Do you have any idea to spend the hot summer days?

In my case, I don't feel hot in summer. I don't sweat a lot. So on a very hot day, sometimes I feel dizzy. But really, really hot day, I go to the indoor swimming pool near my house. There are not many people, and the water is also clean. Without driving to the far place, I can escape the heat. And then having one piece of watermelon makes me forget the hot weather.
