About Istanbul
Istanbul sprawls across the Bosphorus Strait, a city of two continents where Europe and Asia brush against each other. The skyline is a layered postcard: the domes and minarets of Hagia Sophia and the Blue Mosque rise above the Galata Tower, while the Grand Bazaar hums with centuries of trade. Ferries crisscross the water between the Golden Horn and the Sea of Marmara, and the call to prayer drifts over rooftop cafes and teahouses. This is a city of hilly streets, cobblestone alleys, and the constant pulse of 15 million lives.
Under the Köppen classification, Istanbul falls into Csa—hot-summer Mediterranean. Summers are warm and dry, with July and August averaging 28°C, often pushing into low 30s, and humidity lingering near the Bosphorus. Winters are cool and damp: December to February hover around 5–10°C, with frequent rain and occasional sleet. Snowfall is irregular but can surprise the city, grinding traffic on historic hills. Spring and autumn bring mild, pleasant days. Rainfall is spread across the year but peaks in winter, with around 80 rainy days annually. For packing, lightweight cottons and a sun hat for summer, layers and a waterproof jacket for winter—nothing extreme, but humidity makes chill feel sharper.
The best time to visit weather-wise is April to June or September to October, when temperatures are comfortable and the city is less crowded. A notable phenomenon is the *lodos*—a warm, strong southwesterly wind that sweeps in from the Mediterranean, often bringing dust from North Africa and sudden temperature spikes in autumn or early winter. Fog occasionally settles over the Bosphorus in cooler months, creating a moody atmosphere. Snow is rare but memorable, dusting the minarets and hills roughly once or twice a year. Summer heatwaves can be intense, but the sea breeze offers some relief.
