 "The southwest monsoon ended with 8 per cent surplus rains, the best performance in the last four years (since 2020).")
The southwest monsoon made its onset over Kerala on Saturday, marking the earliest arrival over the Indian mainland since 2009, the India Meteorological Department (IMD) announced.
“Normally, the southwest monsoon hits Kerala by June 1 and covers the entire country by July 8,” the IMD said. The withdrawal typically begins around September 17 and is completed by October 15.
In recent years, the monsoon arrived in Kerala on May 30 (2024), June 8 (2023), May 29 (2022), June 3 (2021), June 1 (2020), June 8 (2019), and May 29 (2018), according to IMD data.

“There is no direct relationship between the onset date and the total rainfall over the country during the season,” an IMD official told news agency PTI. “The timing of the monsoon’s arrival in Kerala does not necessarily reflect how it will progress across other regions. It is influenced by a mix of global, regional, and local climatic factors.”
In its April forecast, the IMD predicted above-normal rainfall for the 2025 season, while ruling out the impact of El Nino conditions — typically associated with deficient rainfall over the Indian subcontinent.
