Best time to visit
Peru’s summer is from December to March, and that’s of course the hottest and wettest time to visit. A better choice is to visit during the Peruvian winter, which is from May to September.
The winters in Peru aren’t cold enough to make a holiday unpleasant – in fact, they’re breezy and warm. The higher you go, the colder it gets, but rarely is it cold enough to make exploration impossible.
