Peru's seasons are the reverse of those in the northern hemisphere. Summer in Peru is from December to February and winter from July to September. There's not a bad time to visit Peru, however as a very general recommendation the best time to visit the coast is during the summer (Dec-Feb) and the best time to visit the mountains is in the winter (Jul-Sept). The jungle is hot and steamy all year round with heavy rains in December and January.

Peru is divided up into three distinct geographical regions:
the coast, the mountain highlands and the jungle.
Mid April – October. This period is the dry season, with hot, dry days and cold, dry nights, often hovering just above freezing, particularly in June and July. May is perhaps the best month with the countryside exceptionally lush, yet with superb views and fine weather. You’ll find the flowers in full bloom, the grass green and the streams full. Peru’s high season is from June to August which coincides with the dry season and summer holidays in North America and Europe. You’ll find Cusco a pretty cosmopolitan city with tourists from all over the globe converging on Machu Picchu.
November – Mid April This is the wet season with most rain in January and February. It’s usually clear and dry most mornings with outbursts of heavy rain in the afternoons. The daily temperatures are typically mild with only a small drop at night.
The Inca Trail is much less crowded during this period and there’s a more abundant fresh water supply, but of course be well equipped for the rain. You’ll also find some roads may become impassable particularly when trying to visit villages off the beaten track. Many of Peru’s major festivals such as Carnival and Easter Week take place during this period.
December – April This is summertime on the coast where the weather is hot and dry and ideal for swimming and getting a tan. Temperatures on average range from 25 – 35°C. There is little or no rain during these months. The beaches around Lima and the North can packed during the months of January and February which coincide with school holidays.
May – November From May to November the temperature drops a bit and you’ll find blankets of sea mist engulfing the coast from the south right up to about 200 km north of Lima. At this time of year only the northern beaches such as Mancora and Punta Sal are warm enough to provide pleasant swimming.
April – October This is the ‘dry’ season with daily temperatures averaging 30–35°C. However cold fronts from the South Atlantic are common when the temperatures can drop to 15°C during the day and 13°C at night.
The dry season is the best time to visit the jungle regions … there are fewer mosquitoes and the rivers are low, exposing the beaches. It’s also a good time to see nesting and to view the animals at close range, as they stay close to the rivers and are more easily seen.
November – March This is the wet season, hot and humid, when you can expect heavy rain at anytime. It only rains for a few hours at a time, so it’s not enough to spoil your trip. Wellington boots are a must though, as some of the jungle trails can become small rivers.
All countries require a valid passport (with minimum 6 months validity). Citizens from most countries in the Americas and Western Europe do not require visas to enter Peru. Bolivians, Ecuadorians, Brazilians, and Chileans may enter determined regions of the country just by presenting their national identification documents. The maximum authorized length of stay is 90 days.
To remain longer in the country or to enter for other purposes (residence, study, research, work, etc.), you must request the corresponding visa at the Peruvian consulate of your country of residence before traveling.
Contact your embassy, or consulate for the most up-to-date visa requirements. It's your responsibility to have the correct travel documentation.
No inoculations are currently required for Peru. However you should consider immunization against the following:If you plan on going into the Peruvian jungle (Iquitos, Manu, Tambopata) then a yellow fever vaccination is recommended. There are still the occasional outbreaks and it is frequently obligatory to show a vaccination certificate when entering the jungle regions. If you don't have a certificate then you will be inoculated on the spot as you get off the plane!
Malaria tablets are also recommended for the jungle, although nearly all of the jungle lodges in the Madre de Dios/Tambopata areas and Manu National Park state that there have been no reported cases of malaria, and that taking anti-malaria tablets are optional but recommended.
To avoid any problems on your trip, take into account the following general recommendations:Daily departures - Price per person based on shared service unless otherwise requested and subject to change without prior notice and availability - International airfare is not included.
