It is part of a larger climate system called the El Nino-Southern Oscillation (ENSO), which also includes its opposite phase, La Nina. It is a natural climate phenomenon in which the surface water of the central and eastern Pacific Ocean becomes warmer than usual. This warming disrupts normal weather patterns across the world, leading to extreme events such as droughts, floods, and heatwaves. It influences agriculture, water resources, food security, energy demand and disaster risks across many regions.<\/span><\/p>\n<h2><strong>What is El Nino?<\/strong><\/h2>\n<p>El Nino is the warm phase of the ENSO which is one of the world&#8217;s most important natural climate patterns. It develops when sea surface temperatures in the central and eastern equatorial Pacific Ocean become unusually warm, changing global wind systems and rainfall patterns. It normally occurs every two to seven years and lasting about nine to twelve months. Its effects depend on intensity, duration and interaction with other climate systems such as the <a href=\"https:\/\/vajiramandravi.com\/current-affairs\/indian-ocean-dipole\/\" target=\"_blank\"><strong>Indian Ocean Dipole<\/strong><\/a>.<\/p>\n<h2><b>El Nino 2026<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">El Nino Weather conditions strengthened during 2026, with global agencies warning of widespread weather disruptions, higher temperatures and changing rainfall patterns.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">WMO Forecast: The <strong><a href=\"https:\/\/vajiramandravi.com\/current-affairs\/world-meteorological-organization\/\" target=\"_blank\">World Meteorological Organization (WMO)<\/a><\/strong> estimated an 80% probability of El Ni\u00f1o during June-August 2026, with the likelihood rising to 90% or more of continuing until at least November 2026.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Ocean Monitoring: Observations during late April to mid-May showed sea surface temperatures in the central-eastern equatorial Pacific approaching El Nino thresholds.
