What July is like in Atacama Desert

July is the coolest month in the Atacama. Days are sunny and near 68F (20C), but nights fall well below freezing. Chile's winter school holidays bring more domestic visitors, so San Pedro gets busier and prices rise. Snow can close the high passes to Bolivia and some altiplano roads, so trips to Uyuni and the high lagoons are less certain.

It is a shoulder month. It suits stargazers who want the Milky Way overhead and do not mind cold, and families tied to the July break. If you want the high country with more certainty and fewer crowds, go in May, September or October instead.

Make the most of July

What is especially good about Atacama Desert this month.

Winter stargazing

Long, dark, dry nights give telescope tours plenty of time. Dress as if for a ski trip.

Snow on the volcanoes

The peaks above the Salar de Atacama often wear snow caps, which makes for great photos from the lower flats.

Warm afternoons in town

Midday is pleasant in the sun, a good time for the Salar de Atacama or a slow lunch.

What to pack for July

A heavy insulated jacket
Thermal layers, top and bottom
Warm gloves, a beanie and a neck gaiter
Sunglasses for glare off snow and salt

Our timing tip

Check road status with your tour operator the evening before any El Tatio or lagoon trip, since snow closures can happen overnight.

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.

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.
