Introducing a precise open water swimming temperature scale

I get asked various questions related to cold because I like to write about it. Those questions often inspire further writing ideas. One thing I realised was there was no good agreement on cold water. A poll of open water gave the following results. Under 5ºC (41ºF) – 0% Under 10ºC (50ºF) – 7% Under 12.5°C (54.5°F)…


Best wishes to my friends in London tomorrow. So sorry that I am not there after the organising and all the cold water training. Sylvain, I’m really sorry to miss you before your antipodean adventure. Best wishes to you and Greta on your travels.
