The Tsugaru Current Runs Strong Unpredictably
Brad McVetta, a Triple Crown swimmer with successful swims across the English Channel and the Catalina Channel, and around Manhattan Island, struggled across the calm 19.5 km Tsugaru Channel for 17 hours 13 minutes. The fluctuation of the water temperature in the channel also did not help matters. The water varied between 15ºC (59ºF) at the start on his swim on Aomori Prefecture to 20ºC (68ºF) in mid-channel, and then back down to 15ºC as McVetta was approaching Hokkaido.
The Tsugaru Current whips around the southern edges of Hokkaido and kicks up some large, unpredictable eddies that draw up the colder water from the depths to the surface. It is a double punch that has taken down more than one tough channel swimmer. With the sun setting, McVetta could not make any progress against the Current that no hurry to turn, so he retired with 8 km to go.

The Other Shore
The Other Shore follows world record holder and legendary swimmer Diana Nyad as she comes out of a thirty-year retirement to re-attempt an elusive dream: swimming 103 miles non-stop from Cuba to Florida without the use of a shark cage. Her past and present collide in her obsession with a feat that nobody has ever accomplished. At the edge of The Devil’s Triangle, tropical storms, sharks, venomous jellyfish, and one of the strongest ocean currents in the world, all prove to be life-threatening realities. Timothy Wheeler’s documentary brings Diana Nyad’s extraordinary adventure to life as Diana sets out to prove that will and determination are all you need to make the unimaginable possible.
2014 Open Water Swimming Almanac
An Almanac for Open Water SwimmingAn almanac is essentially a body of knowledge which is so complete that it enables people in different fields to make predictions about the future of their respective industries.

But the farmers almanac was just one example among many.
There are, of course, many different kinds of almanacs.
In fact, there is even one for open water swimming...
