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 at home here in upper Kula, Maui, Hawaii

452am, it’s very foggy here in upper Kula with calm winds, and a low temperature at my place of 62 degrees…with the relative humidity 88%

429pm, It was cloudy this morning, and it looked as if it was going to be another wet day, although we finally got rid of that trough to the west, and that blob of moisture finally moved through, and is to the west of the islands now too. Therefore, it has turned more sunny today, and it’s dried out nicely.

 

>>> Highest Temperature Wednesday, June 24, 2026 – 116 at Death Valley, CA
>>> Lowest Temperature Wednesday, June 24, 2026 – 29 degrees at Peter Sinks, UT

 

Hawaii’s Weather Highlights…as of Wednesday evening: Moderate to breezy trade winds can be expected through the weekend and likely into the first half of next week, pushing showers over mostly windward and mountain areas. These showers will be more active during the night time and early morning hours. A mid level and upper level trough could occasionally allow some of these showers to be a little heavier than normal.

Weather Commentary…as of Wednesday evening: Imagery shows an upper level low centered 600 miles northeast of Hawaii. At the surface, breezy trade winds are driven by a 1033 millibar high centered 1200 miles north of Hawaii. While most of the moisture along a surface trough that moved through the state yesterday has tracked away to the west, incoming pockets of low clouds and showers will continue to pass through the islands from now through the weekend.

Nighttime and early morning hours along windward slopes will the prime time and location for a majority of the showers. Isolated leeward showers will also be possible across the smaller islands, and along the Kona slopes during the afternoons. The upper low and surface high will remain mainly stationary into next week, resulting in the overall rainfall amounts/intensity less than Tuesday, but not completely dry.

Long range guidance suggests another influx of moisture possibly arriving by the middle of next week. There are some differences in model solutions regarding trade wind speeds due to the forecast strength and position of the high pressure to the north. This influx of moisture will have a tropical source, and may be the remnants of an area of disturbed weather now being referred to as Invest 94E…which is located in the eastern Pacific at this time.

Marine Conditions…as of Wednesday evening: A surface high will remain nearly stationary north of the state through the week, generating moderate to locally strong trades. Trades will persist through the weekend with minor fluctuations in speeds, as the high shifts northeast of the state and gradually strengthens. A Small Craft Advisory (SCA) remains in effect for select waters across the state. The SCA will likely be extended for the typically windier waters around Maui and the Big Island through the weekend as breezy trades hold.

A series of small to moderate, medium to long period south and southeast swells will keep surf along south facing shores elevated into the weekend. A small, long period south swell will peak Thursday with head high to overhead surf heights at most exposed south shore surf breaks. Additional small pulses of south swell energy arrive on Saturday and Sunday.

Surf along east facing shores will gradually build then hold into the weekend as breezy trades persist. West facing shores will remain on the small side with a slight south swell wrap. Surf heights along north facing shores will increase, due to tiny background northwest swell energy.

Central and Western Portion of the East Pacific:

Invest 94E

Showers and thunderstorms are becoming less organized in association with an area of low pressure located several hundred miles southwest of the southern tip of the Baja California Peninsula. This system is moving quickly westward toward cooler waters, and its chances of becoming a tropical depression are decreasing.

* Formation chance through 48 hours…low…20 percent
* Formation chance through 7 days…low…20 percent

 

Central and Western East Pacific:

A low pressure system is likely to form this weekend or early next week over the central portion of the East Pacific basin. Environmental conditions are forecast to be conducive for gradual development, and a tropical depression is likely to form by the early to middle part of next week as the system moves westward to west-northwestward at 10 to 15 mph.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…high…70 percent

Interesting:  UK Rivers Face Rising Risk of Climate ‘Whiplash’

Climate change could push UK rivers to dangerous extremes and see more frequent rapid swings between wet and dry conditions – a phenomenon known as hydro-climatic whiplash – according to research led by the University of East Anglia (UEA).

Researchers analyzed almost 700 river catchments across the UK to project how river flows may change at 2°C and 4°C of global warming.

The results reveal stark regional contrasts and growing challenges for communities and water managers trying to plan for flood and drought risk – particularly in areas that will increasingly experience both.
