India is entering the final month of the southwest monsoon with the India Meteorological Department expecting September 2026 rainfall across the country to be below normal.

What the IMD is saying

The IMD’s September 2026 monthly outlook, dated August 31, says rainfall over India as a whole is most likely to be below normal. It also says subdued rainfall activity is likely to continue over peninsular India during the first week of September.

Why September rainfall matters

September rainfall can affect standing crops, reservoir inflows, water planning and local flood or drought risks. A weaker finish to the monsoon can increase pressure on irrigation and drinking-water planning in areas that have already received less rain.

What people should watch

• State and district-level IMD warnings rather than only the national average.
• Reservoir and water-supply conditions in rainfall-deficient regions.
• Crop and agriculture advisories.
• Short-range heavy-rain alerts, because a below-normal month can still contain intense local rainfall.

Bottom line: A below-normal national forecast does not mean every part of India will be dry. Local rainfall can vary sharply between states and districts.
