Delhi’s air-quality forecasting system can predict severe pollution episodes with reasonable accuracy, but gaps in emissions data and limited detail on pollution flowing in from neighbouring districts constrain its forecasts.

While Delhi's air quality improved slightly in 2025 compared to 2018, pollution levels remain well above safe national standards.

Delhi has logged its worst air quality for the start of October in six years, recording an average Air Quality Index (AQI) of 174 over the first four days.

The concentrations of PM2.5 and PM10, two of the pollutants most closely associated with harmful air pollution, slightly increased this September compared with last year.

Despite the Delhi government and MCD deploying over 1,800 monitoring teams to tackle dust, trash burning, and industrial smoke, air pollution control remains weak.

Delhi's carbon monoxide levels have shown a steady rise this year, with monthly averages reaching their highest in years until May.

From winter to summer, Delhi’s air has shown a slow but steady rise in carbon monoxide levels this year till May.

In January in Delhi, air pollution was very bad not just because of fine dust but also due to high levels of nitrogen dioxide (NO₂) and other toxic gases. A study of official air quality data found that NO₂ stayed above safe limits for over 25 days at most monitoring stations, and benzene, a cancer-linked gas, was above the World Health Organization’s recommended level on many days.

At 4pm, 38 of Delhi’s 39 active stations were “severe,” with only Shadipur in “very poor.” Wazirpur topped 500 – the upper limit of CPCB’s monitoring; Rohini and Ashok Vihar also breached it, while Jahangirpuri, and Mundka hit 499

A news report claims that officials in India's capital city, Delhi, have been interfering with air quality monitors.

A major investigation has revealed a critical failure in Delhi's air pollution monitoring system. Two-thirds of the national capital does not have access to reliable, real-time air quality data.

Delhi has 38 air quality monitors, but their placement leaves out 65% of the national capital without reliable air quality estimates.

The national capital Delhi woke up to a cold and foggy Monday morning, with the minimum temperature recorded at 10 degrees Celsius.

According to the monthly data, the last time Delhi logged a cooler November was in 2020, when the average minimum was 10.3°C.
