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.

Glenn’s Thursday comments:  I’m here at home through the winter in upper Kula, Maui

It’s mostly clear here in Maui County early this morning…with a low temperature of 51.5 degrees at my place.

The large full moon is sinking down into the western horizon early this morning…a beautiful sight.

Weather Wit of the day: I love those recorded forecasts. I just heard one that said “A hurricane is expected with winds of one hundred and forty miles per hour, tides six feet above normal and ten inches of rain! Have a nice day.”

>>> Highest Temperature Wednesday, December 3, 2025 – 89 near Rio Grande Village, Texas
>>> Lowest Temperature Thursday, December 4, 2025 – minus 21 near Skibo, MN

 

Hawaii’s Broad Brush Weather Overview: As a dissipating front west of Kauai continues to drift away and weaken, southeasterly winds will become locally breezy today, with showers focused along east and southeast slopes of all islands. Trade winds will ease slightly and shift out of the east Saturday into early next week, supporting a typical pattern of windward and mountain rainfall.

Hawaii’s Weather Details: The dissipating front west of the Kauai is expected to weaken to trough by Friday morning, as is continues to drift away from the state. Light southeasterly winds continue across the islands with clouds and showers largely impacting the eastern sides of all islands. A ridge aloft has provided stable conditions, yet a few briefly heavy showers have been reported.

As the front continues to weaken and move to the west, a surface high far to the northeast will build, causing the southeasterly flow across most of the island chain to gradually strengthen. These winds may push a few showers onto the east and southeast facing slopes of the islands.

Moderate easterly trade winds and a typical pattern of showers focused over windward and mountain areas is expected Saturday through early next week. Pockets of moisture moving along the trade wind flow will periodically boost rainfall, but no significant moisture source is noted in the guidance. The GFS and ECMWF model predictions diverge by the middle of next week, though both suggest that trade winds could break down.

Fire weather: Critical fire weather conditions are not expected this week. Light winds will give way to mainly moderate east to southeast winds, but winds will be below the critical fire weather threshold. Humidity will be near seasonal normal, and the inversion will lift slightly from its current range of around 7,500 feet.

Hawaii’s Marine Environment: A stationary front west of Kauai will gradually weaken to a trough and retrograde back westward, away from the islands. Meanwhile, a ridge of surface high pressure building northeast of the state will allow for moderate to locally strong east or east southeast background flow through early Saturday. A Small Craft Advisory (SCA) has been issued until 6am Saturday morning for most of the marine waters surrounding the Big Island and Maui County. In addition, a moderate to large northwest swell will build slowly into tonight, and bump combined seas up for exposed waters. Another SCA will likely be issued for tonight through Friday to account for these rough seas.

The current moderate, medium period, west-northwest swell (300-320 degree) has held steady, as noted on the Waimea Bay buoy. A reinforcing, slightly larger and slightly longer period, northwest swell (320-330) is forecast to arrive, then peak tonight into early Friday, then ease into the weekend. This second pulse may bump surf up just enough to breach High Surf Advisory (HSA) criteria along exposed north and west facing beaches during its peak. The residual small to moderate northwest swell is expected to veer to the north-northwest through the remainder of the weekend into early next week, and bring below average surf for December for north and west facing shores.

East shore surf will remain small due to weak winds, then become larger and choppier through Friday, as trade winds increase. Expect minimal background energy for south facing shores through much of the week.

Peak monthly tides combined with water levels that are running higher than predicted could lead to minor flooding along the shoreline and in low-lying coastal areas. Coastal flooding is possible around the daily peak tide, which will be during the early morning hours. This could also magnify effects of the expected high surf on coastal areas along north and west facing shores around the same time frame.

Interesting:  Student Expands Research on Microplastics in Hawaiian Waters

After graduating from Kalaheo High School, Hope Kanoa knew she wanted to focus on Hawaii’s water resources while attending the University of Hawaii at M?noa. She found a fitting option in the School of Ocean and Earth Science and Technology (SOEST), which offers a Bachelor of Arts in Environmental Earth Science.

As an undergraduate student, Kanoa conducted a research project with Xiaolong (Leo) Geng, assistant professor in the SOEST Department of Earth Sciences, to measure the concentration of microplastic in coastal environments around Oahu. After working on this project together, Geng extended an invitation for Kanoa to join his research group as a master’s student.

“Its incredible to see how connected different reservoirs of water are in Hawaii,” Kanoa said. “I’m very interested in addressing the challenge of modeling how this contaminant is transported on and in our islands.”

“Hope has demonstrated an exceptional ability to work across disciplines, connecting fieldwork, laboratory analysis, and environmental science outreach,” Geng shared. “She is never afraid to try new approaches, and her willingness to step outside her comfort zone has been a defining strength in her growth as a researcher.”
