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 Aloha Friday comments:  I’m here in a wonderful vacation rental at The Sea Ranch, Sonoma County, California with my friend Bob, continuing on in my working vacation.

 

>>> Highest Temperature Thursday, April 23, 2026 – 102 degrees at Grande Village, TX
>>> Lowest Temperature Friday, April 24, 2026 – 8 degrees near Neihart, MT

 

Hawaii’s Broad Brush Weather Overview…as of Friday morning:  A ridge to the north will maintain moderate to locally breezy trade winds into the weekend. An upper level ridge overhead will help to limit rainfall totals into Saturday. Low level moisture riding in on the trades will bring more typical windward and mountain showers by the end of the weekend into early next week.

Weather Details for the Hawaiian Islands…as of Friday morning: A ridge north of the islands will allow moderate to locally breezy trade winds to spread across the islands. The overnight soundings show slightly higher precipitable water values near the Big Island than near Kauai. Satellite shows some additional clouds forming near the Big Island in the pre-dawn hours. Rainfall totals are expected to remain low into tomorrow with mid level ridging in place.

Moisture associated with a trough of low pressure to the far northeast of the island chain, will get caught up in the trade wind flow this weekend. This will result in an increase in shower activity to more typical trade wind showers for the first part of the upcoming new week ahead. By mid-week, a new cold front by passing north of the state could once again disrupt the trade wind flow.

Marine Environmental Conditions…as of Friday: Trade winds have returned in response to an upper ridge slowly expanding in west northwest of the islands. The associated surface high far northwest of the offshore waters will travel east, pass north of the local waters and be northeast of the area by early next week. This will produce a tight enough Central Pacific pressure gradient across the islands to maintain generally moderate to locally fresh trade wind magnitudes the next several days. Moderate trades will persist into next week as another high passes north of the state.

A pair of northern gale lows will send a series of small size north northwest swells (320-330 degree) into the local waters from Friday night into the first half of next week. These swells should help maintain near average surf along north-facing shores. A deepening weekend storm low developing near the Aleutian Islands may send a slightly larger northwest swell towards the islands by mid next week.

The current short to medium period north northeast swell (30 degrees) will continue to decline this evening. A small fetch of fresh northeast winds associated with a very weak low northeast of the state could provide a short-lived reinforcing short period swell into the water late Friday into Saturday. Otherwise, below average surf is expected along eastern exposures into next week due to the lack of any significantly strong trade wind activity over or upstream of the state.

Small background energy from the west will continue to linger the next few days and fade out this weekend. A small southwest bump from the Tasman Sea that passed across American Samoa`s 51209 buoy Wednesday is expected to arrive early tomorrow. No significant south swell is expected through the first half of next week.

Interesting:  Alaska Climate Report: March 2026 Saw Dangerous Weather

March brought a series of dangerous and disruptive weather events across Alaska. Severe cold combined with powerful storms to affect communities statewide, according to the monthly summary from the Alaska Climate Research Center.

The Alaska Climate Research Center, which is a part of the University of Alaska Fairbanks Geophysical Institute, published its March summary earlier this month.

March began with blizzard conditions, deep snow and extreme temperatures stranding residents and travelers.

Residents of Denali Borough became isolated, and a storm trapped more than 150 people at a basketball tournament in Kaktovik.

New hazards emerged as the month progressed. A river ice rescue occurred near Fairbanks when a person broke through thinning ice on the Chena River. A fatal avalanche in the Chugach Mountains east of Anchorage highlighted ongoing snowpack instability.
