 Weather (general)
 2013-18, 2019/ Air quality, temperatures
Cloudy skies and intermittent rain may have dampened the festive spirit but there’s still reason for cheer.
Rain and cloudy conditions helped keep October heat at bay. The city recorded its lowest maximum temperature for the month at 26.7 degrees Celsius on 19th, compared to the last two years. Last year, the lowest maximum for the month was 33, on the same date, while the lowest was 30.6 degrees on 12th, in 2017. Weathermen said high maximum temperature is recorded in the second half of the month, after withdrawal of the south-west monsoon, which in the past was in the first half. The highest maximum for the month had touched 38.6 degrees on 17th in 2015.
K S Hosalikar, deputy director-general (western region), IMD, said various reasons kept October heat at bay for Mumbaikars, the first being delayed withdrawal. Even though the normal date is September 30, this year it was October 14. Therefore, during the first fortnight of October, withdrawal of monsoon conditions, like rain with thunder showers, prevailed. Only during one week this month, few days prior to monsoon withdrawal and thereafter from October 12-19, maximum temperatures were on the higher side, hovering around 35-36 degrees.
“With formation of Cyclone Kyarr in Arabian sea and rain, along with cloudy conditions, temperatures here once again dropped, with a sharp dip, from 36 on October 19 to 26.7 on October 21. The sun was out only on October 27, and the expected rise in temperature in the second fortnight was really not felt, considering that in the past years most days of October have a maximum temperature in the range of 35 degrees. This season, the maximum rose to 36.6 only for a day,” he said. The city recorded a maximum of 36.6 degrees on October 15.
 2017: highest rainfall since 1902

The incessant rainfall over the past two months has made 2017 the wettest year for Bengaluru city.
The annual rainfall for the city, 1,615.2mm as on Saturday morning, is the highest ever.
A meteorological department official said the city is facing a unique weather system wherein the south-west monsoon

BENGALURU: The incessant rainfall over the past two months has made 2017 the wettest year for Bengaluru city. The annual rainfall for the city, 1615.2mm as on Saturday morning, is the highest ever, more than 1606.8 mm, the earlier record, in 2005. The Indian Meteorological Department has rainfall data for 115 years.
L Ramesh Babu, an IMD director, Bengaluru city, said Friday night showers helped set the new record and with more than two and a half months left in the year, the annual rainfall could be much higher.
A senior official at the meteorological department said Bengaluru city is facing a unique weather system wherein the south-west monsoon has extended its stint and soon the north-east monsoon will arrive. "The combination of the weather system coupled by low pressure situation created in the Arabian Sea is resulting in showers over interior Karnataka and Bengaluru falls in this region," he added. The officer said there has been record rainfall in Bengaluru city after 1990.
"One has to analyse the possible relation to climate change as extreme weather events are related to it. Bengaluru is a growing city and has been experiencing heat island effect which further results in rainfall after a prolonged harsh summer or dry run," he added. The Friday night rain wreaked havoc in west Bengaluru families.
 2017: highest rainfall since 1916
• Hyderabad received 248.3 mm of rainfall in the first 15 days of October. • • This is the highest rainfall during October in the last 100 years. • • In October 1916, Hyderabad received 355.1 mm of rainfall, which is an all-time record.
HYDERABAD: Hyderabadis may have heaved a sigh of relief from the incessant rains that lasted almost a fortnight from October 1, but the quantum of rainfall the city had received is a record in 100 years. The number of rainy days during October is also a meteorological record with some or other part of the city receiving rainfall for almost 15 days. Hyderabad received 248.3 mm of rainfall in the first 15 days of October. This is the highest rainfall during October in the last 100 years. In October 1916, Hyderabad received 355.1 mm of rainfall, which is an all-time record. Though the rainfall received thus far this October falls short of the all-time record, it is the first time in a century - i.e. after 1916 - that the city received such a high quantum of rainfall.
This is the second time in two decades that Hyderabad got over 200 mm rainfall during October. The other time rain crossed the 200 mark was in October 2013 when city received 239.1mm rain. The current depression in Bay of Bengal failed to bring in rainfall in Hyderabad or Telangana, though the IMD had forecast moderate to heavy rainfall in Telugustates. Had the rainfall trend that began on October 1 continued beyond October 15, Hyderabad would have beat the October 1916 record. IMD, Hyderabad data reveals the city received 248.3 mm of rain since October 1 as against the normal of 64.9 mm.
This is 283% excess in the season, beginning October 1.
If the rain since January 1, 2017 is seen,the city got124%excess. As against normalof 82cm,Hyderabad so far received 102cm.
Data since November 1891 shows Hyderabad received the heaviest rain of 431 mm in 36 hours during September 27-28, 1908. There are records of the city receiving up to 499 mm of rain in a month. Butthis pertains to September when the southwest monsoon is at its peak. This time southwest monsoon did not withdraw on time and persisted beyond October second week. The other time the city got 241.5 mm rain in 24 hours was on August 24, 2000.

