Delhi's air quality was on the brink of the 'severe' category on Sunday with an overall AQI reading of 382 - the worst recorded in the country for the day.
Fifteen monitoring stations of the city recorded air quality levels in the 'severe' zone, having AQI readings over 400, data showed.
The city also recorded its lowest nighttime temperature so far, as thick smog and haze shrouded it in a dense cover during the morning and evening hours.
The minimum temperature recorded on Sunday was 16.5 degrees Celsius, 1.2 degrees above normal, according to the weather department.
The national capital's 24-hour average Air Quality Index (AQI), recorded at 4 pm every day, stood at 382, worsening from 316 the previous day.
The locations where air pollution levels reached the 'severe' zone are Anand Vihar, Ashok Vihar, Bawana, Dwarka, Jahangirpuri, Mundka, NSIT Dwarka, Najafgarh, Nehru Nagar, Okhla Phase 2, Patparganj, Punjabi Bagh, Rohini, Wazirpur and Vivek Vihar.
Despite the temporary relief provided by the winds, Delhi saw a spike in pollution levels following Diwali, with a noticeable jump recorded on Sunday.
Elsewhere in the country, several places recorded AQI levels in the 'very poor' category, though still better than the national capital. Bahadurpura, in Telangana, recorded an AQI of 335, Uttar Pradesh's Muzaffarnagar 302, Noida 313 and Haryana's Sonipat 321.
An AQI between zero and 50 is considered 'good', 51 and 100 'satisfactory', 101 and 200 'moderate', 201 and 300 'poor', 301 and 400 'very poor', 401 and 450 'severe' and above 450 'severe plus'.
The maximum temperature was recorded at 33.2 degrees Celsius, 2.7 degrees above normal, according to the weather department.
The humidity level fluctuated between 64 and 95 per cent during the day.
The weather office forecast said shallow fog was likely on Monday morning, with maximum and minimum temperatures expected to settle at 34 and 17 degrees Celsius, respectively.

The Air Quality Index (AQI) around Akshardham was recorded at 230, in the 'Poor' category, in Delhi this morning as per the Central Pollution Control Board (CPCB).
Delhi's air quality remained in the 'poor' category for the fourth consecutive day on Friday as the city continued to reel under rising pollution levels in the run-up to Diwali.
As pollution levels rise across Indian cities, understanding what Air Quality Index (AQI) numbers mean is key to protecting your health.
Delhi's winter anti-pollution plan for 2025-26 is now active, with authorities stepping up measures across dust control, vehicles, construction, industry, waste, and stubble burning as the city braces for seasonal pollution.
Diwali celebrations lead to air pollution due to the burning of crackers and the climactic change. Read on as we discuss impact of high AQI on health and how to stay safe.

Friday December 20, 2024While some may argue that people in Delhi are now more aware of air pollution than they were a decade back, my rebuttal would be that awareness does not mean that people are concerned.

Friday November 08, 2024हमारी हवा जहरीली हो रही है. गुरुवार की शाम को जब मैं इस मुद्दे पर लिखने बैठी तो AQI लगातार 400 पार जाकर दम घोंट रहा था. बहुत लोगों को यह मामला बोरिंग लगे, लेकिन जब आप अपने साथ काम करने वालों को खांसते-हांफते देखते-सुनते हैं, तो चिंता होने लगती है. सुबह उठते ही दरवाजे खिड़कियां खोलने के लिए डॉक्टर मना कर रहे हैं. बड़े बुजुर्गों के लिए तो मॉर्निंग वॉक बाहर की दुनिया से सीधे संपर्क का ज़रिया है, लेकिन डॉक्टर इसकी भी मनाही कर रहे हैं.
