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’s Broad Brush Weather Overview…as of 317am Tuesday:  An upper level ridge will move in and bring a return to cooler and drier trades through Thursday. Winds will veer to southeast Friday and remain that way into the weekend, bringing warmer temperatures and a sea- and land-breeze pattern. Sunday night into early next week has the potential for another trough to move through with some wet weather.

Moderate to breezy trade winds will blow across our area with decreasing shower trends, as high pressure builds in through Thursday. Winds begin to weaken and veer more southeasterly from Friday into the weekend, ahead of the next cold front approaching the islands from the west.

Hawaii’s Weather Details…as of 317am Tuesday: Radars show scattered showers moving across the island chain. Mostly along windward and mountain locations. Breezy trade winds are ongoing and are expected to remain over the area through Thursday. This will bring additional showers over the next few days, mainly windward and mountain areas.

An upper level ridge of high pressure will finally replace the trough of low pressure that has brought significant rains to the area in recent days. Today through Thursday we will see a typical trade wind pattern. Drier and cooler air will be carried into the region. This will allow for cool mornings in areas sheltered from the trades.

As the upper level ridge axis moves east of the state Thursday night into Friday, our low level flow will veer and become more southeasterly. This will begin to slowly increase low-level moisture. As wind speeds weaken, sea- and land-breezes will develop this coming weekend. This pattern typically results in showers forming both windward and leeward. Long range models show the potential for a trough to bring an increase in showers Sunday night into Monday of next week.

Hawaii’s Marine Environment…as of 317am Tuesday: Strong high pressure remains far north of the state, while a weakening surface trough lingers in the far southeast offshore waters. Northeasterly trade winds look to strengthen to fresh to strong speeds through tonight, before gradually easing to locally strong speeds over just the windier waters and channels around Maui County and the Big Island Wednesday and Thursday. A Small Craft Advisory (SCA) has been expanded to all coastal waters and extended through tonight, due to a combination of winds and mainly seas above SCA criteria, due to the large north-northeast swell currently impacting the islands. An approaching cold front will likely cause winds to decline and veer out of the southeast Thursday night into Saturday.

A large, long period north-northeast (010-030 deg) swell has peaked and will look to hold before declining through the end of the week. This swell will produce breaking waves at High Surf Warning levels across most north and east facing shores through this afternoon.

Due to the direction of the large swell, exposed west facing shores of West Maui, western Molokai, and North Kohala on the Big Island will likely experience High Surf Advisory conditions. The north-northeast swell will gradually decline tonight at High Surf Advisory (HSA) level conditions through Wednesday, before continuing to decline through Friday. In addition to this swell, a small pulse of overlapping west-northwest swell is expected through Wednesday. Due to the direction of the large north-northeast (010-030) swell, some overwash will be possible along low-lying coastal roads and infrastructure in windward areas, especially in the Keaukaha area east of Hilo. Hazardous conditions and heavy surges are expected in north facing harbors, mainly in Hilo and Kahului.

South facing shores will remain tiny due to a small background southwest swell, before flat wintertime surf will continue along south facing shores through the end of the week week.

Interesting:  Research Shows Best- and Worst-Case Scenarios for a Warming Antarctica

Antarctica’s pale expanses of ice keep water locked up and reflect heat from the planet — but the climate crisis is putting these safeguards at increasing risk. Antarctica is warming much faster than the global average, which could destroy its ecosystems and put other parts of the planet at risk by driving sea level rise and damaging food chains.

Now scientists have modeled the best- and worst-case scenarios for climate change in Antarctica, demonstrating just how high the stakes are if we don’t act now — but also how much harm can still be prevented.

“The Antarctic Peninsula is a special place,” said Professor Bethan Davies, lead author of the article in Frontiers in Environmental Science and UK national nominee for the 2026 Frontiers Planet Prize. “Its future depends on the choices that we make today. Under a low emissions future, we can avoid the most important and detrimental impacts. However, under a higher emissions scenario, we risk the loss of sea ice, ice shelves, glaciers, and iconic species such as penguins.
