The climate is tropical along coast and eastern plains; cold in the highlands; periodic droughts. Colombia is an equatorial country, so there are no seasons in the common sense of the word. Temperatures do not vary much throughout the year. What Colombians normally refer to as the winter is the rainy season. Cities such as Bogotá, Tunja, and Pasto have been known to reach temperatures under 0 degrees Celsius, so if you are sensitive to cold weather be prepared.
