Key to timely monsoon
A hot summer, experts say, is a key factor to a timely monsoon. However, the impact of a warming ocean and its impact on the monsoon is likely to be better apparent around April when the IMD issues its first forecast for the monsoon.
The southwest monsoon in 2019 (June to September) delivered 10 per cent above average rainfall in the country, the highest in 25 years. In 1994, the rainfall was 110 per cent during the June-September period. Before that, more than 10 per cent above average rainfall was witnessed in 1990 (119 per cent).
