest of the forecast period. The Small Craft Advisory (SCA) remains in effect through this afternoon for the windier waters and channels around Maui County and the Big Island, and may need to be extended through tonight.

A small, medium-period south swell will gradually decline through tonight. 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 small to moderate, long-period south-southwest swell will arrive, boosting surf heights to near or slightly above average.

Surf along east facing shores will remain rough and choppy and may increase today, as trade winds briefly strengthen. 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.
