Peruvian weather overview

First, we will say that Inca’s country has four sparse seasons during the year.  The summer in Peru begins on December 22 and until March 21. The autumn is from March 22 until June 21. The Winter is from June 22 to September 22 and the Spring begins from September 23 until December 21.

Also, Peruvian weather and its different characteristics are determined by three factors: The Peruvian Andes, the Humboldt ocean current coming from the south, and the El Niño air stream coming from the north, all of them mixed over the Peru region. These factors cause a variety of micro weathers and sensations in every department of Peru.

The Peruvian coast

The coast is a thin strip that runs along the entire Peruvian coastline and is washed by the waters of the Pacific Ocean. On its lands are located the Peru beaches, ports, boulevards, peninsulas, bays, cliffs, and desserts. The Peruvian weather in this part usually presents an arid climate, warm and dry, with average temperatures between 60-81ºF. This means a warm sensation despite having cloudy Skies and grays for the most part of the year. This is due to the Humboldt ocean current, a flow of cold water coming from the Antarctic that washes the entire coast of Chile and Peru, cooling the lower layers of the atmosphere and avoiding the creation of vertical air currents, which necessary to have rains and are the origin of gray clouds and haze along the entire coast, except the north.

On the coast north (Piura – Tumbes), the Peruvian climate can present an average of 64ºF in the coldest month (August) and 75ºF on average in the hottest month (February). In other words, it is the hottest part of the country. This is due to two factors, the first one is that the zone is closest to the equatorial line, the most tropical area in the world. The second factor is the Niño (Boy) Coastal Stream, a warm periodic current (2 – 7 years) that comes from Central America and bathes the coasts of Ecuador and the north of Peru. The beaches located there present clear skies, perfect waves, and warm breezes most of the year. In other words, the most perfect Sunset in Peru can be enjoyed there.

On the central coast (Lima – Trujillo), the Peru weather presents an average temperature between 63 – 73ºF. This zone is known for its cloudy skies and cloudiness from April to November. It is from December to March, summer when the skies usually clear. There are located in the capital of Peru and essential cities like Trujillo. A sensation of heat and dryness in summer and cold and wet the rest of the year.

South coast, (Ica – Arequipa – Tacna) presents a Peruvian weather average of 59 – 72 °F. The zone shows clear skies, and warm breezes most of the year, with rare precipitations. Here, you can visit the Paracas National Reserve, the Ballestas islands, the Huacachina oasis, the Mollendo beaches, and the awesome Nazca lines.

The Sierra of Peru

The Peruvian Andes cross the territory from north to south, separating the Coast (west extreme) from the jungle (east extreme) There, the Peruvian weather varies according to altitude and the slope, being the rainy season from September to May and the dry season from June to August. During the days, the sun’s rays usually are strong, causing hot days. However, the nights are clear and, being located at a higher altitude and far from the equator, usually, their temperatures drop to below zero. Therefore, the average temperature goes from 32 to 77ºF. Warm clothes are always recommendable because you can always find a cold breeze and some quite inconvenient rains all year. Other clothes like a rain jacket, trekking shoes, light pants, and some t-shirts cannot be overstated.

During the dry season, the average temperature goes from 68 to 77ºF. On the other hand, the rainy season presents temperatures from 64 to 68ºF. At night, the weather can down to 32ºF. The main cities located in the Andes are Cusco, Puno, Arequipa, and Ayacucho, among others. If you want to visit any of these popular tourist destinations in Peru, we recommend doing it in a range from April to October, summer in the highlands. Where you will find clear skies, strong rays of sunshine, and a mild climate. Otherwise, Winter is going from November to March and you can feel heavy rains, cloudy days, and powerful lightning. Therefore, you have to be patient with the flight delays, the strong rains at night, and the altitude sickness in the mornings.

The Peruvian Amazon

Visit the Amazon in Peru is one of the best experiences that visitors can have. Therefore, knowing the jungle weather to face during your visit is important. The Peruvian Amazon is located in the eastern end of the country and its basins are formed by tropical hills and plains, which makes them almost impenetrable. So walking through its foliage will guarantee an unforgettable adventure. The jungle area presents two seasons, like the Peruvian Andes; the rainy season from November to March with torrential rains and a humid climate is one of them. The other one begins from April until October, and it is called Dry Season. However, some heavy rains can occur all the year. The temperature ranges from 47ºF to 83ºF. Therefore, if you want to know about the Machu Picchu weather, pay attention to our section on South Amazon.

The north Amazon is located closest to the Equatorial line, for this reason, the weather is more humid and warm during the year, with frequent rains and electric storms. This region is extended from the Loreto region to Ucayali. Precisely in this part, the Amazon River runs toward Brazil. Here you can visit the Pacaya – Samiria National Reserve with a great variety of flora and wild fauna like jaguars, black caimans, monkeys, and snakes among others. Iquitos, and Pucallpa, among other interesting Jungle cities.

Despite having rains during the year, these decrease between May and September. The temperature in winter usually descends until 59ºF.

The best moment to visit Peru

Attractions situated on the Jungle area can join to this period of time. On the other hand, if you enjoy of fresh climate, walking over puddles, and seeing astonishing storms, the rainy season (from November to March) is for you.
