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.

Hawaii’s Broad Brush Weather Overview: Breezy to locally windy trades will persist through today, before weakening to light to locally breezy over the weekend. Expect showers to focus mainly over windward and mountain areas, with some showers spilling over to leeward locations today. 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. Drier moderate trades should return Sunday.

Hawaii’s Weather Details: Satellite imagery shows mid and high clouds streaming over the state from southwest to northeast, and a band of low level clouds moving from east to west just east of the state. Radar imagery also shows scattered light to moderate showers embedded within this band of clouds that will push west. Precipitable water imagery shows drier air behind this band clouds. In addition, the atmospheric sounds also show drier air infiltrating in the low to mid levels, that will limit showers to more light to moderate intensities today.

Overnight passes also showed that this band is on the leading edge of slightly stronger winds. Thus can expect breezy to locally windy trades to continue through today, with clouds and showers mainly focused along windward and mountain areas, some showers may still spill over to leeward areas at times. A Winter Weather Advisory remains in effect as temperatures and elevated moisture will bring period of light snow to the summits. Conditions are expected to improve shortly after sunrise and with the drying trend this advisory maybe cancelled later this morning.

A surface high far northeast of the state that is generating the breezy trade winds will begin track east and weaken tonight through the weekend, as a cold front passes north of the state. Friday trade winds will taper to more typical trade wind speeds, and the drier airmass will continue to fill in limiting clouds and showers mainly to windward and mountain locations. Mid to upper level clouds will still create partly to mostly cloudy conditions.

By Saturday a hybrid trade wind and sea breeze pattern could develop. Mid to upper level clouds will still linger across the state, as an upper level disturbances moves overhead. In addition, low low level clouds and showers from the remnant front may move over the state, increasing shower potentials. 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 Monday, as mid to upper level ridging builds over the state. Winds may veer east-southeast during the first half of next week as another front approaches the state from the northwest. Not expecting any significant weather as low to mid levels will remain dry during this time.

Fire weather:  Critical fire weather conditions are not expected through the forecast period. A wet, breezy trade wind pattern will hold with winds tapering off Friday into early next week. Lingering low level moisture will keep minimum relative humidity levels above critical thresholds. Inversion heights range from 6,000 to 7,000 feet.

Hawaii’s Marine Environment: A moderately strong high far north-northeast of the state will help maintain fresh to strong easterly trade winds. As the high drifts eastward Friday through the weekend, trades will begin to slowly trend down. If current guidance holds, the SCA could be dropped all together by Saturday.

The current moderate, medium period, northwest swell (320) has peaked, as noted on the Waimea Bay buoy observations. This swell will slowly lose energy, but should continue to keep surf elevated for north and west facing shores. Another moderate, medium period, northwest swell (310-330) is forecast to arrive Saturday into Sunday, and should once again produce surf at or near advisory levels along north and west facing shores. Looking ahead towards mid next week, a large, long period, northwest (310-330) swell is forecast to arrive and could bring advisory or even warning level surf along north and west facing shores.

East shore surf will remain elevated and rough, but is expected to decline Friday into the weekend as trades weaken over and upstream of the islands.

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.
