Inca Trail In September

Things to know 

• Shoulder Season: September is considered a transitional or shoulder season. Temperatures are generally milder than in previous months, with a mix of sunny days and occasional, creating balanced trekking conditions.
• Orchids and Seasonal Flora: As spring begins in the Andes, hikers can observe blooming orchids and a variety of seasonal flowers along the trail, adding color and vitality to the landscape.
• Crowds: The Inca Trail continues to operate at full capacity, so encounters with many hikers are expected. However, at Machu Picchu, visitor numbers are slightly lower compared to the peak months of June, July, and August.
• Permits Sell Out Quickly: Despite being a shoulder month, permits for the Inca Trail can sell out rapidly for certain dates. This is partly due to school groups from Cusco and other regions of Peru organizing trips to Inca Trail in September, often in large numbers, which quickly reduces availability.
• Excellent Photography Conditions: September offers ideal conditions for photography. The combination of bright sunlight, occasional dramatic clouds, and lush mountain scenery provides excellent natural lighting.
• Light Rain and Atmospheric Views: Toward the end of the month, occasional light rain may occur. This often enhances the scenery, with low clouds moving through valleys and surrounding peaks, creating a striking and atmospheric environment.
• Unique Natural Sounds: A distinctive feature of late September is the sound of small toads along the trail. Their calls are especially noticeable after the second campsite, Pacaymayo, continuing toward Phuyupatamarca, adding a unique and memorable auditory experience to the journey.

Weather and Trail Conditions

• Rain: September marks the beginning of the rainy season along the Inca Trail. Light rainfall can occur, particularly during the second half of the month, as the first seasonal rains typically arrive at this time. However, rain is usually not constant throughout the day. Showers tend to last around two to three hours, after which the weather often clears. In many cases, precipitation is light and does not significantly affect the hike, making conditions generally mild and manageable.
• Temperature: During September, daytime temperatures along the trail typically range from 12°C to 25°C (54°F to 77°F), offering comfortable hiking conditions. Nights can be considerably colder, especially at higher-altitude campsites, although temperatures are not as extreme as in the preceding winter months. Nighttime temperatures usually drop to between 0°C and 7°C (32°F to 45°F). This is particularly noticeable at the second campsite, located above 3,600 meters, where the colder conditions are more pronounced.
• Visibility: Visibility in September remains generally good, as the majority of days are still sunny, allowing for clear views along the trail. After rainfall, low clouds often rise and drift across the mountains, creating ideal conditions for photography, including timelapse captures. These moving clouds enhance the landscape, giving it a dramatic and almost mystical atmosphere.

Pros Of Hiking Inca Trail In September

• Ideal Cloud Formations for Time-Lapse Photography: As September marks the beginning of the rainy season along the Inca Trail, light and occasional showers create dynamic cloud movements over the mountains. These shifting formations provide excellent conditions for capturing dramatic time-lapse videos and atmospheric landscape photography.
• Beautiful Rainbow Displays: The combination of intermittent rainfall and sunlight during September often produces striking rainbow displays. These natural phenomena add a unique and colorful dimension to the trekking experience.
• Excellent Opportunities for Wildlife Observation: With the arrival of spring in the Andes, vegetation begins to flourish, attracting a variety of fauna. This period is particularly rewarding for nature enthusiasts, as some species enter mating season, increasing the likelihood of wildlife sightings.
• Mild and Comfortable Temperatures: As part of the shoulder season, September offers milder temperatures compared to the colder winter months. Nights and early mornings are less intense, making camping and early departures more comfortable for hikers.
• Transitioning Mountain Landscapes: The first rains gradually transform the landscape, especially in the highlands. By the latter part of the month, hikers can observe a blend of green and grey tones as vegetation begins to regenerate, creating a distinctive and photogenic environment.
• Blooming Flowers and Native Orchids: Spring brings renewed life to the trail, with a variety of flowers beginning to bloom. Native orchids and other seasonal flora add vibrant colors and botanical interest along the route.
• Natural Shade from Cloud Cover: Increased cloud presence and occasional fog provide natural shade throughout the day. This helps reduce direct sun exposure and contributes to more pleasant hiking conditions.
• Increased Bird Activity: September offers a higher chance of spotting hummingbirds and other bird species, as they are drawn to the blooming flowers and nectar sources along the trail.

Cons Of Hiking Inca Trail In September

• Partial Cloud Cover During Seasonal Transition: Throughout September, particularly in the early weeks, clouds may begin to gather over the mountains as the region gradually transitions toward the rainy season. These clouds typically form in the early mornings and late afternoons, occasionally casting shadows over the landscape, although clear conditions still prevail for much of the day.
• Possibility of Light Rain Showers: Although September is generally considered part of the dry season, it also marks the beginning of a seasonal shift. As a result, occasional light rain showers may occur along the trail. These are usually brief and far less intense than during the peak rainy months; however, they can make sections of the trail slightly damp, so proper rain protection is recommended.
• Mist at the Sun Gate (Inti Punku): During or after rainfall, the area around Inti Punku may become misty. In some cases, visibility remains limited for a period of time, requiring hikers to wait for the clouds to clear before enjoying the full view of Machu Picchu.
• Increase in Mosquito Activity: With the arrival of the first rains, mosquito activity tends to increase compared to the previous months. Hikers may find them more noticeable, especially in warmer and more humid sections of the trail.
• Occasional Smoke in the Landscape: If early rains are delayed, it is common for local agricultural burning to take place in nearby jungle areas. This can result in visible smoke along parts of the trail, occasionally affecting scenic views.
• Limited Availability of Permits: September is considered a shoulder-season month but remains highly popular. Inca Trail permits often sell out well in advance. In many cases, they are quickly booked shortly after release, partly due to strong demand from local student groups from Cusco and other regions of Peru who organize hikes during this time. Therefore, last-minute availability is very limited

Recommendations

• Choose the Best Dates in September: It is advisable to plan your Inca Trail trek for early September rather than later in the month. During the last two weeks, there is still a possibility of occasional rain as the rainy season gradually approaches. In early September, weather conditions are generally more stable and drier, offering a more comfortable hiking experience.
• Prepare for Occasional Rain: Although September is part of the dry season, light rain can still occur, especially toward the end of the month. It is essential to bring a high-quality rain jacket or poncho. Rainfall is usually not heavy, but it can still leave you wet and uncomfortable if you are not properly prepared.
• Protect Your Electronic Devices: To keep your smartphone, camera, and other electronics safe, it is recommended to carry waterproof covers or sealed plastic bags. This simple precaution will protect your devices from moisture during unexpected showers.
• Book Inca Trail Permits Well in Advance: Permits for the Inca Trail are released during the first week of October and tend to sell out quickly. For this reason, it is strongly recommended to reserve your trek several months in advance to secure availability and avoid disappointment.
• Stay Informed Through Official Updates: We highly recommend following us on Instagram at https://www.instagram.com/abexpeditions/. We regularly share monthly videos of the Inca Trail, updates on permit releases, changes in regulations, and important information such as strikes or any situations that may affect travel on the Trail.
• Bring Warm Clothing for High Camps: Even though September is considered a shoulder season, temperatures at higher campsites can be quite cold, especially at night. Warm jackets and thermal layers are essential to remain comfortable during evenings and early mornings.

Do you have a rough idea of when the permits for September sell out by?

It all depends on Peru’s political situation. In 2019 before the pandemic the Inca trail permits run out 4 months in advance. However this year because of the strike that happened on January 2023 the Inca trail permits for September run out 3 weeks in advance for the first 2 weeks of September. And for the last 2 weeks, you could still find the Inca trail permits even upon arrival to Cusco.
