In an earlier post concerning my winter swim in the ocean, I mentioned that the water was somewhat chilly but that the swim was glorious. Of course, I used some poetic license to emphasise the water’s temperature. My mother decided to write me an email to point out that the water in these parts was 18.1 degrees and that such a temperature is not so cold. I am not sure where my mother found such a statistic, for today I went for another swim. This time I was in the water, swimming laps in the ocean baths, for about 20 minutes. And the temperature: 15 degrees. This was obtained by simply putting a thermometer in the water (as the lifeguard does each day).
