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 Vancouver, BC, Canada on a working vacation.

Bob and I drove up to Vancouver from Bend early yesterday morning. It was a long 10 hour drive, and we made it by late afternoon. We’ve rented a place here in Vancouver for a week, and it has a great view of the surrounding area…and is fortunately in a quiet neighborhood.

433am Hawaii time, the low temperature was 40.5 degrees with some high cirrus clouds showing up, after a totally clear day yesterday. I’m thinking that these high cirrus clouds are the front edge of a prolonged period of rainy weather…hopefully not.

 

>>> Highest Temperature Thursday, April 9, 2026 – 98 degrees at Gila Bend, AZ
>>> Lowest Temperature Friday, April 10, 2026 –  12 degrees at Aberdeen, SD

 

Hawaii’s Broad Brush Weather Overview…as of 438am Friday morning:  A low northwest of the state will swing east before lifting north today and be absorbed is a stronger, nearly stationary, low far northwest of the state. A front just west of Kauai associated with the low will move eastward pushing a broad band of showers eastward across the state through the day.

Strong southerly winds ahead of the front will shift over Oahu this morning with light westerly winds filling in behind the front. Drier and lighter winds are expected to fill in across the state Saturday, as the front pushes east of the state and weakens.

Chance of showers will increase again across the state Sunday into early next week. Land and sea breezes will dominate much of the weather pattern next week, as the low remains north of the state.

Weather Details for the Hawaiian Islands…as of 438am Friday morning: Latest satellite imagery shows a low 500 miles northwest of Kauai, with a south to north orientated cold front just west of Kauai. A broad cloud shield remains over the the state. Radar shows light to moderate showers blanketed across the state, with heavier showers building over Kauai this morning. High resolution model guidance shows the frontal band moving east across the state today shifting the chances of heavier showers across Oahu later this morning and afternoon before moving onwards to Maui County tonight. Steady light to moderate showers will continue along the southeast Big Island.

Strong southerly winds remain over Oahu which could still produce downsloping winds in areas north and downwind of steep terrain. As the front progresses towards the central island later this afternoon and evening, wind speeds will continue to trend downward. Behind the front winds will ease to light and variable speeds. Big Island summits will continue to see advisory level winds through today before tapering off this afternoon, thus the Wind Advisory remains in effect through this afternoon. The Winter Weather Advisory also remains in effect through this afternoon.

The low will become absorbed in a stronger, nearly stationary, low far northwest of the state Saturday. Remnant moisture lingering over the eastern half of the state will still produce some scattered showers, but overall flooding threat will have decreased as low to mid level drier air filters in from the west to east across the state. An upper level shortwave is expected to dip southeastward Sunday, likely supporting another active weather period across the state, that may extend through early next week.

Winds will remain light through much of next week as this larger low slowly weakens through the first half of next week, before shifting northeast during the second half of next week. Light winds and lingering moisture will allow for afternoon sea breezes building clouds and increase showers over interior areas. Land breezes will develop overnight providing some clearing. This pattern is expected to persist through much of next week, as this low keeps the island chain cut off from trade winds returning.

 

Here’s a near real-time Wind Profile of the Pacific Ocean – along with a Closer View of the islands / Here’s the latest Weather Map / Looping Surface Precipitation…through the next 8-days/


Marine Environmental Conditions: As the low pressure system to the northwest further deepens, we will likely see a few strong to severe thunderstorms capable of producing waterspouts and damaging winds over the coastal waters. Rough boating conditions are expected with elevated seas and strong to near gale force southerly winds. Strong southerly winds are expected to slowly decrease west to east.

Surf along the southern shores is slowly declining. Along north facing shores, the current northwest (320 degree) swell is slowly decreasing and should dissipate. However a smaller short-period northwest swell generated by the aforementioned low will fill in tonight through early next week. Surf along east facing shores could see an increase later this week, due to the strengthening southeasterly winds especially for southeast exposures.

Interesting: Global Warming May be a Boon for This Aggressive Prairie Plant

Climate change may reduce yields of crops like corn and soybeans, but it can also give some plants an edge.

That’s one of the takeaways of a recent study of tall goldenrod, a common wildflower that runs rampant in fields across its native range in North America and other parts of the world where it has been introduced.

Many goldenrod plants are pocked by tumorlike growths, called galls, that form when insects trick the plant into building a nursery for their larvae. New research suggests that climate change can offset some of the harmful effects of these insect squatters — effects that would otherwise help keep goldenrod plants in check.

The tuft of leaves on this goldenrod plant is caused by tiny fly that uses the plant as a nursery.
