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 Monday comments:  I’m here at home in upper Kula, Maui

It’s mostly cloudy with variable high and middle level clouds here in Maui County early this morning, with a chilly low temperature of 49 degrees at my place, with the relative humidity 62 percent.

It’s partly cloudy early this afternoon, with a mix of high and low clouds covering us. I’ve played Pickleball the last two mornings in Haiku, although I’ll take a break tomorrow.

It’s very cloudy here in upcountry Kula early this evening, and I have a temperature of 62.9 degrees, compared to a warmer 79 degrees down at the AP in Kahului.

825pm, it’s mostly cloudy and dry here across Maui County.

Hawaii’s Broad Brush Weather Overview: A cold front lifting north of the islands will allow the ridge to lift northward, resulting in the southeast winds increasing and becoming more easterly. Moderate to locally breezy trades will ring in the new year. Frontal moisture being carried in on the trades for the first weekend of the new year will result in an increase in trade wind showers.

Hawaii’s Weather Details: A stationary front northeast of the islands will dissipate and lift the north, allowing the surface ridge near the islands to lift northward. This is turn will allow the light southeasterly winds over the islands to increase and turn to the east over the next day or two.

A new ridge building in north of the islands mid-week will help trade winds to rebound further. As the frontal boundary moves far northeast of the islands, the southern end will linger northeast of the islands and approach the state Friday, enhancing trade winds showers for the start of the first weekend of 2026.

Mid-level ridging over the islands through the week will help to provide a stable airmass overhead, limiting rainfall amounts. The returning trades will focus showers over the typical windward and mountain areas. The mid-level ridging will also help to maintain typical trade wind inversion heights, but the moderate trade winds New Year’s Eve should help to disperse firework smoke from the New Year’s Eve celebrations state-wide.

As the above mentioned frontal band reaches the islands Friday, we can expect enhanced shower activity, predominately over windward and mountain locations, with potential for isolated showers spilling into leeward and interior areas. Thereafter, a noticeably cooler and drier air mass is expected this weekend.

Hawaii’s Marine Environment: The remnants of a frontal boundary are located northwest of Kauai. This boundary will continue to weaken and drift to the west over the next couple of days. Moderate to fresh east to southeast winds will prevail over the area, but a transition back to locally breezy trade winds will occur by mid-week as high pressure builds back into the region.

A large, medium period northwest (330-340 degree) swell will arrive and spread down the island chain. Surf forecast for most north and west facing shores has been bumped up slightly from previous forecasts, and a High Surf Advisory (HSA) has been issued for north and west facing shores of Niihau, Kauai, Oahu, Molokai, and north facing shores of Maui. Additionally, an overlapping long period north-northwest swell will build tonight and will likely push surf to slightly higher HSA heights by Tuesday. This swell will gradually decline through the remainder of the week.

A slight increase in choppy east shore surf is expected tonight though mid-week as trade winds rebuild. Surf along south facing shores will remain tiny to small through the forecast period.

Interesting: Disease and Trauma Found in Majority of Whale, Dolphin Strandings

From land–borne pathogens to high–speed vessel strikes, Pacific whales and dolphins are caught in a “perfect storm” where human-caused trauma and infectious diseases were found in more than 65% of investigated strandings.

A study spanning nearly two decades by University of Hawaii at M?noa researchers provides insights into the threats whales and dolphins face in the Pacific Islands.

Based on 272 stranding investigations of 20 cetacean species between 2006 and 2024, the study provides foundational data to better manage and conserve Hawaii’s whales and dolphins.
