The Andean weather can be unpredictable, despite the sharp divide between dry and wet seasons. The dry season runs from May to October or November; the rainy season goes from December through April. Nevertheless, Choquequirao lies in the forested fringes of the Amazon basin, where showers can occur at any time of year. Therefore, even in the “dry” season, your daypack should always include full rain gear (both jacket AND trousers).
Daytime temperatures can vary greatly, with daytime highs ranging from 10ºC/50ºF to 32ºC/90ºF and nightime lows ranging from 10ºC/50ºF to a cold 4ºC/40ºF, though seldom much lower. The floor of the Apurimac Canyon gets very hot during the day. Bring your swimsuit for a delicious dip in the river.
