This year, Southwest Monsoon was on time but saw a long break in between which caused its arrival over several parts of the country to be late by about 10 to 15 days. However, Southwest Monsoon once again picked up pace and advanced over the entire country 15 days before its usual time.
The West Coast and Northeast India are the rainiest pocket and can sway the Monsoon averages either towards the deficient side or in surplus amounts across the country.

Any deficiency of 10 to 15% in these pockets by the virtue of their massive normals is not large for the region but Pan India becomes the sufferer and rainfall figures across the country get affected.
In the month of June, East and Northeast India were rain deficient by 20%, each. However, the rest of the three regions including North-West, Central and South were good performers. Northwest India saw a 12% surplus in terms of rains, Central witnessed -1% and South India observed rainfall surplus to the tune of 20%.
As of now, the deficiency over East and Northeast India has mounted to 32%, Northwest India is rain deficient by 7%. Central India during this time has recovered and gone to + 18%. Plenty of weightage is given to the central parts as they consist of two of the largest states including Maharashtra and Madhya Pradesh.
South India on the other hand, has been doing quite well in terms of Monsoon rains. Usually, South India during the Southwest Monsoon season does not see enough rain. South India also includes the least rainy areas including Rayalaseema and Tamil Nadu.
Therefore, good rains even on a couple of days shifts the rain amount to positive.
The southern Peninsula has not recorded heavy rains, but rainfall activity has been on and off resulting in 13% surplus rains. In fact, except Rayalaseema all the pockets observed above normal rainfall.
Due to the deficiency persisting over East and Northeast India, the entire country has been seeing rainfall deficit figures. However, if we remove East and Northeast India, then during both June and July the rainfall amount combined over Central, South and Northwest India is surplus by 10%. Rains have been quite good over these areas.
Talking about East India, East Uttar Pradesh, Bihar and Jharkhand have been seeing rainfall deficiency which happens to be a question of concern as they are largely dependent on Monsoon rains. Meanwhile, West Uttar Pradesh, Punjab and Haryana do not see a lot of Monsoon rainfall.
In the coming days, Bihar, Jharkhand and West Bengal may see some rainfall during the rest of July but the deficiency is not expected to slip too much.
