What’s the weather like in Kos in June?

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.


The average high in Kos during June is 29ºC, dropping to 19ºC at night so it’s still nice and warm. The sea temperature’s 22ºC while humidity’s moderate. There’s 8mm of rain over three days, and you can expect 15 hours of daylight with 13 long hours of sunshine each day. UV levels will be very high so look after yourself in the sun. Sunset’s around 8.30pm.
