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.

821am, yet another similar day to the last several here on the coast. The NW prevailing westerlies start up slow during the morning hours, and then kick up their heels during the afternoon, before calming down at night. We just got back from a 1.5 mile walk down to the ocean and back up here again. There were so many Pelicans soaring along in the breeze, we stopped and watched probably 50 or more in a disjointed line.

242pm Hawaii time, just back from another fairly long walk, not down to the cliffs but rather just walking around looking at the very cool Sea Ranch houses. As it’s early evening here in northern California, it’s very breezy looking out at the ocean, with a million white caps chalking up the surface.

652pm Hawaii time, it’s clear and chilly as I get ready to bed down, with the temperature 43.3 degrees.

Hawaii’s Broad Brush Weather Overview…as of Friday evening: Trades will rule for the next week, with a gradual increase in wind speed from the middle of next week into next weekend. Otherwise, expect typical windward and mountain showers, along with Kona showers. Rainfall is expected to be rather light.

Weather Details for the Hawaiian Islands…as of Friday evening: Radar shows isolated showers in some windward areas. Satellite shows mostly cloudy skies windward and mountains, with mostly clear skies leeward. Winds were moderate, averaging 10-20 mph with gusts 20 to 25 mph in the usual spots that get breezy in the afternoon during trades.

A basic trade wind pattern will be with us for the next week. Moderate wind speeds will see a gradual increase beginning in the middle of next week. A slight increase in showers is expected Monday and Tuesday, as an area of increased low level moisture moves in from the northeast.

Upper level ridging mainly to our northwest with upper level troughing to our northeast, will keep us with light NW flow aloft for most of the next 7-days. Of note, the GFS model continues to show the possibility of a weak upper level trough moving southeast over the area Tuesday into Tuesday night, but this is not the favored solution at this time. If it were to occur, we would see some stronger showers Tuesday into Wednesday, due to instability from colder air aloft.

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 pressure gradient across the islands to maintain moderate to locally fresh trade winds for the next several days 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 tonight 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, short period reinforcing swell into the waters late tonight into tomorrow. Otherwise, average surf is expected along eastern exposures into next week due to the lack of any strong trade wind activity over and upstream of the state.

Small background energy from the west will continues to linger the next few days and will fade out this weekend. A small southwest bump from the Tasman Sea that passed across the American Samoa 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.
