What’s the weather like in Kos in July?

Located in the Aegean Sea just off the coast of Turkey, the Greek island of Kos has a Mediterranean climate with hot, dry summers with mild, wet winters. July brings the highest temperatures and lowest rainfall to the island, with a gentle breeze ensuring it doesn’t feel too hot. July is a great time to relax on the beautiful beaches, try some water sports in the warm sea or explore the ancient history of Kos.


Kos has an average daytime temperature of 25°C in July, with highs of 29°C and lows of 21°C after dark. With the sea temperature measuring 24°C, the clear Mediterranean waters are ideal to cool down in after a morning in the sunshine, while still being pleasantly warm for swimming and snorkelling. 14 hours of daylight gives you plenty of time to enjoy your holiday on this stunning island, while 2mm of average monthly rainfall means the chance of showers is low.
