Climate of the Andes of Peru

In the Andes, he climate varies with the elevations, but in general, the weather in the high Andes, also called Altiplano or Puna is cold. As elevations vary, it is not possible to give temperature data for the entire region. In general, temperatures decrease 0.6 °C per 100 m, while precipitation will increase. In general, rainfall on the Altiplano also increases from the coast to the Amazon.

 

The winter is  from May to September with low precipitation and often sunny skies. The rainy season, with overcast skies, are from December through March. During the summer, average temperatures may not rise all that much, but on a sunny day, it may still feel rather warm, depending also on the elevation. UV is brutal in the high Andes, so always use sunblock.

Rainfall on the altiplano also varies with its west (dryer) - east (wetter) position, due to the effects of the Humboldt current. The climate of Titicaca is chilly, often with temperatures below 0 °C at night while rarely reaching comfortable temperatures in daytime. One should always have a sweater and a jacket at hand, as the temperatures my drop in minutes when a cloud moves in.

 

The larger towns in the Andes are not really at the altiplano but a bit lower, with Cusco and Arequipa being the largest Andes towns.

Cusco, located on the Southern hemisphere, has its winter from May to August, which is the dry season with blue skies and cold night, often falling to the freezing point. The winter, from December to March, is the wet season, when skies are often overcast, particularly in the afternoons. Day temperature vary little in Cusco, making the Cusco climate mild and comfortable. 

 

Machu Picchu lies at an elevation around 2400m, on the Amazon side of the Andes. As a result, it has a much warmer and wetter climate than Cusco. Even though average high temperatures don't seem to vary all that much, when the sun shines it will certainly feel quite hot. The hours of sunshine in these data seem rather optimistic for the rainy season.

Arequipa Climate

Arequipa lies at an elevation of around 2300 m, but at the coastal flanks of the Andes. As a result, the temperatures are lower than for instance at Machu Picchu, which lies at about the same elevation and the rainfall is considerably lower, while the dry season lasts much longer.
