How to Dress for Peru’s Diverse Climates

Dress in layers rather than relying on single heavy garments. Because you will encounter everything from humid coastal heat to freezing Andean peaks and jungle moisture, a technical layering system is your only way to stay comfortable.

  1. Pack for the 'Three World' zones. Divide your suitcase into three categories: coastal/Lima (mild/humid), Andes/Cusco (intense sun/cold nights), and Amazon (hot/wet). You need versatile items that cross these zones.
  2. Master the base layer. Use moisture-wicking synthetic or merino wool shirts as your base. Avoid cotton for trekking or high-altitude areas, as it holds sweat and makes you cold once the sun drops.
  3. Invest in a packable down jacket. Even in the dry season, temperatures in the Andes can drop below freezing at night. A lightweight, packable down or synthetic puffer jacket is essential for layer-on-layer warmth.
  4. Choose the right footwear. Bring one pair of waterproof, broken-in hiking boots for the Andes and one pair of comfortable walking shoes for city sightseeing. Do not bring brand new shoes, or you will deal with blisters on cobblestones.
  5. Prepare for extreme UV. The sun is significantly stronger in the Andes due to altitude. Pack a wide-brimmed hat, polarized sunglasses, and high-SPF sunscreen, regardless of the temperature.
Do I really need heavy winter clothes for Machu Picchu?
It depends on the time of day. It can be 70°F (21°C) at noon and 35°F (2°C) at 5:00 AM. Layers are the only way to survive this fluctuation.
Can I just buy clothes there if I run out?
Yes. Cusco has fantastic markets for alpaca wool garments. You can buy warm, locally-made layers easily if you find yourself underprepared.
