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

Peru is not one climate. It is three, and they keep three incompatible calendars. Getting this straight before you book anything saves you a great deal of re-planning later.

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 dip below freezing above 3,500m, and trail conditions you can plan around. Wet season is December through March: afternoon rain most days, mud underfoot, landslide risk on rural roads, and the Inca Trail shut every February. April, October and November are the shoulder months — cheaper, quieter, and a little more of a weather gamble.

The Amazon basin — Puerto Maldonado, Tambopata, Manu, Iquitos — flips the whole thing on its head. Wet season runs November to April with daily rain, high water and boat access to flooded forest. Dry season is May to October with lower rivers, exposed trails and stronger wildlife viewing on foot. Neither season wins outright; they are simply two different trips, which we get into in section four.

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

Because the prime Machu Picchu window sits in May-September, most Peru trips simply accept Lima's grey garua as the price of admission.

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 strictly rationed. Peru's Ministry of Culture releases 500 permits a day, of which roughly 200 go to trekkers and the rest to the guides, porters and cooks who make the whole thing possible. Each permit is tied to your passport number, can't be transferred, and can't be resold, so there is no scrambling for someone else's at the last minute.

For the peak dry months of May through September, permits vanish 5 to 7 months ahead, and June and July dates are often gone by January of the same year. If your dates are fixed and land in peak season, book the moment the next year's permits release, which is usually October of the year before.

The shoulder months are kinder. April, October and November permits tend to be there 2 to 3 months out, and December and January often have space close to the date, though you will be walking on wet, muddy ground.

Then there's February, when the Inca Trail closes completely. Every year, no exceptions. Crews carry out the heavy maintenance and the rains turn several stretches genuinely dangerous. Machu Picchu itself stays open the whole time, reached by train from Cusco or Ollantaytambo.

The great consolation prize is the Salkantay trek: 4 to 5 days, higher and wilder, no permit cap, and running year-round including February. Plenty of travellers who miss out on Inca Trail permits come home preferring Salkantay anyway, won over by the scenery — the 21,000ft Salkantay peak, the impossibly turquoise Humantay Lake — and the thinner crowds. Lares, Choquequirao and the Inca Jungle route are the other permit-free ways in.

If it has to be the Inca Trail and nothing else, lock your dates 6+ months out and make peace with the fact that there is no same-year flexibility for June to August.

The Amazon trips people up because the obvious logic — dry good, wet bad — simply doesn't hold here. Both seasons are wonderful. They are just two entirely different jungles.

Dry season (May to October) drops the rivers 5-8 metres in Tambopata and Manu, and trails that spend half the year underwater open up to your boots. The clay licks where macaws and parrots gather are at their loudest, jaguars and giant otters turn up on the exposed sandbars, and the mosquitoes ease off. Mornings are sunny, afternoons bring the odd shower, and the whole thing dovetails neatly with a dry-season Cusco trip. This is where most first-timers start, and rightly so.

Wet season (November to April) is the one that surprises people. The water rises and floods huge swathes of forest, and suddenly you're gliding by canoe between the trunks of standing trees, into pockets no walker could ever reach. Fishing comes into its own — piranha, peacock bass — pink dolphins surface in the flooded channels, and the fruiting trees pull in monkeys, sloths and birds. The rain is honest about itself: usually an hour or two late in the afternoon rather than an all-day grey.

Iquitos and the northern Amazon, around the Pacaya-Samiria reserve, run this rhythm even harder because the river network is so much bigger. A January-March flooded-forest trip from Iquitos is a genuinely different animal to a May-September Tambopata hike.

Want the Amazon and Cusco in one go? May, June and September line up cleanly, dry in both. Set your heart on the flooded forest instead, and you'll want a coast-and-jungle trip that skips the Andes, or you accept some mud on the Cusco trails.

Almost everyone arrives in Peru through Lima (LIM), Jorge Chavez International, which got a shiny new terminal in 2025 and now takes the wide-body long-haul schedules with ease. LATAM all but owns the place — it is the de facto national carrier — and you'll also find Avianca, Copa, American, Delta, United, Air Canada, Iberia, Air Europa and KLM dropping into Lima.

From Europe, expect direct flights out of Madrid, Amsterdam and Paris, or a single stop via Bogota, Panama City or a US hub. Peru is closest and cheapest from North America — Miami, Atlanta, Houston, New York, Los Angeles and Toronto all connect direct or one-stop, and fares run lower than from anywhere else. As a rough guide, North American return fares sit around US$550-850 in the March-April and October-November shoulder, climbing to US$900-1,400 across the June-August peak; European fares run €650-€900 in shoulder and €900-€1,400 at peak; Australian travellers route via Santiago or a US hub (roughly A$2,000-3,000 return) and have the longest haul of the three. From Dublin you'll usually stop once in Madrid or Amsterdam; from London you can go direct on LATAM or the BA codeshare. Multiday.tours prices the flight live from your own airport in your own currency.

Cusco (CUZ) is nearly always a quick 1h 20min hop up from Lima. LATAM, Sky and JetSmart fly it hard — 15-plus departures a day in peak season — and one-way fares run roughly €80-€180 depending on the season and how far ahead you book. At 3,400m, Cusco asks you to take your first day gently: coca tea, an unhurried schedule, and let your lungs catch up.

Iquitos (IQT) out in the northern Amazon can only be reached by air from Lima, because no road reaches it at all — it is the largest city on the planet you cannot drive to. Flights are roughly €90-€200 one way, 1h 45min in the air.

For a 10-14 day Cusco-Amazon-Lima loop, try to book the international and domestic legs as one itinerary where you can. LATAM's through-fares from Europe to Cusco or Iquitos often come in cheaper than stitching the legs together yourself.
