When you picture the Salkantay Trek, your mind probably goes to stunning images of snow-capped peaks, turquoise lakes, and the magical citadel of Machu Picchu. And while all of that is true, there’s another main character in this adventure that doesn’t always get the spotlight it deserves: Mother Nature in her most unpredictable and fascinating form. The weather along the Salkantay Trek isn’t just a variable; it’s an experience in itself. You’ll go from feeling the biting cold of the high mountains to being drenched in the warmth and humidity of the tropical jungle, all in a matter of days. It’s a transformation as radical as the journey itself.
This ever-changing nature is precisely what makes preparation so crucial. While Instagram photos often show clear blue skies, the reality is that Salkantay has a very particular personality. There’s a local saying in the Andes that you can experience all four seasons in a single day. And believe me, on the Salkantay, that phrase isn’t an exaggeration—it’s a promise.
The weather, with all its capricious beauty, is the guiding thread of this guide. It’s not a cold list of facts, but a roadmap to understanding, respecting, and, ultimately, preparing for the true spirit of the Salkantay. We want your backpack to be filled not just with the right clothes, but also with the right mindset to embrace any surprise the Andean sky decides to throw your way.
The Salkantay Trek is a journey through an astonishing variety of ecosystems, and each one has its own climate. Imagine the trail is a book, and each day is a chapter with a completely different landscape and climate.
The first act takes you to high altitudes, to landscapes worthy of an epic film. Here, temperatures can be severe, with the Andean cold chilling you to the bone, especially when the sun hides. This is the part of the hike where the winds remind you that you are at the top of the world and where every layer of clothing feels like a life-saving hug.
But as the trail descends, the script changes completely. The cold air of the high plateau fades, replaced by the warmth and lushness of the cloud forest. The air becomes denser, more humid, and the sounds of nature intensify. The trees are greener, the insects are noisier, and the mist clings to the slopes, creating a mystical atmosphere. It’s a whole new world, and the change in weather is the clearest sign that you’ve left one kingdom to enter another.
This dramatic transition is what makes the Salkantay so special, but also so challenging in terms of preparation. One day, you’ll be bundled up in a hat and gloves, and the next, you’ll be rolling up your shirt sleeves and putting on insect repellent. The key, as in life, is adaptability.
Below, we’ll break down the weather for each day of the Salkantay Trek, with estimated temperatures. These numbers are just a reference, because, as I’ve said, the Andes can be full of surprises. The real key is to understand what each day will demand of you.
The journey begins with the familiar warmth of Cusco, but don’t be fooled. As the bus takes you towards Mollepata and Soraypampa, the temperature starts to drop noticeably.
In Soraypampa, you’ll be at almost 4,000 meters above sea level. This means the night can get very, very cold. While the daytime temperature might reach around 14°C (57°F), the estimated minimum can drop to 2°C (35°F), or even lower. The wind chill can make it feel even colder, especially if there’s a breeze.
Personal tip: Do not underestimate the cold of the first night. It’s crucial to bring quality warm clothing for the campsite: a down jacket, a warm hat, gloves, and a sleeping bag rated for sub-zero temperatures. People are often surprised by how much the temperature drops once the sun sets behind the mountains.
What to expect? During the hike, the weather will be cool. You might start with a jacket and end up in just a long-sleeved shirt. The sky can be clear, but clouds might roll in during the afternoon, bringing the possibility of a short rain shower. A rain poncho is your best friend—keep it handy.
This is the day everyone remembers. The journey begins in the cold of Soraypampa and ascends to the highest point of the entire trek: the Salkantay Pass at 4,600 meters (15,091 ft). Here, the air is thin and the temperatures are the lowest of the whole trail.
At the summit of the pass, the weather is unpredictable. The temperature can fluctuate, but it will always be cold. It’s common to see snow or even sleet, and the wind can be relentless. The feeling of accomplishment upon reaching the summit is immense, but so is the need to bundle up well.
Personal tip: Before the hike, make sure you have several layers of clothing on. A good pair of gloves, a warm hat that covers your ears, and a scarf or neck gaiter are essential. A down jacket or a similar one is a must. And don’t forget a good backpack to store your layers as you descend.
The transformation: Once you start the descent from the pass, the magic happens. The climate changes dramatically. In just a few hours, the vegetation begins to get more lush and the air feels warmer and denser. By the time you reach Chaullay, you will have gone from polar cold to a more temperate, almost tropical environment. It’s a change you’ll notice not only on the thermometer but in every pore of your skin.
