8. 1931: 318.9 mm

9. 1916: 318.8 mm

10. 1955: 317.2 mm

For the period 1901-2022, August rainfall in the country is decreasing at the rate of 0.7mm/decade.

This year, throughout the month, break monsoon conditions prevailed for nearly 24 days. 

It is the month of September that holds the key to making or breaking the year. Although this month has a modest average of 167.9mm rainfall, it is considered the most volatile to change fortunes.

September assumes  importance. If the month receives its normal rainfall or even a modest shortfall of about 10%, the season can avert the drought scare.

Any deficiency, in excess of 15% rainfall will push it closer to yet another El Nino-driven ‘drought’.
