Overview
- Delhi’s overall AQI stood around 341 at 7 am on Wednesday in the 'very poor' band, with several hotspots previously touching 'severe' levels, CPCB data show.
- The CAQM revoked Stage-4 GRAP curbs on January 20 after a marginal average improvement, keeping Stages 1–3 in force and easing truck entry and some construction for linear projects.
- Forecasts point to isolated to scattered rain and gusty winds over January 22–24 across Delhi-NCR, with air quality likely to remain 'very poor' until then.
- Mumbai’s air has oscillated sharply this week, with official readings showing 'satisfactory' to 'moderate' conditions on some days and third-party monitors reporting spikes to 'unhealthy' 224 and 'severe' 303 with locality peaks near 398.
- Judicial scrutiny is intensifying in Mumbai as the Bombay High Court, which called 'moderate' AQI unacceptable, set a January 23 hearing while the BMC cites hundreds of show-cause and stop-work notices at construction sites.
