Alanya in September: Warm Sea, Softer Heat and the Joy of a Quieter Season
A practical guide to a holiday in Alanya in September: weather and sea temperatures, crowd levels, the best things to do and what to pack for your trip.
Why September? A Quick Overview of Alanya in September
A holiday in Alanya in September means enjoying the best parts of summer while leaving the toughest ones behind. The oppressive humidity of July and August gradually eases, while the sea, having warmed up all summer long, reaches one of its warmest points of the year. Head to the beach in the morning and stepping into the water feels less like cooling off and more like slipping into a warm bath.
Another advantage of September is the calm that sets in from mid-month. Once schools reopen, most families with children head home, making it much easier to find a sun lounger on the beach, book a table at a restaurant or grab a good spot on a boat trip. Even so, almost all hotels, beach bars and tours are still running at full capacity. In other words, you get everything the season has to offer without the burden of the crowds.
In this guide you will find out what the weather and sea are like in Alanya in September, how the start of the month differs from the end, the most enjoyable activities at this time of year and what you should pack in your suitcase.
Alanya Weather in September and Sea Temperature
In the first days of September, Alanya is still very much a summer town. Daytime temperatures usually range between 30 and 33°C, and the midday sun can be quite fierce. In the second half of the month, temperatures gradually drop to around 28-30°C, and the late afternoons in particular feel noticeably fresher. Nights mostly stay above 20°C, making it a perfect time for dining outdoors.
The sea temperature in September is typically between 26 and 28°C. Compared with May or June, that means a far more comfortable swimming experience: staying in the water for a long time, snorkelling or letting the kids play for hours is no problem at all.
September is a very dry month. In the last weeks you may see a brief shower or a cloudy day, but these rarely affect your holiday. Days are slightly shorter than in August and the sun sets earlier, which simply means more convenient times for watching the sunset.
Early or Late September? Two Different Sides of the Month
Thinking of September as a single month can be misleading, because the first and second halves offer quite different experiences.
The first two weeks of September feel like an extension of the summer holidays. Since schools in Turkey usually open around the second week of the month, domestic families and visitors from Europe are still out in force until then. It is hot, the nightlife is lively and the beaches are busy. If you are after plenty of sun and a buzzing atmosphere, these dates will suit you well.
In the second half of the month, the pace changes. Beaches open up, hotel prices often drop to more reasonable levels than in peak season, and a calmer mood settles over the town. For couples, retired travellers, hiking and nature lovers, or anyone who simply wants to unwind, the last two weeks of September are ideal. The slightly lower temperatures also make daytime castle visits, trips to ancient sites and tours to mountain villages far more enjoyable.
The Best Things to Do in Alanya in September
September is one of the rare months when almost every activity in Alanya can be enjoyed comfortably. With the sea still warm, boat trips are at their very best: swimming in front of Damlataş Cave, Lovers' Cave and Phosphorus Cave, or diving into crystal-clear water out at sea, is a special pleasure in September.
September is also a great month for underwater enthusiasts. With warm water and usually good visibility, a first scuba diving experience takes place on much quieter boats than in midsummer.
The softer heat makes activities on land appealing too. Jeep safaris into the Taurus Mountains, trips to Sapadere Canyon and walks up to Alanya Castle are much more comfortable in the second half of September. Conditions are generally favourable for paragliding as well, and the views over the town and coastline are especially sharp in the clear September air.
In the evenings, strolling along the seafront, enjoying a fish dinner at the harbour restaurants and watching the sunset around the Red Tower (Kızıl Kule) are among the must-dos of a September night.
Which Beaches to Choose in September
Alanya's long coastline caters to every taste in September. Cleopatra Beach, close to the town centre, remains the favourite spot with its fine sand and clear water, yet in the second half of the month you will hardly see any of the midsummer crowds. Going early and retreating to the shade before the midday heat is a good plan.
Keykubat Beach on the eastern side, thanks to its long and wide shoreline, is perfect for those who love combining walking and swimming. If you would like to get a little further from the centre, the beaches around Mahmutlar, Kestel and Oba offer a more local and relaxed atmosphere.
To the west, Konaklı and İncekum are known for their shallow, sandy shores. İncekum Beach in Avsallar, shaded by pine trees, provides a cool break during the still-hot midday hours of September.
Keep the wind in mind when choosing a beach. At the end of September there can occasionally be choppy days; on such days, sheltered coves or calm stretches of coast offer more comfortable swimming.
Packing and Planning Tips for a September Holiday
When heading to Alanya in September, most of your suitcase should still be filled with summer clothes. Light cotton or linen clothing, swimwear, a hat, sunglasses and high-factor sunscreen are essential. Although the September sun may seem gentler than in August, it can easily burn your skin at midday.
If you are travelling towards the end of the month, it is worth adding a light cardigan or a long-sleeved top for the evenings, as it can feel cool on the way back from boat trips or during excursions to mountain villages. Bring a pair of comfortable, non-slip shoes for canyon and nature tours too.
When it comes to planning, it makes sense to book accommodation and popular tours in advance for the first half of the month. In the second half you can be more flexible, but if a particular hotel or a specific tour date matters to you, booking early still avoids surprises. And since some beach businesses and seasonal restaurants start closing after mid-October, September is a safe bet when everything is still open.
Food and Local Life in Alanya in September
September is a month of transition on Alanya's tables too. The last figs, grapes and melons of summer fill the market stalls, while pomegranates and the first autumn fruits start appearing towards the end of the month. Alanya's famous local bananas, which have become a symbol of the town, are available all year round, so don't leave without tasting them.
The town's weekly neighbourhood markets are a wonderful chance to see local life up close. Alongside fresh fruit and vegetables, you will find spices, olives, regional cheeses and handmade products. Since market days and locations vary by neighbourhood, it is best to ask your hotel or tour guide for up-to-date information.
For dinner, the restaurants around the harbour and along the seafront are ideal for sitting outdoors in the mild September air. Fresh fish, a variety of meze and regional dishes, followed by watching the sunset from a quiet table after a day by the sea, are among the most memorable moments of a September holiday.
