NEW DELHI | July 22, 2026 – India’s Southwest Monsoon 2026 has entered a make-or-break phase. After a volatile start marked by a 40% rainfall deficit in June followed by a temporary July revival, meteorologists at the India Meteorological Department (IMD) have issued crucial warnings: the next few days could determine the fate of the entire 2026 rainy season.
With El Niño conditions officially established in the equatorial Pacific Ocean and strengthening rapidly, unusual upper-atmospheric Jet Stream movements and unfavorable Madden-Julian Oscillation (MJO) phases are creating unprecedented uncertainty for India’s agricultural heartland.
3 Key Factors Making the Next Few Days Critical for Monsoon 2026
1. El Niño Strengthening in the Pacific
The India Meteorological Department (IMD) and NOAA have confirmed that sea surface temperatures in the Central Pacific have breached critical warming thresholds. El Niño suppresses moisture-laden monsoon winds, leading to extended dry spells during peak agricultural months.
2. High-Altitude Jet Stream Disruption
Upper-level winds flowing 8 to 15 kilometres above the Earth’s surface – known as the Subtropical Jet Stream are shifting unpredictably. These atmospheric currents directly control where low-pressure systems deposit heavy rainfall across northern and central states.
3. Monsoon Break & Unfavorable MJO Phase
The monsoon trough has shifted northwards toward the Himalayan foothills, triggering a classic “monsoon break.” Combined with an unfavorable phase of the Madden-Julian Oscillation (MJO) moving across the Indian Ocean, the formation of rain-bearing Bay of Bengal low-pressure systems has temporarily slowed down.
“The next 7 to 10 days are pivotal. If mid-level atmospheric circulations do not revive over the Bay of Bengal soon, rainfall deficits in major grain-producing states could widen significantly.”

Rainfall Deficit & Impact Overview
| Region | Status | Risk Level | Primary Impact |
| Northwest India | Below Normal | Moderate | Paddy & Sugarcane Sowing |
| Central India | Fluctuating | High | Soybean & Cotton Crops |
| East & Northeast | Severe Deficit | Critical | Groundwater & Reservoir Levels |
| Peninsular India | Near Normal | Low | Sowing Pace Maintained |
High Stakes for Agriculture & Economy
The monsoon is crucial for India’s agrarian economy, driving over 50% of the net cultivated area and replenishing major reservoirs across the country.
- Crop Sowing Delays: Delayed or deficient rainfall in late July directly impacts the sowing cycle for Kharif crops such as rice, pulses, and oilseeds.
- Inflation Concerns: A prolonged monsoon lull threatens crop yields, which can lead to rising food prices and inflationary pressures.
- Water Security: Hydropower generation and urban drinking water supplies heavily depend on sustained rain during the July–August window.
