The World Meteorological Organization (WMO) has issued a warning on July 4, 2026, that the El Nino climate phenomenon is set to develop into a strong event, increasing the likelihood of extreme weather globally. The agency cautioned countries to prepare for potential impacts as El Nino conditions rapidly intensify.
Understanding El Nino's Impact
El Nino refers to the warming of surface temperatures in the central and eastern equatorial Pacific Ocean, which disrupts global weather patterns. The WMO's monthly Global Seasonal Climate Update predicts a swift transition to a strong El Nino event between July and September 2026.
El Nino events occur every two to seven years and can last from nine to twelve months. The WMO categorizes these events into four levels: weak, moderate, strong, and very strong. The current forecast indicates that this El Nino will reach the third-highest classification.
Global Weather Changes Ahead
As El Nino strengthens, it is expected to cause significant changes in wind, pressure, and rainfall patterns worldwide. WMO climate scientist Alvaro Silva noted that there is heightened confidence in the development of strong El Nino conditions, stating, "El Nino conditions have developed in the tropical Pacific and are forecast to strengthen rapidly over the coming months, increasing the likelihood of extreme weather events in many parts of the world."
The WMO highlighted the risks associated with this phenomenon, including heatwaves and heavy rainfall. The organization aims to enhance early warning systems to assist vulnerable sectors such as agriculture and health in preparing for the anticipated impacts.
Temperature Projections and Regional Effects
Forecasts suggest that seasonal-average sea-surface temperature anomalies could exceed 2°C in key monitoring regions. The WMO's predictions indicate that above-average temperatures will likely affect most land areas between 60 degrees south and 60 degrees north, impacting nearly all populated regions.
Specific regions are already experiencing the effects of El Nino. For instance, Tegucigalpa, the capital of Honduras, is facing severe drought conditions. The rainfall outlook from July to September aligns with a strengthening El Nino, predicting above-normal rainfall in the southwestern United States while forecasting below-normal rainfall across the Indian subcontinent and much of Australia.
Peru has declared a 60-day state of emergency across 800 municipalities due to the imminent danger of heavy rains linked to El Nino, warning over 9.3 million people of high risks for flooding and landslides.
