September turns Turkey into a dream destination, combining the perks of the summer season with the comfort of autumn. Average temperatures dip slightly, sitting between 28-32°C during the day, while evenings turn mild and perfect for relaxed strolls.

Unlike July and August, when the blazing sun can be overwhelming, in September you can enjoy the beach, the pool and various outdoor activities without any discomfort. This period is excellent for families with young children, who avoid the hot midday hours, and for couples looking for a calmer, more romantic atmosphere.

Another major benefit is sea temperature. After soaking up heat all summer, the Mediterranean and Aegean waters reach peak thermal comfort. So you can swim in excellent conditions, with water temperatures holding between 26°C and 28°C on the Antalya coast, and slightly below that in the first half of the month on the Aegean coast.

What's more, September often brings more attractive all-inclusive stay deals, especially towards the middle and end of the month, as demand starts to drop, letting you enjoy premium hotels at more affordable prices. This combination of perfect weather and optimised costs makes a holiday in Turkey in September a smart decision and an investment in an unforgettable experience.

If the boutique charm of the Aegean coast has won you over, but you'd rather have a firmer guarantee of warm weather well into autumn, the Antalya coast is the answer. This region prides itself on Turkey's longest summer season, and September remains high season, albeit a much more relaxed one.

Here, Antalya's weather in September means sunny days and steady temperatures, with minimal chances of rain. Charter flights to Turkey keep running to Antalya unhindered throughout the month, giving you maximum flexibility when planning your holiday. This area is ideal for families thanks to impressive all-inclusive resorts and wide, fine-sand beaches.

For anyone wanting to stretch summer as far as it goes, Alanya and Side are the jewels of the Antalya coast in late September. This is where it's warmest in Turkey in September, with sea temperatures that can reach as high as 27-28°C, and pleasant air around 28-30°C.

These resorts offer fine-sand beaches and a gentle entry into the sea, ideal for a family holiday with children in Turkey. Alanya, the southernmost resort, benefits from a privileged microclimate that lets it hold onto high temperatures even into October. Beyond the beach, you can explore Alanya Castle or the Damlataş Cave.

Side, a town with a rich history, blends the beach perfectly with ancient archaeological sites, offering an ideal combination of relaxation and culture, especially with temperatures in Alanya and in Side staying so pleasant in the autumn.

Kemer is a destination of unique beauty, sitting at the foot of the Taurus Mountains, with dramatic scenery where mountains meet the sea. The luxury resorts are surrounded by pine forests, and the atmosphere is calm and sophisticated.

That said, it's worth knowing that the mountainous terrain, while picturesque, can bring an increased risk of short, sporadic showers towards the end of September, particularly compared with Alanya or Side. If guaranteed sun right to the last ray is your priority, Admiral.Travel recommends looking at the more southerly resorts on the Antalya coast for the second half of the month.

September is the ideal month to explore Turkey's cultural and natural treasures, far from the sweltering summer heat. Here are a few unbeatable suggestions, available through Admiral.Travel's organised excursions:

These excursions take on a whole different flavour in September, when you can explore the ruins, terraces or valleys without fighting the daytime heat.
