The air quality index (AQI) on Monday morning was 317, ANI reported. The minimum temperature was recorded at 7.6 degrees Celsius, two degrees below the season’s average.
The relative humidity was 85 per cent, while the meteorological department forecast that the sky will remain clear, PTI reported. The maximum temperature will hover around 27 degrees Celsius.
An AQI between zero and 50 is deemed to be good, 51 and 100 satisfactory, 101 and 200 moderate, 201 and 300 poor, 301 and 400 very poor, and 401 and 500 severe.
