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 Aloha Friday 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 Thursday, July 2, 2026 – 107 at Stovepipe Wells, CA
>>> Lowest Temperature Friday, July 3, 2026 – 24 degrees at Peter Sinks, UT

 

Hawaii’s Weather Highlights…as of Friday morning: Moderate to breezy trade winds will prevail through the week as high pressure holds far north of the islands. Stable conditions will focus limited showers over windward and mountain areas.

Weather Commentary…as of Friday morning: A high pressure system is centered roughly 1300 miles north of Kauai, while a ridge aloft remains over the state. As a result, a moderate to breezy and stable trade wind flow persists across the island chain.

Shallow batches of moisture are currently affecting windward Kauai and Big Island, where a quarter to a half inch of rainfall has been observed during the past six hours. Less than a quarter of an inch of rain was measured on windward Maui County and Oahu during this time, and all leeward areas have been dry. Expect continued modest windward rainfall through tonight, followed by slightly drier conditions Saturday.

A slight increase in the breezy trade winds is expected by Sunday, as the high to the north builds to around 1034 millibars. Stable conditions will persist, limiting shower activity to windward and mountain areas. A somewhat drier air mass will push leeward dew points into the low to mid 60’s as early as Saturday afternoon, leading to daytime minimum relative humidity around 45 per cent through at least to the middle of next week.

Remnant moisture from Post-Tropical Cyclone Douglas may reach the state on continued breezy trades, and cause an increase in shower activity late Thursday or next Friday.

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 Friday morning: 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:  Electric Trucks Closer to ‘Tipping Point’ Than Many Realize – and Cities Can Lead the Way

Cities hold the key to accelerating the transition to electric freight and boosting energy security, new analysis from C40 Cities, University of Exeter and Arup reveals.

Heavy-duty vehicles – though less than 10% of the global commercial vehicle fleet – account for 25% of transport-related CO2 emissions and are expected to see a doubling in global demand by 2050.

While progress is being made in China and Europe, the global transition to electric freight remains uneven – with battery limitations, charging times, grid capacity and infrastructure gaps making trucks harder to decarbonize than passenger vehicles. In 2025, only 8% of trucks sold were electric, compared with 25% for passenger cars.
