Lahore Smog Pushes AQI Past 530, Worst of the Season

Thick Lahore smog pushed the city’s air quality index past 530 on November 2, the worst reading of the season, putting Lahore at the top of the global list of the most polluted cities as hazardous air spread across Punjab.

Several neighbourhoods recorded far higher levels. Iqbal Town reached 836, Samanabad 828 and Gulberg 822, while Barki Road, Model Town, Cantt and Defence also crossed 600. A day earlier, the provincial government’s data showed Lahore at 478 at 7am, with Gujranwala at 500, the highest in the province that morning.

Lahore Smog: Area-Wise AQI Readings

Lahore Tops Global Pollution Ranking

On November 1, the global air quality ranking of major cities placed Lahore first with an AQI of 420, far ahead of other polluted cities in the region.

The same morning, several Lahore monitoring stations, including Barki Road, Shahdara, Multan Road, Punjab University, GT Road, Gulberg III, Wagah Border and Egerton Road, recorded readings of 500.

Other Cities Also Choking

Faisalabad’s average AQI was above 400, with Kotwali Road at 681. Multan recorded 260 and Sialkot above 200, while Peshawar stood at 255 and Islamabad at 173. On November 1, Sheikhupura recorded 336, Nankana Sahib 326, Dera Ghazi Khan 317 and Hafizabad 312. Residents in Multan have complained that brick kilns are still operating.

Why the Air Gets Worse in November

Early-morning conditions in Lahore have been almost still, with very light winds, high humidity and low sunlight. These conditions trap smoke and dust close to the ground, so pollution from vehicles, industry, brick kilns and crop burning builds up instead of dispersing. Any AQI reading above 300 is considered hazardous for the whole population.

The burning of crop residue after the rice harvest in Punjab, on both sides of the border, also adds large amounts of smoke to the air every October and November, which is why the Lahore smog season usually peaks at this time of year.

What the AQI Numbers Mean

• 0 to 50: good air.
• 51 to 100: moderate.
• 101 to 150: unhealthy for sensitive groups.
• 151 to 200: unhealthy for everyone.
• 201 to 300: very unhealthy.
• Above 300: hazardous, with health warnings for the entire population.

At 7am on November 1, Lahore’s temperature was 19°C with 84 per cent humidity and wind of just 0.3 metres per second, conditions that keep pollutants close to the ground. Earlier, in October, the Punjab government banned smoke-emitting vehicles from roads as part of its anti-smog measures.

How Lahore Smog Affects Your Health

Hospitals are reporting more patients with breathing problems, throat infections and eye irritation. Children, older people, pregnant women and people with asthma or heart disease are most at risk, and long-term exposure to fine particles is linked to heart and lung disease.

• Wear a well-fitting mask outdoors, preferably N95.
• Avoid morning walks and outdoor exercise when the AQI is high.
• Keep windows closed during peak smog hours and limit unnecessary travel.
• Keep children and elderly family members indoors as much as possible.
• Drink plenty of water and see a doctor if coughing or breathlessness gets worse.

What Happens Next

Smog usually stays heavy until rain or stronger winds clear the air. Residents are advised to check live AQI readings before going out, and to follow any instructions from the Punjab government and the Environment Protection Department as the Lahore smog season continues.
