Weather in Tacna

To ensure your trip to the city of Tacna is as comfortable as possible, familiarise yourself with the latest weather update. Below, you will find current weather data, detailed forecasts, and convenient charts.

The climate of Tacna can be described as desert and arid, yet surprisingly mild and comfortable for travellers. Located in southern Peru, the city enjoys stable weather almost all year round. Thanks to its unique geographical position, there is no extreme exhausting heat or severe cold here, making a trip here pleasant in any season.

The temperature pattern is characterised by smoothness and predictability. The warmest months fall between January and March, when daytime temperatures reach a comfortable +24...+25°C. Winter (from June to August) is quite nominal here: during the day the air warms up to +19...+20°C, while nights become fresher, with temperatures around +13...+14°C. This time of year is excellent for long excursions without the risk of overheating in the sun.

The main feature of the weather in Tacna is the almost complete absence of significant precipitation. Rain here is an extremely rare and often negligible phenomenon; even in the summer months, when the highest number of "wet days" is recorded, the volume of rainfall remains minimal. Travellers should expect dry weather, so an umbrella in your suitcase is unlikely to be useful, but sunscreen will always be relevant.

The climate in Tacna is distinguished by enviable stability and comfort, making this city a pleasant travel destination at any time of year. The warmest period here falls at the beginning of the calendar year — from January to March, which corresponds to the local summer. During these months, the average air temperature holds at +21°C, and at the height of the day, the thermometer often reaches the +25°C mark. February is traditionally the hottest month, however, thanks to the dry climate, the heat is tolerated easily and does not feel like sweltering sultriness.

With the onset of the Southern Hemisphere winter, which lasts from June to August, the weather becomes fresher but remains very mild compared to the habitual European cold. The average daily temperature at this time drops to +16°C...+17°C. July usually becomes the coolest month, when night-time readings can drop to +13°C... +14°C. Nevertheless, even in winter, the days remain warm enough for walks: the air warms up to +19°C...+20°C, so a light jacket or sweater will be quite sufficient.

A characteristic feature of the local climate is the moderate temperature difference throughout the day. The difference between the daytime maximum and night-time minimum is usually about 6–7 degrees. This means that even after the warmest summer day, a pleasant coolness sets in (around +17°C), ensuring comfortable sleep. In general, Tacna lacks extreme temperature fluctuations and frosts, creating favourable conditions for tourism all year round.

Tacna is characterised by an extremely arid climate, which is typical for the desert coast of Peru. It is difficult to single out a classic rainy season here, as significant precipitation is a great rarity for this region. Even in the "wettest" months, considered to be January, February, and March, the average rainfall level is only about 1 mm, despite statistics recording from 8 to 11 days with precipitation. Most often, this manifests not as a downpour, but as dense fog or light drizzle, characteristic of the Pacific coast.

The rest of the year, especially the period from April to November, is characterised by an almost complete absence of rain. In months such as April, September, and October, the amount of precipitation tends towards zero, and the number of rainy days is non-existent. Travellers are unlikely to need an umbrella during a trip to Tacna, however, it is worth being prepared for dry air and desert landscapes.

Tacna welcomes travellers with a mild desert climate where extreme heat or cold is a rarity. In the summer months (from January to March), when the air warms up to a comfortable +25°C, light clothing made from natural fabrics, such as cotton or linen, will be useful. Although rainfall volume is minimal (only about 1 mm), it can be overcast and humid during this period, so a light windbreaker will not go amiss.

From June to September, it becomes cooler, and the average temperature hovers around +16…+17°C, dropping to +13°C at night. For this time of year, the layering principle is the ideal solution: during the day you can walk in a t-shirt or long-sleeved top, but for the evening, be sure to grab a warm sweater, fleece, or jacket. Evenings in this region can be quite fresh, so an insulated layer of clothing will ensure your comfort after sunset.

Regardless of the season, the sun in this part of the country can be active, so be sure to pack sunglasses, headwear, and high SPF sunscreen in your suitcase. Since rain in Tacna is an exceptional phenomenon and there is practically no precipitation for most of the year, you are unlikely to need an umbrella. However, comfortable, worn-in walking shoes are simply essential for comfortably exploring the city streets and sights.
