Istanbul winter weather (and what to bring)
The winter weather in Istanbul is unpredictable and changeable. A clear, sunny morning can easily turn to rain or even snow by evening. Temperatures average around +10 °C during the day, although on cold days it can be +3...+5 °C. Heavy frosts and stable snow cover are very rare: it sometimes snows in January-February, but usually melts quickly within a day. At the same time, the winter chill is felt due to the damp, penetrating wind from the Bosphorus (called poyraz) - you can't do without a warm jacket, scarf and hat in Istanbul in winter.
Take comfortable waterproof shoes onyour trip and consider layered clothing. In a warm afternoon, you can always remove an extra layer, and in a damp wind - put on a scarf or jacket. An umbrella will also come in handy (if you forget - an inexpensive umbrella can easily be bought locally from street vendors). The Mediterranean climate makes winter in Istanbul mild: from time to time there are dry sunny days, when citizens fill the embankments and parks, enjoying the rare winter sun. On such days it is especially nice to have a traditional Turkish breakfast on the terrace overlooking the Bosphorus, warmed by a cup of hot tea or coffee.
What to wear in Istanbul in winter? In winter you need about the same clothes as in late fall in the middle part of Europe. Comfortable jeans or pants, a warm sweater, a windbreaker and a thick jacket or a light down jacket are perfect. Choose shoes without heels, on non-slip soles - you will have to walk a lot on city streets. In Istanbul, it is customary to dress for the weather and quite discreetly, especially when visiting mosques (women should cover their heads and shoulders, and men should not be in shorts).
