Machu Picchu Climate

Tucked away in Peru’s cloud-forest is an incredible feat of ancient architecture. Machu Picchu is located in the Andes Mountain range, high above the Sacred Valley . Sunny winters and rainy summers make up the general climate of these subtropical highlands.

Two other important factors are the site’s proximity to the equator, as well as its elevation of over 7,972 feet or 2,430 meters. The average highs throughout the year remain fairly consistent. However, potentially frosty nights are not uncommon as temperatures begin to decline in May. 

With over 100 rainy days per year, the site tops out around 71 inches or 1803.4 mm of precipitation per year. The majority can be expected beginning in the shoulder months of October and November, all the way to March. Occasional thunderstorms pass over the mountainside and, although very rare, hail is not unheard of.

On the bright side, 2,460 hours of annual sunshine also greet you while visiting Machu Picchu. Dewey mornings tend to be thick with mist. As afternoon approaches the sun finds its way through, illuminating the ruins. This becomes even likelier during the transitional month of April as the dry season approaches.

But, be prepared with lots of sunscreen and a protective hat! The ultraviolet rays are much more powerful at this altitude. Lastly, although extreme temperatures are uncommon and the terrain isn’t too challenging, it’s important to dress in layers while sporting a reliable pair of walking shoes.

Machu Picchu Rainy Season

Machu Picchu’s rainy season occurs in the southern hemisphere’s summer, between the months of December and March. The higher chance of precipitation, beginning in January, coincides with the slower tourism season. Cloudy days can be deceiving, as the sun’s rays are still strong on your journey from Cusco to Machu Picchu.


December marks the beginning of summer here in Machu Picchu, Peru . Although it has the warmest temperatures, it is also peak time for heavy rainfall. Thunderstorms are possible during the day, as the sky is prone to change at a moment’s notice. You may ask yourself, is Machu Picchu safe to visit with all this rain? Don’t worry, the answer is yes! Trails can become more slippery, but the Peruvian government takes extreme precautions to keep all of its visitors safe. The worst you should expect is to get a little wet during your tour of the ruins. 

December Monthly Averages: Night Time vs. Daytime Temperatures: Between 55.4°F and 78.8°F (13°C and 26°C) Rainfall: 4.8 inches (121mm) Humidity: 60% Daily sunshine: 6 hours UV Index: 12


January is marked by overcast skies in the early hours of the morning, eventually leading to warmer temperatures later in the day. This can help while snapping your perfect picture of the ruins . January’s milder climate is intermixed with heavy rainfall and misty horizons. Taking advantage of daylight is crucial as it can sporadically be overtaken by clouds in the afternoon. 

January monthly averages: Night Time vs. Daytime Temperatures: 55°F and 77°F (12.8°C and 23.9°C) Rainfall: 5.4 inches (138mm) Humidity: 62% Daily sunshine: 5 hours UV Index: 12

Persistent rain continues in Machu Picchu as February averages about 20 days of precipitation. It may not be the best time to hike Machu Picchu, as wet trails and cloud coverage is to be expected. But, it is important to remember that when they do dissipate the sun will be strong. Wearing the proper clothing is important to protect yourself from its intensity. The cloud-forest will have you enjoying warm afternoons and humid nights. 

February Monthly Averages: Night Time vs. Daytime Temperatures: 55°F and 77°F (12.8°C and 24.9°C) Rainfall: 5.6 inches (141 mm) Humidity: 65% Daily sunshine: 5 hours UV Index: 12

*Important Reminder* – Although Machu Picchu remains open, the Inca Trail is closed for the month of February. This is partly due to yearly routine maintenance, but also because the persistent rain can make the trail unsafe for travelers. It may not be the most popular time for your hike to Machu Picchu, but you’re in luck! As long as conditions remain safe, there are a few Inca Trail alternatives that you can try as well.


On average, March is the rainiest month out of the year in terms of overall precipitation. Temperatures begin their slow decline during this period, while the humidity maintains a higher heat index. Anticipate cloudy skies coming and going during the day. However, once the sky clears, there is ample sunshine to light up the Machu Picchu ruins .  As with every month in the rainy season, March is beneficial if you’re looking to avoid the massive crowds later in the year. So you may get a little wet, but you’ll have much more free space while roaming the site.

March Monthly Averages: Night Time vs. Daytime Temperatures: 55°F and 77°F (13°C and 25°C) Rainfall: 5.9 inches (151mm) Humidity: 62% Daily sunshine: 6 hours UV Index: 12

Transition to Dry Season

As rainfall begins to let up, and Machu Picchu weather transitions, the saturated mountainside welcomes lush vegetation and sunnier afternoons. 


Being that April is a transitional period, there will be a noticeable decrease in the amount of rainfall at the Inca citadel. On average about 9 days out of the month will see rain sprinkled throughout the afternoon and into the night. As the cloud coverage reduces you may want to take a shot at climbing Machu Picchu mountain . Although, you will note an increase in other travelers making the same trek.

April Monthly Averages: Night Time vs. Daytime Temperatures: 54°F and 77°F (12°C and 25°C) Rainfall: 2.4 inches (62 mm) Humidity: 61% Daily sunshine: 7 hours UV Index: 12

Machu Picchu Dry Season

The dry season in Machu Picchu is also peak tourism season. Visitors flock to the blooming mountain as the chance of rainfall remains minimal over the next few months.


May, the entryway into the dry season here in the Peruvian Andes. Days become warmer and brighter, while sundown brings with it cooler mountain temperatures.

It is still advisable to wear layers of clothing as well as protective headwear for the temperature fluctuations. 

July Monthly Averages: Night Time vs. Daytime Temperatures: 48°F and 77°F (9°C and 25°C) 48°F and 77°F (9°C and 25°C) Rainfall: 0.9 inches (22mm) Humidity: 45% Daily sunshine: 8 hours UV Index: 10

The call of the coming rainy season becomes most prominent in October as the average rainfall almost doubles from September. Skies remain spotted with clouds as the daily humidity rises. However, enough sun makes its way through to warm up the afternoons. Not only is this a shoulder month in terms of weather, but also in terms of the declining rate of tourists.
