Mumbai receives an average of 523.1 mm of rain in the month of June but this year the city has received merely 87 mm of rain till date. Though Mumbai holds the capacity of recording 100 to 150 mm of rain just in a day but according to the latest weather update by Skymet Meteorology Division in India, the city will not be able to meet the on-going deficit. There is no significant Monsoon surge in the coming 5 days, which could bring heavy showers to mitigate the deficiency.
The west coast of peninsular India right from south Gujarat to Kerala will continue to receive Monsoon rain with good showers over Konkan, Goa and Karnataka. But the intensity of rain will remain less over north coastal Maharashtra including Ratnagiri and south coastal Gujarat for the next few days.
According to Skymet, Southwest Monsoon has been making a slow advancement after making a sluggish start this year possible due to the tropical cyclone ‘Nanauk’, which had been controlling the free flow of westerly winds favourable for the Monsoon surge. Skymet is hoping for rain to gradually pick up over Kerala but deficiency might not be mitigated considering that 2014 is an El Nino year. El Nino in India has already made a huge impact on date of onset and may also affect the overall monsoon performance, increasing or decreasing rainfall in a region.
| Year | Rainfall |
| 2014 (El Nino) | 87 mm so far |
| 2013 | 984 mm |
| 2012 (Evolving El Nino) | 311 mm |
| 2011 | 664 mm |
| 2010 | 600 mm |
| 2009 (El Nino) | 220 mm |
Skymet has already explained the impact of El Nino on Monsoon in Mumbai. The monthly average was seen to be really low in El Nino years of 2009 and 2012, as compared to normal monsoon years of 2010, 2011 and 2013, when rainfall in a day was more than 100 mm on several occasions.
