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 Weather Narrative ~~~

 

Glenn’s Aloha Friday comments:  I’m home here in upper Kula, Maui, Hawaii.

It’s mostly clear here in Maui County early this morning before sunrise, with a few partly cloudy areas locally. My low temperature here at my place was a chilly 48 degrees….the coolest since I arrived back home from my extended one month working vacation in northern California.

Mid-day, and the mostly sunny weather here in Maui County prevails. It’s a beautiful day in fact, with the cooling trade wind breezes keeping the warmth of the day feeling manageable so far.

Weather Wit of the day:  Sign of Spring – “KEEP OFF THE GRASS”

 

Hawaii’s Broad Brush Weather Overview:  High pressure north of the islands will keep breezy trade winds in place. Clouds and showers will favor windward and mountain areas, particularly at night and during the early morning hours. A few showers will occasionally reach leeward communities, due to the strength of the trades, and some leeward shower development is expected each afternoon on the Big Island.

Hawaii’s Weather Details:  High pressure north of the islands continues to produce breezy easterly trade winds across the state. Satellite imagery shows partly cloudy skies across the region, with the typical distribution of clouds over most windward areas and the Kona slopes of the Big Island. Radar imagery also shows generally dry conditions with isolated showers embedded in the trade wind flow. Kauai remains an exception to our normal trade wind conditions, with mostly cloudy skies and scattered showers moving across the island, as an area of enhanced moisture lingers.

Models show high pressure shifting eastward tonight then northeastward on Saturday. This will maintain our breezy trade wind pattern through early next week. Trade may ease slightly during the middle to latter part of next week, as a cold front passes buy north of the state. Otherwise, expect fairly typical trade wind weather, with clouds and showers favoring windward areas, particularly at night and during the early morning hours. Due to the breezy trades a few of these showers will occasionally spill over into leeward areas. Will also see some afternoon shower development over the Kona slopes of the Big Island.

Hawaii’s Marine Environment:  Fresh to strong easterly trades will persist through early next week, as a surface ridge remains anchored north of the islands. A Small Craft Advisory will persist each day for the typical windier waters and channels around Maui County, the Big Island, and Kauai. The advisory may need to be expanded to Maui County windward waters and the Kaiwi Channel over the weekend.

Surf along south-facing shores will trend up above average this weekend, as a long-period south-southwest swell arrives. Forerunners will begin filling, with the surf peaking late Saturday through Sunday. This swell peaked above guidance at the American Samoan buoy Tuesday night into Wednesday, which will translate to a peak locally late Saturday into Sunday, likely driving surf to the advisory level. A gradual downward trend will follow early next week.

Surf along east-facing shores will remain rough and choppy, with heights hovering around average each day.

Surf along exposed north-facing shores will remain small through the weekend, with mainly background short-period north-northeast energy continuing. A long-period northwest swell arriving late Sunday, will lead to the surf picking back up to near average levels as it peaks Monday. Expect this trend to remain steady Tuesday through mid-week, as another medium-period pulse out of the same direction arrives Tuesday night. Expect a downward trend through the second half of next week.

Interesting:  On-Again, Off-Again at Kilauea

Since it re-awoke in December 2024, Hawaii’s K?lauea volcano has been on a short fuse. It began erupting on December 23 from vents along the southwest margin of Halemaumau Crater, located within its summit caldera. Since then, observations have shown episodes of lava fountaining lasting several hours to over a week with little respite in between.

The nineteenth such episode was in progress on the night of May 1, 2025, when the Landsat 9 satellite passed over the Island of Hawaii. The image above shows shortwave and near-infrared data, acquired with the satellite’s OLI-2 (Operational Land Imager-2) around 10:30 p.m. local time (08:30 Universal Time on May 2), revealing the heat emanating from lava in the summit crater. That information is layered over a composite of daytime Landsat images and a digital terrain model.

The fountaining episode began with low-level activity around noon local time on May 1, according to the U.S. Geological Survey Hawaiian Volcano Observatory (HVO). Around 9:30 p.m., about one hour before the heat signatures above were captured, continuous lava fountaining began, with molten rock reaching heights up to 300 feet. This activity subsided by 5:20 a.m. the next day.

Tiltmeters at Kilauea’s summit and East Rift Zone have measured cycles of inflation and deflation coinciding with each episode of the months-long eruption. Data show the ground swelling slowly while magma builds up beneath the surface and quickly reversing course when it erupts.
