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.

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

It’s mostly cloudy early this morning here at my location, with a low temperature of 57.3 degrees, and the relative humidity is 82%.

12pm, it’s cloudy here on Maui with lots of volcanic haze.

505pm, it remains cloudy pretty much statewide, and radar showers quite a few showers taking aim on Oahu, some of which are locally heavy.

605pm, definitely cloudy with still that haze over Maui County.

635pm, a fog bank is just up the mountain from here, no more than 1/4 mile away…with just the slightest mist here.

Hawaii’s Broad Brush Weather Overview…as of 839pm Sunday:  The cold front has dissipated into a trough and remains northwest of the Hawaiian Islands tonight. High pressure will build in from the north and allow the trade winds to strengthen Monday through Wednesday.

Brief passing showers will favor windward and mountain areas in the overnight to early morning hours through Wednesday, and then over southeastern slopes and island interior sections Thursday onward. Winds will weaken and veer slightly from a more east-southeast direction Thursday on into the weekend. Shower activity will remain limited during this time period.

Short Term Update…as of 839pm:  The large band of high level cirrus clouds, and mid level altostratus clouds currently over the islands, will continue to slowly diminish through Monday. The cold front approaching the islands has stalled and diminished into a trough just northwest of the island of Kauai. Trade winds blow into the area and strengthen into the moderate to locally breezy range Monday through Wednesday.

A slight decrease in wind speeds and a shift from a more east-southeast direction remains in the forecast Thursday onward, as another cold front approaches the islands from the northwest, weakening and lifting the ridge north of the state. Local scale sea breeze winds will develop along terrain sheltered slopes of each island as the large scale winds weaken. Limited shower activity will prevail into the upcoming weekend with only brief showers possible.

Hawaii’s Weather Details…as of 302pm Sunday: The trough upstream of Kauai has made little to no forward progress today, sea breezes have struggled to establish owing to abundant high clouds, and showers southwest of Kauai and Oahu have essentially remained in place. In addition, regenerating showers over windward Oahu have dissipated in response to backing low-level flow. All told, an uneventful, cloudy, and mostly dry day across the state.

Going forward, building heights over the north central Pacific will maintain strengthening. This in turn ensures the return of trades tonight which then become breezy during mid-week. Winds diminish slightly by late week as trades veer to east-southeast in advance of another round of upstream height falls. Typical trade wind weather anticipated throughout this time with showers focused windward and mountains. High clouds gradually clear from west to east Monday into Tuesday before exiting the area altogether by Wednesday.

Hawaii’s Marine Environment…as of 302pm Sunday:  A dissipated front will linger into Monday just northwest of the area. Fresh to locally strong easterly trades will build in by Tuesday as surface ridge strengthens to the north. Winds will maintain strength but veer east southeast towards the end of the week, as another system approaches from the west. Surf along north and west-facing shores will be above seasonal average as a northwest swell (310 degrees) is expected to impact through Monday. Surf should remain small though the week with a small northwest rise expected next weekend. Surf along exposed east-facing shores will be a bit elevated due to a short-to medium-period northeast (40 degrees) swell, then decline Tuesday. However, short period and choppy conditions are expected to return by Tuesday as fresh trade winds redevelop and expand upstream of the state. Surf along south-facing shores will remain near the seasonal average into March.

Interesting:  $4.6M to Restore Coral Reef in American Samoa

new $4.6–million multi-institute collaborative project to help grow coral restoration capacity in American Samoa will begin in early 2026, leveraging more than two decades of coral heat tolerance studies to inform a restoration with resilience approach.

The project will bring together partners from American Samoa Community College, University of Hawaii Sea Grant College Program, American Samoa Department of Marine and Wildlife Resources, UH M?noa and Old Dominion University with local agencies and village leaders to focus on restoring healthy coral reefs and training the next generation of natural resource managers.

American Samoa has some of the healthiest coral reefs within inhabited U.S. waters that are exceptionally heat tolerant, as well as the world’s oldest continuously monitored coral reef transect, making it an excellent coral reef study site. American Samoa also has the highest rate of relative sea-level rise recorded within the NOAA global tide gauge network. Since the fringing reef crests (the shallow part of the reef where the waves break) remove up to 97% of wave energy before reaching the shore, maintaining healthy reefs is key to protecting the land. Coral restoration, where corals are grown and outplanted onto the reef, is one method of helping reefs recover from impacts such as storms and ship groundings.
