On Saturday morning, a heavy fog engulfed Delhi and its neighbouring areas including Noida and this is something out of place in late March. The national capital has been enjoying an unusual mixture of low-than-normal temperatures, better quality of air and sporadic rains and nothing that should be perceived during this season.
The foggy weather follows a day after Delhi has registered the lowest March day in six years, which is yet another indicator of the sudden change in weather. Pictures taken in other parts of the city had less visibility with people walking out in the early morning with big crowds observed at the historic Jama Masjid where Eid-ul-Fitr prayers are still observed amidst thick fog.
There have also been improvements in the quality of air. At 8 am, the Air Quality Index (AQI) was at 94 and it was in the category of satisfactory. This is quite a change where Friday registered an AQI of 93 as the last time the air quality in Delhi was in this range was about 5 months ago. The most recent of these happened on October 9, 2025, when the AQI had reached 99.
This abnormal weather has been explained by the experts as a result of the recent western disturbances which have caused rain, cloud cover and the cool winds in North India. Such conditions have not only reduced the temperature but also aided in the dispersal of pollutants resulting in clean air.
Though the residents have appreciated the good quality of air, the meteorologists warn that these trends are only temporary and temperatures are most likely to increase once the region is fully in the summer season.
