Air quality in the ‘very poor’ category across NCR
In addition to rising temperatures, Delhi-NCR air pollution levels remain a major concern, with several areas recording hazardous Air Quality Index (AQI) readings.
- Bawana (Delhi): 310 AQI
- Anand Vihar: 268 AQI
- Ashok Vihar: 281 AQI

AQI levels above 300 fall under the ‘very poor’ category, posing significant risks of respiratory illness, especially for children, elderly citizens and those with pre-existing conditions.
Health advisory for residents
With the combined Delhi heatwave and air pollution stress, health experts have advised residents to:

Authorities have warned that continued dry conditions and stagnant air could further worsen pollution levels in the coming days.
