Where the monsoon has not arrived

A normal monsoon at the national level can still mean drought in nineteen states.

The IMD reports rainfall as a departure from the long-period normal for each subdivision, updated through the season. The all-India figure is an average of very different local realities, and the average is what gets reported.

Read subdivision by subdivision, the 2026 season shows a familiar split: deficit across large parts of the interior peninsula and the east, surplus and flooding elsewhere, in the same weeks.

What we measure

These are the indicators this topic is built from. Each names its source and the year that source refers to, because an official figure is not the same thing as a current one.

How we handle gaps

Where a source has not reported for a recent year, the gap is shown as a gap. We do not interpolate to make a series look continuous or a map look complete. Where two agencies publish different figures for the same thing, both appear and we say which is which.
