In October, Istanbul experiences the full embrace of autumn, with temperatures gradually cooling down and an increase in rainfall to around 42mm. This change in weather adds a vibrant touch to the city's diverse landscape as the fall greenery paints Istanbul in a beautiful array of rich colors. Despite being one of the windier months, the city retains a calm and charming atmosphere. The sun continues to shine for a significant portion of the day, offering ample time for sightseeing. As the sun sets earlier, there's a pleasant nip in the air, enhancing the twilight experience.


October is a mildly cool month in the word’s every meaning but keep that in mind, Istanbul’s weather is always more pleasant than European capitals. The first 3-4 days of this October will be even cooler so prepare yourself. The average high temperature in October drops to a comfortable 19.4°C (67.9F°), with nights averaging a mild 15.5°C (59.9F°). The relative humidity stands at around 73%, and there are typically 12.5 days of rainfall during the month, accumulating around 42mm (1.65 inches) of precipitation.

Snowfall is not expected in Istanbul during this period, it is not that cold! The sea temperature is 18.4°C (65.1F°), making it less suitable for swimming. Daylight hours decrease slightly, with an average of 11 hours and 7 minutes of daylight in Istanbul during October. The city enjoys an average of 7.7 hours of sunshine per day, and the UV index registers at 4, indicating a moderate threat to health from the Sun's UV rays, so it's advisable to take precautions when exposed to the sun, such as using sunscreen and protective clothing.

What to Pack for Istanbul in October 2025?

So you decided to visit Istanbul this month! What a great idea! But keep in mind that packing for Istanbul in October requires some careful consideration, as the weather begins to transition from warm to cooler temperatures. Here's a handy list of items to ensure you're prepared for you to have an amazing trip:

Layers of Clothing: Since the weather can be unpredictable, it's wise to pack layers. Bring lightweight long-sleeved shirts and sweaters for cool mornings and evenings, but also include short-sleeved shirts for milder days. Carry a jacket all the time with you.

Comfortable Shoes: Istanbul is a city made for exploring on foot, so comfortable walking shoes are a must. Consider waterproof options in case of rain. You may consider bringing two different sneakers or you can buy great shoes at bargain prices in Istanbul.

Light Jacket or Cardigan: A light jacket or cardigan will come in handy for cooler evenings. Opt for something that can easily be added or removed.


Umbrella: October sees an increase in rainfall, so a compact umbrella can be a valuable addition to your packing list. But keep in mind that, when it rains, the streets of Istanbul will be filled with umbrella sellers right away so actually you don’t need to carry an umbrella all the way.

Raincoat or Waterproof Jacket: If you prefer a more all-weather option, a waterproof jacket can keep you dry during Istanbul's occasional rain showers. Be sure that your jacket is certainly waterproof so you won’t be soaked in rain if it rains cats and dogs -it can happen in October.

Hat and Sunglasses: During sunny days, a hat and sunglasses will protect you from the sun's rays. Since there are some warnings about the UV lights in October, it is a smart idea to keep yourself careful.

Power / Travel Adapter: Don't forget a universal power adapter to keep your devices charged but don’t panic if you forget also. Istanbul, especially the old town, has many shops where you can find any adaptor you find easily. In Turkey, Types C and F sockets are used with a voltage of 230 volts and a frequency of 50 Hz.

Istanbul Tourist Pass®: Don't forget to download the App for your Istanbul Tourist Pass® and start your journey right away! The App is an easy way to access a multitude of attractions and services conveniently.

By packing smartly and considering the weather conditions, you'll be well-prepared to enjoy your Istanbul adventure in October.
