Monsoon Ends With 8% Surplus as IMD Flags Wetter October and Delayed Retreat

An unusually high number of low‑pressure systems fueled heavy spells that soaked the northwest and left the east and northeast short.

Overview

  • India received 937.2 mm of rain in June–September, about 8% above the long‑period average and the fifth‑highest seasonal total since 2001, according to the IMD.
  • Withdrawal that began over northwest India has stalled due to active systems near the Gulf of Kutch and in the Bay of Bengal, with the IMD projecting about 15% above‑normal rainfall nationally in October.
  • South Peninsular India is forecast to see above‑normal October–December rainfall (greater than 112% of the seasonal average), even as parts of northwest India are likely to be normal to below normal.
  • Rainfall disparities were stark: northwest India was about 27% above normal, central 15% above and the south peninsula 10% above, while the east and northeast received about 80% of normal, the second lowest since 1901.
  • The season featured roughly 18 low‑pressure systems over about 69 system‑days and severe impacts, with the IMD citing reports of 1,528 deaths tied mainly to floods and lightning; local updates include Delhi logging October’s average in a single day and Maharashtra expecting above‑normal October rain.
