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 Monday 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 83%

450pm, hot or at least very warm summer-like day here on Maui…I have a low 60% relative humidity here at my place in Kula. I had a great time playing Pickleball this morning in Makawao!


>>> Highest Temperature Monday, June 8, 2026 – 109 at Rio Grande Village, TX
>>> Lowest Temperature Monday, June 8, 2026 – 21 degrees near White Sulphur Springs, MT

Hawaii’s Broad Brush Weather Overview…as of Monday evening: Breezy trades will gradually weaken to moderate speeds by the latter half of the week. Periodic showers will filter in on the trade wind flow, mainly focusing over windward and mountain areas through mid-week. By late this week, the wind flow may become light enough to support land and sea breeze development, and showers may increase in some leeward areas.

Weather Details for the Hawaiian Islands…as of Monday evening: Satellite and radar show a band of showery low clouds moving east to west across Hawaii with the breezy trade winds. Showers have been anchoring over windward slopes of Kauai and Oahu, and Maui County to lesser extent. Expect another 12-24 hours of the passing showers across windward sides of the smaller islands, before Hawaii sees the end of this band.

A 1028 millibar high is centered far north-northeast of Hawaii drifting slowly northeastward. Soundings show an inversion over the state around 7,000 feet with precipitable water around 1.2 inches. The stable conditions will limit rainfall amounts, with most occurring windward due to terrain effects, and occurring during the nighttime and early morning hours.

An approaching cold front will begin to influence the wind flow over the islands as early as Wednesday. Winds will weaken to moderate on Wednesday, then gentle by late Thursday into the weekend, as the front moves closer and the subtropical high drifts away to the northeast. This in turn will allow for a hybrid pattern of weak trade winds combined with sea and land breezes Thursday and Friday, with all land/sea breezes Saturday. Daytime sea breezes will result in interior clouds and showers, while nighttime land breezes clear out the cloud cover across the islands. Models show the front stalling and dissipating well northwest of Hawaii Sunday, with trades expected to strengthen again early next week.

Marine Environmental Conditions…as of Monday evening: Surface high pressure will remain anchored far northeast of the islands through early this week. A Small Craft Advisory (SCA), remains in effect for the typical windy waters around Maui and the Big Island until 6pm tonight. By mid-week, a ridge north of the islands associated with the high will be weakened and depressed southward, resulting in even weaker trades. As the ridge shifts further south, it will eventually end up near the Hawaiian Islands by Friday or Saturday, which will bring light and variable winds across the area towards the end of the week.

Small long-period south swell continue to fill in this morning. Energy from this swell is expected to peak later today into tomorrow, and bump up surf to slightly higher than the June averages, but still below advisory criteria. This swell is expected to fade through mid-week. A smaller pulse of south-southwest swell is due late Thursday and Friday, and a more significant south- southwest swell is on track to arrive by the weekend, likely bringing advisory level surf by late Sunday along south facing shores.

The combination of a large south-southwest swell coinciding with the peak monthly tides will lead to significant wave runup across areas of the shore that typically remain dry during the afternoon high tide cycle from June 14th through June 16th. Coastal flooding is also expected across low-lying coastal roadways, docks, boat ramps and other coastal infrastructure.

Small background energy from the west-northwest is possible over the next several days, from a former Typhoon in the West Pacific last week.

Rough surf along east-facing shores will remain around seasonal averages, slowly declining through mid-week as the trades ease. Surf will drop well below seasonal levels along east facing shores by the end of the week.

Cristina is moving slowly toward the north near 2 mph, and a slow meandering motion is forecast for the next day or so followed by a slow northwestward motion. On the forecast track, Cristina should move near or along the coast of Nicaragua, Honduras and El Salvador over the next couple of days.

Maximum sustained winds are near 45 mph with higher gusts. Little change is strength is forecast over the next day or two.

Dan Gillikin surveyed the view from his front window and didn’t like what he saw.

The Aniak River, which runs alongside his house, was a jumble of car-sized chunks of ice. Breakup on the nearby Kuskokwim River had pushed a frozen snarl down the Aniak, making it impassable.

“I’m basically looking at Armageddon right now,” he said, describing the scene by phone in early May.

Before Gillikin bought an old homestead at the mouth of the Aniak River about 15 years ago, he wondered how isolated the property would become each spring from the nearby village of Aniak. Locals said he could count on being stranded for 3-5 days while the river transitioned from ice to water.
