Istanbul in summer is vibrant, festival-packed, and at times intense. The Bosphorus shimmers under long days (sunset at 20:30 in July), rooftop bars fill with visitors from every continent, and the city's legendary nightlife reaches its peak. The trade-off: July and August are the hottest and most crowded months of the year. With the right strategy, summer in Istanbul is unforgettable.
