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.

It’s partly to mostly cloudy early this morning, with a low temperature of 52 degrees at my place…with the RH 76%

 

Weather Wit of the day: You have to look at the good side of winter weather. If it weren’t for coughing and sneezing some people wouldn’t get any exercise at all

Hawaii’s Broad Brush Weather Overview:  Moisture and instability will linger over the islands today, though will gradually decrease by the end of the weekend. Winds will weaken and veer east-southeasterly today, then become light and southerly on Sunday, allowing land and sea breezes to dominate, and drive afternoon showers over interior and leeward areas. Forecast confidence decreases early next week, as one or more weak fronts approach the state, though limited upper-level support should keep rainfall impacts modest.

Hawaii’s Weather Details:  Upper air atmospheric soundings from Lihue and Hilo show that a moist and somewhat unstable air mass remains in place across the island chain, as the inversion has eroded a bit compared to 24 hours ago. Light to moderate easterly trade winds have briefly returned to the state, as surface high pressure continues to slide eastward away from the state. Showers and low clouds during the past twelve hours or so have primarily favored windward and mountain areas, particularly for the island of Maui, and now predominantly Oahu this morning. Meanwhile, ample moisture aloft is resulting in scattered high clouds moving across the region.

As high pressure continues to shift east ahead of the next cold front approaching from the northwest, winds are expected to gradually veer east-southeasterly today, then weaken further and turn southwesterly across the western half of the state by Sunday. As the winds decrease, this will set up a daytime sea breeze and overnight land breeze regime across the islands. Meanwhile, the upper-level trough that has been supplying instability will slowly move off to the east, allowing atmospheric stability to increase from west to east as mid-level ridging builds into the region.

With that being said, moisture and instability will linger today as the upper trough moves over and eventually past the region. This will keep showers in the forecast, and isolated thunderstorms are possible across eastern portions of the island chain for the afternoon. Additionally, with cold temperatures and deep moisture over the summits, snow showers and freezing fog may occur again this afternoon, as daytime heating sparks convection over the Big Island.

By Sunday, instability and moisture will be decreasing, and confidence in thunderstorm chances remains too low to include in the forecast at this time. Isolated to scattered showers will still be possible over interior and leeward areas during the afternoon, where sea breeze induced surface convergence commences.

An unusual amount of uncertainty exists in the forecast early next week, as models still offer wildly different solutions regarding a potential front moving into or through the area. The ECMWF, for example, brings a front into the western part of the island chain by late Sunday night, then shows it quickly moving down the island chain on Monday. This scenario offers a wetter solution and breezy northeasterly winds following the frontal passage. Meanwhile, the GFS keeps the front north of the state, with the island chain remaining in a drier pattern with lighter winds persisting. In any case, even if the front does move into the islands, with mid-level ridging forecast to persist over the state, there would be limited upper-level support.

The rest of the week next week looks to remain fairly dry with light southeasterly winds returning for much of the week. This would once again favor a land and sea breeze regime ahead of another potential front towards the end of next week

Hawaii’s Marine Environment: A high pressure system currently north of the state will drift eastward this weekend, as another front approaches the state from the northwest. Moderate trades will veer from a more southeasterly direction, then become light southerlies tonight into Sunday. Winds should become light enough for near shore land and sea breezes to develop during this time. The tail end of the cold front will likely move into the northwest waters late Sunday into Monday, with fresh north to northeast winds blowing in north of the front.

There is still some uncertainty on how far southeast the front will move into the islands, which will alter the reach and extent of both northerly winds and rain showers over island waters. Highest chances are that the forward motion of this weak cold front stalls near Kauai waters by Monday morning.

The current medium period, north-northwest (330-340 degree) swell will continue to decline. Surf heights will remain elevated as a series of small overlapping northwest swells will pass through the Hawaii region through the weekend into early next week. The first pulse should arrive late Saturday and peak on Sunday, followed by another pulse late Monday. A slightly larger north-northwest (330 degree) swell is expected Tuesday into Wednesday. In the long range, there is potential for a large, long period northwest swell building to warning levels impacting north and west facing shores towards the end of next week.

Surf along east facing shores will remain small into next week due to the lack of persistent trade winds locally and upstream. South facing shores will remain nearly flat through the weekend. A tiny long-period south-southwest swell may produce a slight boost to south shore surf heights from late Sunday into Tuesday.

Interesting:  After L.A. Fires Receded, Indoor Air Pollution Grew, Study Finds

Even after the disastrous L.A. wildfires abated last year, the danger from smoke persisted for many people living nearby. A new study finds that, by some measures, indoor air pollution actually worsened after the fires.

Erupting in January 2025, the Palisades and Eaton fires burned through large areas of Los Angeles, damaged or destroyed more than 18,000 buildings and, by one estimate, killed 440 people. To track pollution from the fires, researchers at UCLA collected air samples across the city, both indoors and out, throughout January as the fires burned and in the weeks that followed.

The researchers tracked levels of volatile organic compounds, or VOCs, unleashed by the burning of paint, carpets, upholstery, and other materials commonly found in homes. “Some of these are carcinogenic and definitely harmful to human health,” said coauthor Yifang Zhu, of UCLA.
