Sechura Desert
Piura
The Sechura Desert is a large coastal desert located along Peru's northern Pacific coast, primarily within the Piura and Lambayeque regions. Spanning approximately 5,000 square kilometers, it extends from the coastline inland to the foothills of the Andes Mountains. Its extreme dryness is caused by the upwelling of cold coastal waters and subtropical atmospheric subsidence, making it one of the most arid deserts on Earth. Despite its aridity, the desert experiences occasional flooding during El Niño years, notably in 1998 when a vast temporary lake formed, covering an area roughly 145 kilometers long. The desert includes the Bayóvar Depression, the lowest point in Peru and the Southern Tropics. Historically, the region was home to advanced pre-Columbian cultures such as the Moche and Sican, who thrived along the short rivers that cross the desert. Today, these rivers support intensive irrigation-based agriculture, sustaining major urban centers like Piura and Chiclayo. The climate features warm, sunny summers with temperatures exceeding 35°C and cooler, cloudy winters. The desert’s unique combination of coastal and Andean influences creates a distinctive natural and cultural environment.
