An AQI of zero to fifty is deemed ‘excellent,’ 51 to one hundred ‘acceptable,’ 101 to 200 ‘moderate, 201 to 300 ‘poor,’ 301 to 400 ‘extremely poor,’ and 401 to 500 ‘severe.’
For the past week, Delhi has had frigid days due to dense upper-level fog that made it difficult for sunlight to reach the surface. In the early hours, there was still a thin layer of fog. In the second half of the day, it was predicted to clear out.
The minimum temperature was expected to be 10 degrees Celsius, which was roughly 2-3 degrees below average, and the maximum temperature was expected to be 18 degrees Celsius. On Wednesday, Delhi saw a low of 7.4 degrees Celsius and a high of 18.1 degrees Celsius, both of which were below normal.
