Best time to visit Istanbul

Mid-April to early June and September to October

Istanbul is at its finest in spring and autumn, when mild sunshine suits long walks between mosques, bazaars and Bosphorus ferries, though these are also the busiest and priciest months. Summer is hot, humid and crowded but lively, with rooftop bars, open-air concerts and swimming on the Princes' Islands. Winter is grey, damp and sometimes snowy, yet it brings the lowest prices, short queues and the city at its most local.
