Packing for your trip will depend upon the time of year you choose to visit Istanbul. Temperatures range from the mid-40’s (Fahrenheit) in the winter months of January and February to a warm 75 degrees in July, the warmest month. If your planning on a summer visit, be sure to go heavy on light cotton ensembles and bring along a pair of good walking shoes as the majority of attractions in the area require a good deal of walking.
While the days are relatively mild in the winter months of December through January, the nights can dip into the 40’s and below. Make sure to pack a heavier jacket and layer your clothing with sweaters. January is the wettest month, making bringing along an umbrella an excellent idea.
