Delhi, long known for its harsh winter smog, has recorded its second-best air quality for January since 2022, offering a rare moment of relief for its residents. The Centre for Research on Energy and Clean Air (CREA) reported that the city’s average Air Quality Index (AQI) this month was 307, slightly higher than January 2025’s 306, which remains the cleanest January in recent years. While this represents an improvement compared with earlier winters, air quality continues to pose significant health risks.
Throughout the month, Delhi experienced a mix of air conditions. There were a few days when the air was moderate and relatively safe for outdoor activities, but for much of January, the city remained enveloped in poor to very poor air, affecting both sensitive groups and the general population. On a couple of days, pollution reached severe levels, a category considered dangerous even for healthy adults. Experts point out that winter weather conditions, such as low wind speeds and cooler temperatures, trap pollutants close to the ground, making it difficult for the city to shake off its smog. CREA also noted that the final day of January was expected to see very poor air quality again, underlining that the battle against pollution is far from over.
For Delhiites, the news is both encouraging and cautionary. The city’s air is slightly cleaner than in previous years, but residents are still advised to monitor AQI levels, wear masks on polluted days, and limit outdoor exposure, especially children, the elderly, and those with respiratory conditions. The report highlights that while small improvements offer hope, sustained action through stricter pollution control measures, greener transport options, and lifestyle changes will be crucial if Delhi is to enjoy truly breathable winters. For now, the city can take some comfort in knowing that the skies are marginally clearer, even if only for a short while.
