In a significant development, it has come to light that Mumbai has registered a shortfall of over 30 per cent from its average rainfall in the month of August.
While the city clocks an average of 566 mm in the month, Mumbai only received 379 mm of the average quantum in August, this year.
The India Meteorological Department (IMD) has forecast light to moderate showers, with some thunderstorm activity, in Mumbai and Thane till Thursday, September 5. This indicates that the ongoing dry spell is here to stay for now.
Despite the shortfall in August, Mumbai fared much better rainfall than last year. In 2023, the Santacruz station recorded only 177.2 mm rainfall in the entire month of August, making it the city’s driest August in at least a decade.
Despite being the city’s second wettest month, Mumbai reeled under a dry spell throughout most of August this year.
Mumbai surpassed its seasonal average quota of rainfall on August 24. This is attributed to the heavy rains in July when the city recorded a surplus of nearly 50 per cent.
While the city receives a seasonal average rainfall of 2,319 mm spanning the four monsoon months, the Santacruz observatory has recorded 2432 mm rain so far.
However, of this total quantum, Mumbai’s Santacruz station recorded only 379 mm rain in August this year, failing to surpass its monthly average rain quota of 566 mm. With this, Mumbai has clocked a shortfall of nearly 33 per cent from the monthly average.
Furthermore, the month also ended on a dry note as data furnished by the IMD showed that between Saturday, August 31, and Sunday morning, September 1, the Santacruz station registered 0.6 mm rainfall while the Colaba observatory recorded 1 mm rain.
On the other hand, the department has sounded a yellow alert in Raigad until Thursday, September 5, stating the likelihood of heavy rainfall in isolated pockets.
Besides, the total stock in the seven lakes supplying water to Mumbai touched 96.84 per cent on Sunday morning.
