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.

It’s mostly clear with some windward cloudy areas early this morning, with a cold low temperature of 46 degrees at my place.

Hawaii’s Broad Brush Weather Overview:  Southeast low level winds will bring increasing temperatures and humidity, and light showers (mainly windward and mountain areas) through Tuesday. A cold front will move into the western end of the state Tuesday night. Increased moisture will linger for several days, possibly all the way into the weekend. Flooding risk is small but worth mentioning as we await clarity in the long range models.

Hawaii’s Weather Details:  Radar has been indicating light showers overnight, mainly on the southeast side of Big Island, but also a few light showers spread over pretty much all of the islands. Satellites continue to show some cloudy skies as low level clouds move in from the southeast, and high level clouds move in from the northwest.

Low level winds have veered around to southeast as expected, and this will bring warmer and more moist air our  way. Winds will continue to veer through Tuesday, leading to progressively warmer and more humid conditions. They will become light enough to allow for a sea- and land-breeze pattern in some areas later today and Tuesday. A cold front will approach Kauai County Tuesday night, likely passing through around midnight.

Latest guidance is still showing a variety of solutions on timing and extent of the eastward movement of the front. Latest best guess is that it will stall near Oahu Wednesday afternoon. Thursday and Friday, there are roughly equal chances that the front then gets pushed to near the Big Island, or alternatively pulls back west toward Kauai. Either way, moisture will increase over the state and the chance of rain increases over all islands. This has as much to do with increasing moisture coming in on southeast low level flow over the eastern part of the state, as it does moisture from the front itself.

Models also indicate that the extensive moisture could well remain over the state all the way through the coming weekend. Overall, it will be a return to a wetter and warmer pattern. There is a small risk of thunderstorms, heavy rain, and flooding, but details are still too murky to be confident in specific timing/location at this point.

Hawaii’s Marine Environment:  The Small Craft Advisory (SCA) has been trimmed back to the typical windier waters near Maui County and the Big Island. Winds are on the decline, lingering in these areas for the time being. Seas however have fallen below SCA levels. The swell responsible for the SCA seas, and the High Surf Advisory (HSA) is on the decline, and the resultant surf has fallen below HSA levels.

Winds will continue to weaken as a cold front approaches the islands from the northwest. The front is expected to enter the northwest offshore waters tonight, and reach the coastal waters northwest of Kauai Tuesday night. Isolated thunderstorms over the northwest offshore waters are possible with the front’s arrival. The front will weaken as it enters the coastal waters, and is expected to stall over central coastal waters Wednesday into Thursday.

The current northwest swell will continue to subside. As mentioned above, the resultant surf has fallen below HSA levels. Another moderate, long period, northwest swell is expected to arrive in the islands Tuesday, and linger into the middle of the week, and slowly subside during the end of the week. This swell will maintain elevated surf near advisory levels along north and west facing shores.

There are no noteworthy swells for the next few days for east and south facing shores.

Interesting:  Decoding the Arctic to Predict Winter Weather

Every autumn, as the Northern Hemisphere moves toward winter, Judah Cohen starts to piece together a complex atmospheric puzzle. Cohen, a research scientist in MIT’s Department of Civil and Environmental Engineering (CEE), has spent decades studying how conditions in the Arctic set the course for winter weather throughout Europe, Asia, and North America. His research dates back to his postdoctoral work with Bacardi and Stockholm Water Foundations Professor Dara Entekhabi that looked at snow cover in the Siberian region and its connection with winter forecasting.

Cohen’s outlook for the 2025–26 winter highlights a season characterized by indicators emerging from the Arctic using a new generation of artificial intelligence tools that help develop the full atmospheric picture.

Looking beyond the usual climate drivers: Winter forecasts rely heavily on El Niño–Southern Oscillation (ENSO) diagnostics, which are the tropical Pacific Ocean and atmosphere conditions that influence weather around the world. However, Cohen notes that ENSO is relatively weak this year.
