Where Celsius And Fahrenheit Meet
When we calculate water temperatures between Celsius and Fahrenheit, there are certain pairs of numbers that we always remember:
31°C = 87.8°F (hint: FINA maximum water temperature for competitions)
20°C = 68°F (hint: comfortable water temperature under warm sun)
16°C = 61°F (hint: flip around the numbers)
10°C = 50°F (hint: nice round numbers)
5°C = 41°F (hint: Ice Mile maximum water temperature)
0°C = 32°F (hint: freezing point)
But Lewis Pugh shared with us a point on the Celsius-Fahrenheit scale where the Celsius and Fahrenheit numbers meet:
-40°C = -40°F
But how in the world did Pugh understand this numerical meeting of Celsius and Fahrenheit?
When he recently swam in the Ross Sea during his Five Swims in Antarctica for 1 Reason event, he encountered -37°C air temperatures when he was swimming in -1°C water.
While one could easily imagine that swimming in such low water temperatures would be a major issue, Lewis said a major issue was air temperature and wind. "When the waves were coming over me, they would freeze in the air and become solid. When the waves hit the side of my escort boat, they had frozen solid and would crack against the boat."
Nearing -40°C (or -40°F) is certainly a condition that very few swimmers experience...from the water...in Speedos.

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.
This, for example, was the purpose of the traditional farmers almanacs. It enabled farmers to determine as accurately as possible which crops to plant for the greatest harvests in a given year.
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...

The trends are very clear.
The tide is rising for open water swimming.
