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.

~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Aloha Friday 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, although with volcanic haze still around, while my low temperature was 49 degrees.

850am, there’s still lots of vog, although less than yesterday, at least so far.

135pm, terribly voggy again! Partly to mostly cloudy with muggy kona winds…yuck! I don’t typically make judgements on the quality of our weather here in the islands, although this is an exception.

5pm, a slight kona breeze which is bringing up muggy tropical air over the islands from the south. Skies are generally clear with a few minor cumulus clouds.

6pm, extremely voggy as we head towards sunset. The temperature here at my Kula weather is 66.5 degrees after a high of 77 degrees.

712pm, now that it’s dark, I just went out on my weather deck and looked down towards Kihei and Kahului/Wailuku, AND I can’t see the city lights! This has been, and continues to be a prolonged and incredibly bad vog event here in the eastern part of the state at least!

Weather Wit of the day:  Hurricane Watch – The mull before the storm

 

Hawaii’s Broad Brush Weather Overview:  Southerly winds will persist across the western half of the state, while southeasterlies persist across the eastern half through Saturday, focusing light showers over leeward and mountain areas. Trade winds will return by Sunday and focus showers over windward areas, with a wetter pattern starting Tuesday.

Hawaii’s Weather Details:  A cold front approaching the islands from the northwest will stall today, as it encounters mid to upper ridging that is centered over and east of the islands. The position of the surface ridge going into the weekend will continue to promote a gentle southerly wind pattern over more western islands, and southeasterly breezes across the eastern half of the state.  With little change in the pattern over the Central Pacific, this trend will continue through Saturday.

A weaker wind regime will also lend itself to more localized breeze activity, as afternoon sea breezes thicken cloud cover and introduce light showers to communities upcountry. The front northwest of Kauai is stalling north of the area, and will keep its attendant moisture and more widespread showers north of the island chain. The western half of the state will experience more cloud cover and shower activity over leeward areas within this southern flow regime. Southeasterly flow will allow for more cloud build ups and frequent showers that will favor southeast-facing coasts and mountain slopes of the Big Island and Maui County.

A surface ridge southwest of high pressure centered far northeast of the area, will remain draped over the islands this weekend, as mid to upper level ridging builds in overhead. Warm and muggy conditions will persist as this gentle southerly flow maintains elevated humidity levels. While a series of fronts pass by north of the state and provide minor fluctuation in wind behavior, this general southern wind pattern will remain in place through Sunday. Rainfall accumulation will be very minimal through the weekend.

A new front approaching from the northwest early next week will likely dissipate just before it reaches the state. Strong ridging at all levels will expand in north of the state. A large surface high moving to the east north of the chain will be the impetus of returning breezy to locally windy trade winds going into the middle of next week. Ribbons of higher moisture arriving on newly established trades, along with a touch more instability in response to cooler temperatures aloft from a trough passing far north of Hawaii, may lead to a more wet trade wind pattern late next week.

GOES imagery, surface and air quality observations show vog continuing to impact the majority of the state from Big Island to Oahu. SO2 emissions from areas of Kilauea’s Halema’uma’u crater are being caught up and transported within the south-southeast lower level winds. The most recent eruption did pause this morning, and this will likely lead to a reduction in overall emissions and subsequent vog coverage the next several days. As trades build back in early next week, any lingering upstream vog will be carried westward across the islands. Vog concentrations will likely thin out as strengthening trades better mix out haze.

Hawaii’s Marine Environment:  A front just north of Kauai will lift northward, with a new front then approaching from the west over the weekend. Light to moderate southerly winds will prevail over the western islands through Saturday, while light to moderate east-southeasterly winds hold over the eastern end of the state. The new front will stall and weaken into a trough west of the islands Sunday and Sunday night, allowing trade winds to gradually fill in and strengthen. A new high building north of the state early next week, will bring strong trade winds back to the island chain.

A large northwest swell will continue to build from northwest to southeast down the island chain, peaking then gradually lower tonight through the weekend. A High Surf Warning is now in effect for north and west facing shores of most of the smaller islands through 6am Saturday. A Small Craft Advisory is also in effect due to elevated seas for most marine zones though 6am Saturday. A High Surf Advisory has been issued for west facing shores of the Big Island through 6am Saturday. Advisory level surf will likely linger for most of the areas under the current headlines though the day Saturday.

A new moderate to large northwest swell is due in early next week, which could bring another round of advisory level surf to most north and west facing shores Monday and Tuesday. This swell will then gradually lower through Thursday with a new large northwest swell possible late next week.

Surf along south facing shores will remain very small through late next week. Surf along east facing shores will remain very small through the weekend. East shore surf will begin to rise with the returning trades Monday and Tuesday, with surf rising to above normal levels by the middle of next week.

Interesting:  Microplastics in Ocean Linked to Disabilities for Coastal Residents

Mobility, self-care, independent living disability higher in areas with high microplastics.

Tiny bits of plastic found in the ocean may be tied to a higher risk of disability for people who live in coastal areas with high levels, according to a preliminary study released February 25, 2025, that will be presented at the American Academy of Neurology’s 77th Annual Meeting taking place April 5–9, 2025, in San Diego and online. The study looked at disabilities affecting memory and thinking, mobility and a person’s ability to take care of oneself.

The study does not prove that microplastics cause disabilities; it only shows an association.

Marine microplastics are microscopic pieces of plastic, less than 5 millimeters in length, found in oceans and seas. They come from broken-down plastic trash or products like face scrubs, fishing nets and food wrappers or take-out containers.
