Kos in September: the weather and best activities for your holiday
When one thinks of Greece, ancient ruins, olive groves, and sun-drenched beaches often come to mind. Yet, there's a gem tucked away in the Aegean Sea that tends to slip under the radar – the island of Kos. This tranquil island, rich in both history and natural beauty, provides a Greek experience like no other.
September ushers in a sweet spot in the calendar, when the intensity of the summer heat starts to dwindle, and the heavy influx of tourists begins to ebb away. So, is it a good time of year to visit Kos? Absolutely! It's a month that combines the tail-end of summer warmth with a soothing introduction to the charms of the autumn season.
Kos weather in September
The temperature during September is typically a pleasant mix of summer warmth and cooler nights. The daytime sees a comfortable high of around 26°C (79°F) which provides a perfect backdrop for outdoor exploration, whether that's cycling through olive groves or meandering through historical sites. As the sun dips over the horizon, temperatures tend to fall to a refreshing 17°C (63°F), inviting you to enjoy a relaxing dinner al fresco under the star-studded sky.
The island relishes approximately 10 to 11 hours of sunshine daily in September. Sunbathers can rejoice, as the sun's intensity is still notable, although not as overpowering as the peak summer months. The shift from summer to autumn offers a softer sunlight, creating a gentle warmth that leaves a kiss of a tan on your skin.
The sunrise and sunset during September are sight to behold. The sun typically rises around 7:00 AM and sets close to 7:30 PM, offering ample daylight for exploration.
Humidity levels in September are moderate, typically around 60%. This level of moisture in the air is comfortable and manageable for most people. Combined with the mellow September temperatures, the climate becomes agreeably balmy rather than sweltering or sticky.
Rainfall in September is scarce, with Kos receiving around 10mm of precipitation spread over 3 to 4 days in the entire month. You'll likely encounter bright blue skies, rather than grey clouds, on your trip, making it an opportune time to explore the island without having to carry an umbrella.

While the high season in Kos peaks in July and August, September sees a decrease in visitor numbers. This doesn't mean the island is deserted, far from it. But the bustling streets and beaches have more room to breathe, and local establishments offer a more relaxed, intimate atmosphere.
Tourists during this time of year hail mainly from Europe, with a substantial number of visitors from the UK, Germany, and the Netherlands. The lighter tourist footfall coupled with the pleasant weather makes Kos an attractive destination in September.
The lower influx of tourists also means that September can be a more cost-effective time to visit Kos. Accommodation and flight prices tend to be lower than in the peak summer months, allowing your budget to stretch further.
For families with young children, September is an ideal time to visit. The temperatures are mild enough for kids to enjoy outdoor activities comfortably, and the lesser crowds make family outings less stressful. From visiting the ancient ruins of Asklepion to exploring the 'Hippocrates' Plane Tree' in Kos Town, there are plenty of family-friendly experiences to be had.
Clothes to pack for September in Kos
Dressing for Kos in September is all about embracing the balance between summer warmth and autumn coolness. Pack lightweight clothing such as t-shirts and shorts for the daytime, when the island basks in the soft, mellow heat. As the evening rolls in, bringing a cooler breeze with it, a light jacket or a cozy shawl would be perfect for those al fresco dinners under the starry night sky.
The best months to visit Kos
The best months to visit Kos are May, June, and September. May marks the start of the warm season, yet the tourist influx is still moderate, allowing you to enjoy the island's beauty without the crowd. June brings more sun and warmer temperatures, perfect for those who wish to bask on the beaches or dive into the azure Aegean Sea. September, as already mentioned, offers an excellent blend of pleasant weather and fewer tourists, providing a more relaxed atmosphere while still enjoying the warm sea and plenty of sunshine.
