Colombia belongs to the intra-tropical climate area of Central and South America. A distinction is made between three climate zones, which are essentially based on altitude (temperature data seen as annual average). The main rainy season is in April/May and from October to the beginning of December. In the tropical rainforest it is the rainy season from November to March.
The hot zone is below about 1,000 m. In this zone the temperatures above 350 m are about 23-30°C, whereas in the hot lower stage (below 350 m) they are about 30°C. The climate of this region is tropical
The temperate zone extends to areas between 1,000 and 2,000 m high. The temperatures that are usually measured in this zone are about 20-23°C.
Above 2,000 m the climate is cool with temperatures between 13 and 17°C. The climate is very cool with temperatures between 13 and 17°C. The temperature in the temperate zone is between 1,000 and 2,000°C. The cities along the Pacific and Atlantic coasts (Buenaventura, Cartagena, Barranquilla, Santa Marta) have a constant climate almost all year round. The average temperature there is 28°C and the humidity is high. Medellín and Cali have a very pleasant climate with average temperatures of 20°C. In the eastern Llanos, in the lowlands and in the rainforest area it is very hot.
Bogotá has an annual average daytime temperature of 19°C. At night the average temperature is 10°C. The humidity in the morning is about 85 percent, at noon about 55-65 percent. Rain is always to be expected, the lowest precipitation falls in the months of January and February.
The best time to travel is in the dry months from December to March. The main holiday season for Colombians is Easter, when hotels and transportation are overcrowded. From July to September there is also travel.
