August in Türkiye belongs to the crowds. September belongs to the travelers. The temperature drops from unbearable to excellent — 22 to 30°C depending on where you are — the sea stays warm, sites that were genuinely unpleasant to visit in 40°C heat become extraordinary, harvests begin, festivals take over the calendar, and the beaches thin out by 30 to 60 percent. September is arguably the finest month to visit Türkiye, and it is consistently underestimated by those who plan their trips in January and default to the peak weeks. This guide covers seven destinations — from the Bosphorus at golden hour to the pistachio orchards of Gaziantep — that reward a September visit in ways they genuinely cannot in any other month.
Pegasus flies to all seven destinations on this list. Check the Pegasus route map for direct connections from your home airport, and how to find cheap flights for booking early — September fares are significantly lower than peak summer on most routes.
Where the Light Turns Everything Gold: İstanbul in September
Istanbul in September operates at a frequency the summer version of itself cannot match. The crowds that filled the Hagia Sophia queues in July have largely departed. The Bosphorus light — that specific late-afternoon quality that makes the minarets look as though they are drawn rather than built — is at its best in the month before the October rains arrive. And the city’s cultural calendar, which goes quieter in summer, fires back up: the Istanbul Biennial, one of the most significant contemporary art events in the world, fills the city’s historic venues with installations and exhibitions that are worth a trip on their own. The Istanbul Coffee Festival, running for four days in Küçük Çiftlik Park near Taksim, is a more accessible affair — workshops, competitions and the opportunity to drink exceptionally good coffee while the September sun is warm enough to do it outside.
The food in September has a specific character. The fish sandwich vendors at Eminönü are doing their best business of the year — the cooler air makes the grilled balık ekmek experience more pleasurable than in the humid summer heat. Fresh pomegranates appear at every juice stall from mid-September, pressed to order. And the grape harvest produces pekmez — grape molasses — that turns up in bakeries, börek shops and at breakfast tables across the city in a way that marks the season as clearly as a calendar.
Getting there: Istanbul is Pegasus’s home hub. Direct flights from Berlin, London, Manchester and across the Pegasus European network.
Above the Fairy Chimneys, the Harvest Has Begun: Cappadocia
Cappadocia’s hot air balloon season runs year-round, but September is the month when conditions are most consistently favorable — the intense summer thermals that can ground flights in July and August settle into the calm, cool mornings that make pre-dawn launches reliable. The balloon fills and lifts in darkness, and by the time the light hits the valley walls and the tufa formations begin to glow, you are already above them. Above the Fairy Chimneys: Everything You Need to Know About Hot Air Ballooning in Cappadocia covers the logistics of booking. Book early for September — it is the season’s peak.
Below the balloons, the grape harvest transforms the villages of the Ürgüp and Avanos area through September and into October. The Cappadocia wine region — centered on the Emir grape, which grows in the volcanic soil here and virtually nowhere else — holds harvest festivals that include vine-to-bottle demonstrations, live music and, unavoidably, grape stomping. The Avanos World Dance Festival brings traditional music and dance to the banks of the Kızılırmak River in the pottery capital of Türkiye. And the cave hotels and underground cities that felt claustrophobic in summer heat become genuinely comfortable. Fly Kayseri with Pegasus — direct connection, 75km to Göreme.
Still Warm, Finally Quiet: Antalya’s September Advantage
Antalya in September is operating at full summer capacity in terms of sunshine, sea temperature and the range of things to do — but at roughly 65 percent of peak August crowds. The sea is 28°C. The ancient sites — Aspendos, Perge, Termessos, Phaselis — which were genuinely unpleasant to visit in the 38°C heat of July, become extraordinary in the 30°C weather that September delivers. The Complete Guide to the Ancient Sites of Antalya covers all of them in depth.
The Food Fest Antalya, held in Karaalioglu Park on the cliff edge above the sea, runs for three days in September and covers both traditional Turkish regional cuisine and international food in one of the most dramatically situated park venues in the country. The Kaleiçi old city — Antalya’s Roman-walled historic center — fills with restaurants doing the specific late-September menu that marks the harvest season: pomegranate molasses on grilled meats, fresh Taurus mountain figs with clotted cream and wild thyme honey, şeftali kebab at the meyhanes where the outdoor tables are finally comfortable after dark. The Antalya summer guide covers beaches and the wider destination. Fly Antalya with Pegasus — direct from 15 German airports and all five UK airports.
Where the Ancient World Takes a September Breath: Ephesus and İzmir
The 9th of September is İzmir’s Liberation Day — the anniversary of the city’s liberation in 1922 at the end of the Turkish War of Independence — and the city celebrates with a genuinely significant civic energy: concerts, public gatherings, fireworks over the bay, and a historical consciousness that gives the day a weight that purely festive occasions rarely achieve. The İzmir International Fair, one of the largest trade fairs in the Middle East and Europe, takes over the city for much of mid-September and fills the hotels; book accommodation early if your dates coincide.
