Peru Weather in May

Given Peru’s three distinct climate zones, you should expect weather conditions to change depending on the region you are visiting. However, May is a warm month in most parts of the country.
The capital city of Lima, situated in a coastal desert strip, sees average highs of 22° C and lows of 16° C. Meanwhile, if you are traveling to the Amazon, expect warm and humid weather conditions with high chances of rainfall. Temperatures in the rainforest can range anywhere between 31°C to 22°C. Further down south, the Andes has a cooler climate.
However, while traveling to Machu Picchu, wandering around Huaraz, or boating in Lake Titicaca, one must take note of varying temperatures in the Peruvian Andes. The mercury in these regions during May can soar as high as 30°C during the day and plummet to 6°C at night.

Why Visit Peru in May

The ocean may still be a little chilly for swimming, but you can enjoy lovely beach walks and a thriving nightlife in these areas.
- Fewer crowds: Tourist numbers in Peru take off in July and the country is crowded until September. This makes May an ideal month for those who want to avoid crowds. With attractions and tourist spots seeing less foot traffic, your chances of getting picture-perfect photos are high.
- Better rates: Given that the peak season is yet to start in the South American country, you can book hotels and flights at a better rate if you are planning to visit Peru in May.

Where to go and what to do


You can find an abundance of activities in Peru in May. Get under the skin of Lima as you learn more about its history and heritage. Walking around the historic center is an excellent way to get acquainted with the country's past. As May is a relatively quiet month, you can tick off the city’s highlights without having to deal with crowds. The trails around Machu Picchu are long and strenuous. It takes about four days to hike the Inca Trail. Therefore, you need the weather on your side to tackle them.

The high Andes to the northwest of Arequipa is famous for the impressive Cotahuasi Canyon. This natural attraction is one of the deepest canyons in the world. May is an excellent time to explore this incredible sight. The other highlight you might want to add to your itinerary is Paracas National Reserve. Clear skies and lots of sunshine mean that you can explore this national park located near Pisco on the south coast without having to worry about rain. Although it may be too cold to swim in the sea at this time of year, the weather is ideal for walking through its dunes and along its cliffs.
A Peru trip is incomplete without a visit to Lake Titicaca. The lake looks gorgeous in May with a bright sky, lush greenery, and abundant wildlife everywhere. Make sure to include this destination in your itinerary if you are heading for Peru during this time of year.
What to bring

Although rain is not common in May, you might as well carry a raincoat and a waterproof jacket, just in case a scattered shower muddles your travel plans. High-quality hiking boots are a must whether you are attempting the 26-mile Inca Trail or a shorter trek. You can manage with light trousers and t-shirts during the daytime. However, nights can be pretty cold, especially in the Andes. Make sure that you carry some warm clothes along with you.
