I also like when the temperature of the water is a bit warmer :D
Though I suppose it is all just the perception. We have a friend who swims almost every day of the year in the sea, just not when the waves are too big. So for him, the temperature is not a problem, and he is not young. He is maybe healthier than me.
The meeting with fellow hivers is always a great experience, especially if we are from different countries. What are a few thousands of km for a meetup? :))
The water issue repeats every few years, we have dry seasons and then in one year there is so much rain that covers the lack of all those dry years. And yes, it causes some troubles, but it will be ok soon :)
