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.

~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Sunday comments:  I’m home here in upper Kula, Maui, Hawaii. I hope you have a good day wherever you happen to be spending it.

It’s clear here in upper Kula early this morning, with some high cirrus clouds, and the low temperature was a cold 46.5 degrees.

242pm, it’s clear to partly cloudy here in Maui County, with just a little leftover haze in our skies.

431pm, it’s become cloudy along these leeward slopes of the Haleakala Crater, and chilly too, with a temperature of only 65.1 degrees at the time of this writing.

Weather Wit of the day:  Blizzard – Snow white and the seven drifts

 

Hawaii’s Broad Brush Weather Overview:  A relatively dry and stable airmass will persist through mid-week. Light to moderate east-southeast trades will hold through Tuesday, before veering more southerly through mid-week ahead of an approaching cold front.

This pattern will allow for clouds and light showers to focus along windward and mountain areas, as well as leeward and sheltered areas with afternoon sea breeze development. Land breezes should help to clear out leeward and interior areas each night.

Chances of rainfall may increase late in the week into next weekend, as the tail-end of a cold front approaches the island chain from the northwest.

Hawaii’s Weather Details:  Radar and satellite imagery show clouds with light showers moving into windward coasts and slopes. High clouds appear to be thinning out over the state, especially around the Big Island. A surface ridge centered far northeast of the state is generating light to moderate east-southeast trades. This surface ridge combined with mid level ridging building in from the west, and a dry airmass moving in from the east will allow for dry and stable conditions to persist through mid-week.

High pressure to the northeast will weaken tonight and shift south through Tuesday, allowing the local pressure gradient to relax, thus weaken winds. Weaker winds across the western half will allow for land/sea breeze regime to dominate, with afternoon clouds and showers forming over a few leeward and interior areas. The eastern half of the state will see more of hybrid trade wind and land/sea breeze pattern, with showers favoring windward areas overnight and leeward slopes of the Big Island each afternoon.

Wednesday through Thursday, winds will veer more southerly over the western half and east-southeast over the eastern half of the state, as a cold front approaches the state, and the surface high shifts eastward. The east-southeast flow may also allow island plumes (downstream convergence from island terrain) to bring showers to leeward areas at times. However, even as the atmosphere moistens a bit, with small pockets of moisture riding in on the lighter east-southeast flow, mid level ridging will strengthen over the area and help to suppress shower activity…so mostly dry and stable conditions should continue through mid-week.

A cold front may pass north or move through portions of the state near the state late in the upcoming week. Model guidance indicates an increase in chances of rainfall and rainfall intensity, particularly for the western half of the state. No major weather concerns are expected at the moment, due to weak surface convergence, along weak upper level support.

Hawaii’s Marine Environment:  A weak surface ridge will remain north of the Hawaiian Islands through Wednesday, and then drift over the island chain from Thursday onward. Light to moderate east-southeast winds will prevail in a fairly stable weather pattern.

A long period northwest swell that is currently moving through the region will begin to decline. Two northwest swell pulses will move into the Hawaii region over the next few days. The first northwest swell pulse will build in tonight into Monday, with surf heights along north and west facing shores approaching advisory thresholds. The forerunners of a larger long period northwest swell will then build quickly into the islands from Monday night into Tuesday, then holding near warning levels through Wednesday.

Surf heights with this swell will easily exceed High Surf Advisory (HSA) levels and possibly reach High Surf Warning (HSW) levels along exposed north and west facing shores. This swell will gradually decline through Friday. Forecast guidance shows a very large medium period northwest swell building into the region by next weekend starting on Saturday, once again surf heights will swiftly exceed HSA levels and approach HSW thresholds through much of the weekend.

Surf heights along east and south facing shores will remain small.

Interesting:  Microplastics Discovered in Antarctica

Scientists have discovered microplastics in the snow near some of Antarctica’s deep field camps, revealing how far-reaching plastic pollution has become. While not new, it’s the first time these tiny pieces of plastic have been found in remote locations.

The study was conducted at field camps, at Union Glacier and Schanz Glacier (near the Ellsworth Mountains), where researchers were carrying out field work, and the South Pole where the US Antarctic Program has a research station. It is first time a new and advanced technique has been used to detect microplastics as small as 11 micrometres (about the size of a red blood cell) in the snow in Antarctica. The study is published this week (6 February 2025) in the journal Science of the Total Environment.

The findings surprised the team as microplastics were found at concentrations ranging from 73 to 3,099 particles per litre of snow. Most of these particles (95%) were smaller than 50 micrometres (0.005 cm, the size of most human cells), suggesting previous studies may have underestimated the extent of microplastic pollution in the region due to less sensitive detection methods.
