The city is located in the extreme west of Brazil, in the state of Acre, at 7 degrees south latitude and 200 meters (650 feet) above sea level. We are in the Amazon rainforest. Just to the south of the city flows the Juruá River, a tributary of the Amazon River. In February 2021, during particularly heavy rains that can sometimes occur in the austral summer, the river flooded the city.
It is generally hot even in the austral winter, however, cool air can sometimes arrive from the south, bringing daytime temperatures around or below 20 °C (68 °F). For example, in July 2010, when it snowed in Buenos Aires, there were a few cool days, and in particular, a rainy day, with a minimum of 13 °C (55 °F) and a maximum of 14 °C (57 °F).
