Alanya in September: Weather & What to Expect
Share
If you love proper summer warmth but could do without the August crush, September might be Alanya's best beach month of all. The days stay hot at around 30°C, the sea is at its warmest — about 27°C — and yet the peak-season crowds start thinning out as the school holidays end. You get full-blown Mediterranean summer with a little more room to breathe. Here's what to expect.

The warmest sea of the year
Here's September's trump card: the Mediterranean has spent all summer warming up, so the sea is now at its warmest, around 27°C — gloriously swimmable and bath-like. It's superb for swimming, snorkelling and water sports, and arguably more comfortable than the air on a hot afternoon. For the full picture, see sea temperature in Alanya.
Still hot — plan around it
September stays genuinely hot, particularly in the first half, with daytime highs around 30°C and warm, balmy evenings near 21°C — you'll be in summer clothes day and night. The sun remains strong, so the usual heat sense applies: shade in the middle of the day, plenty of water, and good sun protection. See staying safe in the Alanya sun.
Crowds easing, value improving
As the European school holidays wrap up, the busiest weeks pass and September feels a touch calmer than August — a bit more space on the beach, slightly easier prices, while still buzzing and fully open. It's the classic "summer holiday without the peak madness" month, popular with couples and anyone without school-age children. See the best time to visit Alanya.
Will it rain?
Rarely. September is still well within the dry season, so you can expect long sunny days with little rain, especially earlier in the month. The chance of a shower creeps up slightly towards October, but washout days are unlikely.
What to pack for September
- Summer clothes & swimwear — it's hot day and night.
- Strong sun protection — high-SPF cream, hat, sunglasses; the sun's still fierce.
- Light evening wear — you'll rarely need more than a light layer, if that.
- Insect repellent — still mosquito season; see mosquitoes & bites.
