Weather Peru is located into the tropical belt and near to the equatorial line, but its weather is not as it is supposed to be for this area. Apart from the tropical weather, this country has a range of weathers and climates that make it so diverse and different from other countries. In the world, you can find a total of 32 kinds of climate and Peru has 28 of them (87.5% of the total!). In other words, a trip through Peru can signify to come across with hot deserts, dry forests, humid savannas, plain rainforests, cold plateaus, cool steppes and icy mountains. As a way to explain its average weather we can say that in the time of the typical northern hemisphere summer, in Peru you will have winter in the coast, and summer in the Andean highlands and the jungle. In the opposite, winter in northern hemisphere, you will have in Peru a rainy season in the Andes and the jungle, but a hot summer all over the coast. The following chart can help you to understand how the Peruvian weather "works":   WEATHER BRIEF Average Temp. Dry season (May-Sep) Rainy season (Oct-Apr) The Coast 0-1,500 masl 14-27°C Cold wet days Cold wet nights Hot days Cool nights The Andes 1,500-6,768 masl 9-18°C Warm dry days Very cold nights Rainy days Rainy cold nights The Jungle 1,500-84 masl 25-30°C Hot wet days Fresh nights Rainy cool days Rainy fresh nights In the other side, the typical four seasons in the south hemisphere are: - Spring : September 23 - December 21 - Summer : December 22 - March 21 - Autumn/Fall : March 22 - June 21 - Winter : June 22 - September 22 In the "middle" of these seasons there can be different weather conditions, sometimes an extension of one of them for some months or unpredictable days because of a mixture of these ones. But how is it possible to have this "marmalade" of weathers at the same time in only one country? The answer lies in the geographical configuration of Peru. The Andes mountain range and the Humboldt sea current (or Corriente Peruana) produce both a big change in the tropical weather it should have. The Andes, which run longitudinally, break the country in two parts: the desert Coast and the Amazonic jungle. Then, this mountain range acts as a natural barrier between both and creates also a new region by itself. Winds from the jungle are unable to reach the coast, keeping it dry. The Humboldt is a cold current that comes from the southern seas. In the north of Peru it mixes with the warm current called "El Niño". This event makes the Peruvian coast and sea to present different temperatures and conditions. The weather in the Coast is generally temperate and dry. In the north, it is warm with considerable rain in the summer. In the central and south coast, the weather is colder than the north and drizzle is present in the winter in certain cities. The Andes area, also known as sierra has a cold and dry weather on an average. When it rains, this is stronger in the nortern Andes. The Andean rain causes severe landslides. The Amazonic rainforest has an evident tropical weather; hot, humid and rainy, especially in the summer. In this season, raining increases to a large extent, causing floods in low areas.
