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: Sea breezes this morning will begin to transition back to trades and persist through the remainder of the week under a deep, upper-level ridge building well north of the islands. By Friday night, a weak frontal band will briefly enhance trade wind showers. Noticeably cooler and drier conditions will follow thereafter beginning by the weekend.

Hawaii’s Weather Details: Remnants of a front will linger just northwest of the Kauai, producing little to no precipitation across the Garden Isle. Sea breeze-drive winds continue today, producing only limited shower activity statewide. Latest ECMWF and GFS model guidance remain in strong agreement, show casing a deep upper-level ridge building well north of the islands. An associated surface high is forecast to move over the islands mid-week, signaling the transition back to a trade wind regime.

Trades will prevail through much of the outlook period, gradually strengthening throughout the week. These winds will play a key role in dispersing firework smoke from the anticipated New Year’s Eve celebrations statewide.Overall, stability will dominate, with shower activity confined to windward and mountain areas.

Toward the latter part of the week, guidance hints at a weak, cold front advancing southward across the islands, briefly enhancing trades and associated shower activity, predominately over windward and mountain locations, with potential for isolated showers spilling into leeward and interior areas.

Thereafter, a noticeably cooler and drier air mass in the wake of the aforementioned front will move into the state, resulting in lower humidity levels beginning the weekend. Needless to say, cooler and drier conditions are in the foreseeable future for the first few days of 2026, which will provide us one of our first tastes of winter coolness.

Hawaii’s Marine Environment: The remnants of a frontal boundary are located northwest of Kauai. This boundary will continue to weaken and drift to the west over the next couple of days. Moderate to fresh east to southeast winds will prevail over the area, but a transition back to locally breezy trade winds will occur by mid-week as high pressure builds back into the region.

A large, medium period northwest (330-340 degree) swell will arrive and spread down the island chain. Surf forecast for most north and west facing shores has been bumped up slightly from previous forecasts, and a High Surf Advisory (HSA) has been issued for north and west facing shores of Niihau, Kauai, Oahu, Molokai, and north facing shores of Maui. Additionally, an overlapping long period north-northwest swell will build tonight and will likely push surf to slightly higher HSA heights by Tuesday. This swell will gradually decline through the remainder of the week.

A slight increase in choppy east shore surf is expected tonight though mid-week as trade winds rebuild. Surf along south facing shores will remain tiny to small through the forecast period.

Interesting: Disease and Trauma Found in Majority of Whale, Dolphin Strandings

From land–borne pathogens to high–speed vessel strikes, Pacific whales and dolphins are caught in a “perfect storm” where human-caused trauma and infectious diseases were found in more than 65% of investigated strandings.

A study spanning nearly two decades by University of Hawaii at M?noa researchers provides insights into the threats whales and dolphins face in the Pacific Islands.

Based on 272 stranding investigations of 20 cetacean species between 2006 and 2024, the study provides foundational data to better manage and conserve Hawaii’s whales and dolphins.
