Peru Weather & Climate: Monthly Averages

Peru's diverse geography leads to varied climates across its regions. While the coast might enjoy warm days, the mountains could be gripped by cold, and entirely different weather conditions prevail in the jungle.

Regional Differences

Along the coast, winter extends from June to September . During these months, the mountainous areas often enjoy sunny and warm days but experience cold nights. In the Amazon region of Peru and the lower areas east of the Andes, daytime temperatures remain fairly consistent throughout the year, ranging from 30°C (86°F) to 33°C (91°F). The high humidity however can make it feel even warmer. During the 'dry months', especially in July and August, maximum temperatures can climb slightly higher.

Mountain Climate

In the Andes mountains the temperature is mainly determined by the altitude. In the valleys, the average annual temperature typically lies between 15°C (59°F) and 20°C (68°F). However, the upper peaks can dip below freezing. Generally, temperatures are lower west of the Andes compared to the east.

Tropical Climate

Places like Tumbes and Piura have tropical climates. From December to April, the mountains and jungle experience heavy rains. In contrast, Lima and much of the coast receive little to no rain.

Best time to visit

If you're planning a visit, the best time for the Peruvian coast is from November to April, where sunny days and pleasant temperatures await. For the Andes, the best travel window is from May to October.

Given the diversity in climate, it's advisable to check the weather forecasts and climate data for specific destinations in Peru before planning your trip.
