If you ask "when's the best time to visit Peru," the honest answer is: it depends which Peru you mean. The Andes highlands around Cusco and Machu Picchu, the desert coast around Lima, and the Amazon rainforest in the east all run on completely different seasonal clocks — sometimes in opposite directions. Understanding that is the difference between a trip that lines up perfectly and one that gets rained out at the wrong moment.
Below is how we plan trips for our own travelers, region by region, plus the festivals and holidays worth building your dates around.
Peru's Two Main Seasons
For most travelers — especially anyone trekking the Inca Trail, Salkantay, or visiting Machu Picchu and the Sacred Valley — Peru really only has two seasons that matter:
Dry Season
Clear skies, minimal rain, and the classic postcard views of Machu Picchu. This is peak trekking season and also the busiest and most expensive time to visit — book Inca Trail permits well in advance.
Wet Season
Warmer overall, greener landscapes, but more rain — especially January through March. The classic Inca Trail closes entirely every February for trail maintenance and conservation.
Shoulder months — April, May, September and October — are often the sweet spot: fewer crowds and lower prices than peak season, with weather that's usually still cooperative.
Weather by Region
Because Peru spans desert coast, high Andes and Amazon basin within a few hours of each other, "good weather" means something different depending on where you're headed.
Andes Highlands
Dry, sunny days and cold nights May–Sept (down to freezing at altitude). Oct–April brings afternoon rain but warmer temperatures overall. Altitude (11,150 ft / 3,400 m in Cusco) matters more than the calendar — plan a day or two to acclimatize regardless of season.
Desert Coast
Runs opposite to the highlands. May–November brings "garúa" — cool, grey, overcast skies with little rain but limited sun. December–April is warm, sunny beach weather. If you want sunshine in Lima, that's your window.
Amazon Rainforest
Warm and humid year-round (24–32°C). June–September is the drier season with easier trails and lower river levels. December–March is wetter and more humid, but the rainforest is at its lushest and most alive.
Quick Month-by-Month Guide
| Months | Highlands (Cusco/Machu Picchu) | Notes |
|---|---|---|
| Jun – Aug | Peak dry season, coldest nights | Busiest & most expensive; book permits early |
| May, Sep | Dry, fewer crowds | Best overall value — our top recommendation |
| Oct, Nov | Light rain increasing | Good shoulder season, greener scenery |
| Dec, Mar | Warmer, rain likely | Lower prices, pack a rain layer |
| Jan | Rainy season peak | Lush landscapes, fewer tourists |
| Feb | Wettest month | Classic Inca Trail closed for maintenance |
| Apr | Rain tapering off | Underrated shoulder month, good value |
Holidays & Festivals Worth Planning Around
A handful of dates on the Peruvian calendar are worth knowing about — some because they're spectacular to witness, others because hotels and transport book out well in advance.
-
Inti Raymi — Festival of the Sun
June 24, Cusco
One of the largest Inca festivals still celebrated, with a huge reenactment at Sacsayhuamán. Spectacular to see, but Cusco hotels sell out weeks ahead — book early if your trip lands nearby.
-
Fiestas Patrias — Independence Day
July 28–29, Nationwide
Peru's biggest national holiday. Expect parades, some closures, and heavier domestic travel — plan transport and accommodation ahead of these dates.
-
Semana Santa — Holy Week
Late March / April, varies by year
Processions and religious events nationwide, especially striking in Ayacucho and Cusco. Some transport schedules shift around Easter weekend.
-
Q'oyllur Rit'i
Late May / early June, varies by year
A remarkable Andean pilgrimage near Ausangate, blending Inca and Catholic tradition. Logistically involved to attend, but unforgettable if it fits your dates.
-
Carnival
February, varies by year
Water balloons and water fights are a real tradition in the streets, especially around Cusco — fun to experience, just expect to get wet if you're out walking.
-
New Year's Eve & Day
December 31 – January 1
Falls in the wet season, but a lively time to be in Cusco or Lima if your trip lines up with it.
Getting the Timing Right for Trekking
If a multi-day trek is the centerpiece of your trip — Inca Trail, Salkantay, Choquequirao, Lares — a few practical points matter more than the general seasons above:
Book Inca Trail permits early. Peru issues a limited number of Inca Trail permits per day, and July and August routinely sell out 4–6 months ahead. If your trip lands in peak season, lock in permits as early as you can.
February is a hard stop for the classic trail. The government closes the Inca Trail entirely every February for maintenance and environmental recovery. Alternative treks like Salkantay and Lares stay open year-round, weather permitting.
Shoulder season is underrated. May, June and September consistently give the best combination of dry weather, manageable crowds and reasonable pricing — it's what we recommend to most first-time travelers.
