Hawaii’s Mountains – Here’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii. Here’s the webcam for the (~10,023 feet high) Haleakala Crater 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 Tuesday comments:  I’m at home here in upper Kula, Maui, Hawaii

It’s mostly clear with some clouds along the windward sides here in Maui County, with calm winds at my place, and with a low temperature of 51 degrees and the relative humidity is 80%

1249pm, I’m just back from shopping at Mana Foods in Paia, where it was 82 degrees when I left there, and it was 71 degrees when I got back here in Kula.


>>> Highest Temperature Monday, June 8, 2026 – 109 at Rio Grande Village, TX
>>> Lowest Temperature Tuesday, June 9, 2026 – 28 degrees near Grand Lake, CO

 

Hawaii’s Broad Brush Weather Overview…as of Tuesday afternoon: Breezy trades will gradually weaken to moderate speeds Wednesday through the rest of the week, becoming relatively light this weekend. Isolated showers will continue to focus over windward and mountain areas through Wednesday. Thursday, lighter winds will support sea breezes each afternoon, increasing chances of clouds and showers over mountain and interior areas, with land breezes clearing these clouds and decreasing chances of showers overnight and early mornings.

Short Term Update: A high northeast of state will maintain moderate to breezy trades. A batch of low level clouds and showers will continue to generate scattered showers mainly along windward and mountain areas. Some clouds are building along the upslope of the Kona coast of the Big Island as afternoon seabreezes develop in this area, increasing the chance of isolated showers this afternoon.

Weather Details for the Hawaiian Islands…as of Tuesday afternoon: A high pressure system far northeast of the islands, with an associated ridge stretching west about 600 miles north of Kauai, is generating fresh trades across the area. This high will be pushed eastward over the next several days, and its associated ridge will be displaced southward, resulting in the slow decrease in local trades. A Small Craft Advisory (SCA) is in effect for the typically windy waters around Big Island and Maui until 6pm tonight. Trades should be down into the moderate to locally fresh range, and will continue to fall into the gentle to moderate category by Friday, and may hold into the weekend.

A series of southern hemisphere swells will continue through the week with the largest due to arrive this weekend. Currently, a building long-period south swell is overlapping a fading medium-period swell. The bulk of the new swell energy was aimed east of Hawaii, which still leaves some uncertainty in resulting surf heights through this evening. Expect south shore surf to be around seasonal averages today, and then slowly declining Wednesday, followed by a smaller pulse of south-southwest swell Thursday and Friday.

A much larger south-southwest swell will arrive Saturday night and Sunday. A storm just southeast of New Zealand is producing a fetch of seas in excess of 40 feet aimed at Hawaii, and there is growing confidence that south shore surf will well exceed High Surf Advisory levels during the peak Sunday into early next week, with High Surf Warning conditions possible. This swell will coincide with the peak monthly tides, and will likely lead to significant wave runup and impacts to coastal infrastructure.

A small west-northwest is possible over the next few days, while rough east shore surf slowly declines below seasonal averages.

Cristina is drifting toward the west-northwest near 1 mph. A general west-northwestward motion at a slow forward speed is expected during the next couple of days. On the forecast track, Cristina should move near or along the coasts of Nicaragua, Honduras, and El Salvador during the next couple of days. Maximum sustained winds are near 40 mph with higher gusts. Slight strengthening is possible through Wednesday, while a general weakening trend is expected Wednesday night or Thursday. Tropical-storm-force winds extend outward up to 80 miles from the center.

Interesting:  Fighting Fire with Fire

In May and June of most years, NASA satellites typically begin to detect large numbers of wildland fires throughout the Top End and Arnhem Land regions of Australia’s Northern Territory. On some days, especially in the afternoon, the blazes can resemble sizable wildfires in satellite imagery, spreading widely and producing expansive smoke plumes.

That was the case when NASA’s Aqua satellite acquired this image of smoke and fires on the afternoon of May 28, 2026. Often, however, fires burning in this area look smaller and less imposing. In the mornings just a few days earlier and later, for instance, NASA satellites detected little smoke despite observing many thermal anomalies, or hotspots, that indicated fire activity.

The pattern of burning, location, and timing are consistent with prescribed fires lit intentionally to manage the landscape. Land managers tend to light fires in the morning, and smoke builds over the course of the day. The process sometimes creates sizable plumes when there are updrafts and winds of moderate strength that carry smoke away from the fires, as happened on May 28 and again on June 2. The fires typically burn through the fire-adapted grasses, underbrush, and scattered trees in the region’s tropical savanna ecosystems.
