2021: 3rd hottest Aug in 120 years, freak rain days
Sep 11, 2021: The Times of India
August 2021, which saw a huge rainfall deficit, was the third hottest August in the country in the past 120 years and was also marked by the Ridge area in the capital breaking its 24 hour rainfall record for the month.
As far as temperature was concerned, the monthly average maximum, average minimum and mean temperature over all India for the month of August during 1901-2021 shows the average ‘maximum temperature’ over all India was third highest (31.7 degree C) and average ‘minimum temperature’ was eighth highest (24.4 degree C) while the ‘mean temperature’ over all India was third highest (28.1 degree C) since 1901, making it the third hottest August.
“The observed average maximum, average minimum and mean temperature for the country as a whole during August 2021 are 31.7 degree C, 24.4 degree C and 28.1 degree C respectively, against the normal of 31.1 degree C, 24 degree C and 27.5 degree C based on period 1981-2010,” said the India Meteorological Department’s (IMD) analysis for August.
The overall rainfall deficit (24% below long period average) had led it to be the lowest August rainfall in the country in the last12 years (after 2009). The IMD said certain stations recorded ‘very heavy’ to ‘extremely heavy’ rainfall with six of them including Delhi Ridge, Car Nicobar, Aizwal, Bundi, Thanjavur and Shivpuri reporting their 24-hour respective record rainfall in August.

Delhi/ Safdarjung, 2014: 39.1 degrees Celsius, five notches above normal, the highest for the month of August since 1991. Because of the absence of rain for more than two weeks. The rise in temperatures wass a result of a combination of factors, officials said. Delhi had been witnessing unusually clear skies and the winds had been westerly. "As opposed to moisture-laden easterly winds from Bay of Bengal that are common during the monsoon season, the westerlies are dry. Pollution levels are not too high as well, so the sunlight reaching the city is bright and hot. This is the prime reason for high temperatures," said a Met official.
Delhi, Palam, 2014: 40.7 degrees Celsius, the highest since 1988.

28 Aug 2018 Gurugram got 128 mm of rainfall in less than six hours — the highest in the last eight years, said Deputy Commissioner Vinay Pratap Singh.
Office-goers faced nightmarish commute as underpasses and roads remain waterlogged for several hours
Light rain began around 2 a.m. and turned into a downpour between 5 a.m. and 8 a.m. The Gurugram-Delhi Expressway was the worst hit with traffic moving at a snail’s pace till late in the afternoon. Hero Honda Chowk, the perennial flooding point on the expressway, was again inundated. The newly-constructed underpass at the chowk was completely submerged.
In a rerun of the monster jam witnessed in Gurugram in 2016. More than three hours after the rains stopped around 8 a.m., all major intersections of the city: Rajiv Chowk, IFFCO Chowk, Netaji Subhash Chowk, Signature Towers, Atul Kataria Chowk and Hero Honda Chowk, were waterlogged leading to long traffic snarls.Motorists travelling from Jharsa Chowk to HUDA City Centre through Signature Towers had a tough time as they remained stuck for around an hour. Similarly, the stretch extending from HUDA City Centre metro station to Netaji Subhash Chowk on Sohna Road also witnessed major congestion. Besides the internal roads in Sector 15 Part-II, stretches in Sectors 14, 23, 24, 46, 29, 44, 45, 46 and DLF areas were also flooded.

Mumbai, 151.8mm rainfall/ 2017
Worst rains since 2005 bring Mumbai to halt |DECCAN CHRONICLE|Aug 30, 2017
The maximum city came to a complete standstill on Tuesday 29 Aug 2017 when an unabating downpour lashed Mumbai, inundating roads, causing traffic snarls and stranding commuters. Though there were no casualties — unlike in the case of the 2005 deluge — the impact on the city residents’ life was no less.
The showers threw regular life out of gear, with several parts of the city getting flooded; road and railway services being hit badly; water entering houses and hospitals; and hapless people being stranded across the city. According to the India meteorological department, the Santa Cruz weather station recorded 88.4 mm of rainfall in the suburbs in the last 24 hours.
The Colaba weather station recorded 151.8mm of rainfall during the same time period. As per the Brihanmumbai Municipal Corporation’s automatic weather stations, from 8 am to 6 pm, the city area received 173.4mm of rainfall, whereas the eastern and western suburbs witnessed 193.85 mm and 192.77 mm of rainfall respectively.
Weather officials believe this is the heaviest and longest bout of rain since July 26, 2005 when the city was ravaged by floods.
As the rain’s fury kept increasing on Tuesday, it had huge impact on city life as several low-lying areas like Sion, Chunabhatti, Pratiksha Nagar, Hindmata, Chembur, Dadar TT, Matunga, Maheshwari Udyan, Parel, Mahim Subway, Prabhadevi, Bandra, Kurla, Vidyavihar, Powai, Santa Cruz, Juhu, Malad went underwater quickly. At many places, the water rose up to waist-level.
“It looked like 26 July had revisited the city. There was water everywhere in Central Mumbai. The entire Sion-Parel belt had gone underwater, making residents jittery. The rising water levels added to their fear. In Parsee Colony and Matunga, water had entered in several houses,” said civic activist Nikhil Desai from King’s Circle.
All major roads such as the Western Express Highway, Eastern Express Highway, Jogeshwari-Vikhroli Link Road, Santa Cruz-Kurla Link Road, Babasaheb Ambedkar Road and Lal Bhahadur Shastri Road witnessed huge traffic jams. At several places, vehicular traffic was diverted due to water-logging. South-bound traffic towards Matunga was diverted to Wadala due to water-logging on the Eastern Express Highway at Amar Mahal Junction, S.G. Barve Road and V.N. Purav Road in Chembur.
The BMC authorities asked people to stay indoors, but it was too late for most, who had to wade through dirty brown waters to offices. At some places, vehicles could barely be seen above the waterline. There were also the only-too-familiar sights of thick branches nestling on shattered windshields or dented car tops.
On Tuesday afternoon, traffic was closed on the Bandra-Worli Sealink due to heavy water-logging at its Worli end. Poor visibility and high velocity winds further made the sealink unsafe as motorists complained of cars getting buffeted around by the wind.
As the water-logging was cleared, police finally allowed vehicular movement on the sealink.
