If you're wondering about Peru best time to visit, May through September is Peru's dry season and the best window for most travelers, reliable weather in the Andes for Machu Picchu and the Inca Trail, though nights get cold. But "best" really depends on where in Peru you're headed: the Amazon has the opposite dry season, the coast runs warm nearly all year, and if lower prices and thinner crowds matter more to you than guaranteed sunshine, the shoulder months of April, May, September, and October are often the smarter trade-off.
This guide breaks down Peru's weather region by region, tells you exactly when to go for what you actually want to do, and flags the one month (February) when part of the country is genuinely off-limits.
Peru's Three Seasons, at a Glance
| Season | Dates | Best For | Watch Out For |
|---|---|---|---|
| Dry Season | May to September | Trekking (Inca Trail, Salkantay), clear Machu Picchu views | Highest prices, biggest crowds, cold nights in the Andes |
| Shoulder Season | April and October | A balance of good weather, lower prices, and thinner crowds | Some rain still possible, especially early April |
| Wet Season | November to March | Lush landscapes, the lowest prices of the year | Frequent rain, and the Inca Trail closes entirely in February |
For the full month-by-month breakdown specific to the Inca Trail, see our Inca Trail weather by month guide.
Regional Guide: When to Visit Where
Peru isn't one climate, it's three. Plan around whichever region your trip actually centers on.
| Region | Average Temperature | Dry Season | Wet Season |
|---|---|---|---|
| Coast (Lima, Pacific beaches) | 66 to 80°F (19 to 27°C) | December to April | May to November |
| Andean Highlands (Cusco, Sacred Valley) | 59 to 77°F (15 to 25°C) | May to September | October to April |
| Amazon Rainforest | Around 88°F (31°C) | May to September | October to April |
The coast runs opposite to the Andes and Amazon, its dry season is December to April, exactly when the highlands are wettest. If your trip mixes Lima with Cusco, expect genuinely different weather in each place on the same trip. In the Amazon, the dry season is actually best for jungle hikes and wildlife spotting on foot, while the wet season (despite the name) is often prefer by river-based lodges, since higher water levels open up more of the river system by boat.
Andean Highlands and Machu Picchu
May through September is the reliable window for Machu Picchu and the Inca Trail, clear skies and stable trail conditions, at the cost of cold nights and the year's highest prices and crowds. April and October are a strong middle ground. November through March brings real rain and thinner crowds, and February is the one month the Inca Trail closes entirely for maintenance (Machu Picchu itself stays open all year, you just can't hike in via the trail that month).

Best Deals and Travel Packages
| Season | Accommodation | Tour Rates | Airfares |
|---|---|---|---|
| High Season (May to September) | Up to 50% higher | Higher | Higher |
| Low Season (October to April) | Up to 30% lower | Lower | Lower |
If budget matters more than guaranteed dry weather, shoulder and low season is where the real savings are, and it's not a bad trade, the Amazon barely changes weather-wise, the coast is actually warmer, and Machu Picchu itself stays beautiful, just wetter and quieter.
Weather-Related Packing Guide
For the Andes: real layers, since days can be warm and nights near freezing, a waterproof shell regardless of season, strong sun protection (the altitude UV is intense even on cool days), and broken-in hiking boots.
The coast: light, breathable clothing and comfortable walking shoes, it rarely gets cold.
For the Amazon: quick-drying fabrics, strong insect protection, and water-resistant footwear. Everywhere: bring your own toilet paper and hand sanitizer, many public restrooms outside major hotels don't reliably stock either, and pack any altitude-sickness medication before you arrive rather than trying to source it in Cusco.
Peru's Major Festivals
Inti Raymi (June 24), Cusco's ancient Inca sun festival reenactment, one of the biggest events of the year, expect Cusco hotels to book up and prices to spike around this date. Fiestas Patrias (July 28 to 29), Peru's independence day, celebrated nationwide. Semana Santa (Easter week, dates vary by year), major processions especially in Ayacucho and Cusco. All three add both crowds and cost on top of already-peak dry season travel, worth booking well ahead if your dates overlap.
Frequently Asked Questions
What is the best month to visit Peru?
May and September are often calle the sweet spot, both sit in the dry season for reliable Andes weather, but without June through August's peak crowds and highest prices.
What are the best months for Machu Picchu specifically?
April through October, dry season (May to September) for the most reliable clear views, April and October as strong shoulder-season alternatives with fewer crowds.
What is the cheapest month to visit Peru?
November, January, and February tend to be the cheapest, deep in the wet season with the lowest hotel, tour, and airfare prices. Just note February is the one month the Inca Trail itself is closed, see our Inca Trail in February guide for real alternative treks that month.
Is 7 days in Peru enough?
For a focused Cusco, Sacred Valley, and Machu Picchu trip, yes, 7 days is a realistic, comfortable amount of time, enough for a multi-day trek plus a day or two to acclimatize and explore Cusco. If you also want the Amazon, Lake Titicaca, or the coast, you'll want closer to 10 to 14 days to avoid a rushed trip.
Is it safe to visit Peru right now?
Peru's major tourist circuits, Cusco, the Sacred Valley, Machu Picchu, and Lima's main tourist districts, are visited by millions of travelers every year and are generally safe with normal travel precautions. As with any destination, check your home country's current travel advisory before booking, and stick to licensed tour operators and official transport for treks and transfers.
