While Mumbai saw wettest July ever, the city has recorded second lowest rainfall recorded in the month in a decade. With this, Mumbai witnesses driest August since 2015.
According to the monthly rainfall figures from the India Meteorological Department (IMD), 176.8 millimetres of showers were recorded this August, which is only around 31 per cent of the monthly average rainfall quota of 566.4 mm.
Till August 18, Mumbai recorded 30.6 mm of rainfall, while above 140 mm of rainfall was recorded in the last fortnight of the month. The city recorded 68% deficit in August rain.
In 2015, 154 mm was recorded in the month — the lowest in the past decade.
If reports are to be believed, the driest August in Mumbai was recorded in 1972 when the IMD observatory recorded 108.6 mm of rain and the wettest August was recorded in 1958, when the city received 1,254 mm of rainfall in the month.
Moreover, IMD officials said that the there is no possibility of good rainfall till September 10 over Mumbai and Konkan belt.
Officials attributed the primary reason of below average rainfall to the monsoon trough that is settled at the foothill of Himalayas. Additionally, there was no proper low pressure that developed in August, the monsoon current in Arabian Sea was also significantly weaker during the month and the trough got settled in the foothills of the Himalayas. These resulted in below average rainfall in Mumbai.”
In July, Mumbai recorded 1,769 mm rainfall, which was almost double the average quantum of rain for that month. In June also, Mumbai recorded 549 mm of rainfall that surpassed the monthly quota of 537 mm. The city also surpassed the seasonal average of rain by the end of July despite a delay in monsoon onset.
Meanwhile, water stock in all the seven lakes that supply water to Mumbai stand at 90.59%, while the level last year on August 31 was 97% and in 2021 it was around 89%.
