Hawaii’s Mountains – Here’s a link to the live webcams on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii, and atop the Haleakala Crater (~10,023 feet) 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 Sunday comments:  I’m here at home in upper Kula, Maui

It’s mostly clear with a few high and low clouds here in Maui County early this morning, with a chilly low temperature of 49 degrees at my place, with the relative humidity 71 percent.

555am, it’s still dark so I can’t see if there’s any vog yet, although it wouldn’t be surprising.

125pm, it’s turned cloudy in the upcountry areas, although the sunshine is holding on down country here on Maui.

505pm, it’s partly to mostly cloudy here in Maui County, and dry for the most part. The temperature here at my place is 67.1 degrees, with the RH running 66%…and there’s vog here on Maui.

Interesting Hawaii Web blog: Latest Totals from the Soggy Week of December 14 – 20, 2025

 

Hawaii’s Broad Brush Weather Overview: Expanding sea breezes favor interior clouds and a couple of showers afternoon showers for the next few days. Trade winds return early to mid-week favoring showers windward and mountains. A remnant frontal band will bring a brief increase in trade wind showers Friday night.

Hawaii’s Weather Details: The pattern across Hawaii continues to transition from a stable, high-pressure dominated regime, to a more complex setup as the upper-level ridge continues to shift eastward, while a surface front stalls just west-northwest of the western islands. Low-level winds will continue to veer southeasterly as the more typical northeast-easterly trades have shifted east.

Aloft, a weakening upper-level trough will slide by north of the islands, while a more distinct mid-to-upper level trough will approach from the northwest by Monday and Tuesday. The lower heights and weakening mid-level cap will allow for some uptick in instability, particularly over the western islands (Kauai and Oahu), which along with the deeper moisture, will lead to increased chances/coverage of showers through Tuesday.

Meanwhile, the eastern islands (Maui and Big Island) will remain under a more stable airmass, as showers will be lighter and more isolated, primarily focused over the windward slopes and interior mountain areas during the afternoon peak heating hours.

By mid-week into the New Year, the models are in fairly good agreement with the return of deep-layer ridging (surface high rebuilding north of the islands), which will herald the return of more typical moderate to breezy easterly trades throughout the Hawaiian Islands. This pattern will likely persist through the first weekend of the New Year, as the  shower chances become confined to the traditional windward and mountain areas.

Hawaii’s Marine Environment: A front will stall west of the state and keep a surface ridge near Kauai. This should allow gentle to moderate southeast to south winds to persist across most waters, and locally fresh east to southeast winds around Big Island. The ridge will retreat northward Monday, allowing east to southeast winds to develop across the island chain.

Easterly trade winds will strengthen Tuesday and Wednesday as broad high pressure builds to the north, and a Small Craft Advisory (SCA) will likely be needed for the typical windy waters around Maui County and the Big Island. SCA conditions may expand to additional waters Thursday as high pressure builds north of the region.

A small, medium period, west-northwest (290-310 degree) swell will hold and bring small, below average, surf to north facing beaches. A larger, medium period, northwest (330-340 degrees) swell will build through Monday, producing surf near the High Surf Advisory level along north and west facing shores. A slightly larger pulse of overlapping long period north-northwest swell will build Monday night and will likely push surf above the advisory level by Tuesday. Resulting seas may reach the SCA threshold across exposed waters during the peak of the swell. This swell will gradually decline through the remainder of the week.

Small surf will prevail along east facing shores due to a lack of trade winds. A slight increase in choppy east shore surf is expected late Monday though mid-week as trade winds rebuild. Surf along south facing shores will remain tiny to small through the forecast period

Interesting: Gold Particles and Sunlight Can Help Purify Water

Industrial waste, dyes and chemicals all potentially pollute our waters. This is a problem we have to address, but how can water be cleansed of these pollutants in a sustainable manner?

Jibin Antony, a PhD research fellow at NTNU’s Department of Chemical Engineering believes the solution may lie in using something of which we have in great abundance: sunlight.

“We need technologies that are green, affordable and efficient. The sun provides us with an enormous amount of energy, completely free of charge. The challenge is finding materials that can use sunlight to break down pollutants in water,” Antony said.