The third day is a total immersion into the jungle. The high altitudes and the cold are now behind you. The hike is a constant descent through a landscape that transforms completely. The air becomes warm and humid, and the vegetation surrounds you everywhere, lush and alive. Here, the sound of waterfalls and birds fills the air, creating an atmosphere of peace and tranquility. It’s a welcome change after the physical demands of the previous day.
Personal tip: Although temperatures are pleasant (the maximum can reach 22°C / 71°F and the minimum 15°C / 59°F), the humidity is high. This means that clothes dry more slowly. Opt for lightweight, breathable fabrics that dry quickly. And please, don’t forget a good insect repellent. Mosquitoes and other bugs are permanent inhabitants of this ecosystem, and you don’t want to end up with bites all over your body.
What to expect? Intermittent rain is common in the cloud forest. It often comes as a soft drizzle that refreshes the air, but it can become more intense at any moment. A rain poncho will allow you to keep hiking without problems, keeping your backpack and clothes dry.
The penultimate day is a combination of ascents and descents that bring you closer to your final destination. The hike takes you through coffee plantations and up to the Llactapata archaeological site, from where you’ll get a breathtaking view of Machu Picchu. This stretch maintains the warm and humid jungle climate, with temperatures similar to Day 3 (maximums of 24°C / 75°F, minimums of 18°C / 64°F).
Personal tip: The sun can be strong and the humidity intense, so protection is key. Wear sunscreen on all exposed areas, a hat to protect your face, and sunglasses. And stay hydrated by drinking water constantly, as the combination of heat and physical effort can be exhausting.
The great reward: The hike for this day ends with an exciting stretch along the train tracks, finally arriving at the bustling town of Aguas Calientes. Here, the adventure feels more urban, and you can relax and prepare for the big day. The weather remains warm and humid, perfect for a relaxing dinner and a well-deserved rest.
The culminating moment arrives. The final hike to the citadel of Machu Picchu. The weather here is, again, a reflection of the cloud forest: warm and humid, with the possibility of rain at any time (maximums of 24°C / 75°F, minimums of 16°C / 60°F).
Personal tip: Even if the day seems clear, bring a raincoat or a poncho with you. Clouds can roll up and down the mountain quickly, and an unexpected rain shower is part of the experience. The morning light is spectacular, but if you go during the rainy season, mist can cover the ruins, creating a mystical and photographic atmosphere. Don’t be discouraged; it’s part of the place’s magic.
Enjoying the moment: Dress in lightweight layers so you can take them off as the temperature rises, but have something on hand in case of rain or cloud cover. Your main focus should be soaking in the energy of the place. You’ve made it, and the weather, whatever it may be, is part of the story.
To truly understand the climate of the Salkantay, it’s helpful to have an idea of the climate in Cusco, the gateway to your adventure.
Cusco has two main seasons: the dry season (from April to October) and the rainy season (from November to March).
Dry Season (April to October): This is the most popular period for the trek. Days are usually sunny, and temperatures are pleasant. However, the nights, especially in the high mountains, are very cold. The sun shines intensely, so sun protection is crucial.
Rainy Season (November to March): Although there’s a higher chance of rain, this period has its own charm. The landscape becomes a deep green, and there are fewer people on the trails. Daytime temperatures are a bit warmer than in the dry season, but the nights are not as extreme.
Transitional temperatures:
September, October, November, and December often have a nice average temperature. September, in particular, can be the warmest month on average, while January can be the coolest. However, remember that these are just averages.
Understanding the Salkantay’s climate isn’t just about numbers; it’s about preparing for the feeling.
The Andean sun: At high altitude, UV rays are much stronger. Even on a cold day, you can get sunburned if you don’t wear sunscreen.
The rain: In the jungle, rain is almost a constant. Sometimes, it’s a fine drizzle; other times, a brief but intense storm. A poncho or a waterproof jacket will give you the freedom to enjoy the landscape without worries.
Your clothes: a second skin: The key is the layering system. A base layer that wicks away sweat, a mid-layer that insulates, and an outer layer that protects from wind and rain. This way, you can adapt to every change in weather without having to unpack everything from your backpack.
In short, the Salkantay’s weather is an adventure in itself. It’s the backdrop that makes the experience so memorable. Preparation is key, but the true magic lies in embracing every change—every raindrop and every ray of sun. Because in the end, it’s not just about reaching Machu Picchu, but about enjoying every single step of the way.
The months September, October, November and December have a nice average temperature.
