Overview

  • Delhi's Air Quality Index (AQI) has remained in the 'severe' category for four consecutive days, with an average AQI of 429 on Friday, marking the worst December air quality since 2021.
  • Low wind speeds and increased moisture have trapped pollutants in Delhi, with PM2.5 levels posing significant health risks to vulnerable populations, including children and the elderly.
  • Authorities in Delhi have implemented Stage IV of the Graded Response Action Plan (GRAP), banning construction activities and restricting non-essential polluting trucks from entering the city.
  • Mumbai's AQI has declined to 'moderate' levels, nearing the 'poor' category, with smog reducing visibility and raising concerns about the city's air quality and public health.
  • Weather forecasts for both cities predict temporary relief from worsening pollution next week, with potential rainfall in Delhi and stable conditions in Mumbai.
