What Happened
- The India Meteorological Department (IMD) has predicted the 2026 southwest monsoon will be "below normal," with rainfall forecast at 92% of the Long Period Average (LPA), carrying a model error of ±5%.
- The forecast comes with an elevated risk of El Niño conditions developing after June 2026, which historically suppresses Indian monsoon rainfall.
- The probability of a "deficient" monsoon (below 90% of LPA) is also assessed to be higher than normal — raising alarm for farm-dependent states.
- India's agricultural sector, particularly kharif crops such as rice, pulses, oilseeds, and cotton, faces potential output shortfall if the monsoon underperforms.
- A weaker monsoon typically feeds into higher food inflation, reduced rural demand, and pressure on government food security programmes.

Southwest Monsoon: Onset, Mechanism, and Agricultural Importance
The southwest (SW) monsoon is a seasonal wind system that brings warm, moisture-laden air from the Indian Ocean onto the subcontinent between June and September. It is driven by differential heating — the Indian landmass heats up much faster than the surrounding ocean during summer, creating a low-pressure zone that draws in oceanic air.
- Onset: Kerala, around June 1 (normal date); withdraws from Northwest India by mid-October
- Triggered by northward migration of the Inter-Tropical Convergence Zone (ITCZ)
- Delivers ~75% of India's total annual rainfall
- The "core monsoon zone" (central India, roughly 18°N–26°N, 73°E–82°E) is most critical for rain-fed agriculture
- Variability in onset date and rainfall distribution has major consequences for crop sowing calendars
Connection to this news: A below-normal monsoon means delayed onset, uneven distribution, and inadequate soil moisture — all of which directly affect kharif sowing and yield outcomes.
Kharif Cropping Season and Monsoon Dependence
Kharif crops are sown at the beginning of the monsoon (June–July) and harvested in September–October. They rely almost entirely on monsoon rainfall and are highly vulnerable to its variability. Unlike rabi crops (sown October–November; depend on residual soil moisture and irrigation), kharif crops have limited buffer against deficient rainfall.
- Major kharif crops: rice, maize, cotton, sugarcane, groundnut, soybean, arhar (tur), moong, urad, jowar, bajra
- Rice: single largest kharif crop; India is the world's largest rice exporter
- Pulses and oilseeds are critical for domestic food security and inflation control
- Rain-fed cultivation covers ~50% of India's 140 million hectares of cultivated area
Connection to this news: A 2026 below-normal monsoon increases the risk of kharif output shortfall, particularly for rain-fed pulses and oilseeds in states like Maharashtra, Rajasthan, Madhya Pradesh, and Karnataka.
El Niño's Impact on India: Historical Record and Statistical Significance
El Niño events in the Pacific Ocean suppress India's monsoon by disrupting the Walker Circulation and reducing moisture transport over South Asia. Historically, six out of ten El Niño years have been associated with depressed Indian monsoon rainfall. However, the relationship is probabilistic — not deterministic — and can be modulated by other factors including the Indian Ocean Dipole (IOD) and the Madden-Julian Oscillation (MJO).
- Six out of 10 El Niño years: below-normal or deficient monsoon in India (IMD historical record)
- Severe El Niño events (e.g., 1987, 2002, 2009, 2015) correlated with major Indian drought years
- The 1997–98 El Niño — among the strongest on record — saw India avoid major drought due to a counteracting positive IOD
- El Niño's suppressive effect is strongest in August–September (second half of monsoon season)
Connection to this news: IMD flags El Niño as likely to develop post-June 2026, raising the probability of rainfall deficiency in August–September — the most critical period for kharif crop water needs.
Food Security and Macroeconomic Implications of a Weak Monsoon
A below-normal monsoon has cascading economic effects beyond agriculture. Food prices rise as crop supply contracts, rural incomes fall with lower farm earnings, and government expenditure on food subsidies and procurement increases. The Reserve Bank of India (RBI) closely monitors monsoon forecasts because food inflation feeds into headline CPI, influencing monetary policy decisions.
- Agriculture contributes ~17% of India's GDP; ~45% of workforce engaged in agriculture
- National Food Security Act (2013) covers ~800 million beneficiaries — a major fiscal commitment that swells during drought years
- Minimum Support Price (MSP) operations for kharif crops are a key government response to poor monsoon years
- RBI's Monetary Policy Committee (MPC) considers food inflation trajectory in rate-setting decisions
- Drought-hit states may invoke the National Disaster Management Authority (NDMA) drought relief framework
Connection to this news: If the 2026 monsoon remains at or below 92% of LPA, the government may need to activate food procurement support, drought relief, and fiscal stimulus measures for vulnerable rural households.
