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 here at home in upper Kula, Maui, Hawaii, as my 6-week working vacation concluded yesterday.

917am, it’s mostly clear along with some high cirrus clouds here on Maui, My low temperature here at my Kula weather tower was 52.5 degrees, I’m about to drive down to Makawao for join in with many of my friends to play Pickleball.

320pm, yesterday afternoon clouded up lots here in upper Kula, with dense fog and a brief shower. This afternoon, at least so far, is far less cloudy, with lots of sunshine beaming down at the time of this writing. In addition, there was lots volcanic haze yesterday, and looking out the window here at my place, we find thick vog again today.

 

>>> Highest Temperature Wednesday, May 6, 2026 – 103 degrees near Hidalgo, TX
>>> Lowest Temperature Wednesday, May 6, 2026 – 1 degree at Peter Sinks, UT

 

Hawaii’s Broad Brush Weather Overview…as of Wednesday afternoon:  The light winds and humid conditions we have had (due to a weak surface trough) will end tonight. Interior clouds and a few showers will continue into the evening hours, followed by partial clearing overnight. Trade winds will return Thursday into Friday, bringing a more typical pattern of mainly windward and mountain showers, with a few afternoon showers spilling over into leeward areas. A slight increase in shower coverage remains possible Friday night through Saturday night. Stronger trade winds and more stable conditions arrive early next week.

Weather Details for the Hawaiian Islands…as of Wednesday afternoon: Skies were partly to mostly cloudy across the state this afternoon, with only a few exceptions. Radar shows isolated showers, mainly over south central Oahu and northeast Molokai. Winds were on the lighter side as trades are just starting to build back into the region. North to northeast winds were seen across Kauai, Oahu, and Maui County, with variable winds on the Big Island.

A weak surface trough that moved through most of the state was centered over the Big Island this afternoon, and will make it past the Big Island this evening. This will allow trades to build in across the entire state tonight and on into Thursday. Initially, wind speeds will be light to moderate, but stronger winds will arrive this weekend (most likely Saturday night into Sunday). Once this increase arrives, winds should be moderate to breezy well into next week.

The return of the trades will also bring back the typical pattern of mainly windward and mountain showers, occasionally reaching leeward areas. precipitable water values will generally be around an inch, which means that heavy rain is unlikely. There will be a short-lived exception from Friday night into Saturday night, when values are forecast to rise to around 1.3 inches.

This increase is due to the combination of a weak upper level trough, and a band of low-level moisture. During this period, there is an increased chance of brief moderate to heavy rain. Long range models show the possibility of even stronger trades developing late next week and beyond, but we will need to get closer in time before we can have reasonable confidence in this solution.

Marine Environmental Conditions…as of Wednesday afternoon: A trough over the central waters will move very little, prompting a weak ind flow to continue across all local waters tonight. Thursday into Friday, a surface ridge building northwest of the state will bring a return of light to locally moderate northeasterly trades. Trades will then strengthen into moderate to locally fresh range by this weekend, as the ridge continues slowly to build north of the islands.

The arrival of the next northwest swell, originating from a gale force low south of Kamchatka, has been delayed somewhat. The forecast is also complicated by the arrival of another moderate period northwest swell tonight. Surf will remain small along north and west facing shores until the arrival of the longer period energy early Thursday, reaching moderate levels (below advisory criteria) later on Thursday into Friday. Surf will then gradually decline over the weekend into early next week.

A small, long-period south swell, generated from a storm-force low that tracked southeast of New Zealand last week, will fill in tonight and likely provide a small bump in south shore surf through the end of the week. Surf along east facing shores will remain below normal during the next several days, due to the lack of strong trades over and upstream of the islands. East shore surf will gradually increase into the weekend, as trades make a slow return.

Interesting:  Snow Cover on Greek Mountains has More Than Halved in Four Decades, Study Finds

Snow cover in the mountains of Greece – an important water source for communities, agriculture and natural ecosystems during the dry summer months – has more than halved over the past four decades, a study has found.

An international team of researchers, led by the University of Cambridge, used a combination of satellite imagery, climate data, terrain maps, and artificial intelligence to analyze how rising temperatures in the Mediterranean region have affected snow cover on the mountains of Greece – a region that is far less studied than other mountain ranges of Europe, such as the Alps or Pyrenees.

Using the tool they developed, called snowMapper, the researchers found that snow cover has declined by 58% in the past forty years, and that the scale of decline has accelerated since the turn of the century. In addition, the snow season is both starting later and ending sooner.
