The Green Flash of the Sunset

Hale Lihi Kai SunsetAloha again from the Big Island. It looks as if the storm that just came through will bring snow to Mauna Kea and possibly Mauna Loa. Its actually great for the islands dry spell. The waves are truly starting to get bigger also so make sure you always check on the changing weather and wind and water conditions before heading out.

One of the greatest things you can see here is the Sunset going into the ocean on the horizon.
Sometimes you will see a Green Flash as it looks like its going into the ocean.

What is the Green Flash you ask?

Well you have to be right on the Coasline to experience it, which Puako is. Some places on land see it at sunrise and sometimes sunset.

Is it real or, as Frank Deford pondered in his December 1999 article on the Florida Keys, “just a Keysian Loch Ness Monster”?

“When rays of light enter the atmosphere , the’re bent, and the amount of bending depends on the wavelengths,” says Andrew T. Young, an astronomer at San Diego State University.

“The blue and green end of the spectrum is normally bent more: the red and orange end of the spectrum is bent less.”

The colors are seperated as if by a prism. On a hazeless , flat horizon, when the sea or land is sharply warmer or cooler than the air, red and orange wavelengths vanish, leaving blue and green dominant. The result : The sun’s disk briefly flashes green.

So yes there truly is a Green Flash here in Puako. Most of our shorline luxury vacation rentals experience a true green flash.
