Best Time to Visit Bolivia: Month by Month, and the Salt Flat Problem
The best time to visit Bolivia depends on one trade-off: the Uyuni mirror needs the wet season, the open roads need the dry one.
This is the reasoning we use when we date a trip, not an article written to fill a blog. The Bolivia itineraries it feeds are here.
The short answer is May to October, the dry season. But that answer hides the one decision that actually changes your trip, so read the next paragraph before you book anything.
The trade-off nobody tells you about
Bolivia’s most photographed sight is the Uyuni salt flat under two centimetres of water, reflecting the sky like a mirror. That mirror only exists in the wet season, roughly December to March.
The dry season everyone recommends is exactly when the mirror is gone.
So the real question is not “when should I go to Bolivia”. It is “which Bolivia do I want”:
| Where | Wet season, Dec–Mar | Dry season, May–Oct |
|---|---|---|
| Uyuni | Mirror effect | White hexagons, no reflection |
| Driving on the salar | Can be restricted in wet years | Fully crossable |
| La Paz and the altiplano | Wet, green | Clear, cold nights |
| Amazon lowlands | Wettest months | Driest months |
| Crowds | Fewer | Peak in July and August |
Most people who travel in July come home without the photograph they had in their head. That is worth knowing in advance, not afterwards.
The mirror comes with a condition. Water on the salar is also water on the tracks, and in wet years the authorities restrict where vehicles can go: in January 2022, after flooding, the Potosí regional government banned crossing the salar to Isla Incahuasi. It does not happen every year, but it is why a wet-season visit needs a flexible route. If you book an Uyuni salt flats tour for those months, ask how the route adapts.
Bolivia’s three climates
Bolivia is not one weather system, and the month that is right for the salt flat is not necessarily right for the rest of the country.
The altiplano: La Paz, Lake Titicaca and Uyuni. High, dry in winter and very cold at night. The Uyuni salt flat sits at 3,656 m, and Bolivia’s weather service, SENAMHI, recorded −20.7 °C at Uyuni in June 2022 and −21.2 °C in July 2024. The days in the same months are clear and bright; the nights are what you pack for.
The valleys: Sucre. Below the altiplano, with almost all the rain in summer: about 150 mm in January and 1 mm in July.
The lowlands: Santa Cruz, Trinidad and Rurrenabaque. The wettest part of the country. Trinidad averages about 303 mm of rain in January and 36 mm in July; Rurrenabaque, the gateway to Madidi, 272 mm and 81 mm. Winter here brings the surazo, a mass of cold air pushed north behind a cold front, which can drop temperatures sharply in Santa Cruz. It is a lowland phenomenon, not a salt-flat one.
A note on those rainfall figures. SENAMHI does not publish its 1991–2020 averages as numbers, and Bolivia is missing from the international set of climate normals. The figures above are the 1961–1990 station records held by Germany’s weather service. They are old, and they are the most recent monthly figures we could find published as numbers.
Best time to visit La Paz
La Paz follows the altiplano: dry and clear from May to October, wet from December to March. Two festivals are worth building around.
Alasita opens on 24 January, a fair of miniatures bought as wishes for the year ahead, on UNESCO’s list of intangible heritage since 2017.
Gran Poder, the city’s great folk-dance parade, takes place on Holy Trinity weekend, which moves with the church calendar and usually falls in late May or June. Check the year before you fix dates: in 2026 the parade was postponed to 1 August because of road blockades.
The weather matters less in La Paz than the way you arrive. That part is further down.
Bolivia rainy season and dry season, month by month
January. Wet. The salt flat mirrors. Alasita opens in La Paz on 24 January.
February. Still wet, and the safest bet if the mirror is the reason you are going. Copacabana, on Lake Titicaca, celebrates the Virgen de la Candelaria on 2 February. The Carnival of Oruro, proclaimed by UNESCO in 2001, holds its main weekend on the Saturday and Sunday before Ash Wednesday, usually in February.
March. The end of the wet season.
April. The transition, and quietly one of the best months. Some water still on the salar, green altiplano, and the rain mostly finished.
May and June. The dry season settles in: cold, clear and bright. Gran Poder usually fills La Paz in one of these months. 21 June, the Aymara New Year, has been a national holiday since 2009.
July and August. The coldest nights and the busiest weeks. Nights on the salar drop well below freezing, which surprises people who packed for South America rather than for 4,000 metres. August is also festival month: the Virgen de Copacabana on 5 August, Independence Day on 6 August, and Urkupiña in Quillacollo, near Cochabamba, from 14 to 16 August.
September and October. Dry, warmer, fewer people. Our own favourite window, and the one we book most. In Sucre, the festival of the Virgen de Guadalupe, added to UNESCO’s list in 2025, runs from late August into September.
November. The first rains arrive. Unpredictable. We avoid committing anything fixed here. 2 November, the Day of the Dead, is a national holiday.
December. Wet season proper begins, and with it the mirror.
The part that has nothing to do with weather
Most of Bolivia sits above 3,500 metres. La Paz airport is at 4,061 m and it is one of the highest international airports in the world.
That matters more than the month. Arriving into La Paz directly from sea level puts you at altitude within an hour of landing, and the first forty-eight hours are usually wasted. Our guide to altitude in South America sets out why, with the numbers.
Coming overland from Peru, across Lake Titicaca, means you arrive already acclimatised. It is why our own itineraries run south rather than starting in La Paz, and it changes how the trip feels far more than choosing June over September.
Asked before booking
The questions we get on this
- When is the best time to visit Bolivia?
- May to October, the dry season, when the roads are open and the skies clear. The catch is the Uyuni mirror, which only exists in the wet season, roughly December to March. Choose by what you want to see: February for the reflection, or September and October for open roads with fewer people than July and August.
- What is the best month to visit the Uyuni salt flats?
- February, if you want the mirror effect: in the wet season a thin layer of water reflects the sky. Access can be restricted in wet years, as in January 2022, when flooding led the authorities to ban crossing the salar to Isla Incahuasi. To cross the whole salt flat and see its white hexagons, go in the dry season, May to October. April sits between the two.
- When is the rainy season in Bolivia?
- Roughly December to March, with the first, unpredictable rains in November. The lowlands take the most: Trinidad averages about 303 mm of rain in January against 36 mm in July, on 1961 to 1990 records. The same rain creates the Uyuni mirror, so the wet season is not simply the bad season.
- Is April a good time to visit Bolivia?
- Yes, it is quietly one of the best months. April is the transition out of the wet season: the rain has mostly finished, the altiplano is still green and there is often some water left on the Uyuni salt flat. It also comes before the busy months of July and August.
- Is July a good time to visit Bolivia?
- It is dry, clear and bright, with the roads open, but it is also cold and, with August, the busiest month. Nights on the salt flat drop well below freezing, and the Uyuni mirror is gone, so travellers expecting the reflection come home without that photograph. September and October are still dry and less crowded.
- How cold does the Uyuni salt flat get at night?
- Well below freezing on dry-season nights, from May to August. Bolivia's weather service recorded −20.7 °C at Uyuni in June 2022 and −21.2 °C in July 2024. The salar lies at 3,656 m, and the cold surprises travellers who packed for South America rather than for high altitude.
