Hawaii Weather Narrative


Broad Brush Overview: A fair weather pattern will continue, with light and variable winds for the time being. An approaching cold front from the northwest will cause winds to shift towards a more southerly direction with scattered showers Wednesday. As we push into Thursday and Friday, a cold front will move through the state, spreading clouds and showers over each island. Look for a return to trade winds Friday afternoon into Saturday with typical windward and mountain showers. Yet another cold front approaches the islands for the first half of next week…with another period of wet weather.

Details: A ridge of high pressure remains just north of Hawaii, keeping a light east to southeasterly wind flow over the state, with light and variable winds locally. Strong subsidence from the upper level ridge over the area will keep the trade wind inversion heights low, capping upward cloud growth through Wednesday morning. These shallow cloud heights will limit rainfall over the state, with not much shower coverage. A low pressure system moving by to the north, will be pushing a cold front towards Hawaii from the northwest.

This front and associated trough of low pressure will break down the ridge over the islands, causing our winds to shift towards a more southerly kona direction. An upper level trough associated with this system will reduce large scale downward subsidence, and lift the trade wind inversion heights to around 8000 feet…and in the process deepen the cloud depths. Look for scattered rains showers to develop by Wednesday afternoon, although focusing their efforts mainly over the western half of the state, for Kauai and Oahu.

The cold front will sweep from west to east through the island chain Thursday and Friday. Southwesterly kona wind speeds will increase ahead of the front, with chilly northerly winds in the wake of the front. Look for an 8-12 hour period of showers, starting with Kauai Thursday around noon. The frontal cloud band and showers will then reach Oahu late Thursday afternoon into the early evening, arriving over Maui County Thursday night into early Friday morning…and finally pushing through the Big Island Friday morning.

Looking Ahead: By Saturday, a high pressure system passing through the Central Pacific will bring one more day of typical moderate to breezy trade winds, with scattered showers mainly over windward and mountain areas.  Sunday finds winds veering towards a more southeasterly direction, with land and sea breezes along with mostly dry conditions…as a second cold front approaches the islands from the northwest. Scattered showers remain in the forecast for the first half of next week, as the models continue to show another cold front moving into Kauai.

Marine Environmental Conditions: A ridge of high pressure just north of the islands will keep light to locally moderate trades in place through tonight. An approaching cold front will shift winds around to the south Wednesday, with moderate to strong south to southwest kona winds expected for Thursday ahead of the front. The cold front is expected to sweep eastward through the islands late Thursday through Friday, with moderate to strong and cool north to northeast winds following the frontal passage. Moderate to strong trade winds are expected to fill in late Friday through Saturday, as a quick moving high builds eastward to the north of the state. A new approaching cold front will likely shift winds back around to the south and southeast late in the weekend…through early next week.

The current large northwest swell has trended downward, although a reinforcing northwest swell is expected. This swell will then move towards the islands, with surf heights expected to reach solid warning levels across north and west shores of Niihau and Kauai, with High Surf Warning (HSW) threshold for the west/north facing shores of Oahu and Molokai, and north facing shores of Maui. The High Surf Advisory (HSA) remains in effect for the west facing shores of the Big Island as well.

The swell will gradually lower Wednesday through Thursday, although advisory level surf will likely hang on across north and west facing shores exposed to the swell through Wednesday afternoon. A new large northwest shifting to north swell will build Thursday night and Friday, then slowly lower over the weekend. This swell may reach advisory levels for exposed north and west facing shores Thursday night and Friday.

The Small Craft Advisory (SCA) for elevated seas is expected to continue through tonight for portions of the marine area exposed to the series of northwest swells moving through. This SCA may need to be extended through Wednesday. Additionally, SCA conditions may develop ahead of and behind the cold front across portions of the marine area Thursday through Friday for winds, seas or a combination of the two. A period of strong trades may also produce SCA level winds across the typically windy zones around Maui and the Big Island Friday night through Saturday.

Interesting: Wine on Mars? The World’s Oldest Wine-Making Country Wants to Make It Happen –  The first human colonists on Mars will have to forgo many of the creature comforts of Earth — things like enjoying an ozone layer, for example, or opting out of rearing genetically engineered Martian babies. Fortunately, one essential earthly amenity these hardscrabble colonists may not have to give up is wine.

Georgia, a country with an 8,000-year-old viticulture tradition, is putting its top space and wine scientists to work figuring out how to grow grapes on Mars.

The project, named IX Millennium, ostensibly as a nod to Georgia’s ninth millennium making wine, will involve several phases of research into building an agricultural infrastructure on Mars. One critical step: identifying the grape varietals on Earth best equipped to withstand the harsh radiation, fearsome dust storms and severe temperature swings of the Red Planet. This research could help hydrate permanent settlements on Mars a soon as 2024 — the year when SpaceX founder Elon Musk intends to launch the first crewed mission there. (NASA hopes to follow in the 2030s.)

“If we’re going to live on Mars one day, Georgia needs to contribute,” Nikoloz Doborjginidze, founder of Georgia’s Space Research Agency and an adviser on the wine project, told The Washington Post. “Our ancestors brought wine to Earth, so we can do the same to Mars.” (The origins of wine are still debated, but Georgia holds a valid claim thanks to their recent discovery of an old wine-stained pot dated to 6000 B.C.)

The new space wine project will kick off later this year with the installation of “vertical greenhouses” inside a hotel in the capital city of Tbilisi, according to Georgian news agency There, floor-to-ceiling pods of soil and seeds (including grapes, strawberries and arugula) will be left to grow under hydroponic lights with minimal human interference, simulating the possible conditions of a controlled agriculture pod on Mars.

In the meantime, Georgian wine experts are hard at work trying to figure out which grape varietals might best survive harsh Martian conditions. Over the next few years, researchers at Tbilisi’s Business Technology University plan to simulate a Martian environment in the laboratory, exposing soil samples to subzero conditions, high carbon monoxide levels and thin air meant to mimic the atmospheric pressure at “20,000 feet altitude on Earth,” The Washington Post reported.

These experiments likely will not bear fruit until at least 2022, but scientists already have a hunch that white wine will fare best on the Red Planet.

“Whites tend to be more resistant to viruses,” Levan Ujmajuridze, director of Georgia’s vineyard Laboratory, told The Washington Post. “So, I’d imagine they’ll do well against radiation, too. Their skin could reflect it.”

These experiments could well provide future Martians with grapevines — but the actual fermenting, bottling and aging would be up to them. Nobody knows exactly how fermenting grapes in microgravity will actually work yet, but NASA scientists think it’s possible.

The Georgia team’s boozy experiments aren’t the first foray into space agriculture. Astronauts aboard the International Space Station (ISS) have already begun growing salad crops in microgravity, while China’s recently deployed Chang’e-4 lander will attempt to grow potatoes and rockcress (a flowering plant similar to cabbage and mustard) on the moon.

The makers of Budweiser, meanwhile, have launched barley seeds into space three times in hopes of becoming “the first beer on Mars,” while a batch of Ardmore scotch whisky spent three years aboard the ISS from 2011 to 2014. That project showed Earthlings that even an old drop of the pure is apparently not immune to the ravages of microgravity; the scotch reportedly came home tasting of “antiseptic lozenges” and “rubbery smoke.”
