Winter in Suzhou can be cold, especially in the evenings. We recommend that you pack warm clothing, such as a thick coat, sweaters, long - sleeved shirts, and warm pants. A scarf, hat, and gloves are also essential to keep you warm. Since the weather can be a bit damp, it's a good idea to bring waterproof shoes or boots. During the day, when the sun is out, it might be a bit warmer, so you can layer your clothing accordingly. Also, some of the indoor attractions, like museums, may have central heating, so you can adjust your clothing as needed.
