When to go to Peru by location
Amazon
Perennially hot and humid, the jungle areas east of the Andes nonetheless have distinct seasons- a dry season between May and October, and a wet season between November and April, when the rivers swell following frequent rain showers. Iquitos lends itself more to year-round travel, being closer to the equator, whilst Manu and Tambopata are far more favourable to visit in the dry season, when you can witness monkeys, birds, caimans, and small mammals. In Iquitos, animals can be easily spotted along the mud banks between June and September, once river levels recede.
Andean Highlands
Most visitors to Peru will incorporate the obvious charms of the Andean Highlands of Peru and the optimum time to trek amidst the beautiful Andean scenery of this region is between May and October, when the days can be clear and warm with somewhat chilly evenings, with temperatures reaching 20°C-25°C, or 68°F to 77°F in the daytime. This is Peru’s high season, and visitor numbers can be high. This is of particular note to those looking to trek the spectacular scenery of the Inca Trail to Machu Picchu, which we recommend booking at least 6 months in advance to secure space. Outside of these months you may experience rain, but there will be fewer tourists, more verdant vegetation and flora, including orchids at Machu Picchu.
Coast
Between November and April the coastal regions are bathed in sunshine. The further north you go, the longer this summer weather lasts, with places like Mancora in the far north enjoying good weather well into Peru’s winter. Further south, including the areas around Lima, May to October and Peru’s winter months bring cloud and a much cooler climate.
