A note on the 20°C threshold

Twenty Celsius is the rough line where most casual swimmers say the water "isn't cold". Below that, you feel the shock on entry and stay aware of it. Above, you can usually relax. It's not a hard rule. Experienced cold-water swimmers happily swim well below it, and some people find anything under 24°C unpleasant. As a single number for a global comparison, 20 is the most useful one.
