Here, the geography works against them. Furthermore, the Humboldt Current, a cold upwelling from the depths of the Southern Ocean, chills the waters off the northern coasts of Peru and Ecuador.
How South America's Geography and Ocean Currents Block Hurricanes
Historical Exceptions Prove the Rule More perspective on Why don't hurricanes hit south america can make the topic easier to follow by connecting earlier points with a few simple takeaways. The coastline is bathed by the South Equatorial Current, which pushes warm water westward, but this current does not extend far south along the coast.
The system would likely remain a disorganized cluster of thunderstorms, unable to achieve the symmetry and power characteristic of a hurricane. As storms move westward from Africa or the Caribbean, they eventually encounter the coastline of northern South America.
How the Humboldt Current and Geography Keep South America Hurricane-Free
Consequently, even if a disturbance were to form near the northern tip of South America, the physics required to fuel the storm’s intensification are largely absent. The presence of strong upper-level winds over the eastern Pacific and South America disrupts this symmetry, causing the storm to elongate and dissipate.
