The air temperature stays steady at + 25-28, by the end of the month it's over +30. The first half of June on the coast can be wind, because of what lying on the beach will not be quite relaxed (may want to wear socks). The sea becomes perfect after June 15, before this time lovers of warm water can experience slight discomfort. The air is very comfortable - not too hot and at the same time tangibly warm. Evenings are mostly warm, you can go with a short sleeve, you only need to throw a stole in the first half of June.
