Best Time To Visit Istanbul > Weather, Temperature & Season

What is the best time to visit Istanbul?

The best time to visit Istanbul is from March to November, when the city enjoys its most favorable weather and a vibrant cultural calendar. Temperatures during this period range from 10°C to 29°C, offering mild springs, warm summers, and pleasantly cool autumns. Spring (March to May) and autumn (September to November) are particularly ideal with fewer crowds and comfortable weather, while June to August is great for outdoor festivals despite higher humidity. Winters (December to February) are quieter, colder, and wetter, offering budget-friendly travel and cozy indoor experiences.

June to August (Peak Season - Summer): Summer is peak tourist season in Istanbul, with daytime temperatures averaging between 25°C and 29°C. The skies stay mostly clear and rainfall is minimal—only about three rainy days per month. July and August are the driest months. However, humidity can be high, and popular attractions often have long queues. Locals tend to leave the city during August, especially around Kurban Bayramı, while tourists fill Istanbul’s lively neighborhoods. Expect higher hotel prices and busier restaurants during this time.

March to May & September to November (Shoulder Season - Spring/Autumn): Spring and autumn are the best times to explore Istanbul’s historical and cultural richness without the summer heat or winter gloom. In Spring, from March to May, April, in particular, is a visual delight during the Tulip Festival. September to November brings similar advantages. With temperatures ranging from 12°C to 25°C, it’s still warm enough. While rain begins to increase in November, the city still sees plenty of good days for sightseeing, and the crowds remain manageable.

December to February (Off Season - Winter): Winter in Istanbul is off-season, marked by colder temperatures and increased rainfall. Daytime highs average 7°C to 12°C, while nights can dip to 3°C. Snowfall is possible, especially in January, but tends to be light and short-lived. Rainfall peaks in December, averaging over 100 mm, and skies are often grey. That said, this is the most budget-friendly time to visit, with hotel and flight deals widely available.
