17 Oct
Summary
- 45% of India drenched in extreme rainfall, triggering devastating floods and landslides
- 2025 monsoon saw 108% of the long-period average rainfall, a trend of wetter monsoons
- Experts attribute intensifying monsoons to climate change, not El Niño or La Niña
As of October 17th, 2025, the Southwest Monsoon of the year has left an indelible mark on India, with 45% of the country drenched in extreme rainfall. This has triggered devastating floods, landslides, and claimed over 1,500 lives across the nation.
The monsoon season, which spanned from June to September, saw unprecedented rainfall, with the season concluding at 108% of the long-period average (LPA). Experts have pointed to climate change as the primary driver behind this intensifying deluge, rather than the traditional factors of El Niño or La Niña.
This year's monsoon marks the second consecutive season with above-normal rainfall, underscoring the growing influence of global warming on India's weather patterns. The number of rainy days has decreased, but the quantum of rainfall per event has increased significantly, according to the former Director General of the India Meteorological Department.
The impact of the 2025 monsoon has been felt across the country, with 19 of 36 meteorological subdivisions (46% of India's landmass) recording normal rainfall, 12 subdivisions (35%) experiencing excess rainfall, and two subdivisions (10%) seeing large excess rainfall. Only three subdivisions, covering 9% of the country, faced deficient rainfall.
