October brings a gentler side of Istanbul: crisp days, thinner crowds, and the warm tones of Ottoman tiles matching fall leaves. Major sights like Hagia Sophia and Topkapı feel more accessible, especially on weekday mornings. Stroll the Bosphorus, sip strong tea in shadowy courtyards, and catch fireworks on Republic Day. Even with a few gray days, Istanbul in October is ideal for layering up and slowing down.
