The climate and weather in Istanbul in 2022 can be defined as four seasons. Sun in the summer, snow in the winter, but the humidity is a constant in sea-encircled Istanbul. Festival-filled spring and autumn are the best times to visit Istanbul, but the chill of the winter is enlivened by magical snowfalls and languid evenings by the Bosphorus is the upside of the humid heat in the summer.

Between December and March Istanbul is cold, grey and blustery. Temperatures average 5C (42F), but humidity and windchill make it feel much colder. Sleet and snow showers are not uncommon; the city is usually buried under several feet of snow at least once every winter – a magical sight, even if it means life grinds to a halt.

Summers can be oppressive; temperatures average 25-30C (78-88F) from June to August, occasionally rising beyond 35C (104F). The heat and humidity can be draining during the day, but when things cool down at sunset city dwellers descend to the Bosphorus to enjoy languid evenings at waterfront cafés.

The best weather is in spring and autumn, when days are temperate and evenings mild. Occasionally, poyraz, a chill Balkan wind, and lodos, hot, humid gusts from the south, can result in a ‘four seasons in a single day’ effect. Both spring and autumn are busy festival seasons.
