India's monsoon delivered an unexpected turnaround in July, with rainfall ending the month within the normal range despite forecasts of below-average precipitation and a strengthening El Niño.

Releasing its latest monthly and seasonal outlook on Friday, the India Meteorological Department said the average rainfall over India during August 2026 is most likely to remain below 94% of the long period average. The normal rainfall for August, based on the 1971-2020 climatology, is 254.9 mm, according to reports.

LPA refers to the rainfall recorded over a particular region in a given period, such as a month or a season, averaged over a long period, typically 30 to 50 years.

While the national rainfall figure appeared reassuring, its distribution remained uneven. Central India received 29% excess rainfall, while east and northeast India recorded a 30% deficit and south India remained 28% below normal. Since June 1, the cumulative monsoon rainfall deficit has stood at 14%.

According to a Climate Trends briefing, a series of weather systems during July sharply reduced the national rainfall deficit from 40% at the end of June, easing concerns over a significant monsoon shortfall.
