Strong El Niño Forecast June-Sept 2026; Below-Normal Monsoon Expected

The World Meteorological Organization (WMO) has forecast a strong El Niño episode during the June-September 2026 period, with associated prediction of below-normal monsoon rainfall across the Indian subcontinent. This carries significant implications for agricultural productivity, water availability, and economic growth.

Background: El Niño (warm phase of ENSO—El Niño-Southern Oscillation) typically suppresses monsoon intensity due to reduced temperature gradient between Indian Ocean and Pacific. India's monsoon (June-September) accounts for 80% annual rainfall; below-normal monsoon directly impacts kharif crop yields, hydroelectric generation, and groundwater recharge. Previous strong El Niño years (1997-98, 2015-16) caused agricultural distress and drought declarations.

Key Facts: (1) WMO strong El Niño probability high confidence, (2) Below-normal monsoon typically means 80-90% of LPA (Long Period Average), (3) Critical months: July-August (peak monsoon), (4) IMD to issue real-time forecasts and warning systems.

Why It Matters: (1) Food security vulnerability (40% workforce in agriculture), (2) Rural distress increases farmer suicides risk, (3) Water stress impacts urban water supply, (4) RBI inflation expectations rise (food price inflation), affecting monetary policy.

Exam Angle: UPSC Mains (Climate, Agriculture, Water Resources), Prelims GK. Questions on: El Niño mechanism, monsoon variability, agricultural vulnerability, climate adaptation, seasonal forecasting, food security policy.
