Varied Topography

Another factor that drastically influences South America’s climate is its varied topography. You’ve heard about the chilly peaks of the Andes, the largest mountain range in the world and one of the principal features of the continent’s topography. Altitude changes climate, often making it cooler the higher you go. This explains why cities like Medellin are known as ‘the city of eternal spring’, while there are ski resorts in the Andes.

On the flip side, expansive lowland areas like the Amazon Rainforest have consistently high temperatures due to their proximity to the equator and low altitude. Here, you’ll find a tropical rainforest climate, characterized by high humidity and rainfall.

As you plan your South American adventure, these key factors—size and location, varied topography—play an instrumental role in determining where you’ll find hot weather, where it’ll be cool, and where you’ll encounter an array of climates in between.

Tropical Climate in the Amazon Rainforest

Venture deeper into South America and you’ll encounter the world’s largest tropical rainforest, the Amazon. This region showcases the intensity of a tropical climate firsthand, where rain is the norm, not the exception. The Amazon Rainforest sprawls over six million square kilometers, covering large portions of Brazil, Peru, and Colombia.

In this vast expanse, the temperatures aren’t extreme, typically ranging between 80 and 90 degrees Fahrenheit throughout the year. But don’t be fooled, it’s the humidity that will get you. Usually hovering around an oppressive 80%, the humidity can make it feel much hotter than it actually is, turning the rainforest into a gigantic natural sauna. This high humidity aspect is a crucial part of maintaining the lush, vibrant ecosystem that is the Amazon.

These characteristics contribute to an intense cycle of evaporation and rainfall. Expect rainfall every day, with the heaviest showers occurring in the afternoon. The Amazon region receives an impressive 60 inches of rainfall annually – almost double the global average.

With this rainfall comes a vibrant variety of plant and animal life, so you’ll likely want to get out there and explore. But remember, you’re in a tropical rainforest. It’s hot, humid, and you’ll likely get rained on. So, consider packing light, breathable clothes, bug repellish, and maybe even a poncho or light rain jacket.

As part of your South America adventure, a journey into the Amazon Rainforest presents an exciting opportunity to experience the tropics as nature intended. It’s this hot, humid weather that makes the rainforest what it is, a diverse biosphere teeming with life. While this weather may seem daunting, it’s the key to the ecosystem’s success, nurturing a verdant habitat where thousands of unique species flourish. So, gear up and get ready to experience the tropical climate of the Amazon Rainforest up close.

The Andes Mountains: A Contrast in Climate

As you journey out of Amazon and move further west, the Andes Mountains welcome you. This colossal mountain range stands as the world’s longest overland mountain range. It extends over seven South American countries; this diversity contributes to a wide array of climates and weather conditions.

Every climate in the Andes is unique. You can travel from the hot, arid deserts to the cold, snow-capped mountains within a few hours. Altitude plays a significant role in this climate change. Lower altitudes represent a predominantly warm, semi-arid climate, whereas the temperature drops and precipitation increases as you ascend. At higher altitudes, you can expect temperatures that dip below the freezing point.

Traveling the Andes requires versatility in your wardrobe. Layered clothing is a smart move. Be prepared with warm clothing and waterproof gear if you’re tackling the higher altitudes. A well-planned trip to the Andes offers you various climates in one location!
