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 Thursday evening:  A surface ridge building north of the islands will allow moderate to locally breezy trade winds to return to the islands. Rainfall will be limited into Saturday due to an upper level ridge over the islands. However 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 Thursday evening: A low pressure system east-northeast of the islands, combined with low north-northwest of the islands, are helping to disrupt the trade wind flow. However the low to the east-northeast will continue to weaken as it moves to the east away from the islands. The low to the north-northwest will lift to the north.

As this happens, the ridge to the north will strengthen, and moderate to locally breezy trades will filter back over the islands into Friday. The models agree on mid level ridging over the region, which will help to maintain a stable airmass, limiting rainfall totals over the next few days.

The models are in good agreement that moisture from the aforementioned low will get caught up in the trade wind flow over the weekend, and make its way into the islands. This will help us return to a more typical trade wind weather pattern, with some heavier showers over the windward and mountain areas, along with the clouds and showers that form over the Kona slopes during the afternoon Sunday into early next week.

Marine Environmental Conditions…as of Thursday: Trade winds will be making a come back in response to an upper ridge, slowly expanding in from west-northwest of the islands. The associated surface high far northwest of the offshore waters will travel east, passing 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 over the islands, to maintain moderate to locally fresh trade wind magnitudes the next several days.

Trades will persist through the weekend as another high passes north of the state. Brief periods of locally strong winds will be possible this weekend across the windier channels and bays surrounding Maui County and Big Island.

A small, short to medium period northwest swell that peaked yesterday, will gradually level out the next few days. A pair of North Pacific gale lows will send a series of small north to northwest swells down into the local waters Friday night through the first half of next week. These swells will maintain waist to head high surf along north-facing shores into next week. An overlapping small, short to medium period north northeast swell that peaked yesterday afternoon, introduced advisory level surf along many northeast to eastern exposures, as well as elevating surf to above average heights along select Maui and Big Island western shores. This swell has leveled out and fallen below levels that will not produce advisory level surf.  An enhanced northeast fetch in the proximity of a vicinity weak low northeast of the islands will push in a secondary swell Friday.

Moderate to fresh trades will also support near seasonal average east-facing shore wind wave surf. Small background energy from the west will continue to linger the next few days and fade out this weekend. A small southwest bump from Tasman Sea gale energy that passed across American Samoa`s 51209 buoy yesterday is expected to arrive this weekend. No significant south swells are 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.