Ephesus, 80 kilometers south of İzmir, is one of the best-preserved ancient cities in the world — the Library of Celsus, the 25,000-seat Great Theatre, the Temple of Hadrian and the colonnaded marble streets are all within a compact walk. In July and August, the site is unbearable: 38°C with ten thousand other visitors. In September, it is warm enough that you need no layers, cool enough that walking does not feel like an ordeal, and quiet enough that the scale of the place — and it is vast — registers without the soundtrack of other people’s audio guides. Fly İzmir with Pegasus — direct connection.
The Lagoon Has Never Looked Like This: Fethiye and Ölüdeniz in September
The Ölüdeniz Blue Lagoon — the UNESCO-protected sheltered bay whose turquoise has appeared in more Turkish tourism campaigns than any other single image — is at its finest in September. The peak-season beach boats that fill it wall to wall in August have thinned considerably. The water, enclosed behind a thin spit of sand, is 27°C and so still that the color is almost impossible to believe from the beach. The paragliders that launch from Babadağ above continue through September, and the 1,960-meter descent to the lagoon is, on a clear September morning, one of the more spectacular things you can do in Türkiye.
The Lycian Way — the 540-kilometer marked coastal trail that runs from Fethiye to Antalya — is nominally walkable at any time of year, but the sections around Fethiye and Ölüdeniz are genuinely excellent in September. The temperature has dropped enough to make multi-hour walking comfortable, the vegetation is still green, and the sea is always within reach. Türkiye’s Top 7 Treks covers the Lycian Way in detail. The Best Places in Kaş covers the destination at the trail’s midpoint. Fly Dalaman with Pegasus — direct connection, 50km to Fethiye.
First of the Season, Best of the Year: Gaziantep at Harvest Time
Gaziantep has been recognized as a UNESCO Creative City of Gastronomy, which is the formal version of what anyone who has eaten there already knows: this is one of the great food cities of the world. In September, it becomes even more specifically itself, because September is when the Antep fıstığı — the pistachio — is harvested. The small, intensely flavored local variety that gives Gaziantep baklava its particular character arrives fresh, and the baklava shops remake their supply from scratch with the season’s first nuts. Eating baklava in Gaziantep in late September, made that week with pistachios picked that month from orchards an hour from the city, is a genuinely different experience from eating baklava anywhere else at any other time.
The Zeugma Mosaic Museum — which holds the largest collection of Roman mosaics in the world, including the haunting Gypsy Girl mosaic that has become the face of ancient Commagene — is cooler and less crowded in September. The copper bazaar, the spice market and the restored Ottoman bedestens of the old city are at their most vivid when the pistachio merchants are in full activity. Fly Gaziantep with Pegasus — direct connection.
The Island That Breathes Again in September: Bozcaada
Bozcaada is a small island in the northern Aegean — 37 square kilometers, a Byzantine and Genoese castle, a harbor of painted wooden fishing boats, windmills on the ridge, and a wine culture that has existed here since antiquity. The Çavuş and Karalahna grape varieties that grow in Bozcaada’s volcanic soil are native to this island and found in almost no other commercial vineyard in the world. In August, the island fills beyond comfortable capacity with day-trippers and weekend visitors from Istanbul. In September, it empties by 60 percent, the Vintage Festival begins, the jazz festival takes over the harbor, and the island returns to the version of itself that makes serious Aegean travelers keep coming back.
The Bozcaada Vintage Festival runs in late September and involves vineyard tours, grape-stomping sessions and tastings that operate more like a village celebration than a tourism product — because Bozcaada is small enough that the festival genuinely involves everyone on the island. The sea at 23°C is still entirely swimmable. The ferry from Çanakkale takes 35 minutes; Çanakkale is connected to Istanbul by overnight bus or, for the Pegasus traveler, the closest airport is Çanakkale via Istanbul. The island is worth the extra effort.
Planning Your September Trip
The short version
Beach + culture: Antalya or Bodrum — direct Pegasus flights, warm sea, the ancient sites empty out.
Pure culture: Istanbul or Ephesus/İzmir — the festivals and the sites both reward September.
Inland food: Gaziantep — pistachio harvest, baklava at its seasonal peak, no sea needed.
Outdoors: Cappadocia or Fethiye — balloon season and the Lycian Way both come into their own.
Off the beaten track: Bozcaada — the island at its quietest, most atmospheric and most itself.
How to book
Use how to find cheap flights to secure September fares early — they are lower than July and August on almost every route but they do not stay low indefinitely. Check the baggage allowance page before packing. Consider the upgrade package for flexibility. Pre-order your in-flight meal via Pegasus Café up to 24 hours before departure. September is waiting.
