Kos Climate & Weather

Kos Climate and Weather

The Kos climate is typical of the Greek islands and ensures hot, dry summers and mild winters. In July and August temperatures are at their hottest and range from 82ºF (28ºC) during the day to 72ºF (22ºC) at night. It can get substantially hotter than this during heat waves though. Rainfall is almost non-existent in summer but showers can be expected between October and March. If heat bothers you or you are not used to it peak summer is not the best time to visit Kos, but it is the most popular time and the island gets extremely crowded with jam-packed beaches. If you want to avoid the worst of the crowds and the most oppressive heat, we think the best time to visit any of the islands is in late spring or early autumn. May is a lovely month on Kos with the island feeling fresh and lush after its recent spring awakening, and the seas are getting warm enough for swimming by this time; September is also very pleasant with the ocean as warm as in summer and all the fruit ready for harvest. Winter is the clear loser in the seasonal contest but some visitors, intending to explore the archaeological and historical wonders of the island, do enjoy this cold but uncrowded and cheap period.
