Monsoon 2026: The Driest Monsoon in 11 Years for India, Half Of The Districts In The Country Rain Deficient

India Meteorological Department data reveals India recorded its driest monsoon season in 11 years between June and September, ending with a 12.6% overall rainfall deficit driven by a powerful El Niño. Of the 730 districts in the country, 310 have recorded severe rainfall deficiency.

The seasonal shortfall pushes 2026 into official drought territory, marking the nation's first nationwide monsoon deficit since 2015 and placing this year among the ten weakest monsoons since Independence. A late-season deep depression across northern and central states in late September trimmed the deficit from 15% down to 12.6%, but the delayed spell arrived too late to rescue damaged standing crops across major agricultural belts.

Nearly Half of All Indian Districts Face Drought Conditions

Out of roughly 730 districts monitored by meteorologists nationwide, between 43% and 48% ended the season in rainfall deficit categories. Over 310 districts recorded rainfall deficits ranging between 20% and 59%, while nearly 40 districts suffered extreme deficits exceeding 60%.

The widespread dry spell places severe pressure on groundwater reserves and winter crop sowing across key grain-producing states, including Uttar Pradesh, Punjab, Bihar, Karnataka, and Andhra Pradesh. Government departments are now evaluating crop damage and reservoir levels to prepare emergency relief measures for affected farming communities.

East and South Suffer Historical Shortfalls

Regional data exposes severe spatial disparities across the country, with Eastern and Southern states bearing the heaviest burden:

• East and North-East: States including Bihar, Jharkhand, Gangetic West Bengal, and Assam recorded their lowest monsoon rainfall totals since 1901. Bihar suffered its fifth consecutive monsoon drought, with 31 out of 38 districts failing to reach normal rainfall levels.

• South Peninsula: Southern states registered a 23% rainfall deficit, the region's worst performance since 2002. Rayalaseema in Andhra Pradesh proved hardest hit, ending the season 38% below normal.

• Punjab: Shifting from 41 % excess rainfall last season to a 42% deficit this year, Punjab logged its worst monsoon performance since 2004.

• West Rajasthan: The desert state suffered a rare drought, falling 31% short of normal seasonal rain.

• Odisha: Standing out as the primary exception, Odisha recorded its wettest monsoon season in 20 years due to recurring low-pressure tracks passing directly over the state.

Pacific Warming Suppresses Bay of Bengal Rain Systems

Atmospheric scientists point to the equatorial Pacific Ocean, where an unusually strong El Niño event developed early in the year. The warming surface waters disrupted global atmospheric circulation, weakening the southwest monsoon winds right from their June arrival.

Monsoon depression systems that typically form over the Bay of Bengal and carry moisture into interior farming regions failed to develop through June and July. The absence of these rain-bearing systems left millions of hectares of agricultural land parched during the initial sowing period. While isolated weather disturbances brought heavy localized downpours late in September, large swathes of the country remained starved of regular precipitation.
