The World Meteorological Organisation (WMO) has issued a stark warning that El Niño conditions will intensify beginning in August 2026, reshaping global weather patterns through the rest of the year. According to the WMO’s Global Seasonal Climate Update, sea surface temperatures in the central and eastern Pacific Ocean are expected to rise sharply, with anomalies exceeding 2.9°C above normal levels. This marks the onset of a strong El Niño event that will have far-reaching consequences.
Global Impact
El Niño is one of the most influential climate phenomena, occurring every two to seven years and typically lasting nine to twelve months. Its intensification is expected to bring above-normal temperatures across most land areas, while rainfall patterns will shift dramatically. Some regions will face droughts, while others may experience floods and heightened wildfire risks. The WMO has emphasized that this event is developing against the backdrop of record ocean heat and rising global temperatures, amplifying its potential impact.
India’s Outlook
For India, the strengthening El Niño combined with a positive Indian Ocean Dipole (IOD) is likely to result in below-normal monsoon rainfall during August–October 2026. The India Meteorological Department (IMD) has already projected weaker rainfall and above-average temperatures for this period. This could stress water supplies, reduce agricultural output, and impact rural livelihoods. Farmers, in particular, may face challenges in crop planning and irrigation as rainfall deficits coincide with rising heat.
Climate Risks and Warnings
UN Secretary-General António Guterres described the situation vividly: “El Niño is not just on our doorstep – it is inside the house and turning up the heat. This is only a warm-up act.” He warned that fossil fuel expansion continues to exacerbate climate risks, and without urgent action, the dangers will become deadlier. The WMO has urged governments to strengthen early warning systems and prepare for extreme weather events, particularly in vulnerable regions.
What Lies Ahead
The intensification of El Niño is expected to last well into 2027, shaping weather patterns across Asia, Africa, and the Americas. For India, the coming months will be critical in managing agricultural strategies, water resources, and disaster preparedness. Globally, the event underscores the urgent need to address climate change drivers and build resilience against increasingly volatile weather systems
