  • The surplus rain was primarily in Rajasthan, Gujarat, Maharashtra, Karnataka, Kerala, Telangana, Chhattisgarh and Odisha.
  • Though August rainfall was in excess, the figure for this year’s monsoon as a whole were likely to be within the department’s June forecast of a normal (96 to 104% of the long period average) rainfall.
  • In the normal course, the monsoon begins its retreat from September 15 and this can go on for nearly a month.
