Hawaii’s Mountains – Here’s a link to the live webcams on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii, and atop the Haleakala Crater (~10,023 feet) 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 Saturday comments:  I’m here in upper Kula, Maui, Hawaii.

I went to play pickleball in Haiku this morning, although I must have gotten there too early, as there was no one there…disappointing for me. Then I went to Mana Foods for a big shopping after being gone for a month. I had a friend over for dinner and a meditation, which was a nice experience.

Weather Wit of the day:  Two people were dining in the first restaurant on the moon. After looking around one said. “I don’t like this place-it lacks atmosphere.”

 

Hawaii’s Broad Brush Weather Overview:  A cold front stalling northwest of Kauai will weaken the trade winds slightly through Monday. Breezy trade winds return Tuesday onward, as the subtropical ridge builds in north of the island chain. Brief passing showers remain in the forecast through Sunday, shower trends increase early in the new week, especially during the overnight to early morning hours.

Hawaii’s Weather Details:  The satellite imagery shows an area of strong subsidence and stability over the eastern islands tonight. An upper level cold core low roughly 800 miles west of Kauai will slowly drift towards the state early in the new week. A cold front stalling out roughly 800 miles northwest of Kauai will slowly weaken the ridge north of the state.

Typical moderate to breezy trade wind weather will continue, with brief periods of showers for windward and mountain areas of most islands. The highest chances for showers in this weather regime will favor the overnight to early morning hours, with decreasing shower coverage during the daytime hours.

After a brief decrease in easterly trade wind speeds from Sunday to Monday, the subtropical ridge will build back in north of the island chain. This stronger ridge will increase trade wind speeds back up to breezy levels from Tuesday to Wednesday.

Shower trends will briefly increase, from Sunday night through Tuesday night, as large scale stability decreases. Remnant clouds from an old frontal cloud band drift into the islands on the trade winds from Tuesday night to Wednesday morning.

Hawaii’s Marine Environment:  Fresh to strong easterly trade winds will persist into Sunday, then ease slightly over the western end of the state late Sunday into Monday, as a weakness develops in the surface ridge due to a cold front passing by far north of the area.

The ridge is expected to restrengthen Monday night through mid-week, as strong high pressure builds eastward behind the front. Despite the brief weakening in the trades Sunday into Monday, advisory-level winds may continue over the windier marine waters around Maui County and the Big Island, with an expansion of stronger trades to additional waters possible from Tuesday through mid-week.

Surf along south-facing shores will hold steady, then begin to lower into Sunday as the current south swell starts to ease. A fresh, long-period south-southwest swell is expected to arrive by Sunday night, peaking Monday into Tuesday, with surf returning to around average. A gradual downward trend is expected from late Tuesday through mid-week.

Surf along east-facing shores will hold steady near seasonal averages through next week, due to the persistent trade winds.

Surf along north-facing shores will gradually ease this weekend as a medium-period north-northwest swell fades. A small background pulse arriving late Sunday into Monday may help keep surf from going flat. Another medium-period north-northwest swell arriving Tuesday into mid-week could bring surf back up to near average levels.

Interesting:  How ‘Parks for Bugs’ Boost Pollinators in Vancouver

As the days get longer and gardeners plan their spring planting, research from the University of British Columbia offers some good news this Earth Day: small, simple changes to urban green spaces can make a big difference for pollinators. The study, published in Ecology Letters, found that reducing lawn mowing and creating pollinator meadows – think of them as ‘parks for bugs’– significantly boosts pollinator diversity, creating healthier and more resilient ecosystems.

A buzzing success! The three-year study, conducted in collaboration with the City of Vancouver’s pollinator meadows program, surveyed pollinators in 18 urban parks across Vancouver, comparing parks where meadows were planted and mowing was restricted with parks that remained as standard turfgrass lawns.

And while the tall grass caused a small stir among some neighbors, the results were striking: parks with meadows saw an immediate increase in pollinator species, with 21 to 47 more wild bee and hoverfly species compared to parks without meadows. The increase persisted over the three-year study period, suggesting that the meadow parks also support pollinators in the long run.
