Weather can greatly change your experience on the Inca Trail. The same section of the trail can be a dry path with clear views of snow-capped mountains or a damp stone stairway covered in mist, depending on the month you travel. Understanding the weather in each season helps you choose your travel dates, pack the right gear, and know what to expect each day.
How Weather Changes Along the Trail
There isn’t just one type of weather on the Inca Trail. During the trek, you’ll pass through very different ecological zones, and temperatures vary depending on the altitude and time of day.
Differences Between Higher and Lower Sections
At Warmiwañusqa Pass, approximately 4,215 meters above sea level, the air is cold and dry, and the wind can be strong. In contrast, as you descend toward Wiñay Wayna and Machu Picchu, at approximately 2,430 meters above sea level, you enter the cloud forest, where humidity is higher and temperatures are milder.
Daytime and Nighttime Temperature Differences
During the day, the sun can be intense, especially around midday. At night, temperatures drop quickly at the higher campsites, and during the dry months, they can reach around or below 0°C.

Dry Months: Clear Skies and Cold Nights
May
It’s one of the most balanced months. The rains have almost disappeared, but the landscape still retains the greenery of the previous season. Days are sunny, and nights begin to get cold.
June
You’ll enjoy very clear skies and good visibility along the higher sections of the trail. It’s also one of the coldest months at night. Cusco celebrates Inti Raymi on June 24, which increases demand for hotels and permits around those dates.
July
This month coincides with vacations in several countries and Peru’s Independence Day celebrations, making it the busiest month for hikers. The weather is dry and stable, but nights at Pacaymayo are the coldest of the year. A good sleeping bag is essential.
August
Conditions remain dry, with sunny days and gusts of wind at higher elevations. On some days, haze may appear due to grassland burning in nearby valleys. Nights remain cold.
September
Nights become slightly milder, and the number of visitors begins to decrease toward the end of the month. It’s a good option if you’re looking for dry weather with somewhat fewer people.
Transition Months: April and October
April
Rainfall gradually decreases, and the cloud forest is at its greenest. Orchids are commonly seen along the lower sections. It may rain on some afternoons, so it’s best to keep a rain poncho handy.
October
The first rains begin, usually brief showers in the afternoon. Mornings are generally clear, and nights are less cold than in July. Demand remains high, but it’s lower than during the middle months of the year.
Rainy Months: Greener Landscapes and Fewer Hikers
November
Rain becomes more frequent, although there are still clear days. Nighttime temperatures are milder, and the trail is less crowded.
December
It rains regularly, and mist often covers the higher sections. Demand increases during the Christmas and New Year’s holiday weeks, so it’s important to book those dates in advance as well.
January
It’s one of the rainiest months. The stone steps become slippery, and some sections of the trail may be muddy. On the other hand, you’ll encounter fewer hikers and very green landscapes.
February
The Inca Trail closes for the entire month for maintenance. Machu Picchu remains open, so you can visit by train or choose alternative routes such as the Salkantay Trek.
March
The trail reopens while rainfall is still frequent, gradually decreasing toward the end of the month. It’s a good time to hike if you prefer fewer groups around you and don’t mind the humidity.
Which Month to Choose Based on Your Travel Preferences
- If clear views are your priority: May through September, with June and July offering the clearest skies.
- If you prefer fewer people: March, November, or the second half of September.
- If you’re sensitive to cold: April, October, or November, when nights are milder.
- If you’re interested in plant life: April and May, when the cloud forest is at its greenest.
Keep in mind that the months with the best weather are also the busiest. If you’ve already chosen your travel dates, check our guide to Inca Trail permits and how far in advance to book so you don’t miss out on a spot.
Clothing and Gear by Season
For the Dry Months
Prioritize warm clothing for nighttime: a down or synthetic insulated jacket, a warm hat, gloves, and a sleeping bag rated for below-freezing temperatures. During the day, you’ll need sunscreen, a sun hat, and sunglasses.
For the Rainy Months
Bring a waterproof jacket, rain poncho, backpack rain cover, and bags to keep your clothes dry. Boots with good traction and trekking poles provide stability on wet stone steps.
Regardless of the month, plan to spend one or two days in Cusco before and after your trek. If you arrive during the rainy season, a cacao ceremony in Cusco is a relaxing way to spend a rainy afternoon while your body adjusts to the altitude.
