Delhi battles poor air quality as temperature dips to 19°C

Delhi's air quality continued to worsen as autumn progressed, with the Air Quality Early Warning System indicating that poor air quality conditions are expected to persist through October 25. The situation reflects the seasonal pattern that typically affects the national capital during the transition from summer to winter months.

The minimum temperature in Delhi was recorded at 19°C, marking a cooler trend as the season advances. Meteorological officials attribute the combination of lower temperatures and stagnant atmospheric conditions to the deterioration in air quality across the region.

The Air Quality Early Warning System, which monitors pollution levels across Delhi, has flagged the extended forecast of poor air quality as a matter of concern for residents and health authorities. Poor air quality ratings indicate that air pollution levels are above the acceptable threshold, potentially affecting vulnerable populations including children, the elderly, and those with respiratory conditions.

Authorities have urged residents to take necessary precautions, including limiting outdoor activities and using air purification measures indoors. The poor air quality is expected to be a defining feature of the coming weeks as Delhi enters its winter season, a period historically marked by challenging air quality conditions.
