The Salkantay Trek is a breathtaking journey through some of Peru’s most diverse landscapes, from snow-capped mountains to lush jungles. However, the weather along the trek can be unpredictable and varies significantly depending on the altitude and time of year. In this guide, we’ll break down the Salkantay Trek weather patterns, what to expect during each season, and how to pack and prepare for the conditions you’ll encounter.

The Salkantay Trek’s weather is unpredictable, extreme, and breathtakingly diverse. If you’re planning this adventure, understanding the climate is the difference between misery and magic. Here’s everything I learned from trekking through rain, snow, and scorching sun—plus tips to outsmart the elements.

Why Salkantay’s Weather is Wild (And How to Prep)
This trek smashes you through four microclimates in 5 days:
- High Andes (Day 1–2): Freezing nights, potential snow, and brutal UV rays.
- Cloud Forest (Day 3): Misty, damp, and moody—like hiking through a fairytale.
- Jungle (Day 4–5): Sweltering heat, sudden downpours, and mosquitos.
Key Challenges:
- Altitude sickness (thin air at 4,600m + rapid weather shifts = nasty headaches).
- Temperature swings (from -5°C at dawn to 25°C by noon).
- Rainy season surprises (trails turn to sludge, but crowds vanish).

Weather Hacks I Wish I Knew Sooner
- Start Early: Afternoon storms are routine—hit the trail by 5 AM to dodge downpours.
- Cover Up at Altitude: Sunburn + altitude = misery. I used a buff + SPF 50 religiously.
- Sleep with Your Electronics: Cold drains batteries. Keep your phone in your sleeping bag.
- Embrace the Poncho: Even with a fancy rain jacket, a $2 plastic poncho saved my pack.
- Check the Moon Phase: Full-moon treks mean icy nights but epic stargazing.
Worst Weather Disasters (And How to Avoid Them)
- Hypothermia Close Call: A hiker in my group wore cotton sweatshirts—they spent Day 2 shivering in a emergency blanket. Fix: Pack synthetic or wool only.
- Whiteout at the Pass: Zero visibility happens. Fix: Guides know alternate routes—stick close.
- Jungle Flash Floods: A 2023 group got stranded overnight. Fix: Check Senamhi (Peru’s weather org) before Day 4.
