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.

Glenn’s Thursday comments:  I’m here in Corte Madera (Marin County, CA) at my friend Linda’s place

It’s cloudy with light rain early this morning…with a low temperature of 48.5 degrees.

It was a partly cloudy and rather cool day here in northern CA, with no more rain forecast through the end of my working vacation.

Hawaii’s Broad Brush Weather Overview: A breezy and somewhat wet trade wind flow will prevail into Friday morning, followed by a gradual decline in winds and shower activity later Friday. Trade winds will decline to light to moderate strength as high clouds thin during the weekend, and while showers will favor windward slopes, a few afternoons shower will be possible over leeward terrain Saturday. A stable moderate trade wind flow is expected Sunday through early next week.

Hawaii’s Weather Details: Breezy trade winds persist, and a band of shower-bearing low clouds can be observed just off the windward coasts of most islands, underneath a shroud of layered high clouds. A high is centered northeast of Hawaii, which is driving the gusty trades, while a persistent upper level trough centered just to the west and northwest, continues to send layered high clouds over the state. Shower activity has been subdued over all islands except windward Kauai, as the low level flow has dried slightly ahead of a band of moisture lingering just east of the islands.

Shower activity is expected to pick up tonight and linger into Friday morning, as the band of moisture is carried in on the gusty trade wind flow. The bulk of the rainfall will be focused on windward slopes, but periods of showers are expected over leeward areas from Kauai to Maui, as the breezy trades begin a slow decline. The nearby upper level trough will continue to send layered high clouds over the state, and a weak mid level ridge will likely be eroded as the band moves through, opening the possibility for a few briefly heavy showers tonight. A few of those showers may reach the high summits of the Big Island as rain, though there is a small possibility of some ice briefly developing late tonight.

Trade winds will decline into the light to moderate range late Friday and Saturday as shower activity decreases. A trough aloft will pick up the upper level trough that has been sitting near the islands and push it overhead on Saturday. It does not appear that it will produce a great deal of instability, but under the weakened trade wind flow, it could trigger a few afternoon showers over leeward terrain in the afternoon.

Light to moderate trade winds will hold Sunday through early next week, as upper level ridging moves overhead and produces a rather stable pattern of mainly windward showers. Trades may become disrupted during the middle of next week, but the spread in model guidance remains significant, keeping uncertainty high.

Fire weather:  Critical fire weather conditions are not expected through the week. A breezy and somewhat wet trade wind flow will keep humidity elevated into Friday, with rainfall and trade winds decreasing late Friday and Saturday. Light to moderate trade winds and rather stable conditions will prevail Sunday through early next week.

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.
