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: Breezy to locally windy trade will continue to push deep tropical moisture over the state tonight. Moderate to locally heavy rain remains possible along windward and mountain areas of Maui County and the Big Island. Heavy rain chances diminish late tonight, but breezy and showery trades will persist through Thursday.

Mid level drying will limit clouds and showers Friday into early next week. Easing trade winds over the weekend could allow for more of a hybrid land/sea breeze pattern over the weekend. Drier moderate trades should return Sunday.

Hawaii’s Weather Details: Satellite imagery continues to show thick mid and high clouds streaming over the eastern end of the state. Radar imagery also shows scattered moderate showers over mainly windward and mountain areas of all islands, with locally heavy showers moving into windward areas of Molokai, Maui, and the Big Island. Rainfall totals the last 6 to 12 hours across these areas have ranged from 0.25 inches on the low end to over 2 inches at Kulaimano on the Big Island and West Wailuaiki on Maui.

High resolution guidance continues to show this moisture band being pushed westward overnight by the trades. The main chance of locally heavy rainfall remains along windward and mountain areas of Maui County and the Big Island as precitable moisture levels remain close to 2 inches, with the threat diminishing overnight, as the air mass starts to stabilize and dry out. Some of these showers may continue to produce nuisance flooding tonight, but overall threat is minimal. As for the rest of the state, scattered light to moderate showers will remain focused along the windward and mountain areas under breezy trades.

The Big Island summits remained above freezing, with minimal rain accumulations. However, guidance continues to show temperatures falling to near or below freezing tonight as the moist air mass lingers over the area. Therefore, any precipitation that falls across the summits tonight will be a wintry mix of rain and snow showers, with a slight chance of light freezing rain possible. The current Winter Weather Advisory remains in effect until noon on Thursday. Conditions should quickly clear by late Thursday morning, as temperatures climb above freezing.

The strong surface high passing north will maintain breezy trade winds Thursday. Guidance continues to show a band of low level clouds and showers moving across the area on Thursday, keeping a rather cloudy and wet trade wind pattern in place.

Trade winds are expected to ease Friday into the weekend, as a cold front approaches the state from the far northwest. Mid level drying should limit clouds and showers. A few high clouds may remain as an upper level trough passes north of the state Friday.

A hybrid trade wind and sea breeze pattern could develop Saturday as winds relax, allowing for clouds and showers to develop along leeward and interior areas, and low level moisture from the dissipating front moves over the state. However, cloud heights and showers will continue to be limited due to dry mid levels. The greatest chance of showers will be around Big Island, where lingering moisture will be the deepest.

Drier and more stable conditions will fill in Sunday into early next week, as mid to upper level ridging builds over the state and moderate trades return.

Fire weather:  Critical fire weather conditions are not expected through the forecast period. Periods of heavy rain remain possible over Maui County and the Big Island. Gusty trades continue into Thursday, with winds ease below critical thresholds thereafter. Lingering moisture will keep relative humidities above critical thresholds.

Hawaii’s Marine Environment: Moderate trade winds will increase. The weakening front to the north is not expected to push much farther east, and northeast winds are already increasing, as the strong surface high behind the front is starting to exert influence. As the front dissipates and the surface high moves north of the state, expect trade winds to ramp up, eventually reaching near gale strength in the Alenuihaha Channel.

A Small Craft Advisory (SCA) is in effect for the typical windy waters around the Big Island and Maui and expands to cover all waters through Thursday as trades rapidly build. The high will be pushed to the east by a North Pacific front late Thursday and Friday, leading to a gradual decline in the trades. Trades may decline further this weekend as the front passes north of the islands.

A northwest swell is moving in and will gradually increase surf along exposed north and west shores from Kauai to Maui. A High Surf Advisory may be needed as the swell shifts out of the north-northwest and continues to build. The northwest swell will be accompanied by a small to moderate north swell aimed primarily west of Kauai, while building trades produce increased wind waves.

The combined seas from all of these sources will contribute to the need for the SCA. The north-northwest swell will gradually decline Thursday and Friday, with another northwest swell pushing surf back near the advisory level Saturday.

East shore surf will be on the rise into Thursday, primarily from increased short period trade wind swell, though the western end of the island chain could also experience a brief north (350-010 degrees) swell. As mentioned above, this north swell will be primarily aimed west of Kauai, but some wrapping energy could push east shores of Kauai near the High Surf Advisory level. The north swell will rapidly fade on Thursday, when peaking trade wind swell will produce surf just below the advisory level on east shores of all islands. East shore surf will decline through the weekend, as trades weaken over and upstream of the islands.

For south shores, tiny background south swell energy will persist.

Interesting: Weather Behind Past Heat Waves Could Return Far Deadlier

Weather patterns that produced five severe heat waves in Europe over the past 30 years could kill thousands more people if repeated in today’s hotter global climate, a new study finds. Rapid acceleration of efforts to adapt to greater extremes could save lives.

The weather patterns that produced some of Europe’s most extreme heat waves over the past three decades could prove far more lethal if they strike in today’s hotter climate, pushing weekly deaths toward levels seen during the COVID pandemic, according to a November 18 study in Nature Climate Change.

“We showed that if these same weather systems were to occur after we’ve trapped a lot more heat in the atmosphere with greenhouse gases, the intensity of the heat waves gets stronger and the death toll rises,” said lead study author Christopher Callahan, who completed the research as a Stanford Doerr School of Sustainability postdoctoral scholar and recently joined the Indiana University faculty.

Global average temperatures in recent years have approached 1.5 degrees Celsius above pre-industrial levels and about 0.7 degrees above the 2003 average, when a heat wave killed more than 20,000 people across Europe. This year, 2025, researchers estimated thousands of people may have lost their lives because of extreme heat during the fourth-hottest summer in European history.
