What August is like in Atacama Desert

August is cool and clear, with days near 70F (21C) and cold, windy nights. The winter holidays are over, so crowds thin and prices fall again. Skies are excellent for astronomy, but strong winds can make evenings and exposed viewpoints feel much colder than the numbers suggest.

It suits stargazers and budget travelers who pack properly. Families can do well here too, with calmer tours and good value. Check road conditions for El Tatio before you go. If you would rather skip the wind and freezing mornings, September brings similar skies with warmer days.

Make the most of August

What is especially good about Atacama Desert this month.

The Milky Way still overhead

The Milky Way core is still overhead in the evening. Plan around the new moon for the darkest nights.

Quiet tours after the holidays

With school back in session, small groups and good prices return.

Clear dawn light at the Salar

Crisp mornings at Laguna Chaxa bring sharp reflections and flamingos feeding in the shallows.

What to pack for August

A windproof outer layer
A warm down jacket for nights
A buff to cover your face in the wind
Moisturizer and lip balm for very dry air

Our timing tip

Book stargazing for nights with a light wind forecast, since tours in calm air are both warmer and sharper.

Things to do in Atacama Desert

Full guide

Valle de la Luna

A valley of salt formations, dunes, and ridges. Sunset from the viewpoints is the classic experience; entry is limited, so book ahead in high season.

Tickets and tours →

El Tatio geysers

Leave San Pedro before dawn to see the geysers at their most active. It is freezing at that hour in any season, so dress in layers.

Tickets and tours →

Stargazing tour

Local operators set up telescopes outside town. Book on nights close to the new moon for the darkest skies.

Tickets and tours →

Laguna Cejar

A salt lagoon so dense you float, a short drive from San Pedro. Rinse off afterward; the salt dries fast.

Tickets and tours →

Altiplanic lagoons (Miscanti and Miniques)

Deep blue lakes below volcanoes at over 13,000 feet. Go after a few days acclimatizing in San Pedro.

Tickets and tours →

ALMA Observatory

One of the world's largest radio telescope arrays. Free public visits to the operations support facility run on weekends and must be booked in advance.

Official site ↗Tickets and tours →

Beat the crowds

Avoid Chile's summer holidays (January and February) and the July winter break, when San Pedro fills with domestic travelers.
Book stargazing tours for nights near the new moon; tours still run on full moon nights, but the stars are washed out.
Spend the first two days on lower-altitude trips like Valle de la Luna before tackling El Tatio and the high lagoons.
April, May, October, and November combine clear weather with lower prices and fewer visitors.

Know before you go

Summer storms in January and February can close roads and cancel tours to El Tatio, the high lagoons, and the Bolivian border.
Winter snow in June through August can close the high passes and routes to Uyuni.
Valle de la Luna and some other sites are managed by local Indigenous communities or public agencies and may close on certain days or have capped entry.
ALMA public visits run only on weekends and require advance booking.
