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.

558pm, very sunny and warm, with no rain in sight here on Maui, at least from my perspective here at home in upper Kula.

Hawaii’s Broad Brush Weather Overview…as of Tuesday evening: Breezy trades will gradually weaken to moderate speeds Wednesday through the rest of the week, becoming relatively light this weekend. Scattered 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.

Weather Details for the Hawaiian Islands…as of Tuesday evening: A high northeast of state will maintain breezy trades through Wednesday. A batch of low level clouds and showers will continue to generate isolated showers mainly along windward and mountain areas. Clouds and moderate showers have developed along the upslope of the kona coast of the Big Island, as sea breezes have kicked in. Expect clouds and showers to clear along shortly after sunset, as land breezes develop along the kona slopes of the Big Island.

Near term model analysis shows the high northeast of the state gradually shifting further northeast tonight and Wednesday, allowing winds to ease a notch compared to today. Expect clouds and showers to focus mainly along the windward and mountain areas tonight and early Wednesday morning, with a drying trend starting Wednesday afternoon. This will be due to a combination of weak lift from easing trade winds and drier air filtering in from the east.

The high will begin to weaken Thursday through the weekend, as a weak cold front approaches the state from the northwest. Breezy trade winds will weaken to light to gentle speeds Friday and hold through the weekend, in response to the lack of a pressure gradient across the state. The lighter winds will allow for sea breezes to develop each afternoon beginning Thursday, that could slightly increase chances clouds and showers developing upslope of mountain terrain and over interior areas, however available moisture will be limited.

Late this coming weekend the surface high pressure system located far northeast of the island chain, will build back as the front dissipates to the north. Breezy northeast trade winds will gradually build back Sunday into early next week. A more typical breezy trade wind pattern will return next week, as clouds and showers become more focused along windward and mountain areas.

Marine Environmental Conditions…as of Tuesday afternoon: A high pressure far northeast of the islands will shift further northeast tonight and Wednesday before gradually weakening through the weekend as a weak front passes far north of the state. A Small Craft Advisory for windier waters around Maui County and the Big Island has been cancelled as winds have weakened just below advisory levels and the winds. Moderate to locally fresh trades will hold through Wednesday before easing to light 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 south swell due to arrive this weekend. Currently, a small, long- period south swell is overlapping a fading medium- period swell and is producing inconsistent near seasonal average surf along south facing shores. These swells will slowly decline Wednesday into Thursday. A smaller pulse of south- southwest swells will fill in late Thursday into Friday keeping surf elevated along south facing shores.

Long period energy from a storm that formed just east of New Zealand Tuesday is now filling in at the American Samoa buoy at 20 seconds. This swell is expected to gradually fill in locally late Friday into Saturday. Wave models have this swell peaking Sunday into Monday that could produce High Surf Warning conditions. This swell will coincide with the peak monthly tides and will likely lead to significant wave runup and impacts to coastal infrastructure during the first half of next week.

A small west-northwest swell will hold into Wednesday and fade Thursday. East shore surf will slowly decline below seasonal average Wednesday through the rest of the week as trade winds locally and upstream ease.

Tropical Cyclone 03E (Cristina) 

CRISTINA CONTINUES TO MEANDER OFFSHORE…HEAVY RAINS EXPECTED TO CONTINUE OVER PORTIONS OF CENTRAL AMERICA DURING THE NEXT COUPLE OF DAYS

According to the NHC advisory number 8…Cristina is located about 130 west of Managua, Nicaragua

Cristina is moving slowly toward the west near 2 mph. A turn to the west-northwest and northwest is forecast over the next couple of days. On the forecast track, Cristina should move near or along the coasts of Nicaragua, Honduras, and El Salvador through midweek. Maximum sustained winds remain near 40 mph with higher gusts. Slight strengthening is possible through Wednesday, with weakening expected Wednesday night or Thursday after Cristina moves inland. 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.
