The retreat of the southwest monsoon from Rajasthan has accelerated significantly over recent days. Having traversed the western districts of the desert state, the withdrawal line currently extends across a corridor running from Barmer to Kotputli. In practical geographical terms, monsoon systems have already departed from more than half of Rajasthan. Weather forecasters project that the remaining cloud bands will completely clear the state border within approximately a week. This seasonal outcome presents a stark contrast to the previous year, when Rajasthan shattered a 108-year positive precipitation benchmark. In 2026, the state has instead logged a 17-year low in seasonal performance, leaving both agrarian communities and government authorities confronting mounting difficulties.
Deficit Reaches 21 Percent as Reservoir Inflows Shrink
According to weather department timelines, the formal withdrawal of monsoon moisture from Rajasthan typically concludes around the close of September. The current withdrawal schedule is expected to wrap up between September 25 and September 30. Cumulative precipitation figures reveal the extent of the seasonal shortfall. By the night of September 21, total rainfall recorded across Rajasthan reached only 335.5 millimetres. Under normal climatic conditions for this specific period, the benchmark figure stands at 425.4 millimetres.
This discrepancy leaves Rajasthan with an overall rainfall deficit of 21 percent compared to long-term averages. Multiple regions across the state failed to receive even their standard baseline allocations during the peak wet months. The sharp reduction in precipitation has translated directly into diminished storage levels across regional dams and water bodies. Several major reservoirs have received minimal inflows, creating imminent pressure points for upcoming seasonal drinking water supplies and local rural water distribution networks.
Weakest Seasonal Performance Since 2009
Data recorded through late September indicates that the current season is shaping up to be Rajasthan's weakest monsoon in roughly 17 years. The last comparable dry spell occurred in 2009, when the state registered a severe 43 percent shortfall below its seasonal norm. Throughout most intervening years following 2009, monsoon systems delivered comparatively stable and healthy precipitation across agricultural belts.
While lingering atmospheric currents may produce brief spells of light rainfall across isolated pockets of Kota and Bharatpur divisions in the coming days, meteorological assessments suggest these minor showers will not materially alter cumulative deficits. The seasonal total will conclude firmly in deficient territory as the primary monsoon trough recedes entirely from northwest India.
Agricultural Yields at Risk Amid Shifting Weather Cycles
The erratic progression of seasonal weather has heightened operational challenges for local growers. This year's abrupt drought has drawn heightened scrutiny because it arrives immediately after 2025, when torrential downpours caused Rajasthan to break a century-old positive mark that had stood for 108 years. Shifting from record-breaking precipitation to a 21 percent shortfall within a single annual cycle underscores extreme variations in precipitation consistency.
Agricultural production projections indicate that widespread moisture shortages during critical maturation phases are likely to significantly impact overall crop yields. As the withdrawal line prepares to exit the territorial bounds of Rajasthan over the next week, all regular monsoon precipitation will grind to a halt. The marked deficit leaves farming households facing significant economic uncertainty and constrained soil moisture reserves as they look ahead to the next agricultural cycle.
