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 Tuesday comments:  I’m here in upper Kula Maui as we head into this last month of 2025

It’s clear here in Maui County early this morning, other than some low clouds along the windward coasts and slopes…with a very cool low temperature of 45 degrees at my place.

Hawaii’s Broad Brush Weather Overview: Stable and dry conditions with light southeasterly winds will continue into Wednesday. Expect daytime sea breezes and nighttime land breezes during this time. A weakening cold front will approach from the northwest, increasing the chance of showers for the western islands Wednesday.

Trade winds will build back into the Hawaiian Islands area Thursday onward, returning a more typical trade wind weather pattern, with off an on passing showers along windward and mountain areas, especially during the overnight to early morning hours.

Hawaii’s Weather Details: Satellite imagery shows a band of clouds associated with a weakening frontal boundary roughly 500 miles northwest of Kauai this morning. High clouds ahead of the front continue to break apart and thin out over the state. Meanwhile, a high pressure ridge remains in place over the island chain, which will result in yet another day of stable conditions and light southeasterly ground winds.

This morning atmospheric soundings show inversion heights between 5,000 to 6,000 feet from Kauai to Hilo, respectively. Mainly scattered light showers can be seen passing over windward and mountain areas of the the Big Island and Maui early this morning. Given the light wind flow, expect daytime sea breezes to increase interior clouds over the islands this afternoon, and clear tonight as land breeze circulations resume.

Models continue to show the front mentioned above to gradually weaken as it approaches the state through today, and possibly moving over Kauai Wednesday before stalling. As this occurs, shower activity will likely increase over Niihau and Kauai for 12 to 24 hours, until the front breaks apart and slowly retrogrades westward away from the islands.

Differences between the various models remain, with the ECMWF notably showing wetter trends for the islands in Kauai County. The GFS, however, continues to favor a drier solution, where the weakening boundary stalls and then moves back westward away from the state before reaching the Garden Isle. Mid and upper level ridging will remain over the state limiting cloud height, thus don’t expect any significant heavy rainfall with this event.

A surface high pressure system northeast of the state will gradually build as the remnant front weakens west of the state Thursday. This will strengthen wind speeds from east to west across the state, and back winds to more of an easterly direction by Thursday night into the weekend. Expect more of a typical trade wind shower pattern to return during this time with brief passing showers forecast along windward and mountain areas, favoring the overnight to early morning hours each day.

Fire weather:  Critical fire weather conditions are not expected this week. Although stable and dry conditions will persist through Wednesday, winds will remain below critical fire weather thresholds. Locally breezy trades will return during the second half of the week, but increased relative humidity is expected.

Hawaii’s Marine Environment: A weak surface ridge will remain over the area and maintain light to moderate southeast background flow. This pattern will allow for daytime sea breezes and nighttime land breezes along waters adjacent to the coasts. A cold front, currently northwest of the state, is forecast to approach Kauai on Wednesday, then stall and weaken into a trough by Thursday.

The trough is projected to retrograde back westward, away from the state. Late Thursday through the weekend, a ridge of high pressure building north of the region, will bring a return of moderate to locally strong easterly trades. A Small Craft Advisory may be needed for the typical windier zones surrounding Maui and the Big Island.

The current moderate, medium period, northwest swell (310-330) will continue to slowly lose energy. Thus, the High Surf Advisory was cancelled for all islands. A series of northwest to north-northwest (310-340 degree) swells are expected during the second half of the week, with each pulse becoming slightly bigger and veering with each passing day.

The first pulse, a medium period northwest swell, will begin to fill in on Wednesday, and generate surf just shy of advisory levels. A slightly larger and longer period pulse is expected on Thursday out of the northwest, followed by a slightly larger north- northwest on Friday.

Surf heights should exceed advisory thresholds Thursday through through Saturday, with the peak approaching warning levels late Thursday into Friday. A Small Craft Advisory for high seas affecting exposed waters, may be needed during the peak of the event.

East shore surf will remain small through Thursday due to weak winds, then become choppier as trade winds increase Friday through the weekend. Expect minimal background energy for south facing shores through much of the week.

Interesting:  The July 4 Floods in Texas Weren’t a One-Off. They Were a Warning

On July 14 this past summer, I pulled up to the Kerrville Kroc Corps Community Center, dodging puddles and sinkholes from a recent thunderstorm in a town where the last thing needed was more rain. I was there as a volunteer to help people impacted by the worst flooding central Texas had seen since record-keeping began.

Ten days prior, in the early hours of July 4, heavy thunderstorms in Kerr County led the Guadalupe River to rise 26 feet in less than 45 minutes. At least 135 people were killed, with the most deaths located in Kerr County. And the ramifications of the disaster continue to unfold: the head of FEMA, David Richardson, recently resigned, and lawsuits continue to roll in.

After walking inside the community center with my friend and her sister, we signed in as part of the disaster response volunteer group that focused on receiving and sorting donations, managing intake forms, shopping for specific needs and loading bundled donations into vehicles. As cogs in the wheel of efficiency that seems to only develop during times like this, we were given a quick tour of the community center before we were assigned specific roles.
