India is bracing for a challenging September, with the India Meteorological Department (IMD) predicting below-normal rainfall across the country. This grim forecast comes on the heels of an exceptionally hot August, which recorded the highest average temperatures for the month since national records began in 1901.
El Niño's Intensifying Grip on Monsoon
The primary driver behind the anticipated weak monsoon is the strengthening El Niño phenomenon over the equatorial Pacific Ocean. Characterized by unusually warm sea-surface temperatures, El Niño significantly influences global atmospheric circulation and rainfall patterns, often leading to weaker monsoon rainfall in India.
The IMD's assessment indicates that El Niño conditions have intensified and are expected to strengthen further in the coming months, directly contributing to the rainfall deficiency witnessed during August and the projected shortfall for September.
August 2026 saw India's rainfall around 16 percent below its long-period average. For September, the IMD forecasts all-India rainfall to be less than 91 percent of the long-period average, which typically stands at 167.9 mm for the month.
Dual Threat: Heat and Drought
Compounding the rainfall deficit, August 2026 was officially India's hottest August in over a century. The IMD expects this trend of elevated temperatures to continue into September, with both average maximum and minimum temperatures likely to remain above normal across large parts of the country.
This combination of reduced rainfall and higher temperatures poses a significant threat, increasing heat stress, water demand, and pressure on various sectors, particularly agriculture.
Agricultural Sector Faces Renewed Concerns
The September rainfall outlook is critically important for India's agricultural sector. Several key Kharif crops, including soybean, cotton, maize, and pulses, are currently in vital growth and development stages. A prolonged rainfall deficit could severely impact crop yields, threatening food security and farmers' livelihoods.
Furthermore, inadequate soil moisture conditions could create significant difficulties for the sowing of upcoming winter crops such as wheat, chickpea, and rapeseed. India's economy is heavily dependent on the monsoon, which replenishes reservoirs, groundwater, and soil moisture, supporting a vast agricultural economy and millions of farmers.
