Delhi/ the coldest Decembers: 1992 2018
See graphic, December temperatures in Delhi, 1992 2018 Amit.Bhattacharya |3.7°C: Chilliest Dec morning in 4 years, month in line to be coldest since 2005 | The Times of India
2018: Delhiites experienced a cold December after witnessing three consecutive years of mild weather during the month. The average minimum temperature till 23 Dec was around a degree lower than normal.
In fact, at 7.7 degrees C, the average minimum temperature till 23rd of this month was already the lowest in December since 2005 (see graphic).
Yadav said western disturbances (WDs) — episodic wind flows travelling into north India from southern Europe and west Asia, which bring rain and snow into the region — have not significantly impacted the northern plains so far this month, with most blowing over from J&K.
“While the hills have received some snowfall, the northern plains have been largely dry and cloudless. Moisture levels have thus been low and dense fog hasn’t formed in most parts of northwest India so far. This has led to a pattern of sunny days and cold nights, with persistent northwesterly winds adding to the chill,” Yadav said.
In fact, this is the first instance since 2011 when temperatures in the capital have fallen below 4 degrees C before December 25. Temperatures such as Sunday’s minimum of 3.7 degrees C are usually seen in the capital during the peak winter period — generally the last week of December and the first two weeks of January.
The last time Delhi had December temperatures lower than 3.7 degrees C was on December 28, 2014, when 2.6 degrees C was recorded at Safdarjung.
1993- 2018: Lowest average minimum temperatures
Lowest average minimum temperatures in Delhi in December, 1993 2018
For Delhiites, December is usually a milder prelude to the severe chill of January. But this season, peak winter didn’t just arrive early, it has broken temperature records.
The December of 2018 was the coldest in 13 years and the third-coldest in the past 50 years in the capital. The month had six days of below 4 degrees C temperatures, the highest for December since 1973. Minimum temperatures have, in fact, remained below normal for 18 consecutive days (since December 13) now.
The major reason for the sustained chill was the absence of fog. This was the clearest December in at least 22 years, with just 145 hours of fog (of all types) against a normal of 300 hours. The month had just two nights and a total of nine hours of dense fog while the normal is nine nights and 45 hours.
Just as unusually, the average minimum temperature of the month was 6.7 degrees C, lower than the average minimum of last January (7 degrees C). Thus, 2018 was a rare year when December was colder than January [of the same year, i.e. 11 months before].
Delhi/ mild Decembers, but not global warming: 2015-17
New Delhi: For the third time in a row, Delhiites ushered in the New Year without experiencing the severe chill so characteristic of peak winter in the capital. This was the third consecutive December in Delhi without the temperature falling below 5 degrees Celsius for a single day.
The month of December can sometimes be mild in Delhi. But to have three such Decembers back-to-back is much more unusual — this was just the second instance in the past 25 years. The average maximum temperature this December was almost one degree above the 25-year mean while the average minimum was higher by 0.7 degree C.
Is this part of a larger global warming trend? Met officials say it’s difficult to make that connection.
“We analysed temperature data for December since 1992 and found no significant trends. The average minimum temperatures seem to be rising but not enough for it to be climatologically significant,” said Kuldeep Srivastava, head of the Regional Weather Forecasting Centre.
Srivastava offered a more direct reason for the warmish trend this December — high altitude wind flows called western disturbances. WDs, as these are usually called, regulate winter weather in north India by bringing in cold and wet spells into the region from as far out as southern Europe.
“This year, only one WD impacted Delhi-NCR this month, when the city got rain on December 11, followed by a sharp drop in night temperature. Other WDs have been coming into the region, but all of them are so positioned that they have only been affected Jammu and Kashmir,” Srivastava said.
On an average, two to three WDs hit NCR in December, he added.
December this year has seen mostly clear skies, which has played a role in keeping day temperatures on the higher side. “Wind direction too has been mostly westerly, whereas it’s northerly winds that bring temperatures down during this time of the year,” the RWFC official said.
Average temperatures this month, however, weren’t as high as in the same month last year, which was the second warmest December on record in Delhi since 2000.

