The Best Time to Visit Peru (Month-by-Month, 2026)

Peru is not one climate. It is three, and they run on incompatible calendars. Getting this straight before you book anything saves a lot of re-planning.

The Andes — Cusco, the Sacred Valley, Machu Picchu, Lake Titicaca, the Colca Canyon — run a classic highland dry-wet split. Dry season is May through September: sunny days at 18-22°C, cold nights that can drop below freezing above 3,500m, and reliable trail conditions. Wet season is December through March: afternoon rain most days, muddy trails, landslide risk on rural roads, and the Inca Trail shutdown every February. April, October and November are shoulder months — cheaper, quieter, more weather variable.

The Amazon basin — Puerto Maldonado, Tambopata, Manu, Iquitos — flips it. Wet season runs November to April with daily rain, high water levels and boat access to flooded forest. Dry season is May to October with lower rivers, exposed trails and better terrestrial wildlife viewing. Neither season is objectively better; they offer different experiences, covered in section four.

The Pacific coast — Lima, Paracas, Nazca, northern beaches — inverts the Andean pattern. May to September is garua season: persistent grey coastal fog, 16-19°C days in Lima, no rain but almost no sun. December to March is coastal summer: blue skies, 26-29°C days, busy beaches from Punta Hermosa to Mancora. Lima feels like a different city between July and January.

Peak Machu Picchu travel sits in May-September, so most Peru itineraries accept the garua Lima weather as a trade.

January: Cusco 20°C days, heavy afternoon rain, trails muddy. Lima 26-29°C, sunny, beach season peak. Iquitos 30°C and wet. Cusco tour prices low, crowds thin.

February: Cusco wettest month, 120-150mm rainfall. Inca Trail closed all month for maintenance. Machu Picchu open but access via train only. Lima still sunny and warm. Cheapest highland tour pricing of the year.

March: Cusco still wet early, drying late. Lima finishing beach season. Shoulder pricing, low crowds. Good value if you accept rain risk.

April: Cusco transition month, 18-20°C days, rain tapering. Trails drying out. Lima garua starting. Tour prices begin climbing mid-month. Semana Santa (Easter) busy in Cusco.

May: Dry season opens properly. Cusco 20°C days, clear skies, cold nights. Amazon water levels dropping. Lima garua settling in. Peak-season pricing starts.

June: Cusco peak dry, 20-22°C days, near-zero rain, cold nights at 0-2°C. Inti Raymi 24 June 2026 fills Cusco — book hotels 6+ months ahead. Highest tour-price band of the year.

July: Cusco busiest month. Dry, sunny, crowded. European and US summer holidays land here. Peak pricing continues. Amazon dry and walkable.

August: Mirror of July. Slightly more wind in the highlands. Peak crowds, peak prices.

September: Dry season continues, crowds thinning, prices easing 10-15% from July-August peak. Strong value month.

October: Shoulder. Cusco 20°C, occasional showers late month. Lima garua lifting. Prices below peak. Underrated month.

November: Wet season returning to Cusco. Amazon water rising. Lima warming up. Low-season pricing returns.

December: Full wet season in the Andes. Christmas and New Year in Cusco quietly busy with domestic travellers. Lima in full summer.

The classic 4-day Inca Trail is permit-controlled. Peru's Ministry of Culture releases 500 permits per day, of which roughly 200 go to trekkers and the remainder to guides, porters and cooks. Permits are non-transferable, tied to your passport number, and cannot be resold.

For peak dry season — May through September — permits sell out 5 to 7 months in advance. June and July dates often gone by January of the same year. If your dates are fixed and fall in peak season, book the moment permits release for the next year, which is typically October of the prior year.

Shoulder-month permits (April, October, November) are easier, usually available 2-3 months out. December and January still have permits close to the date but trail conditions are wet and muddy.

February: the Inca Trail closes completely. Every year, no exceptions. The trail gets heavy maintenance work and the rains make sections genuinely dangerous. Machu Picchu itself stays open, reached by train from Cusco or Ollantaytambo.

The main alternative is the Salkantay trek — 4 to 5 days, higher altitude, no permit cap, runs year-round including February. Many travellers who cannot secure Inca Trail permits end up preferring Salkantay for the scenery (21,000ft Salkantay peak, turquoise Humantay Lake) and the smaller crowds. Lares, Choquequirao and the Inca Jungle route are other permit-free options.

If Inca Trail is the specific goal, lock dates 6+ months out and accept there is no same-year flexibility for June-August.

Amazon timing confuses travellers because the obvious logic — dry is good, wet is bad — does not apply. Both seasons are valid; they are just different trips.

Dry season (May to October): river levels drop 5-8 metres in Tambopata and Manu. Trails that are underwater in wet season become walkable. Clay licks where macaws and parrots gather are most active. Jaguar and giant otter sightings peak on exposed sandbars. Mosquito numbers are lower. Hiking-heavy itineraries work. Sunny mornings, scattered afternoon showers. This is when most first-time Amazon visitors go, and it pairs cleanly with a Cusco dry-season trip.

Wet season (November to April): water rises and floods vast areas of forest. Canoe access opens up sections that are inaccessible on foot in dry months. You glide between the trunks of standing trees. Fishing-based itineraries (piranha, peacock bass) are strongest. Dolphin sightings in flooded channels are common. Fruit trees are in season, which concentrates monkeys, sloths and birds. Rain is predictable — usually an hour or two in the late afternoon, not all day.

Iquitos and the northern Amazon (Pacaya-Samiria reserve) run this pattern more extremely because the river network is larger. A flooded-forest trip in January-March from Iquitos is a legitimately different experience to a May-September Tambopata hike.

Combining Amazon with Cusco: May, June and September are the cleanest overlaps. Dry in both. If you want the flooded-forest version, plan a coast-and-jungle trip without the Andes, or accept wet trails in Cusco.

Nearly all international flights into Peru route through Lima (LIM), Jorge Chavez International. A new terminal opened in 2025 and the airport now handles wider-body long-haul schedules. LATAM dominates — it is effectively the Peru national carrier — with Avianca, Copa, American, Delta, United, Air Canada, Iberia, Air Europa and KLM all flying into Lima.

From Europe, expect direct service from Madrid, Amsterdam and Paris, or one-stop via Bogota, Panama City or a US hub. From North America, Miami, Atlanta, Houston, New York, Los Angeles and Toronto all have direct or one-stop options. Typical fares from Europe run €650-€900 return in shoulder months (March-April, October-November) and €900-€1,400 in June-August peak. From Dublin expect one stop in Madrid or Amsterdam; from London direct on LATAM or BA codeshare.

Cusco (CUZ) is almost always reached by a 1h 20min domestic connection from Lima. LATAM, Sky and JetSmart run the route with 15+ daily flights in peak season. Fares are €80-€180 one way depending on season and booking window. Cusco altitude (3,400m) means your first day should be easy — plan for coca tea and a light schedule.

Iquitos (IQT) in the northern Amazon is Lima-only by air (no roads reach Iquitos — it is the largest city in the world unconnected by road). Flights are €90-€200 one way, 1h 45min.

For a 10-14 day combined Cusco + Amazon + Lima trip, book the international and domestic legs together through a single itinerary where possible. LATAM's through-fares from Europe to Cusco or Iquitos often beat booking separately.
