India faces monsoon deficit: August rainfall below normal

India is grappling with a deepening monsoon crisis, as rainfall deficits reach concerning levels across the country. As of mid-August 2026, the monsoon deficit has been reported to be as high as 40% in certain regions, with satellite images indicating a stalled monsoon over large parts of India. This widespread lack of rainfall is raising significant concerns for the crucial kharif sowing season, soil moisture, and overall water availability. The India Meteorological Department (IMD) has issued forecasts predicting below-normal rainfall for August and the remainder of the southwest monsoon season (August-September). This projection is largely attributed to the strengthening El Niño phenomenon in the Pacific Ocean, which typically suppresses monsoon activity over India. The IMD's initial long-range forecast in April had already indicated a below-normal monsoon, predicting 92% of the Long Period Average (LPA), which was later revised to 90% of the LPA, anticipating El Niño conditions. The current rainfall trend is broadly consistent with these earlier outlooks. While July saw some recovery with rainfall being 1% above the LPA nationally due to strong activity over Central India, this improvement was not uniform. As of August 2, 2026, the cumulative seasonal rainfall remained 12% below the LPA, with a significant number of districts (47%) experiencing deficient or large-deficient rainfall. Sixteen subdivisions have recorded rainfall deficiencies ranging from 20% to 38% below normal, with notable shortfalls in states like Bihar (-38%), Arunachal Pradesh (-36%), Assam & Meghalaya (-35%), and Coastal Andhra Pradesh & Yanam (-35%). The strengthening El Niño conditions are a major factor suppressing monsoon circulation across the country, leading to prolonged dry spells, localized meteorological drought, lower soil moisture, and moisture stress on rain-fed crops and water reservoir levels. This situation is directly impacting agriculture, with kharif crop sowing lagging behind last year's pace. Early monsoon deficits have cut India's kharif acreage and reservoir levels, threatening supplies of key commodities like rice, pulses, grains, cotton, and oilseeds. Live storage in major reservoirs is significantly below last year's levels, constraining water availability for crop growth and increasing downside risks for yields. This precarious situation is prompting importers to reassess India's export potential for the 2026/27 marketing year, particularly for rice, sugar, cotton, and select pulses, potentially impacting global commodity prices. Despite the overall deficit, the monsoon season is also characterized by a paradox of extreme weather events. Some states are experiencing intense downpours, flash floods, and cloudbursts even as the national rainfall deficit persists. Experts emphasize the need to look beyond seasonal rainfall totals and focus on the timing, intensity, and geographical distribution of rainfall. While forecasting has improved, translating these warnings into timely, impact-based decisions for disaster preparedness and agricultural planning remains a challenge. The article also touches upon the role of climate change, noting that global warming, warming oceans, and changing atmospheric circulation are increasingly interacting with traditional climate drivers like El Niño, making monsoon forecasts more complex. Scientists emphasize that the challenge is no longer just predicting the total rainfall, but forecasting its location, timing, and intensity in a warming climate. The monsoon crisis also highlights the environmental context, with discussions on deforestation potentially impacting rainfall patterns. India's monsoon deficit is a critical issue with far-reaching implications for its economy, food security, and the livelihoods of millions.
