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.

Glenn’s Thursday comments:  I’m at home here in upper Kula, Maui, Hawaii

It’s partly to mostly cloudy, with calm winds at my place, and with a low temperature of 59 degrees and the relative humidity is 85%

 

>>> Highest Temperature Wednesday, June 17, 2026 – 119 at Stovepipe Wells, CA
>>> Lowest Temperature Thursday, June 18, 2026 – 22 degrees near Mackay, ID

 

Hawaii’s Broad Brush Weather Overview…as of Thursday morning: A weak trough and its associated moisture plume will progress northwestward up the island chain through Friday, bringing a slight increase in shower activity as it passes through. Otherwise, lighter winds will allow for a sea/land breeze pattern to persist into the weekend, with showers developing over leeward and interior areas each afternoon, followed by clearing at night. Trade winds will gradually strengthen late this weekend through next week, shifting the shower focus to windward and mountain areas.

Weather Details for the Hawaiian Islands…as of Thursday morning: A weak surface trough is passing over Molokai and Oahu this morning and will gradually move up the island chain through Friday, before lifting north of the area and dissipating. A plume of moisture accompanying this trough will help bring increased cloud and shower coverage in its vicinity as it progresses northwestward. The positioning of this surface trough and a series of fronts passing well north of the state will keep the trade winds disrupted through the rest of the work week and into the weekend, with generally moderate east-southeasterly winds across the eastern half of the state, and light to moderate east-southeast winds across the western half.

This weaker, slightly veered low- level wind pattern will allow a sea and land breeze cycle to commence, bringing clouds and a few showers across leeward and interior areas each afternoon, and clearing overnight. However, increased cloud cover in the vicinity of the trough may inhibit the sea and land breeze cycle. In addition very warm and muggy conditions will persist through the weekend. Please remember to hydrate and take breaks when you need them. Trade winds will gradually ramp up late this weekend through next week, becoming moderate to breezy by Wednesday as the surface trough weakens and moves westward, and the subtropical high to the far northeast finally regains control over the Central Pacific. Batches of moisture will filter in on the strengthening trades, supporting periodic increases in windward and mountain showers next week.

Marine Environmental Conditions…as of Thursday morning: Trade winds will be mostly at gentle to moderate strength during the next few days, as the surface ridge to the north remains weak and a broad surface trough continues to move through the islands over the next few days. The weak trough is currently located near Maui County and is producing some scattered showers over the coastal and offshore waters. Scattered showers will generally decrease over the coastal waters by Friday. Trades may increase slightly over the weekend, with more pronounced strengthening early next week as high pressure builds to the north.

A series of southern hemisphere swells will continue to move through the area during the next week, though much smaller than the recent large event. Nearshore Lanai and Barber Point buoys is showing an increase in the 16 to 18 second energy bands, associated with a new south swell filling in today. NOAA buoy 51002 is showing around 4 feet of deep water swell with a period of 14 to 16 seconds, with NOAA buoy 51004 SE of the Big Island showing deep water swell of up to 5 feet. With the main fetch aimed just east of the state, surf should remain below advisory thresholds today. The peak of the swell will be today and will gradually decline Friday into the weekend. A series of smaller south-southwest swells will fill in Sunday into the first half of next week, and will maintain surf near seasonal averages through the week.

Small surf will prevail on north and east shores through most of the coming week. A slight increase in east shore surf is expected around next Tuesday or Wednesday as trade winds build across the region.

Offshore East Coast of the United States (Remnants of Arthur):

Showers and thunderstorms associated with a trough of low pressure (the remnants of Arthur) are located over the southeastern United States. Environmental conditions appear marginally conducive for some subtropical or tropical development on Friday or Saturday, as the system moves northeastward at around 15 mph, and emerges offshore the east coast of the United States and into the Western Atlantic Ocean.

Regardless of development, heavy rainfall with the potential for widespread and life-threatening flash flooding is likely across portions of the Southeast United States during the next day or two.

Formation chance through 48 hours…low…10 percent.
Formation chance through 7 days…low…10 percent.

Interesting: From Speed to Stability: How Ageing Changes the Way We Walk

Reasons why our walking becomes slower and more tiring with age have been uncovered by new Australian research — with findings showing the body increasingly sacrifices efficiency to stay upright.

The study, led by Flinders University and the University of Canberra, reveals that as we age, the body adopts a “safety-first” walking style that prioritizes stability at the cost of speed and energy efficiency, which helps explain why older adults tire more easily and face a higher risk of falls.

Analyzing movement data from 107 healthy adults aged 26 to 86, researchers identified subtle but important changes in how the ankle and surrounding muscles control each step.

Lead author and expert in sport and exercise technology, Dr Cody Lindsay, says the ankle plays a critical role in both balance and forward motion.
