City Life & Weather

September is the start of Autumn in Istanbul, a superb month after a very hot summer season, and with an average temperature of 25°C and precipitation 64 mm. The early September can still be hot and muggy, but it starts to cool down after the first week and it becomes very ideal for strolling and exploring the city on foot.

September is a great time to visit Istanbul, as the city experiences mild, comfortable weather. Temperatures typically range from 25°C (77°F) to 19°C (66°F), offering warm days and cooler evenings.

Early in the month, you can still enjoy beach weather, while later in September, the climate becomes milder, making it perfect for exploring Istanbul’s outdoor attractions.

• Daytime: Warm and pleasant, great for sightseeing.
• Evenings: Cooler, requiring a light jacket or sweater.
• Rain: Expect only 2-3 rainy days, so outdoor activities remain mostly unaffected.

The weather can become unpredictable that while one week is sunny, it can be rainy with thunderstorms.

The city is less crowded with locals due the school fervor of the parents. We recommend you to bring shorts, dresses, t-shirts for warm afternoons, long pants for cooler nights and light coat and portable umbrella in case of rainfalls.

The days are more shorter than in August, the sun set around 19:25.

For visitors, packing light clothing for the daytime and layers for the cooler evenings is ideal. Sunscreen is still necessary, especially for those planning to spend extended time outdoors.