Minimum temperatures in Delhi in Dec. 2018.’
Dec 2005, 2018 experienced the most cold waves
India experienced 167 instances of cold waves, the highest in 13 years, across different stations in December, according to data from the India Meteorological Department (IMD). In 2017, December saw just 30 such instances.
A cold wave is a spell of cold weather in an area when the minimum temperature plunges below what is normal for that time of year by more than 5°C. In the past two decades, only 2005 had more reported instances of December cold waves at 177.
A K Srivastava, head of the climate research division at IMD, Pune, said, “This means if a station’s normal minimum temperature is 11°C, its actual night temperature was recorded at 6°C or lower — a departure of -5°C. In the previous years, the number of such instances in the month of December was significantly less,” he said.
This winter has been marked by frequent western disturbances, which provided precipitation in the form of rain and snow in parts of north India, he said.
This time, the cold northerly winds were affecting several regions for a longer duration too. “If these winds blow for a short duration, they reach as far as central India. However, if they blow for several days, say four to five days, they reach as far as Rayalaseema and Telangana,” said Palawat.

Delhi/ 2mm: first wet spell in December in 3 years/ 2017
Light rain hit Delhi and National Capital Region on Monday evening, bringing with it the prospect of relief from high pollution levels that were hovering close to “severe” till the morning and some winter chill over the next few days.
The Safdarjung weather station had recorded 2mm of rain till 8.30pm and more rain was forecast for later in the night and Tuesday morning. This was the first proper wet spell in the month of December in the capital for the past three years. The capital did not get any rain in December in 2015 and ’16, while almost trace rain (0.1mm) was recorded last week (December 7).
Delhi’s overall air quality index was 361on Monday, which falls in the “very poor” category. However, air quality is likely to improve to “poor” or “moderate” levels on Tuesday.
Data according to CPCB’s central control room on Monday showed average PM 2.5 levels at 246 micrograms per cubic metre at 7 pm, while the average PM 10 levels were recorded at 417 micrograms per cubic metre – both over four times the safe standard.
Delhi/ 7.8 mm rain, air gets better/ 2017
Rain makes city colder, but air now so much better
The city’s maximum temperature plummeted on Tuesday after a spell of evening and overnight showers. Till 8.30am, 7.8 mm of rain was recorded, resulting in a sharp drop in pollution levels as well. The overall Air Quality Index (AQI) which was hovering close to “severe” levels on Monday morning fell to the “poor” category with an AQI of 214 recorded on Tuesday.
Capital’s Safdarjung observatory — which is considered as the base for Delhi’s weather — recorded 7.8mm of rainfall till 8.30am on Tuesday, while other weather stations also received similar rainfall overnight. Palam, Lodhi road and Ridge all received 6.8mm of rainfall till 8.30 am, while Ayanagar recorded 4.8mm of rainfall in the same period.
“The overnight showers have also contributed to a drop in pollution levels. Delhi’s average PM10 levels were hovering close to 420 micrograms per cubic metre on Monday afternoon, which were recorded at 139 micrograms per cubic metre on Tuesday at 8pm. Similarly, average PM2.5 levels which were recorded at 246 micrograms per cubic metre on Monday fell to 113 micrograms per cubic metre on Tuesday. The corresponding safe values for both ultrafine particles is 100 and 60 micrograms per cubic metre respectively.
In the National Capital Region (NCR), Ghaziabad, Noida and Faridabad were all recorded in the “poor” category, while Gurgaon recorded “moderate” air quality with an AQI of 192. Delhi’s average PM 2.5 levels hovered around two times the safe standard and levels are forecast to dip even more, experts said.

Delhi recorded its coldest morning of the season at just 5.1degrees Celsius — three notches below normal for the season.
Delhi 4°C/ Sikar, Churu 0.5°C, north India chilly, 2018
Delhi recorded its coldest December morning in four years, with the minimum temperature plummeting to 4 degrees Celsius — four notches below normal — as a cold wave swept through the northern plains. Night temperatures have already fallen below 2 degrees C at several places in north Rajasthan and Punjab. The lowest temperature recorded in the plains on Thursday was 0.5 degree C at Sikar and Churu, both in Rajasthan. Many places in the region also reported ground frost.
Jammu & Kashmir/ 2018
A day before the 40-day-long period of harsh winter ‘Chillai Kalan’ (the bigger or greater chill) sets in, cold wave swept Kashmir today with further dropping.
Water bodies have already started freezing in the Valley so are the water tapes in the morning. Small fires are lit each morning around water taps to de-freeze them. The freezing of tapes leads to water shortages in the morning.
The power crisis in Kashmir has further worsened as the temperatures dropped. The power cuts in Kashmir valley are around 10-12 hours and besides this, there are unscheduled power cuts that further irk the residents.

