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 Thursday comments: I’m here at home in upper Kula, Maui, Hawaii

Good day everyone, I hope you have a great Thursday wherever you happen to be spending it.

521am, it’s a clear morning, with a low temperature of 51 degrees.

 

Hawaii’s Broad Brush Weather Overview:  Trade winds will strengthen today, then become breezy Friday through the weekend. Clouds and showers will favor typical windward slopes, with an increase in showers expected this weekend through the first half of next week, as a disturbance aloft passes overhead.

Hawaii’s Weather Details:  A stable easterly trade wind flow remains over the islands with a weak trough northwest of Kauai, and a high to the far northeast. Satellite imagery continues to show partly to mostly cloudy skies across the region, with radar showing isolated showers across mainly windward slopes.

Expect trades to strengthen today as the trough weakens further, and high pressure builds over the area, with clouds and showers favoring windward and mountain areas. With no areas of organized moisture upstream of the islands rain totals will remain limited today.

Breezy to locally windy trades look to develop over the state Friday, then continue through the weekend as high pressure settles to the northeast. This will drive an increase in clouds and showers over windward, with a few showers drifting into leeward areas due to the stronger winds. Expect the strongest winds over the windier areas of Maui County and the Big Island.

Models continue to show an upper level low stalling to the west of Kauai over the weekend, then slowly moving across the state early next week. As the low moves across the state expect a boost in to our trade wind showers, with a few brief downpours possible through the first half of next week.

Details are still uncertain, but windward areas could become quite showery through early next week, especially across the western end of the state where the best instability exists. Guidance also continues to hint at an outside chance for some isolated thunderstorms during this time period.

Expect a return to a more typical moderate to breezy trade wind pattern by Wednesday, as the upper low moves away from the state.

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

Marine Environmental Details:  Moderate to locally strong easterly trades will gradually return as a high pressure far northeast of the state shifts south, and a weak trough northwest of the state moves farther west. Trades will strengthen to fresh to locally strong Friday and persist into early next week, as another high builds north of the state and remains nearly stationary.

The Small Craft Advisory (SCA) for typical windy waters around Maui and the Big Island has been extended through Monday. Maalaea Bay has also been added to the SCA as well as the wind direction becomes for favorable for this area and winds strengthen. Additional waters will likely be added Friday, as trade winds continue to strengthen and expand in coverage.

Tiny surf will persist along north and west facing shores through Friday. A small northwest swell is expected to fill in Friday night and peak Saturday, bringing small surf along north and west facing shores. Another small northwest swell will fill in late Sunday, maintaining small surf along north and west facing shores into early next week.

Small background south swells will continue into Saturday, providing tiny surf for south facing shores. A small south swell may arrive Sunday providing a boost in surf along south facing shores into early next week. Surf along east facing shores will gradually become rough and choppy through the weekend as trades return.

Interesting: U.S. Saw Drop in Wind Power Last Year, Despite New Turbines

For the first time since the 1990s, U.S. wind generation dropped last year, according to government figures. The slump is the result of weak winds, and it comes despite the continued buildout of wind turbines nationally.

In 2023, the total amount of power U.S. turbines could theoretically produce reached a record high, according to an analysis from the Energy Information Administration. But wind plants generally run well below their maximum, and last year that was especially true.

Facing doldrums, wind turbines operated at 33.5 percent of their capacity, down from an all-time high of 35.9 percent the year prior. The result was a small drop in the total amount of power produced.

Experts say the drop is due to El Nino, the warmer phase of the Pacific Ocean, which weakened wind speeds across much of the country, but particularly in the Midwest, where turbines are abundant. Wind speeds are expected to pick up again this year as the cooler La Nina phase sets in.
