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 easterly trade winds will persist, then ease into the light to moderate range Thursday through Saturday. Clouds and showers will favor windward and mountain areas, with a period of increased shower activity possible Wednesday night into Thursday, as a band of moisture moves through the islands. A few afternoon clouds and showers may develop over interior and leeward areas Thursday through Saturday where localized sea breezes form. Trade winds are expected to strengthen again late this weekend and into early next week.

Weather Details for the Hawaiian Islands…as of Tuesday evening: Short-range guidance remains in good agreement and depicts breezy easterly trade winds persisting through mid-week, as a strong subtropical ridge remains anchored north of the state. A band of moisture approaching the Big Island, combined with an elevated trade wind inversion near 10,000 feet and a weak upper-level trough, is expected to bring increased shower activity to windward portions of the Big Island and Maui later tonight through Wednesday morning. Guidance indicates a modest increase in low- level moisture during this period, with precipitable water values climbing above climatological norms to over 1.5 inches. This moisture may linger through Thursday morning, supporting enhanced rainfall chances across windward areas, potentially expanding to all windward sections of the island chain by Wednesday night.

The surface ridge north of the islands is forecast to weaken Thursday through Saturday, allowing trade winds to ease into the light to moderate range. At the same time, a drier and more stable air mass is expected to move into the area. As a result, shower activity should become more limited, with passing showers favoring windward and mountain areas during the overnight and early morning hours. Localized sea breezes will develop each afternoon, leading to a few clouds and showers over interior and leeward areas, particularly from Thursday through Saturday.

By late in the weekend and into early next week, a strengthening surface ridge north of the state, should support a return to a more typical breezy trade wind pattern.

Marine Environmental Conditions…as of Tuesday evening: Surface ridge north of the area will hold through Wednesday, then weaken Thursday through Saturday as a front passes far north of the state. Moderate to locally fresh trades will persist through Wednesday before easing to light to moderate category Thursday through Saturday. Fresh to locally strong easterly trades will return Sunday through early next week.

A series of southern hemisphere swells will continue through the week with the larger south swell of the week due to arrive this weekend. Currently, a small, medium-period south swell is overlapping a fading swell, producing 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 passed within our swell window around New Zealand earlier this week is expected to gradually fill in locally through the weekend. Wave models have this swell peaking Sunday into Monday that could drive surf heights to near the warning level. This swell will coincide with the peak monthly tides and will likely lead to significant wave runup and minor coastal flooding during the first half of next week, particularly during the peak daily high tide cycles.

A small west-northwest swell will hold Wednesday and fade Thursday. East shore surf will slowly decline below seasonal averages Wednesday through the rest of the week as trades 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.
