Machu Picchu in December: Complete Travel Guide
If you’re planning to visit Machu Picchu in December, you should know that it’s the rainy season, featuring greener landscapes and fewer crowds. December marks the start of summer in Machu Picchu (Southern Hemisphere) and coincides with the rainy season (November–April). During the day, temperatures are mild (around 66–79°F / 19–26°C) and cool at night (approx. 45–55°F / 7–13°C). However, the weather can change quickly: low clouds or morning mist are common, followed by sunny afternoons.
Weather and Temperature in Machu Picchu in December
- Warm daytime temperatures and cool nights. Daytime highs average around 79°F (26°C), while nighttime lows drop to about 55°F (13°C).
- Although days are longer, the weather is unpredictable: morning fog usually clears by midday, alternating between strong sun and cloudy periods.
- Humidity is high (around 60%) and it rains about 121 mm (4.7 inches) on average during the month.
- Dressing in layers is key: breathable t-shirts for the day and something warmer for the evening. Protect yourself from the sun and prepare for rain. Cold mornings may call for a light fleece, while afternoons are warm.
- Skies can change quickly: hot at noon and thunderstorms in the afternoon.
Rainy Season in Machu Picchu: How It Affects Your Visit
During the peak rainy season (December to March), Machu Picchu is often covered in morning mist, and heavy rains are common, especially from mid-December onward.
Common effects of rain include:
- Slippery and muddy trails, increasing the risk of falls.
- Higher risk of landslides, which may lead to temporary closures or transport delays (such as trains from Cusco).
- Reduced visibility in the morning mist: clouds often clear around noon.
Still, the rain enhances the lush landscape. With waterproof clothing and good footwear, you can enjoy the visit. A poncho or rain jacket and caution while walking are essential.
Inca Trail and Other Treks in December
The famous 4-day Classic Inca Trail is usually open in December, since its annual maintenance closure is only in February. However, due to the rains, the trek can become more challenging: muddy and steep sections make the hike demanding. Proper rain gear and cautious planning are crucial.
While the Inca Trail remains an option, many agencies recommend alternative routes during the rainy season for added safety. For example, the Inca Jungle Trek, Salkantay Trek, or Lares Trek are popular choices operated year-round. These also lead to Machu Picchu or nearby areas and offer different scenic perspectives without the Inca Trail crowds.
In general, the Inca Trail doesn’t close in December, but “it is recommended to be well equipped to avoid inconveniences” during the rainy season.
