Delhi and the National Capital Region (NCR) are currently experiencing a combination of 'severe' to 'hazardous' air quality and unseasonably warm daytime temperatures for mid-winter. On January 20, 2026, the Air Quality Index (AQI) in New Delhi was recorded as 'Hazardous' at 622 to 652 in various areas, significantly exceeding the 'severe' threshold. Neighbouring NCR cities like Ghaziabad and Noida have also reported alarming AQI levels, some crossing into 'Hazardous' territory. The maximum temperature forecast for Delhi on January 20 is expected to range between 23-25 degrees Celsius, with some predictions reaching up to 25.8 degrees Celsius. This is notably above the normal maximum temperature of around 19.6 degrees Celsius for this time of year. Minimum temperatures are hovering between 7 and 9 degrees Celsius. Due to the persistent and critical air pollution levels, Stage IV of the Graded Response Action Plan (GRAP) has been reimposed across Delhi NCR, bringing stricter pollution control measures. Dense fog continues to be a feature in the early morning hours, reducing visibility. The India Meteorological Department (IMD) forecasts that a fresh western disturbance is likely to bring very light rain or drizzle and stronger winds on January 23. These weather changes could offer temporary relief from the prevailing haze and improve air quality and visibility. However, the overall air quality is anticipated to remain in the 'very poor' to 'poor' category for several days.
