Hawaii’s MountainsHere’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 at home through the winter in upper Kula, Maui

It’s clear here in Maui County early this morning, with just a few minor low clouds along the windward side…with a chilly low temperature of 49 degrees at my place, with the relative humidity 77 percent.

The clear skies this morning are giving way to increasing clouds early this afternoon, with a temperature of 71 here at my place, with a relative humidity level of 58%.

It’s very cloudy late this afternoon, and we’re having a very light shower here in upper Kula, with a temperature of 63.1 degrees…and the relative humidity is 72%

554pm, cloudy and foggy with a light shower, temperature here at my place is 62 degrees, with the relative humidity 75%…along with calm winds.

608pm, as noted below, there are two cold fronts taking aim on our islands, and after just looking at the latest computer models, I see two more next week, one of which looks like it could be the strongest of the 4…time will tell.

Incredible Lava flow Fountain on the Big Island – December 6th

 

Hawaii’s Broad Brush Weather Overview: Light winds with land breezes can be expected through tonight. Winds will then become light southwesterly Wednesday as a cold front approaches from the northwest. The front should reach Niihau and Kauai Wednesday night, then stall near Maui Thursday night.

Passing moderate showers may accompany this first front. Winds will turn light and northerly after the front passes, then potentially turn southerly again Friday into the weekend. Another stronger front looks to approach this weekend, and heavy rain is possible, as this cold front could have more upper level support.

Hawaii’s Weather Details: A surface ridge just to the north of the islands will gradually weaken tonight and Wednesday, as a cold front NW of Kauai approaches. Light and variable winds with local land breezes tonight should give way to light southwesterly winds with local sea breezes Wednesday morning. Dry conditions are expected ahead of this front with little rainfall expected for most of the day Wednesday.

The front is forecast to approach Kauai Wednesday night, Oahu Thursday morning, and then wash out over Maui county on Thursday evening. Showers will generally be most abundant within the front, but could form over any island interiors during the afternoon hours with the sea breezes. Cool, light northerly winds can be expected behind the front, becoming northeasterly by Friday morning with land/sea breezes.

Winds are forecast to start veering to the south by Friday evening, then to the southwest by Saturday, ahead of the next anticipated cold front. These southerly winds will push brief showers over south facing portions of the islands, but overall stay light. By late Saturday into early Sunday morning, a stronger and wetter cold front could impact the islands.

The front looks to be very moisture rich, with upper and mid level support, stalling near or over the western half of the state. Something worth mentioning is the fact that the upper level trough that is driving this front southward, is much stronger than we have seen so far this season. Additionally, forcing factors such as upper level divergence and low level convergence elevates the chances of sustained heavy rainfall.

Fire weather: Conditions should remain below critical fire thresholds through the week as winds remain light and RH elevated. Temperature inversion heights over Maui and the Big Island will range from 6,000 to 7,000 feet for the time being.

Hawaii’s Marine Environment: A ridge of high pressure north of Hawaii will erode from the west, as a front approaches the state from the northwest. Gentle to moderate easterly winds will weaken to light to gentle speeds and veer south to southeast, then southwest by Wednesday as the front approaches.

The front will move west to east across the state late Wednesday into Thursday, with moderate northerly winds briefly filling in behind the front, before it dissipates over Maui County Thursday night. Light southerly winds will redevelop Friday into Saturday as another front approaches the state from the northwest.

The first of two long to medium period overlapping northwest (310-320 degree) swells will continue to fill in, building surf heights along north and west facing shores to near average. Forerunners of the second, slightly bigger swell will arrive tonight and peak Wednesday.

Surf heights along north and west facing shores could reach marginal High Surf Advisory (HSA) levels Wednesday and hold into Thursday, before slowly subsiding into the weekend. A moderate, long period northwest swell (320 degree) may gradually fill in over the weekend keeping surf from going flat.

Small, choppy east shore surf will become minimal over the next few days, as trades near and upstream become disrupted by approaching fronts. Expect minimal surf for south facing shores, with only a minor south-southwest pulse expected Wednesday afternoon into Thursday, keeping south shore surf heights just above flat levels.

Interesting:  Testing Drones for Mars in the Mojave Desert

Researchers from NASA’s Jet Propulsion Laboratory monitor a research drone in this September 2025 photo. This flight occurred in Dumont Dunes, an area of the Mojave Desert, as part of a larger test campaign to develop navigation software that would guide future rotorcraft on Mars. The work was among 25 projects funded by NASA’s Mars Exploration Program this past year to push the limits of future technologies.

Whether it’s new navigation software, slope-scaling robotic scouts, or long-distance gliders, the technology being developed by the Mars Exploration Program envisions a future where robots can explore all on their own — or even help astronauts do their work.
