Central and East India fared extremely well in terms of Monsoon rain in the last 10 days but the west coast where Monsoon rain is usually very heavy during the Monsoon season, remained deficit.
The west coast plays a vital role in affecting the overall rainfall figures of the country. As rain along the west coast during the month of June remained poor, it directly affected the national cumulative rainfall figure, which stood at a deficit of 43%. Mumbai received an abysmal rain of 88 mm against the monthly average of 523 mm. Other weather stations like Kochi and Mangalore also faced the similar fate, adding to the overall deficit.
July is supposed to be the peaking month of Monsoon in terms of rain, with monthly average rainfall for Mumbai being 800 mm, Mangalore 1104 mm, Goa 900 mm, Kozhikode 817 mm and Kochi 593 mm.
Let us now analyse how the west coast performed since the 16th of July by dividing the region in 3 divisions. The table below shows the rainfall deficiencies in these 3 regions.
| Date | Kerala | Coastal Karnataka | Konkan & Goa |
| 16th July | 24% | 30% | 31% |
| 21st July | 23% | 26% | 26% |
| 25th July | 19% | 24% | 22% |
We can infer from the figures above that Kerala fared well in last 4 days when the deficit came down by 4%.
By the 17th of July, Mumbai had already received 997 mm of rain and covered the monthly average but Kochi and Mangalore had just received 467 mm and 265 mm of rain, respectively. In the last 10 days, Kochi received 167 mm and Mangalore 265 mm of rain.
Consequently, Kochi needs 120 mm of more rain to cover the monthly average, while Mangalore needs 300 mm. By the end of the month, these cities could cover up the deficit but the roll over from the previous month could keep the overall deficits in the range of 20 to 25%.
