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 working vacation concluded yesterday.

 

>>> Highest Temperature Tuesday, May 5, 2026 – 105 degrees at Rio Grande Village, TX
>>> Lowest Temperature Wednesday, May 6, 2026 – 1 degree at Peter Sinks, UT

 

Hawaii’s Broad Brush Weather Overview…as of Wednesday morning:  Light winds and humid conditions will persist today, as a weak surface trough lingers near the state. Interior clouds and a few showers will develop during the afternoon hours, followed by partial clearing overnight.

Trade winds will gradually return Thursday and Friday, bringing a more typical pattern of mainly windward and mountain showers, with a few afternoon showers over leeward areas. A slight increase in shower coverage remains possible this weekend as an upper disturbance approaches the islands, followed by stronger trade winds and more stable conditions early next week.

Weather Details for the Hawaiian Islands…as of Wednesday morning: The humid land and sea breeze pattern with dewpoints hovering in the mid to upper 60’s, will continue today as the weak trough meanders near the central portion of the island chain. Expect mostly sunny conditions for most areas this morning, followed by another round of interior and leeward clouds and isolated to scattered showers this afternoon. Shower chances may remain slightly enhanced near central islands where the trough is located. Accumulations, however, should remain light due to mostly stable conditions and plenty of dry air above a strong inversion positioned around 7,000 feet.

Light to moderate trade winds will gradually return Thursday and Friday as the subtropical ridge rebuilds north of the state. Showers will become more focused over windward and mountain areas, though localized afternoon sea breeze clouds and a few showers may still develop over sheltered leeward terrain.

By the weekend, an upper-level disturbance approaching the region could lead to a slight increase in showers, though uncertainty remains elevated due to model differences regarding the timing and strength of these features. More stable conditions and stronger trade winds are expected to return early next week.

Marine Environmental Conditions…as of Wednesday morning: A trough north of the smaller islands will move very little today, and allow for a weak wind flow to continue across all local waters. Thus, expect diurnally driven late morning and early afternoon sea breezes to develop along waters near the immediate coasts.

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 the weekend.

A moderate medium-period northwest swell will gradually fade. A new long period swell, originating from a gale force low south of Kamchatka, will build tonight and give another boost to north and west shore surf Thursday and Friday, but should remain below advisory levels. Surf will 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 today, 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. Surf along east facing shores will get a small bump up into the weekend as trades gradually increase.

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.
