Machu Picchu in December: Wet Season with a Holiday Spike

December is a low-crowd wet-season month with one loud exception: the Christmas and New Year holiday weeks. For most of the month the rain is building and the citadel is quiet, but around late December the holiday travel surge pulls a wave of visitors into the region, tightening lodging and dates in a way the rest of the wet season never does. It is the one stretch of the low season that behaves like peak.

That split personality is the whole story of December: plan it like a quiet green month if your dates avoid the holidays, and like a crowded one if they do not. This guide covers the December weather, the holiday-week crunch and how to plan around it, and the packing the deepening wet season calls for.

December weather: wet season deepening

December sits well into the wet season, so rain is a regular feature rather than an occasional visitor. Expect frequent showers and heavier afternoon downpours, muddy trails, and mist wrapping the peaks, with the mornings often clearer before the clouds build. It is atmospheric and green rather than the bright, dry clarity of the peak months.

The compensation is the landscape at its lushest and mild temperatures, warmer than the cold dry-season dawns even if the damp makes it feel cooler. An early start remains the wet-season move: catch the open morning sky over the ruins before the afternoon weather closes in.

As always in the mountains, plan for the range rather than a single forecast, and assume rain will find you at some point most days.

The Christmas and New Year spike

The defining feature of December is not the rain, it is the holidays. Around Christmas and New Year, the region sees a sharp travel spike as families and holiday travelers arrive, so the late-December weeks stand apart from the quiet wet season on either side. Cusco fills, lodging tightens, and the popular dates and slots get pressed in a way November and January never see.

The practical rule is to treat the holiday weeks like peak season and the rest of December like the low season it is. If your dates land near Christmas or New Year, book Cusco lodging and the scarce pieces with real lead time, because that window carries peak-season pressure inside an otherwise forgiving month. If your dates sit in early or mid-December, you get the quiet green wet season with short booking lead.

Crowds and booking, split by the calendar

Outside the holiday weeks, December is genuinely quiet, with low crowds and the short booking runway the wet season is known for. Inside them, demand jumps and the runway lengthens toward peak-season timelines. Which December you get depends entirely on where your dates fall.

Either way, entry stays rationed by the Peruvian authorities as timed, circuit-specific tickets, and the order of scarcity does not change:

  1. Inca Trail permits, the first to go, and tighter than usual over the holidays.
  2. The mountain add-on climbs, Huayna Picchu and Machu Picchu Mountain.
  3. The best entry slots on the most popular dates, especially the holiday weeks.

What to pack for December

December packing is a wet-weather kit first. You are planning for frequent rain, mud, and slick stone, so genuine waterproofing outranks heavy warmth here.

Our full checklist covers the details, but the December-specific priorities are these:

  • A serious rain shell and a pack cover or dry bags to keep gear dry through a downpour.
  • Waterproof, well-gripped footwear for muddy trails and slick stone.
  • Quick-drying layers rather than cotton, so a soaking does not leave you cold.
  • Sun protection for the clear morning windows, which still bring strong sun.

Questions travelers ask

Is December a good time to visit Machu Picchu?

It can be, with a caveat. Most of December is a quiet, green, wet-season month with low crowds and short booking lead, but the Christmas and New Year weeks bring a sharp travel spike that behaves like peak season. Plan by where your dates fall in the month.

Is Machu Picchu crowded over Christmas and New Year?

Yes, unusually so for the wet season. The holiday weeks pull a travel surge into the region, filling Cusco and tightening lodging and the popular dates. If your trip lands near Christmas or New Year, book the scarce pieces and Cusco lodging with peak-season lead time.

How much does it rain at Machu Picchu in December?

A fair amount; December is well into the wet season. Expect frequent showers and heavier afternoon downpours, with muddy trails and mist, though mornings are often clearer before the clouds build. Pack serious waterproofing and plan an early start.

How far ahead should I book for December?

It depends on the week. Early and mid-December often need only weeks, while the Christmas and New Year weeks need peak-season lead time, months, for the scarce pieces. The exact rules and release timing are set by the Peruvian authorities and can change; the current verified rules are in our Rules Center, dated when we last checked.