 Delhi: unanticipated hail, 35.2mm of rain, 2019
Thursday began with pleasant blue skies, gentle breeze and a mellow autumn sun. No one saw the black mass of clouds coming. These gathered almost secretly as the sun set and let loose their fury on an unsuspecting Delhi just after 7pm, with a thunderstorm accompanied by hail and torrential rain that rattled windowpanes and lashed the streets, sending Delhiites scurrying for cover.
Trees uprooted, roads waterlogged
With heavy rain lashing the capital on Thursday evening, traffic was affected in various areas due to waterlogged roads. There were 10 incidents reported of trees falling and electric poles getting uprooted.
Till late at night, traffic was heavily affected on Mehrauli-Badarpur Road due to waterlogging and uprooting of an electric pole near Neb Sarai. Major snarls were also reported near Ashram, RTR flyover and IIT
One of the season's heaviest showers in many parts of Delhi came three days after the monsoon season officially ended on September 30. It prompted many to post videos and pictures on social media, wondering if this was the revenge of nature. Till as late as 4pm, the weathermen had forecast only light rain in the capital although a thunderstorm warning had been issued a day earlier.
Within a space of an hour and a half, 35.2mm of rain had lashed the Safdarjung weather station, leading to operations at IGI Airport being shut for around 25 minutes and throwing the city‘s traffic out of gear.
Met officials said there was high moisture over the region, which usually comes into north India during the monsoons through easterly flows from Bay of Bengal. Adding to this, rising heat during the day and disturbed air patterns in the neighbourhood came together to construct the storm.
“A strong cyclonic circulation was present over Haryana while a trough line — an eastwest line of low air pressure conducive to rain activity — was passing through Haryana and crossing close to Delhi before cutting through Uttar Pradesh. Day time heat also created a low pressure area in the region, leading to moisture being drawn in. The merger of these conditions led to the sudden change in weather,” said Kuldeep Srivastava, head of IMD’s regional weather forecasting in Delhi.
Delhi’s Safdarjung station received 35.2mm of rainfall between 5:30 pm and 8:30 pm according to IMD readings.
The rain began around 7pm, with a majority of the 35.2mm recorded at Safdarjung falling within an hour. Commuters said the rain was falling in sheets at central Delhi. “Even with the car’s wipers set at full speed, visibility remained very poor,” said a journalist driving through the area during the downpour.
The rain and strong winds hit air operations at Delhi’s IGI Airport. “Runway operations were suspended between 7.56pm and 8.20pm due to heavy rains. Four flights were diverted and several delayed, which led to a cascading effect of flight delays until midnight,” said an airport official.
Srivastava said such thunderstorms generally occur during the monsoon’s withdrawal phase. “While the monsoon is yet to start retreating, conditions for the withdrawal are slowing setting in with a change in wind direction to northwesterly and a sudden rise in temperature. Moisture content during this time is generally high in the surrounding areas and can be sucked in. Another low pressure area was created in southwest Delhi, alongside Haryana and this merged to give good rainfall over Delhi,” he said.
Delhi’s Palam observatory had recorded 20.4mm of rainfall till 8.30 pm. Delhi’s maximum temperature on Thursday was 34.8 degrees Celsius, one notch above normal, while the minimum was 23.8 degrees.
The initial forecast for Thursday at IMD’s regional weather website was “thundery development”, which was revised in the afternoon to “light” rain and further revised to “moderate” by the evening. Clearly, the extent of Thursday’s weather disturbance had not been foreseen.

 NCR, Light rain/ 2018
The Times of India
Light rain in parts of the National Capital Region on Thursday, aided with an increase in wind speed, helped improve air quality as Delhi’s overall Air Quality Index (AQI) came down to 210 from a reading of 241.
“Rain eluded Delhi, however, it was recorded in other parts of NCR, which has provided a cooling effect,” said BP Yadav, director, Met department.

2018 Nip in the air as temperature falls to 17.5°C
The weather in Delhi turned nippy on Friday morning after rain in nearby areas, with the minimum temperature falling to 17.5 degrees C, three notches below normal. This was the lowest temperature recorded in the first half of October at Safdarjung in at least the past eight years. Night temperatures usually fall in the latter half of the month. Higher wind speeds also reduced pollution.
According to met officials, the change in temperature has been due to winds blowing from the north and northwest after strong rain in parts of the northern plains. “Snowfall has also been recorded in the mountains and this has led to cold winds blowing towards this side of northern India,” said a met official. The maximum temperature on Friday was recorded at 32.4 degrees C — one degree below normal.
