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: Breezy trade winds driven by high pressure to the north, will weaken to moderate levels by Wednesday, becoming land and sea breezes this weekend. Lingering windward clouds and showers tonight trending drier Wednesday. A possible front near the west end of the state early next week.

Hawaii’s Weather Details: Satellite imagery shows clouds and showers associated with an old frontal band anchored along windward Maui and Big Island, and to Molokai, Oahu and Kauai to a lesser degree. Expecting this low cloud cover to linger tonight with conditions becoming sunnier through the day Wednesday.

Occasional high clouds will continue to track over the islands from a system west of the state that is not expected to impact the islands at least within the next 5-days. Breezy trade winds driven by high pressure to the north will weaken by Wednesday as the ridge builds in. While the short term trend will be drier and more stable, any clouds and showers in the trade winds will focus windward and mountains through Friday.

The system will organize to a cold front and begin approaching the state late in the week. Winds will veer southeasterly across the state by the weekend as it nears Kauai. Localized sea breezes will prompt leeward clouds and showers during the afternoons and clearing at night. Long range model solutions slow and stall the front near or over Kauai around next Monday or Tuesday.

Hawaii’s Marine Environment: Surface high pressure far north-northwest of the waters will drift east through Wednesday, as low pressure far to the northwest of Kauai remains nearly stationary and weakens. Easterly trade winds will strengthen over the majority of the coastal waters into the fresh to strong range, as the Small Craft Advisory (SCA) has been extended due to a combination of winds and seas. The SCA will be trimmed to the windier waters and channels around Maui County and the Big Island Wednesday.

The high pressure north of the waters will weaken as it passes north of Hawaii on Wednesday, coinciding with the weakening low, thus gradually weakening the winds and veering to the southeast to south by the end of the week. An area of low pressure looks to redevelop and push a surface ridge near Kauai by the weekend.

The current small north swell will continue to gradually decline into Wednesday. A moderate, medium period north-northeast (010-030 degrees) swell will arrive late Wednesday and peak Thursday and Friday. Surf along north facing shores could approach the High Surf Advisory level during the peak, with the largest swells favoring the eastern end of the island chain, and a Marine Weather Statement will likely be needed for harbor surges at Kahului and Hilo. The north swell will decline over the weekend as a small northwest swell arrives.

Surf along east facing shores have increased, coinciding with the short period energy from the building trade wind energy. Strong trades will produce rough and choppy conditions through Wednesday, mainly over the western islands, peaking near or briefly at High Surf Advisory levels for east facing shores before declining. Short period trade wind swell will decline by Christmas, but wrapping northerly swell will affect exposed eastern shores into Friday. Surf along south facing shores will remain very small through the week.

Interesting: Earth’s Growing Heat Imbalance Driven More by Clouds Than Air Pollution, Study Finds

Earth is taking in more energy than it releases back to space—a growing “energy imbalance” that is fueling global warming. A new study led by scientists at the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science finds that recent changes in air pollution are not the main reason this imbalance has increased.

Aerosols—tiny airborne particles from sources such as pollution, wildfires, and volcanoes—can affect how clouds form and how much sunlight Earth reflects back to space. While aerosols can influence climate regionally, the new research shows their recent global impact has been small.

Published in the journal Science Advances, the study analyzed nearly two decades of satellite observations combined with modern atmospheric reanalysis data. The researchers found that aerosol changes have affected the climate in opposite ways in the two hemispheres.
