@terryliv Well yes, I know it is rather boring to swimm in deep and clean fresh water. We unfortunately to not have the fun and thrill of currents, dangerous tides, kingwaves, sharks, marine stingers, etc.. But if you refer to the temperature, I swum into much colder water in Australia, still also with all those hazards, it is much better than our lakes.
@novab Hi Nova, yes it is really warm enough, it takes a while to warm up, as our lake is 400 meters deep, and it is not the Carribean, but still nice. We have temperatures somehow around 28-32°C, which is already to warm for me, and the top layer of the water is something around 21-22°C. Wonderfully refreshing.
