Weather in Peru

Are you going for a walk or planning a journey? Here you will find the most up-to-date information about the weather in Peru, including detailed forecasts and visual charts for your convenience.

The climate in Peru can be characterized as temperate, with a distinct change of seasons. The weather here is typical for the continental United States: travellers will not face the extreme heat of the tropics or harsh polar cold, yet the differences between winter and summer months are quite perceptible. This allows tourists to enjoy a variety of seasonal activities.

Summer in the city is usually warm and comfortable, with average temperatures around +22...+24°C, which is ideal for walks and active leisure in the fresh air. Winter, however, brings coolness and regular frosts: in January and February, the temperature often drops below zero, so warm clothing will be required for a trip during this period.

A characteristic feature of the local climate is the stability of precipitation throughout the year. In Peru, there is no distinct "dry" season or rainy season — cloudy or rainy days occur with notable regularity (on average 10–13 days per month) in both summer and winter. When planning a visit, it is worth always keeping an umbrella with you, regardless of the calendar date.

Climatic conditions in the city of Peru are distinguished by pronounced seasonality, offering tourists a variety of temperature regimes. The coldest time of the year is winter, especially January, when the average temperature drops to -1.6°C, and night frosts can reach -5°C. February and December are also characterized by cool weather, often balancing around the freezing mark, so warm clothing will be required for a winter trip.

Summer, on the contrary, delights with warmth and comfortable conditions for relaxation. The hottest month is traditionally considered to be July, with an average figure of 24°C and daytime maximums approaching 29°C. June and August support this trend, maintaining pleasant warmth in the range of 22–23°C. Such weather allows one to enjoy time in the fresh air without the stifling heat characteristic of more southern regions of the USA.

Spring and autumn serve as periods of smooth transition. In May and September, mild and pleasant weather sets in, with the air warming up to 20–25°C during the day. It is worth considering daily temperature fluctuations: throughout the year, the difference between the daytime maximum and nighttime minimum averages from 5 to 10 degrees. This means that even after a warm summer day, the evening may bring perceptible freshness.

Precipitation in the city of Peru is distributed quite evenly throughout the year, so travellers should be prepared for weather changes in any season. In winter, when the average temperature stays around or below zero, snow often falls here. In December, January, and February, 10 to 11 days with precipitation are recorded, creating an atmosphere characteristic of the cold season.

With the arrival of spring, snow is replaced by rain, and the frequency of precipitation gradually increases. May can be called the cloudiest month of the year: statistics show up to 14 days with precipitation. In summer, rains are also a frequent occurrence, especially in July and August (about 12 rainy days), however, thanks to the warm weather, they usually do not interfere with walks for long.

Autumn brings a slight decrease in the frequency of rains. September and November are considered some of the "driest" months in terms of the number of inclement days — their number drops to 9. Nevertheless, when setting off to this city in the USA, it is recommended to always have an umbrella with you, as absolutely arid periods practically do not occur here.

When preparing for a trip to Peru, it is important to consider the pronounced seasonality of this region. Winters here can be frosty, with temperatures dropping below zero, so during the cold season, you will definitely need a warm jacket or down coat, a hat, a scarf, and gloves. Spring and autumn are often characterized by changeable weather, so it is best to use the principle of layering: wear a t-shirt, a jumper, and outerwear so that if it gets warmer, you can easily remove the extra layers.

Summer in this corner of the USA is usually warm and pleasant, with average temperatures around +24°C, which is ideal for light clothing made from natural fabrics, shorts, and t-shirts. However, even in the summer months, evenings can bring coolness, so a light windbreaker or cardigan in your suitcase will not be superfluous. Also, do not forget sunglasses and sunscreen to protect yourself during long walks on sunny July and August days.

Particular attention should be paid to protection from moisture, as statistics indicate regular rainfall throughout the year (on average 10–14 days with precipitation per month). A compact umbrella or a high-quality raincoat will be indispensable items in your luggage. For comfortable sightseeing, choose comfortable, preferably waterproof flat shoes that will allow your feet not to get tired during long walking routes.
