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: Passing weather systems to the north will keep light to moderate east to east-southeast winds and drier conditions in place for much of this week. A cold front will approach the state during the second half of the week, but likely stall and diminish west of Kauai over the weekend.

Hawaii’s Weather Details: A surface ridge remains just north of the islands, with plenty of mid- to upper-level ridging. The precipitable water shows a large area of drier air moving into the area from the east, which is also reflected in the afternoon soundings from Hilo and Lihue. As a result, the visible satellite imagery shows only scattered clouds over most of the island chain, moving into windward areas and developing over some leeward terrain, where sea breezes have developed in the more wind-sheltered spots.

This dry and stable weather pattern will continue for much of this week with little variation overall. Trade wind speeds will be somewhat subdued, as a series of cold fronts pass by farther to the north this week, weakening the ridge.

By Wednesday evening, a stronger cold front moves closer to the state, driving the weakened ridge farther south over the Hawaiian Islands Thursday to Friday. Lighter east to southeast winds will develop Thursday onward into the weekend, expanding the coverage of daytime sea breezes to leeward areas of all islands.

Not much in the way of showers expected during this time period as well, with the ridge over the islands keeping conditions fairly stable. One exception to this rule will be along the southeast slopes of the Big Island, where southeasterly wind flow will lift clouds up the slopes of Mauna Loa, potentially enhancing clouds and showers over Kau and Puna Districts.

These lighter winds will continue through the weekend, as the approaching cold front appears to stall and dissipate just west of Kauai. Light southerly winds ahead of this front may increase shower activity over Kauai and Niihau Saturday and Sunday, however, model solutions are fairly inconsistent on this from run to run.

The rest of the state will likely remain on the drier side in a hybrid sea breeze/east-southeast wind pattern. Long-term guidance is hinting at another cold front approaching the islands early next week, that may bring some southerly winds and wet weather to portions of the state.

Fire weather:  Winds and humidity levels will remain below critical fire weather thresholds this week. Brief passing showers will trend higher during the typical late afternoon to early morning hours. Temperature inversion heights will range from 5,000 to 6,000 feet elevation near Maui and the Big Island.

Hawaii’s Marine Environment:  The pressure gradient back to the surface high centered far northeast of the islands will weaken as the high moves east. Thus, moderate to locally fresh easterly trade winds will begin to fall off through the week. A large North Pacific storm will push a cold front to the vicinity of Kauai and Niihau by the weekend. The approach of the front will weaken and veer winds more southerly through the holiday.

The tail end of this front will likely pass north of the island chain early next week. A decent size northwest swell passage over Thanksgiving may push seas to near Small Craft Advisory thresholds. A large northwest swell will likely lift seas to SCA heights by this time next week.

Moderate size, medium period northwest swell (320-340 degree) will continue to fall through Tuesday. This will result in near head high surf over better northern exposures, before falling to waist high by Tuesday. A slightly larger size, long period northwest swell (330 degree) is scheduled to arrive Wednesday, fill in and peak on Thursday. This swell will result in solid High Surf Advisory level surf with the possibility of surf just touching High Surf Warning heights during its peak Wednesday night into Thursday morning. A large storm force low moving up from the West Central Pacific may drive a very large northwest swell toward the islands late this week. As of now, this swell is forecast to arrive early next week, and could generate XL size surf along north-facing shores.

Interesting: What’s Happening to Our Food?

Several UC San Diego-led projects take a closer look at the safety and sustainability of seafood.

If you spend any time in San Diego, you know seafood anchors the local culinary scene. From Baja-inspired fish tacos and artfully prepared sushi to hearty surf-and-turf plates and fresh market catches, the options are endless.

Beyond its West Coast flavor, seafood also delivers a major economic kick. According to the most recent National Oceanic and Atmospheric Administration’s fisheries report, commercial and recreational fisheries in the U.S. generate an estimated $321 billion in sales annually and support roughly 1.7 million jobs. Seafood also offers numerous health benefits, serving as a heart-healthy source of lean protein, particularly species such as anchovies, mackerel and herring that are rich in omega-3 fatty acids.

Yet the vital seafood industry faces threats from pollutants, parasites and environmental changes that put both marine life and humans at risk. So, what’s happening to our food — especially our seafood — and how concerned should consumers be?
