Editorial Summary
Down to Earth reports that the Southwest Monsoon reached Kerala on June 4, 2026 — three days behind schedule and nine days behind IMD’s updated forecast. The IMD simultaneously downgraded the seasonal rainfall projection to 90% of the Long Period Average (LPA), classifying 2026 as a below-normal monsoon year. The arrival coincides with a rapidly developing El Niño event that climate scientists warn could rival the catastrophic 1876–78 El Niño — which triggered devastating famines across South Asia — raising urgent concerns about kharif crop production, reservoir storage, and water security across India.
The 2026 Monsoon — Key Parameters
| Parameter | Value |
|---|---|
| Monsoon arrival (Kerala) | June 4, 2026 |
| Normal arrival date | June 1 |
| Delay | 3 days |
| IMD forecast (June–Sept) | 90% of LPA |
| LPA (1971–2020) | 87 cm |
| Classification | Below normal (90–95% = below normal) |
| El Niño status | Developing; moderate–strong trajectory |
El Niño 2026 — Scientific Assessment
El Niño is a periodic warming of the central and eastern equatorial Pacific that disrupts the Walker Circulation — the east-west atmospheric loop that drives monsoon moisture delivery over India. When the Pacific warms, the Walker Circulation weakens, reducing the convection that pulls moisture-laden air from the Arabian Sea and Bay of Bengal toward the Indian subcontinent.
Why Scientists Are Alarmed About 2026
Down to Earth cites analysis from climate scientists at IITM Pune and NOAA that the 2026 El Niño has two characteristics that elevate risk:
- Rapid intensification: Pacific sea-surface temperatures are rising faster in 2026 than in any El Niño year since 1997–98 (which caused a severe pan-Asian drought)
- Superposition with Indian Ocean Dipole (IOD): A negative IOD — which also suppresses Indian monsoon — may develop concurrently, compounding the El Niño effect
The 1876–78 comparison: The Great Famine of 1876–78, triggered by one of history’s strongest El Niño events, killed an estimated 5–10 million people in India (then British India). While India’s food distribution, storage, and early warning systems are incomparably better today, a strong El Niño combined with governance failures could still cause serious humanitarian stress.
State-Wise Vulnerability
| Region | Expected Monsoon | Risk Level |
|---|---|---|
| Northwest India (UP, Rajasthan, Punjab, Haryana, Delhi) | 80–85% of normal | Very High |
| Central India (MP, Maharashtra, Chhattisgarh) | 88–93% of normal | High |
| Southern India (Karnataka, Tamil Nadu, Andhra) | 92–97% of normal | Moderate |
| Eastern India (West Bengal, Odisha, Bihar) | 95–100% | Low |
| Northeast India | 98–105% | Low (may be above normal) |
Agriculture at Risk: The Kharif Stakes
India’s kharif 2026 production depends heavily on the June–August rainfall window. Key crops at risk:
| Crop | Production (2025-26 baseline) | Risk from 10% Deficit |
|---|---|---|
| Rice | ~120 MT | Medium (irrigated areas partially insulated) |
| Pulses (arhar, urad, moong) | ~24 MT | Very High (largely rainfed) |
| Soybean | ~14 MT | Very High (rainfed, Central India) |
| Coarse cereals (maize, jowar, bajra) | ~48 MT | High |
| Cotton | ~35 million bales | High |
| Oilseeds | ~28 MT | High |
Inflation risk: Pulses and vegetables are most price-volatile during monsoon failures — a 15–20% crop shortfall in pulses could drive retail pulse prices up 30–50% by October–November.
Water Reservoir Status
India’s 150 major reservoirs (CWC monitoring) were at 42% capacity as of June 1, 2026 — near normal for this time of year. A below-normal monsoon would mean:
- Reservoirs ending the season at 75–80% capacity (vs. 90%+ in a normal year)
- Reduced availability for the rabi season (October–March) especially for wheat in the Indo-Gangetic Plain
- Lower hydropower generation — adding to India’s energy stress
Policy Response Options
Down to Earth recommends:
- Pre-position contingency grain stocks — FCI should increase buffer over and above the mandated minimum
- Activate NDMA drought protocols — early warning systems and relief codification for 100+ vulnerable districts
- Accelerate drip/micro-irrigation — budget ₹10,000+ crore from PMKSY for irrigation efficiency in pulses and oilseeds belts
- Price stabilisation fund — activate for pulses and vegetables; pre-commit to imports if domestic production falls short
- Drinking water security — identify 200+ drought-vulnerable districts for AMRUT/JJBY drinking water backup plans
