Do I need to bring cotton-padded clothes to Duku Highway in Xinjiang in mid-June? You need to bring cotton-padded clothes to Duku Highway in Xinjiang in mid-June. In mid-June, I went to Duku Highway in Xinjiang. Because Duku Highway passes through high mountains and valleys, the altitude is high, the climate is cold, and the temperature difference between morning and evening is large, so I need to pay attention to keep warm. Whether you need to bring cotton-padded clothes depends on the weather at that time. The climate in Xinjiang is dry, and the temperature is high during the day, but the temperature will drop sharply at night. It is recommended to bring a light and warm coat or down jacket for emergencies. In addition, you should also pay attention to carrying sunscreen products, sunglasses and other protective products with you to cope with high reflection and strong ultraviolet radiation.
