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 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 48.5 degrees.

255pm, it’s mostly sunny to partly cloudy here on Maui, with my wind chimes letting me know that the trade winds are back.


>>> Highest Temperature Monday, May 11, 2026 – 114 degrees Death Valley, CA
>>> Lowest Temperature Monday, May 11, 2026 – 13 degrees near Kipling, MI

 

Hawaii’s Broad Brush Weather Overview…as of Monday afternoon:  Breezy trade winds will continue through most of the week. Showers will favor windward and mountain areas, most frequently at night and during the early morning hours. Late this week into the weekend, an upper-level disturbance may bring a slight increase in trade wind shower coverage.

Weather Details for the Hawaiian Islands…as of Monday afternoon: Radar and satellite imagery show low-level clouds and scattered showers moving into windward and mountain areas, on the east-northeasterly trade wind flow. A weak surface trough remains near Kauai, allowing for a higher concentration of low-level clouds and showers to move over this end of the state.

This boundary is expected to gradually lift north and dissipate by mid-week. Otherwise, high pressure ridging at the surface and aloft will maintain stable, breezy trade wind weather across the state through at least Thursday, with isolated to scattered showers favoring windward and mountain areas.

Heading into the weekend, model guidance suggests that a mid- to upper-level low will move over the region, bringing cooler temperatures aloft and increasing instability. At the same time, precipitable water values are expected to climb to 1.5 to almost 2 inches over the eastern end of the state. However, with ridging expected to continue to dominate at the surface, this setup will likely only amount to an increase in trade wind shower activity through the weekend.

Marine Environmental Conditions…as of Monday afternoon: High pressure remains in place north of the Hawaiian Islands this week in maintenance of fresh to locally strong trades continuing into next weekend. The Small Craft Advisory has been extended through tomorrow.

Small short period NW swell has been slow to arrive this afternoon but should bring elevated surf this evening into tonight for favored exposures. A long period NW swell arrives late Wednesday and peaks Wed night into early Thurs.

A small long period S swell has likewise been slow to arrive with long period energy just barely registering on the Barber`s Point buoy. S swell energy remains at background levels into the weekend before a medium to long period SSW swell builds late Sunday into early next week. Slightly elevated surf along E facing shores continues until trades weaken this weekend.

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.
