Weather

Peru is a diverse country. With beaches, mountains, rainforest and desert, there is no off-season. But it does pay to know a bit about where you're going, and what you'll need on your Peru tour:

The Andes - Though officially part of the dry season, April and May are considered the Andean spring, while June through October marks the Andean summer. Mid-day temperatures range from 70 to 80 F in the sun. Nighttime temperatures in Cusco range in the 40s F and can dip into the 30s F. Weather is usually clear in the morning with clouds accumulating in the afternoon. Rain can happen in any season, so quality rain gear is essential.
The Amazon - A rainforest environment, the Peruvian Amazon has varied weather conditions and frequent unpredictable rain showers. It is generally hot and humid during the day with more comfortable temperatures through the night. Daytime high temperatures average between 82° and 93° F, and the average nighttime low is between 62° and 73°. Nevertheless, in some areas cold fronts can sweep into the Amazon and push daytime high temperatures down to 50° F and nighttime lows to 43° F. Any time of year, one should always be prepared for cooler temperatures and rain showers. Around 80% of the annual average 79 inches of rainfall occurs during the rainy season (December through March) when heavy rain may continue for hours or days.
The Desert - the Atacama Desert is nearly rainless all year long. Expect hot days and warm nights.
