The National Study of the El Niño Phenomenon (ENFEN) in Peru has officially declared a state of alert due to the anticipated Coastal El Niño phenomenon. This alert responds to increasing probabilities of its manifestation starting from March through November 2026. The phenomenon is characterized by potential warm sea conditions which could peak moderately by July, with neutral conditions expected in the central Pacific region until May.

The implications of the Coastal El Niño are significant, affecting sea temperatures, rainfall patterns, and wind dynamics along the coastal regions. Based on the latest estimates, different areas are likely to experience varying weather patterns, with the North Coast projected to see rainfall ranging from normal to above-normal from February to April. As the months progress, predictions indicate an increase in the likelihood of moderate to heavy rainfall between March and April, coupled with elevated temperatures in the region.

Overall, the alert highlights the critical nature of monitoring climate phenomena in the Pacific coastal regions, as their impacts can lead to substantial environmental and economic consequences. Stakeholders, including local authorities and regional planners, will need to prepare for potential disruptions caused by this climatic phenomenon, ensuring that necessary measures are in place to mitigate impacts on communities and ecosystems.
