Air quality in Karachi
Right now Karachi has a US AQI of 85 (Moderate), with PM2.5 around 24 µg/m³. Air quality is acceptable. Unusually sensitive people should consider limiting long or intense outdoor activity. The AQI is driven mainly by PM2.5 — fine particles from traffic, industry and burning that reach deep into the lungs. Values update hourly.
What PM2.5 does to your health
PM2.5 particles are small enough to pass from the lungs into the bloodstream. Short-term exposure can cause coughing, throat irritation, watery eyes and breathlessness; sustained exposure is linked to asthma, heart and lung disease. Children, older adults, pregnant women and people with existing heart or respiratory conditions are most at risk and should watch the AQI closely.
How to protect yourself on high-AQI days
When the AQI is high: stay indoors and keep windows closed during peak pollution, run an air purifier with a HEPA filter if you have one, avoid outdoor exercise (your breathing rate multiplies your exposure), and wear a well-fitting N95/KN95 mask outside — ordinary cloth or surgical masks do little against PM2.5. Rinse eyes and nose after being outdoors, and keep sensitive family members in the cleanest room.
Smog season in Pakistan
From November to January, many Punjab cities — Lahore, Faisalabad, Gujranwala and beyond — suffer severe smog. Cool, still winter air traps emissions near the ground (a temperature inversion), while crop-residue and waste burning add fine particles. This is when AQI readings most often reach “Unhealthy” or worse, so checking the daily figure matters most in these months.

PM2.5 are fine particles smaller than 2.5 microns — from vehicle exhaust, industry, brick kilns and crop or waste burning. They are small enough to reach deep into the lungs and bloodstream, which is why PM2.5 is the pollutant that most often drives the AQI and the main health concern.
Do I need a mask in Karachi today?
At AQI 85, most people don't need a mask outdoors. Sensitive individuals may still prefer an N95 on higher-pollution days.
Why does Karachi get so much smog in winter?
In late autumn and winter, cooler air and low wind trap pollution near the ground (a temperature inversion), while crop-residue and waste burning add to it. This seasonal smog is why AQI in Punjab cities often spikes from November to January.
