In midsummer, from mid-June to mid-September, you’ll need lightweight cotton summer clothes and a light sweater or jacket for evenings or to wear on the Central Anatolian Plateau. You won’t need rain gear at all; expect it on the Black Sea coast. You’re better off hiding between showers than carrying rain gear for the entire trip just for a day or two of possible rain on the Black Sea coast. In spring and autumn, summer clothes will still be fine, but evenings will be cooler. If you plan to travel extensively in Central Anatolia (Ankara, Konya, Cappadocia, Nemrut Dağı), pack a thicker sweater and perhaps a light raincoat. In winter, from December to March, you should wear woolen rain gear. Although it is not really cold along the Mediterranean coast, it is cold, wet and rainy in most of the southern countries, but central Anatolia, the northern coast of Turkey including Istanbul is cold, even sometimes covered in snow in winter.

Dress code for entering the mosque: During the summer, women and men can wear casual shirts, t-shirts, shorts, or tights throughout Turkey, but you have the rules for entering mosques; long pants and skirts, long-sleeved shirts, and scarves for women. Even if the mosque administration provides you with the necessary coverings, it is best to have them with you to avoid the queues and wait.
