According to data released by the Telangana Development Planning Society (TGDPS), the State’s rainfall was also substantially lower than the last year. Telangana received 988.3 mm during the 2025 Southwest Monsoon, making the 2026 rainfall 38% lower than the previous year.

The poor performance in this monsoon unfolded against the backdrop of an evolving El Nino — which is a periodic warming of the tropical Pacific Ocean that alters global atmospheric circulation and can weaken the conditions that bring moisture-laden winds to India, increasing the likelihood of deficient monsoon rainfall. The India Meteorological Department (IMD), in its forecasts issued ahead of the monsoon, had said that El Nino conditions were likely to develop during the Southwest Monsoon.

For Telangana, the rainfall shortfall was spread across all four months of the season. While 115.3 mm was received in June against the normal 130.3 mm, a deficit of 12%, 224 mm was recorded in July against 227.4 mm, a marginal deficit of 1%. The sharpest fall came in August, when the State received just 134.5 mm against the normal 215.8 mm, leaving a 38% deficit. September ended with 141.7 mm against the normal 167.1 mm, a deficit of 15%.
