A late summer holiday to Kos blends sunshine, culture and plenty of relaxation, with a calmer, more authentic atmosphere. It’s essentially the sweet spot between peak season energy and off-season quiet, AKA the perfect time to fall in love with one of Greece’s most enchanting islands. 

Here’s why a September or October holiday to Kos is always a good idea...

The weather 

This is probably the most important point! In September and October, you get to enjoy balmy sunshine without the sticky heatwaves. Throughout these months, Kos enjoys beautifully warm days averaging 25-28°C, but the intense midsummer heat has eased, so you can sunbathe and sightsee a bit more comfortably. 

The Aegean Sea that surrounds Kos also stays at its summer temperature, making it ideal for swimming, snorkelling and water sports, well into October. Once the sun’s gone down, you can enjoy mild evenings, perfect for al fresco dining in a harbourside taverna. 

Nature’s in full bloom 

Kos’ fertile landscapes are famous for vineyards, olive groves and fig trees. And late summer brings the grape harvest, so wine lovers can enjoy fresh local vintages and seasonal produce at its best.  

Cycling and hiking trails, especially around Mount Dikaios, are stunning at this time of year too, where you can take in panoramic sea views across to neighbouring islands. 

Fewer crowds 
Kos is a hugely popular Greek island throughout the peak summer months, but by late summer, the crowds dwindle. This means, quieter beaches, shorter queues at attractions and a more relaxed pace everywhere you go. Plus, you’ll get to see it at its most authentic and experience it how the locals do! 

Whether you’re exploring the cobbled streets of Kos Town or cycling along the island’s scenic coastal paths, you’ll find more space to breathe it all in and take a moment to enjoy the island’s charm. 

More time to soak up the history 

Beyond its beautiful beaches, Kos boasts an impressive cultural heritage. Late summer is the perfect time to explore historical landmarks like the ancient Asklepion healing temple, the medieval Castle of the Knights and numerous Roman ruins scattered across the island. With the milder temperatures, walking tours become far more enjoyable, and you can take your time soaking in the stories that shaped this island without the queues or tourist crowds.
