Air Quality Deteriorates to ‘Very Poor’ in Delhi and North India
Delhi’s air quality deteriorated to the “very poor” category on Monday morning, November 2, 2026, according to official reports. Several other cities in north India, including Noida, Kaithal and Hapur, also recorded very poor air quality, raising concerns about pollution levels across the region.
According to air quality data, Delhi’s Air Quality Index (AQI) stood at 310 at 8 a.m. on Monday. An AQI between 301 and 400 falls under the “very poor” category, indicating unhealthy air conditions that can affect people’s health, particularly those with breathing problems.
Government forecasts suggest that Delhi’s air quality may remain in the “poor” to “very poor” range for the next five to six days. The situation has worsened over the past few days. On Sunday evening, the AQI was recorded at 261, which falls under the “poor” category. This was a significant increase from Saturday’s AQI of 117, which was classified as “moderate.”
Air pollution in Delhi and other parts of north India usually increases during the winter months. Cooler temperatures and slower winds make it difficult for pollutants to spread and disperse. As a result, harmful particles and gases remain in the air for longer periods, leading to higher pollution levels.
Several factors contribute to the seasonal rise in pollution. Stubble burning in agricultural fields during October and November is one of the major concerns. Farmers burn leftover crop residue after harvesting, releasing smoke and pollutants into the atmosphere.
Fireworks used during festivals can also add to pollution levels. Vehicle emissions, construction activities and road dust further increase the amount of pollutants in the air. These sources combine with unfavourable weather conditions to create serious air quality problems during winter.
The rising pollution levels have once again highlighted the need for effective measures to control air pollution in Delhi and neighbouring cities. Authorities continue to monitor air quality and issue forecasts to help residents understand changing pollution conditions.
With pollution expected to remain high in the coming days, residents are advised to follow official air quality updates and take appropriate precautions, especially children, older adults and people with respiratory or heart-related conditions.
