Located on an altitude of about 1000 meters lower than Cusco and relatively close the Amazon Rainforest just over 100 kilometers away, the weather in Machu Picchu as you can imagine is quite unpredictable. Partially influenced by the grills of the Andean Highlands Climate, quickly changing weather, clouds interchanged with sunny moments and strong winds, together with the influences coming from the Amazon Basin, humidity and rain, it is obvious that Machu Picchu can have several seasons in one day. The Machu Picchu weather is dominated by the cloud formation caused by the shock between the highland colder winds and the humidity coming from the tropical jungle area. In general the weather in Machu Picchu knows two seasons; the wet and the dry season. The summer time is when there is more rain in the area. These are the months December through March. In February the INC, the National Cultural Institute, closes down the Inca Trail as well for being too dangerous and to use the time to do maintenance and cleaning operations. The dry season would be from April to November, but especially in the beginning and end you can never exclude some rain in the evening and even during the day. At times, especially in the rainy season this makes for some days when Machu Picchu can hardly be seen from the surrounding Mountaintops.
In the dry season, even though some clouds can be formed, days will mostly be clear and open (especially in the afternoon) giving way for the great views of Machu Picchu as seen on many pictures. Nevertheless the above is an indication; it may as well be that you will encounter other weather patterns than the season you may be traveling in. Being subject to so many influences, it will never be really cold at Machu Picchu but sun, rain and wind can never be discarded completely. Normally the weather in Machu Picchu is clearest in the months June, July and August. Nevertheless no matter the weather you may have, it will always contribute to the magic and beauty of this amazing site.
