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’s Broad Brush Weather Overview…as of 317am Sunday: A light east to southeast wind pattern will continue through this afternoon, as a weakening cold front approaches Kauai from the west, breaking down the ridge over the Hawaii Region. Local scale onshore sea breezes will form over terrain sheltered leeward areas due to the lack of large scale winds. The eastward movement of this front will stall near Kauai today and Monday, as the front dissipates near the western edge of the state.

Moderate to locally breezy easterly trade winds will strengthen across the Hawaii region from Monday through Wednesday, with brief passing windward and mountain shower activity. Trade winds weaken again with returning sea breezes from Thursday onward, as another weak cold front approaches the islands from the northwest.

Hawaii’s Weather Details…as of 837am Sunday:  Three areas of interest exist on the regional radar composite. The first is a band of showers and isolated thunderstorms west of Kauai, that exists along a corridor of weakly convergent SW flow, that is perhaps slightly frontal in nature, but it isn’t particularly impressive overall. Nonetheless, it has shown an ability to capitalize on the weakly stable & moderately saturated mid-levels observed on the atmospheric soundings out of Lihue and Hilo.

Upper support rapidly fades this afternoon and deep layer flow above the boundary layer becomes more uniformly southwesterly causing convergence to be lost. This will leave the existing band of showers in a rapidly decaying state as it encounters low-level trades that will likely halt eastward progress of its remnants. As such, expect any showers today to organize along corridors of convergence within island interiors

The second focus of interest is a batch of showers presently located southwest of Kauai and Oahu and lifting toward the islands. These showers exist within a relatively deep pocket of moisture preceding the front, but appear largely driven by convergence in the lee of the islands, as ESE wind flow wraps through the channels. The bulk of this activity will likely remain southwest of the islands, but a few showers may creep over the western islands during the day.

Sea breeze development will be hard to come by today given extensive high clouds, but if convergence can materialize over interior Kauai and Oahu, we may see a boost to shower depth as it erodes existing stability.

Finally, the ESE flow has maintained a static area of shower regeneration along the Windward Coast of Oahu since yesterday. Low predictability of this feature exists due to its small scale, but given that the environment will undergo little change during the next 12 hours or so, it is hard to argue against persistence. There could be the potential for nuisance flooding, especially given observed rises that occurred on the Waikane Stream with this activity last night, but rain rates remain solidly below 1″/hr at this time. Trades return tonight.

Hawaii’s Marine Environment…as of 317am Sunday: Moderate to locally fresh east to southeast winds will continue as a weakening front stalls and diminishes near the western end of the state. This will allow localized land and sea breeze conditions to develop near sheltered coasts, particularly for the western end of the state closer to the trough. Fresh to locally strong easterly trades will return by Tuesday as a surface ridge strengthens to the north, at which time Small Craft Advisories will likely be needed for the typically windy waters of Maui County and the Big Island.

Surf along north and west-facing shores will continue to trend up slightly, as a fresh west-northwest swell arrives from a broad gale that was located south of the Aleutian Islands near the Date Line. This swell will peak into Monday before gradually lowering by mid-week.

Surf along exposed east-facing shores will trend up slightly as a fresh, short- to medium-period northeast swell from a gale centered around 1200 nautical miles northeast of the state arrives. 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.
