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.

1120am, clear to partly cloudy here in Maui County, with much less vog than yesterday. We also have besides the cotton ball cumulus clouds, some nice streaky high cirrus clouds.

4pm, as usual it’s gotten cloudy up here in Kula, with sunshine still going strong down closer to the coast. The temperature here at my place is 67.4 degrees, and we had a few flecks of moisture falling for a couple of minutes.

511pm, we have a light shower with a cool temperature of 63.1 degrees here at my Kula weather tower.

Hawaii’s Broad Brush Weather Overview: A stable southeasterly background flow will persist across much of the state into Wednesday, leading a rather dry land and sea breeze pattern from Oahu to Big Island. A weakening front will stall near Kauai, producing increased clouds and higher rainfall chances on the Garden Isle, mainly Wednesday afternoon and evening. Moderate east to southeasterly trade winds will build across the island chain on Thursday, focusing showers over windward and mountain areas.

Hawaii’s Weather Details: Stable and mostly dry conditions persist under light winds. An advancing front northwest of the state is keeping the subtropical ridge near Kauai, resulting in a generally light southeasterly background flow. This is keeping most islands in the downwind wake of the Big Island, and is allowing a land and sea breeze pattern to dominate. A ridge aloft is maintaining a somewhat strong inversion around 6,500 feet, while precipitable water remains below seasonal normal.

These ingredients continue to produce scant rainfall, even as afternoon sea breezes generate clouds over interior terrain. The southeasterly flow is also carrying some volcanic emissions from recent activity at Kilauea over some of the islands. While air quality sensors continue to show somewhat low concentrations and there is no significant restriction to visibility, some haze persists locally.

Wetter conditions may develop on Kauai Wednesday, while much of the state remains under the rather dry land and sea breeze regime. A trough will develop ahead of the above mentioned front over the coastal waters west of Kauai and Niihau. Expect some increase in shower activity along this feature, but little rainfall is expected over land tonight. The front and trough will merge on Wednesday and drift eastward toward Kauai, bringing increased chances for showers on Kauai during the afternoon and evening.

Since there will be little upper level support for the weak cold front and models depict the feature stalling over or just west of Kauai, widespread heavy showers are not likely, though northern slopes and interior sections of the Garden Isle could experience over an inch of rain in the wettest scenario. Chances for rainfall on Kauai will decrease later Wednesday night, as the old frontal band retreats westward.

Moderate east to southeast trade winds will strengthen Thursday, pushing the deeper moisture away from Kauai. Winds could become locally breezy as shower activity along the old frontal band west of Kauai is enhanced by a trough aloft. This will help tighten the local pressure gradient and induce the surging east to southeast winds over the state. Conditions will remain stable, and typical moisture will produce showers over east and southeast slopes.

Moderate easterly trade winds and a typical pattern of mainly windward and mountain showers is expected Friday through early next week.

Fire weather: Critical fire weather conditions are not expected this week. Winds will remain light through Wednesday, with higher rainfall chances on Kauai. The inversion will hold at 5,000 to 6,500 ft through Wednesday, keeping very dry conditions on the upper elevations of the Big Island and Maui. Moderate east to southeast winds will be below the critical fire weather threshold Friday into early next week. Humidity will be near seasonal normal, and the inversion will lift slightly.

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.
