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.

Glenn’s Monday comments:  I’m at home here in upper Kula, Maui, Hawaii

It was clear with some clouds along the windward sides this morning here in Maui County, with a low temperature at my place a chilly 49 degrees.


>>> Highest Temperature Sunday, May 10, 2026 – 114 degrees near Tecopa, CA
>>> Lowest Temperature Monday, May 11, 2026 – 13 degrees near Kipling, MI

 

Hawaii’s Broad Brush Weather Overview…as of Monday morning: Trade winds will continue through the week. Showers should favor windward and mountain areas, most frequently at night and during the early morning hours. Overall, the next week will be drier for most folks than this past week.

Weather Details for the Hawaiian Islands…as of Monday morning: Radar shows some scattered showers ongoing across the state. In addition, satellite imagery shows thin high clouds continuing to stream over the region from the west-southwest, although gradually shifting away, with lower level clouds moving on with the trade winds.

At upper levels, a ridge of high pressure north of the island chain, spreads across much of the Pacific south of 35 degrees north latitude, which will dominate our weather for the upcoming week. A minor weakness in the ridge may develop late in the week, but guidance is in relatively good agreement that it won`t be enough to weaken the associated surface ridge.

We will experience a typical springtime trade wind weather pattern, with passing showers mainly along the windward and mountain areas, with some limited spillover to leeward areas locally. The trade winds look to be moderate to breezy, strong enough to be concerning for boaters, but probably not strong enough for wind advisories over our land areas.

Marine Environmental Conditions…as of Monday morning: High pressure remains in place north of the Hawaiian Islands this week, maintaining fresh to locally strong trades continuing into next weekend. The Small Craft Advisory remains in effect.

A small, medium period, NW swell maintains small surf along north and west shores. Another small, long period, NW swell arrives Wednesday afternoon and peaks early Thursday.

Two additional small, long period, south swells arrive today and again on Thursday, keeping surf heights along south facing shores above flat levels. Surf along east shores remains below normal in the near term, with increasing surf peaking by Wednesday as our trade winds strengthen.

Interesting:  Lancaster Environment Lecture Examines Why a Healthy Ocean Matters to us All

A look at how the ocean is changing faster than at any point in human history will be the topic of a Public Lecture organized by Litfest and Lancaster University’s Faculty of Humanities, Arts and Social Sciences.

The annual Lancaster Environment Lecture, entitled The Future of the World’s Ocean, will be delivered by marine biologist Dr Helen Scales in the Faraday Lecture Theater at Lancaster University at 7pm on Tuesday, 12 May, 2026.

Drawing on her book ‘What the Wild Sea Can Be’, Dr Scales’ will show how a healthy ocean matters to us all, from the food we eat, to the weather we experience and the air we breathe.
