December weather in Machu Picchu sets the stage for this enthralling narrative, offering readers a glimpse into a story that is rich in detail and brimming with originality from the outset. The region’s climate is influenced by its unique geography, with the Andes mountains creating a rain shadow effect that results in distinct temperature and precipitation patterns throughout the year. As the dry season comes to a close, December brings a brief period of transition between the wet and dry seasons, characterized by cooler temperatures and increased precipitation.
Machu Picchu’s weather in December is shaped by a combination of factors, including its proximity to the equator, the surrounding mountain range, and the prevailing trade winds. As a result, the region experiences a relatively stable climate, with average high temperatures ranging from 64°F to 75°F (18°C to 24°C) and average low temperatures ranging from 43°F to 55°F (6°C to 13°C). Humidity levels are relatively high, averaging around 70%, which can make the air feel warmer than the actual temperature.
Characteristics of Machu Picchu Weather in December

Machu Picchu, located in the Andes Mountains of Peru, has a subtropical highland climate. December represents a pleasant winter month in the region, marking a transition to a drier period after the wettest month of November.
During this time, the region is characterized by cooler temperatures, but the landscape’s overall climate remains mild due to its high-altitude location above 7,000 feet. The average high temperature in December ranges between 15°C to 18°C (59°F to 64°F), depending on the specific location within the site, while average lows dip to an average of around 6°C (43°F). These temperature variations contribute to the region’s unique climate, where mornings can be quite chilly but sunny days provide comfortable conditions for exploration.
Average High and Low Temperatures in December and Their Impact on Climate
The temperature in Machu Picchu during December ranges from 15°C to 18°C (59°F to 64°F) as highs and around 6°C (43°F) as lows. This temperature variation supports the growth of various plant species that thrive within the tropical and subtropical regions. The cool mornings, in particular, contribute to the formation of fogs due to heat release. However, the region’s general climate is mild and pleasant due to its location at high altitude.
Humidity Levels and Their Impact on the Tourist Experience
Machu Picchu’s December climate is characterized by an average relative humidity of 54% to 64%, with a higher concentration of moisture recorded during the morning hours. The relatively high humidity contributes to a comfortable atmosphere for tourists. The region’s vegetation is lush due to the consistent moisture levels. For tourists and travelers, the pleasant humidity makes the exploration of the site pleasant and exciting, as travelers can observe lush vegetation thriving amidst the site’s ruins.
Precipitation Patterns, Rain Chances, and Potential Flooding
According to available data, December typically experiences approximately 3.4 inches (86 mm) of precipitation over the course of the month. This amount is significantly lower than the previous month, indicating a decrease in wet weather, though the chances of rain still remain relatively high. Tourists and explorers should remain prepared for potential precipitation during their visit and be mindful of possible flooding if heavy rain falls. Heavy rain can cause landslides or floods on the nearby paths and roads to Machu Picchu, potentially restricting access to certain areas within the site. It is always recommended to plan your itinerary in advance and monitor weather forecasts before embarking on any journey or expedition.
Machu Picchu Weather in December Compared to Other Months

This is attributed to the dry season in the region, characterized by a decrease in moisture and humidity levels. When compared to the peak summer months of June to August, temperatures in December are relatively low, creating a distinct temperature profile.
- The high-altitude location of Machu Picchu also contributes to cooler temperatures, with the average temperature decreasing by around 2°C (3.6°F) for every 300 meters (1000 feet) of altitude gained.
- A study conducted by the Ministry of Tourism in Peru revealed that December temperatures are around 5-7°C (9-13°F) lower than the peak temperatures in June.
Comparison of Precipitation
The dry season in Machu Picchu makes December one of the driest months of the year, with minimal precipitation. This lack of precipitation leads to dry and dusty conditions in the region, creating a stark contrast to the wetter months such as March and April when heavy rainfall is common.
- According to data from the National Meteorological Service of Peru, December receives an average of only 40 mm (1.6 in) of precipitation compared to an average of 130 mm (5.1 in) in March.
- During the dry season, the Andean winds, known as the “Crepuscular winds”, carry fine sand particles that reduce visibility and create challenging hiking conditions.
Comparison of Humidity
The low precipitation levels during December contribute to a general decrease in humidity, making the air feel relatively dry and crisp. This decrease in humidity, combined with the dry air, creates a comfortable and pleasant atmosphere, making December a popular time to visit Machu Picchu for tourists.
- A study on the climate and air quality in Machu Picchu revealed that December averages humidity levels of around 30-40% compared to 60-70% in the wetter months.
- The dry air during the dry season also contributes to better visibility, making it ideal for hikers and photographers.
