Istanbul straddles two continents and two seasons at once — the European side tends to be slightly cooler and wetter, while the Asian side gets marginally more sunshine. This creates a city that rewards visitors year-round, though the experience changes dramatically between the sweltering summers and grey, rainy winters.
The golden months are May and September. In May, temperatures settle around 22C, the tulips from April linger in parks, and you can comfortably walk between the Blue Mosque, Hagia Sophia, and Topkapi Palace without melting. September offers warm sea swimming on the Princes' Islands, golden light over the Bosphorus, and summer crowds thinning just enough to make restaurant reservations easier.
July and August bring intense heat — expect 30C+ and relentless sun. The smart strategy is to visit mosques and covered bazaars during midday, then hit rooftop bars and waterfront restaurants in the cooler evenings. Winter (December-February) is genuinely cold and wet, but hotel prices plummet and you'll have the Hagia Sophia practically to yourself. The hammam culture is at its most appealing when it's grey and drizzly outside.
January through mid-March offers the cheapest flights from European cities, often 50-60% less than summer fares. Pegasus and Turkish Airlines run frequent promotions for winter travel.
