This summer I went to Lake Balkhash. The weather was very hot and sunny. The water was warm. I went with my friends (а куда?). We bathed and played beach volleyball. In the evening we ate fried meat and a water-melon . We were three days there.But for the third day weather strongly deteriorated. There was a cold wind and rain. We couldn't swim, because it was cold and we walked on the coast. At night the moon was reflected in the lake. It was very beautiful.
