The 1925-26 El Niño phenomenon caused significant disruptions in Peru, leading to the collapse of anchovy populations and devastating floods. This major climatic event warmed Pacific waters, severely impacting fisheries and local economies reliant on fishing. The resulting droughts in other regions highlighted the far-reaching effects of El Niño on global weather patterns. The crisis underscored the vulnerability of communities to climate variability and the importance of understanding environmental changes.

The El Niño phenomenon that devastated Peruvian fisheries in 1925-26 was reflected in Latin American poetry, which explored themes of marine ecosystems and human vulnerability. Poets like César Vallejo captured the emotional and environmental impact of such natural disasters on communities.
