Delhi AQI Live — Air Quality, PM2.5 Alerts, and Forecast

Delhi is one of the world's most complex urban air-quality environments, shaped by transport emissions, industry, construction dust, and regional sources. Pollution can persist across large areas rather than isolated streets, especially during calm periods. Even short outdoor exposure on poor-air days may represent a meaningful health burden for vulnerable groups.

Late autumn and winter typically produce the most severe episodes. Temperature inversions, weak wind, and reduced mixing trap emissions near the surface, while regional biomass burning and secondary particle formation can intensify PM2.5 dramatically. Visibility often declines during these periods, and daily AQI can remain in unhealthy ranges for extended stretches.

Managing exposure in Delhi requires active monitoring and flexible scheduling. Cleaner windows sometimes appear after rain, frontal passages, or stronger winds, but they may be brief. Families often use live AQI and hourly forecasts to adjust school travel, outdoor exercise, and ventilation timing while prioritizing protection for children and older adults.
