The Amazon Jungle

South America is a huge continent and climatic conditions vary widely. In June, when it’s freezing cold at the southern tip of Argentina, it’s hot and humid in Venezuela. You can take into account, however, that more than 75% of the continent sits south of the Equator, which means that winter usually lasts from June through September and summer from December through March. In high-altitude cities, such as Quito, you can expect cool weather year-round; in the Amazon basin region — in the center of the continent, from Ecuador to Brazil — the weather is hot and humid year-round.

In general, the high season for travel in South America lasts from June through September, from mid-December through mid-January, and during Carnaval, which takes place the week before Ash Wednesday.
