In this part of Peru, located in the eyebrow of the jungle, the climate is subtropical highland but ever humid, described by the Köppen climate classification as Cfb, with an average temperature of 18 °C and an average relative humidity of 74 percent. However, in some areas the temperature can drop to 2 °C. Chachapoyas has a temperate climate and is moderately rainy. The annual average of maximum and minimum temperature (period 1960-1991) is 19.8 °C and 9.2 °C, respectively. Annual average precipitation accumulated for period 1960-1991 is 777.8 mm.
Jiron Triunfo is the street which links the three principal plazas of the city. It is called by this name because the victorious Chachapoyans of the Higos Urco battle entered the city through here. Chacapoyas’ transitional location between the arid Cordillera Occidental and Cordillera Central and the rainy, rainforested Cordillera Oriental, allow it to receive a generally moderate annual precipitation amount without receiving the copiously excessive, tropical-rainforest-like precipitation amounts farther east in towns such as Moyobamba.
