Bolivia's Weather: Best Times To Travel And Explore

The best time to visit Bolivia is during the dry season, from May to October, especially if you're interested in hiking, trekking, climbing, or other outdoor activities. During the dry season, days are generally shorter, but when the sun is out, it's shining brightly and trails are easy to navigate. The dry season is also the high season for tourism, so some prices will be higher and attractions busier. The start (April-May) and end (October) of this dry season are particularly good times to go, as there are fewer crowds. The eastern lowlands, including Santa Cruz and the Amazon, enjoy warm temperatures year-round, with lows of 15°C and highs of 31°C.

Dry season (May to October)

The dry season in Bolivia is from May to October and is the best time to visit the country, especially for those interested in hiking, trekking, climbing, and other outdoor activities. During these months, the days are generally shorter, but the sun is bright, and the trails are easy to navigate. This period is also ideal for visiting the Uyuni Salt Flats, as the lack of rain makes travel much more convenient and reliable.

The dry season in Bolivia varies by region. In the highlands, including the Altiplano (La Paz, Uyuni) and the central Bolivian mountain chain (Potosí, Sucre, Cochabamba), the dry season brings cold temperatures, with highs of 15°C-19°C and lows well below freezing at night. The southern Altiplano is the coldest and most exposed region, with temperatures in the desert dropping to below -20°C at night during June and July. The dry season is also a good time to visit the Bolivian Amazon, as the humidity drops and the temperatures are pleasantly cool, frequently reaching 30°C. However, cold spells called surazos can blow in from the south, causing temperatures to drop to 12°C overnight.

The dry season in Bolivia is the most popular time for tourism, with the highest number of visitors in July and August. August is Bolivia's Independence Day on the 6th, so expect heavy demand for hotels and tourist services and a small hike in prices. The dry season is also an excellent time for trekking and exploring the ruins of Bolivia's decorated past, such as the Jesuit Mission towns in the lowlands of Bolivia.

The dry season in Bolivia is a great time for travelling around the country, as road travel is easier and there is less travel disruption. This is especially important when visiting the Salt Flats and Lake Titicaca, as the bright sunny conditions provide dazzling blue skies for photographs. However, it is essential to plan well in advance during the peak season from June to September to secure the best choice of accommodation.

Wet season (November to March/April)

The wet season in Bolivia is from November to March or April. During this time, the country experiences warmer temperatures and more humidity, particularly in the lowlands. The wet season sees the highest amount of rainfall in Bolivia, with January to March being the rainiest months. This can cause some travel disruptions, especially from January onwards, as roads may flood and landslides are common. However, river travel becomes easier for adventurers. The wet season is also a great time to witness the famous mirror effect on the Uyuni Salt Flats, which occurs due to flooding.

The wet season in Bolivia is also a cultural journey, with several festivals and events taking place during this period. In January, La Paz hosts Alasitas, where locals purchase miniature items to offer as gifts to the Andean god, Ekeko. February is marked by the lively and colourful Carnival celebrations in Oruro and Santa Cruz. The religious holiday has been celebrated since the 18th century and is the country's most important national holiday. The festivities include a 4km-long procession with over 30,000 dancers and musicians, reenacting battles between Good and Evil. The celebrations end with a giant water fight.

March is the harvest season in Tarija, Bolivia's main wine-growing region. It is also a good time to visit the Bolivian Amazon, as the humidity drops and the temperatures become more pleasant. The wet season is an excellent time for swimming, rafting, and kayaking in the crystal-clear rivers swollen by the increased rainfall.

Despite the rain, the wet season in Bolivia offers magical experiences, such as the mirror effect on the Salt Flats, and cultural festivities. However, travellers should be prepared for potential travel disruptions due to flooding and landslides and be flexible with their plans.

