General & Geography

Kos is located in the Eastern Aegean and, together with Rhodes and Karpathos, belongs to the Dodecanese group of islands, which includes about 25 inhabited islands.

The Greek island of Kos is home to around 35,000 inhabitants, most of whom live in the town of Kos of the same name with around 20,000 inhabitants.

Kos is situated directly at the entrance to the Gulf of Gökova and is at the shortest point only four kilometres away from the Turkish city Bodrum. The highest elevation of the island is the up to 846 meter high Dikeos massif in the east of Kos.

In addition to its beautiful, almost 19 miles of sandy beaches and top-class holiday hotels, Kos is also known for its charming villages and fertile plains, which are used for growing citrus fruits, almonds and grapes, among other things.

The journey usually takes place via the island’s own airport Kos-Hippokrates, which is served by several Greek airlines.

The warmest month is July, the sea heats up during the summer and is therefore generally still pleasantly suitable for swimming until the end of October.

    Lena, 32 years old was there in June

    Been there a week. On almost every day viiiiiel sun, very rarely light veil clouds. Besides always a light wind, at the coast also sometimes stronger, but so the temperatures of 26 to over 30° were very pleasant. Only on one day it was cloudier and 2-3 drops of rain came down.
    Perfect travel time in the first half of June, as the main season has not yet started, so that we had plenty of space on the beaches, a large sandy beach even for hours on our own!

    Weather Rating: 5 stars – Excellent

    Peter, 51 years old was there in September

    perfect travel weather in september, absolutely best travel time for kos. the families are then back in germany, the prices are cheaper and the beaches are much more relaxed. i find the climate absolutely perfect. by the way, no worries about refugees on the island: there is a lot of media exaggeration. you can’t believe everything that is pushed up as a story.
