Kos is in the Aegean Sea off the southwest coast of Turkey, which gives the island typical Mediterranean weather with long, hot summers. If you’re going to this Dodecanese island in June, you’ll get great holiday weather with lots of sun and hardly any rain. Kos has a hot and dry season from May to October and a mild and wet season from November to April. There’s not much difference in weather around the island as it’s relatively flat, although there’s a mountainous region that protects the south from winds and rain. You’ll be kept cool on the coast by the sea and its welcome breezes.
