Delhi’s National Capital saw its lowest monthly minimum temperature—17 °C—on Sunday, a drop of 0.2 °C below the season’s average after a night of rain that cooled the city.
The maximum temperature, 31.1 °C, also fell 0.7 °C below the average, while 4.4 mm of rain fell, bringing the month’s cumulative total to 62.3 mm.
Air quality improved overnight, with the AQI falling to 153 in the moderate range; 11 of 54 monitoring stations logged poor air quality, the worst reading 245 at IIT Delhi.
The IMD forecast a return to moderate AQI on Monday but warned that from Monday to Wednesday the city could slip into the poor category, with readings above 200.
Earlier this month, Delhi had recorded a 16.9 °C minimum on 25 Oct 2025, and the ridge area consistently shows the lowest minima and highest maxima among stations.
Meteorologists will monitor the shifting weather as the Central Pollution Control Board prepares to issue advisories for commuters amid the expected deterioration.
