General & Geography
Table of Contents
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.
Climate in Kos
Like Rhodes, Kos is known for its very sunny and pleasant climate. The island measures about 3000 hours of sunshine annually and has an absolute guarantee of good weather, especially in the summer months. The summer in Kos is hot and sunny, there is almost no rain at all between May and September.
Only from November it becomes increasingly humid on the Greek island of Kos, the winter months until about mid-March register the most precipitation. However, they are out of season in Kos anyway. As a rule, the hotels open from May to October, high season is from mid-June to mid-September.
In the course of June, the day temperatures will then crack the 30 °C mark for the first time and will remain at this high level until the beginning of September. 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.

top-quality water every day at 30 degrees.
Weather Rating: 5 stars – Excellent
We were in Lagoudi in July for 4 weeks. Had a vacation home. Super nice weather and with the car one is very fast at empty beaches. All friendly and eager. Zia for sunset a must. Riding on Erikas Horsefarm in the evening was great for our daughter. 12 times on kos.always the best destination for us.
Weather Rating: 5 stars – Excellent
Much sun but also much wind, despite waves perfect. very beautiful beach not overcrowded
Weather Rating: 5 stars – Excellent
Weather outstanding, beach not overcrowded, nice people, island to relax
Weather Rating: 5 stars – Excellent
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
We always had a lot of fun and a lot of sun it was very hot there was always a light wind
Weather Rating: 5 stars – Excellent
We were there for 10 days and all we had was sun, sun, sun!!! A light wind and temperatures of 30 degrees or above. On the last two days the wind was stronger and so were the waves.
Weather Rating: 5 stars – Excellent
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.
Weather Rating: 5 stars – Excellent
Pure sun – with a little wind – for long beautiful summer-
evenings!
Weather Rating: 5 stars – Excellent
