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: An old remnant frontal boundary moves swiftly through the islands today, with a brief boost in showers and breezy trade winds. Easterly trade winds will quickly decrease tonight through Wednesday, with a hybrid light to moderate east-southeasterly wind and sea breeze pattern setting up over the islands from Wednesday night through the Christmas holiday weekend.

Shower activity will be limited from Wednesday onward after the remnant cloud band passes through the state. An approaching upper level disturbance on Sunday will spread significant high level cirrus clouds from west to east across our area. This upper disturbance will increase state-wide shower trends in a light southeasterly wind pattern for the first half of next week.

Hawaii’s Weather Details: Satellite imagery shows a high pressure ridge in place north to northeast of the Hawaiian Islands, a deep low and cold front far northwest of the state tracking northeastward, and a narrow low level cloud band drifting through the islands this morning. Breezy trade winds will push this narrow remnant cloud band through the islands today, enhancing shower trends for all islands, especially over the typical windward mountain slopes.

The cold front trailing the low northwest of the islands will approach the Hawaii region from the west and stall long before reaching the western most island of Kauai. However, the main impact to island weather will be a change in wind directions as the high pressure system far north of the state drifts east, parking a low level ridge directly over the island chain. Wind speeds will weaken and veer more from a east to southeast direction from Wednesday night through the Christmas holiday weekend.

Another impact of this ridge over the state will be felt in the large scale subsidence, or stabilizing downward vertical motions that will warm and dry the air over each island. Subsidence temperature inversion heights will lower, decreasing vertical cloud growth and keeping shower activity to minimum during this time period. Only brief passing showers remain in the forecast and any rainfall amounts will be light.

By early next week, another shallow cold front approaches Kauai from the northwest. The latest model guidance suggests this weak frontal trough will stall long before reaching the islands. However, a more interesting pattern is brewing in the upper levels, as a passing and strong upper level trough will deepen into an upper low near the islands. Extended range weather model solutions project this upper low to pass from west to east across the entire state during this time period.

If in fact this long range model solution works out as predicted, then all islands will see rain shower enhancement in a light wind sea breeze wind pattern. Rainfall activity will favor island mountain and interior sections, with decent rainfall potential for even the normally drier leeward sections. Stay tuned as this extended range forecast period will certainly evolve over time.

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.