Capital shivers, but Ggn coldest at 2.4°C The Times of India Air Quality Remains Very Poor
Delhi NCR continued to reel under a cold wave and Delhi recorded a minimum temperature of 4.7 degrees, three notches below normal, maximum temperature was recorded at 20.6 degrees, one degree below normal. Gurgaon was the coldest – shivering at a minimum of 2.4 degrees Celsius.
Slightly increased wind speed — from 2.5 kmph to 3.6 kmph
Gurgaon 1.4°C, Jammu 3.9, Delhi 4°C, 2018
Gurgaon recorded a low of 1.4 degrees Celsius. Delhi matched its own season’s low of 4 degrees. Air quality in the region has also deteriorated to ‘severe’ with Delhi recording an overall air quality index of 421 on Saturday.
Experts said the increase in moisture content, aided by low winds and falling temperature could see air quality stay in a similar range for the next few days due to these unfavourable weather conditions.
Jammu & Kashmir, 2018
WDs may hit J&K on Jan 1-2
Bhaderwah 0.1 degrees Celsius
Drass in Kargil district was the coldest place at minus 17.3 degree Celsius
Gulmarg minus 5.5 degrees Celsius
Jammu 6.7 degrees Celsius
Kargil minus 14.5 degrees Celsius
Leh recorded minus 14.3
Pahalgam minus 6.7 degrees Celsius
Srinagar minus 4.4 degrees Celsius
Bhaderwah 12.5 degrees Celsius
Jammu 19.7degrees Celsius
The sub-zero temperatures have led to the freezing of fringes of Dal lake and other water bodies in Kashmir. The water tapes have also frozen in Kashmir creating water shortages in the morning but as the sun comes out, the frozen tapes melt bringing relief to the people.
The power cuts in extreme cold weather conditions have added to the hardships of the common people.
Zaffar Ahmad said that consumers are facing 10-14 hours of power cut daily and that during the remaining hours power trips off after every half an hour. He said that the Power Department says that they have enough power as per the consumer load but they blamed consumers for power thefts. “We are paying bills as per meter reading. If any consumer is resorting to power theft, he should be booked under law”, he said.
Muzaffarnagar 0°C, Gurgaon 3.5, Delhi, 3.7°C, 2018
2018: Chilliest December morning since 2014 as the temperature dipped to 3.7 degrees Celsius on the fourth day of the cold wave sweeping across north India. The mercury touched freezing point (0 degree C) at Muzaffarnagar in western UP.
Gurgaon continued to be the coldest place in Delhi’s neighbourhood at 3.5 degrees C.
Kashmir, Gulmarg/ minus 12.5°C, 2015

Delhi/ Season’s worst fog hits 220 flights/ 2017
New Delhi: It was a nightmare for travellers flying in and out of Delhi on 31 Dec 2017 morning as almost 220 flights from IGI airport were affected by the season’s worst fog.
Visibility at the airport fell to as low as 50 metres on the morning of New Year’s eve, with flight schedules going haywire. Low visibility also affected train services in the morning, with over 90 delayed, cancelled and re-scheduled due to the dense fog.
Over 150 flights were delayed and nearly 50 were diverted . Furthermore, around 20 flights were cancelled due to low visibility on the runway.
15 trains cancelled, 57 delayed due to fog
According to Met officials, visibility fell below 200 metre by 6am which is classified as “dense” and it further intensified to “very dense” by 7am when the visibility fell below 50 metre in the airport area. Sources said that no flight could take off for nearly four hours between 7.30am and 11.00am— there should be a minimum runway visibility of 125 metre for flights to take off.
“Fog of very dense category severely affected the IGI airport in the morning, with both general airport visibility and runway visibility at all sides remaining below 75 metre. This is by far the worst fog of the season,” said an airport Met official.
IGI airport is CAT IIIB compliant because of which pilots qualified to land in visibility of 25-50 metre were able to land during this period. However, nearly 50 flights were diverted to nearby airports as many pilots were not CAT IIIB-compliant.
Airport sources said that even though visibility improved to 2,000 metre during the day and operations at the airport restored to normal, delays continued throughout the day.
Meanwhile, the dense fog also led to 57 trains arriving late in the morning and 18 more were re-scheduled. Railway officials said another 15 trains had to be cancelled due to poor visibility. Met officials forecast dense fog for Monday morning as well with maximum and minimum temperatures to be around 23 and 5 degrees Celsius, respectively. The minimum temperature on New Year’s eve was recorded at 6.4 degrees Celsius — one degree below normal.
