Peru: When to Go

Peru's climate can be divided into two seasons - wet and dry - though this can vary depending on the region. Temperature is mostly influenced by elevation: the higher you climb, the cooler it becomes.

Peru's peak tourist season is from June to August, which is the dry season in the Andean highlands. It's also the best time to go if you're interested in hiking or mountain climbing. While travelers visit the highlands year-round, the wettest months, December to March, make trekking a muddy proposition. Many of the major fiestas occur around this time and continue undiminished in spite of heavy rain.

On the coast, Peruvians visit the beach during the sunny, humid months from late December through March. The rest of the year, the coast is clothed in mist. In the eastern rain forests, it naturally rains a lot. The wettest months are December to May, but travelers visit year-round; it rarely rains for more than a few hours at a time and there's plenty of sunshine to enjoy.

Weather

The coastal region of Peru is cool for its latitude, and quite dry year-round. Temperatures are warmest during the summer months (January to March), with hot and humid days of around 29°C (84°F) and cool nights of just below 20°C (68°F). Winters are not too cold, but frequent low cloud may cause some to pine for sunshine. Inland, the temperature drops substantially, with less seasonal variation during the day - average highs are about 21°C (70°F) throughout the year and winter nights are chilly, particularly at higher elevations. There is also a moderate wet season here from December until May.
