November Brings Cooler Temperatures and Rising Pollution in Delhi-NCR; GRAP Measures Expected
From November 1, Delhi-NCR will experience dropping minimum temperatures around 17-18°C and maximums near 30-31°C, marking the early winter phase. Cold, dry air will worsen pollution levels, keeping the Air Quality Index in the poor to very poor range. The Commission for Air Quality Management is likely to enforce the next phase of the Graded Response Action Plan with stricter pollution control measures soon.
Delhi and the National Capital Region (NCR) are entering a colder phase with the onset of November, as minimum temperatures are predicted to fall from 18°C to about 17°C or lower, while maximum temperatures will hover around 30 to 31 degrees Celsius. The India Meteorological Department forecasts clear skies with no rainfall from October 30 to November 4, but with light fog and mist during early mornings and evenings. This temperature decline signals early winter but also exacerbates air pollution because cold, dry air traps pollutants close to the ground, causing rapid air quality deterioration. The Air Quality Index is expected to remain in the poor to very poor category without rain to cleanse pollutants. In response, the Commission for Air Quality Management and related agencies are likely to initiate the next phase of the Graded Response Action Plan (GRAP), which may include banning construction and demolition activities, restricting truck movements, intensifying road cleaning, and regular water sprinkling to control dust. Humidity will fluctuate between 60% and 85%, increasing fog and smog risks, especially during mornings and evenings. Health officials advise limiting outdoor exposure, especially for vulnerable groups, and using masks when outside. The colder weather and pollution issues align with trends across North India, indicating the gradual onset of winter with associated health and environmental challenges.
