Istanbul is known for its humid summers and Mediterranean climate. However, there are many variances in Istanbul weather, and visitors may experience very different conditions depending on the time of year.
What to expect from Istanbul’s weather
Typically, Istanbul enjoys blistering temperatures in the summer, with highs of around 30 degrees Celsius and lows rarely dropping below 20 degrees. June, July and August are relatively dry months too, meaning the weather in summer is ripe for welcoming travellers.
Nevertheless, the huge size of Istanbul means various sections of the city may see very different kinds of weather. Outside the city centre, fog is common and can regularly descend in autumn and winter. Autumn and spring may be wet and windy, meaning temperatures can fluctuate widely.
In general, Istanbul’s weather remains humid all year-round and, although rainfall is uncommon in the summer, thunderstorms happen more regularly over this period. Temperatures in winter are quite chilly too, with lows of around four degrees Celsius in January and February, and the chance of occasional snow showers.
When to visit Istanbul
The reliable warmth and general dryness of summer makes it the most popular time to visit Istanbul. To avoid the sweltering summer heat, try visiting in late spring or early autumn instead, when temperatures are cooler but wetter and more blustery.
For a winter holiday with a difference, choose a Christmas break in Istanbul. There are few more romantic sights in the city that seeing it covered with snow, and its cold crisp days are relished by travellers who revel in winter weather.