Spring (September to November)

Spring in Bolivia (September to November) is a ""shoulder season", meaning that the winter/dry season is coming to an end, but the rainy/wet summer season has not yet begun. During this time, travellers enjoy visiting Uyuni when the skies are clear and the weather is warm. However, tourists can also visit Uyuni in the rainy season from December to March if they want to see the famous "mirror effect" on the salt flats.

Bolivia's weather in spring reaches highs of 19°C in La Paz, 19°C in Uyuni, and as high as 36°C in Rurrenabaque, a small town on the Beni River in the Bolivian Amazon. Visitors can expect dry weather in areas like La Paz and Uyuni, while the Bolivian Amazon can experience some rain showers due to its tropical climate.

Spring is a great time to explore some of Bolivia's greatest historical ruins. Once the parading ground of the Inca empire, Bolivia is dotted with significant sites, from ancient statues and cities to natural landmarks like Lake Titicaca, which feature prominently in Incan folktales and legends. When rain levels are low during spring, sites like Isla del Sol and Tiwanaku can be fully explored and enjoyed under clear skies.

September is a great month to visit Bolivia as it still has the advantages of dry weather, but it gets less busy as the month progresses. This is also one of the best times to see vast numbers of flamingos in the lakes of the high Altiplano.

October is another good month to visit, as it is still dry but warmer, with spring approaching and crowds dispersing.

Summer (December to February)

Summer in Bolivia falls between December and February. This is the rainy season, so expect warm temperatures and frequent rainfall. December and January are the hottest months of the year in Bolivia, and the rainy season is in full force from December to March. This means that if you're travelling to Bolivia during December, January or February, you're likely to experience some rain showers throughout the day. However, the rain might be heavy for a couple of hours and then stop. The rainy season in Bolivia is not as extreme as monsoons in other parts of the world.

Bolivia's summer weather is hot and humid throughout the day and night. The temperature spikes during this period, and there are more frequent rain showers as it is still the rainy season. Uyuni, for example, reaches highs of 69°F (21°C).

The best thing to do during Bolivia's summer is to explore Salar de Uyuni and experience the vibrant local culture. From January, the Uyuni Salt Flats will be covered with rainfall, leaving a mirrored reflection that has made Uyuni famous internationally.

Summer in Bolivia is also a festive season, with certain destinations popular spots for witnessing the country's vibrant culture. In Oruro, February marks the start of the famous Carnival celebrations. This religious holiday has been celebrated since the 18th century and is the country's most important national holiday. In the days leading up to Easter, the quaint city streets of Oruro fill with colourfully decorated citizens and talented entertainers.

Bolivia's summer is also a great time to head north, where the flooded Uyuni salt flats present a mirror to the sky. Just make sure your timings are flexible in case there is any disruption to transportation due to flooding – January and February are the rainiest months and road closures are common.

Autumn (March to May)

March is the last month of the rainy season in Bolivia, with short, sharp downpours. The rain in the Andes usually ends by April, and the weather in the plains and rainforest becomes less humid and drier. In places like La Paz and Uyuni, the days will be dry, sunny, and cold. By May, the Andes will be in their dry season, with ideal travel weather. Humidity will continue to fall in the lowlands and around Santa Cruz de la Sierra.

Bolivia's weather in autumn remains warm, but humidity levels start to decrease. La Paz and Uyuni experience highs of 64°F (18°C). In Uyuni, temperatures can drop to lows of 19°F (-7°C) at night.

One of the best things to do in Bolivia during autumn is to explore the city of La Paz, where temperatures do not fall below 53°F (12°C). In May, La Paz has pleasant, mild weather, perfect for outdoor exploration of the city and its surroundings.

La Paz is the seat of government in Bolivia, with impressive national monuments like Plaza San Francisco and Plaza Murillo, with the presidential palace. The city is bursting with Bolivia's traditional culture, and in every square, you'll find "Cholas" (indigenous women of Aymara or Quichuan descent) selling handicrafts, clothing, food, and drink. The Andes surrounding La Paz offer innumerable hikes along ancient Inca trails to Sorata and Tiahuanaco.
