Machu Picchu in December

Rain, festivity and a holiday spike

December is a month of two characters. On the weather side it is firmly wet season — the southern Peruvian Andes run on two seasons rather than four, dry roughly May to September and wet roughly October to April, and December sits well inside the green, rainy half. On the human side it is the holiday season, with a demand spike around Christmas and a sharper one around New Year that runs against the otherwise modest off-peak crowds. The result is a month that rewards travellers who plan for rain and book the festive dates early.

There is genuine romance in a December trip. The cloud forest is at its lushest, mist wreathes the citadel, and the region's Christmas traditions — above all Cusco's Santurantikuy market — give the highlands a warmth that the clear, crowded dry season lacks. Machu Picchu sits at 2,430 m in a steep cloud-forest gorge, so cloud and rain are part of its nature; in December you lean into that, trading guaranteed blue skies for green hills, festive towns and the occasional clear afternoon breaking through.

December in a single card. Seasonal patterns are evergreen; verify exact ticket release dates, prices, event details and any closures with official sources before you lock plans.

• Weather: wet season — frequent rain and cloud, lush green, real chance of mist and occasional rail disruption.
• Crowds: modest most of the month, but Christmas and especially New Year see a sharp holiday spike.
• Events: Santurantikuy craft market fills Cusco's Plaza de Armas on 24 December; New Year brings its own festivities.
• Tickets: book the festive dates well ahead; off-peak slack disappears around 24 Dec–1 Jan.
• Pack: a proper waterproof shell, layers, waterproof footwear and sun protection for clear spells.
• Buffer: build a flexible day or two against rain delays and the holiday squeeze on trains and rooms.

Santurantikuy: Cusco's Christmas market

If you time a Machu Picchu trip around the holidays, Cusco's Santurantikuy is the reason to be in the city on 24 December. One of the largest traditional craft markets in the Andes, it fills the Plaza de Armas and surrounding streets with hundreds of artisans selling nativity figures, carved santos, ceramics, textiles and the moss and ornaments locals use to build their home nativity scenes. The name comes from Quechua and Spanish for the 'sale of saints', and the atmosphere — lantern light, woodsmoke, the bustle of families shopping for Christmas Eve — is a world away from the dry-season tour-bus circuit.

Pair the market with the city's Christmas Eve traditions and you have a memorable counterpoint to the citadel itself. Just remember that the same dates draw holiday travellers, so hotels in central Cusco fill up: book early if you want to be steps from the plaza for the market.

Weather: wet, green and changeable

December rain is more frequent and heavier than the gentle showers of November, though it tends to come in bursts rather than all-day deluge until you get deeper into January and February. Mornings often start cloudy or wet and clear into brighter afternoons, so the green-season playbook holds: favour an early entry slot when mornings are most often clearest, and keep your schedule loose enough to absorb a rained-out start. The reward is a citadel at its most atmospheric, wrapped in mist with the terraces glowing wet and green.

Altitude keeps the contrasts sharp. When the sun breaks through at 2,430 m the UV is intense and a hat and high-factor sunscreen earn their keep; cloud, rain or a pre-dawn start up in Cusco at 3,399 m turns cold fast. The dependable December kit is layers, a genuinely waterproof shell and footwear that copes with mud — the cloud-forest wet is the real thing, not a drizzle a token jacket will shrug off.

Holiday crowds, tickets and New Year pressure

December's crowd picture is uneven. For much of the month the green season keeps the overlook quiet and prices soft, but the holiday window — roughly Christmas through New Year — is a different beast, with domestic and international travellers converging on Cusco and the citadel. New Year in particular puts heavy pressure on hotels, trains and the prime ticket slots. The timed-entry system means you cannot turn up on the day in any case: since the post-2024 reorganisation by Peru's Ministry of Culture, every visit runs on a timed ticket tied to one of three circuits and a numbered route, with no general admission.

The practical takeaway: if your trip falls over the festive dates, treat it like high season and book early — entry ticket first, then train, then hotel, then any peak climb (Huayna Picchu or Machu Picchu Mountain). If you can travel in the first three weeks of December instead, you get the green season's calm and value without the holiday squeeze. Either way, leave a buffer day against both rain delays and the festive crush on transport.

Trekking, buffers and the altitude ladder

December trekking is wet but possible. The classic Inca Trail stays open — its only annual closure is February — and no-permit alternatives like Salkantay run too, through green, misty, quiet country. Expect mud, cold and wet on the high passes, and choose an operator comfortable with green-season conditions. Build flexibility in: the rains carry a small but genuine risk of weather disruptions, including the occasional landslide affecting the rail line, and that risk rises as the wettest months approach.

The altitude question is unchanged year-round and easy to forget amid the rain and the festivities. Cusco at 3,399 m sits nearly a kilometre above the citadel, so most soroche strikes on arrival in the city — which, conveniently, is also where Santurantikuy and the holiday life happen. Sleep low-to-high-to-low, ease into the lower Sacred Valley or pace your first Cusco days, and build a buffer day so a slow start never collides with a fixed, timed-entry ticket or a holiday train you cannot easily rebook.

So, is December a good time to go?

December suits travellers who want the green season's lush calm with a side of Andean Christmas — and who plan for rain. Outside the holiday window it offers quiet overlooks, soft prices and the mist-wreathed citadel at its most atmospheric, with Santurantikuy a unique reason to be in Cusco on Christmas Eve. The holiday dates themselves are a different proposition, with New Year pressure on tickets, trains and rooms that demands early, flexible booking.

Settle the dates, then run the plan in the usual order: lock the entry ticket first, then the train or trek, then any peak climb, with the altitude ladder and a weather buffer built in. Do that — and book the festive nights early — and December gives you a Machu Picchu trip with a warmth no dry-season month can match.
