The first winter rain overnight significantly improved Karachi’s air quality, providing residents relief from previously unhealthy pollution levels.
Measurements recorded across the metropolis showed mostly healthy air quality, with several neighborhoods shifting into green categories, reflecting immediate atmospheric cleansing caused by sustained rainfall and cooler seasonal winds.

Data was collected through the live project operating in Karachi under the World Air Quality Index network, which provides real-time PM2.5 readings from multiple monitoring stations.
Visual maps released on Tuesday evening highlighted sharp improvements in districts previously reporting unhealthy conditions, including central and eastern areas, where pollution levels dropped within hours after rainfall.
Neighborhoods such as Garden, Aram Bagh, and Clifton Block areas recorded good to moderate AQI values, while Shahrah-e-Faisal and University Road showed noticeable reductions compared to previous days.
Specialists caution that the improvement may be short-lived, as forecasts indicate rising pollution levels in coming days if dry weather, traffic congestion, and construction activities resume.

How many categories are there to measure Air Quality?
AQI 0–50: Good
The air quality is considered excellent, with minimal or no risk to public health. There are no necessary precautions for the general population.
AQI 51–100: Moderate
Air quality is generally acceptable; however, there may be a slight health concern for a small number of individuals who are unusually sensitive to air pollution. Active children, adults, and people with respiratory conditions like asthma should consider limiting prolonged outdoor activity.
AQI 101–150: Unhealthy for Sensitive Groups
Sensitive individuals, such as those with asthma or other respiratory issues, may begin to experience health effects, although the general population is unlikely to be affected. It is advised that active children, adults, and those with respiratory conditions limit extended outdoor exertion.
