Spring: March to May
March starts cold and changeable, then April turns milder. The city is known for its tulip festival in April, when parks and gardens fill with millions of flowers. May is one of the best months for strolling the old neighborhoods, riding ferries and visiting the Princes' Islands. Pack a light jacket and a small umbrella, because sudden showers are possible in spring.
Summer: June to August
Summer is the season for warm weather and the sea, with lovely evenings on the Bosphorus. On the other hand, temperatures are higher, the famous sights are more crowded, and hotel prices rise during school holidays. If you travel in summer, do your city sightseeing early in the morning or late in the afternoon and keep the midday hours for rest or shaded places. Day trips to Sapanca and Bursa offer a calmer, greener atmosphere than the city center.

Autumn: September and October
Autumn combines the last of the summer warmth with the calm after the peak: comfortable temperatures and lighter crowds. September is still warm, and October is mild as the rain begins. It is a great season for day trips, and the countryside around Sapanca and Bursa looks its best when the trees change color.
Winter: November to March
Winter is cold and rainy, and it can snow on a few days in January and February, though it usually melts quickly. In return, prices drop and the crowds thin out, and mosques, museums, covered markets such as the Grand Bazaar, restaurants and cafés are excellent options on wet days. If you want lasting snow, most visitors head to Mount Uludağ near Bursa. Bring a warm coat, waterproof shoes and an umbrella.
What to pack
- Spring and autumn: layers, a light jacket, a small umbrella and comfortable walking shoes.
- Summer: light clothing, sunglasses and sunscreen, and comfortable shoes, as the old streets are cobbled and hilly.
- Winter: a warm coat, gloves and a hat, and water-resistant shoes.
How to choose the right dates for your family
If your dates are tied to school holidays, book early, because demand for hotels, transport and tours goes up. If you are flexible, choose May, September or October for the best balance of weather, crowds and price. Either way, we can arrange a program that suits the season, with indoor alternatives for rainy days.
