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.

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

 

Hawaii’s Broad Brush Weather Overview: Light winds are expected today as a cold front draws closer, and our surface pressure gradient weakens. This front is forecast to reach Niihau and Kauai Wed night, then stall near Maui early Friday. Brief moderate rain may accompany this first front. Another front will approach this weekend, and heavy rain is possible.

Hawaii’s Weather Details: Light winds start out the day, with a few windward showers expected. A compact low will lie east of the state today, although is forecast to have minimal, if any, impact on precipitation amounts across Hawaii, before it moves east, out of the picture, in subsequent days.

A cold front moves into the western islands late Wednesday at the leading edge of a trough, weakening the winds. The model guidance shows good agreement on this overall system, allowing the front to generally move through the Island chain into early Friday. Showers with brief moderate rain are expected to accompany the frontal passage late Wednesday into Friday.

A pair of deep lows follow in its wake, also with good guidance agreement. The polar front gets close enough to the western Hawaiian islands to keep the winds weak, and potentially lead to heavy rainfall Sunday into Monday. The trend in the boundary has been slightly eastward over the past 24 hours…we’ll need to keep an eye on this, in case the trend continues and places more of Hawaii at risk.

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 6,500 to 7,500 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.
