Traveling on the south of Ukraine with my wife we spent a half of a day on the sea shore. That day we were so lucky to catch a rain :) We were not too upset as a sea shore is better than an office where we are every day.
The sea where we spent that short time is Azov sea. The sea is shallow. Its biggest depth is about 15m. So, usually it is very warm. I know that even there is a rain the water is very warm.
Ok. This article is to show you an HDR photo of the sea shore. The place is very peaceful and because of raining there were not many people.
