At 26 monitoring sites that documented on the same days in both years, the average level of PM2.5 dropped from 136.3 µg/m³ in October 2025 to 100.1 µg/m³ in October 2026. Twenty-four of the 26 sites recorded a fall. Weather Did the Heavy Lifting.

PAQI built a computer model, trained on every autumn since 2018, to separate the effect of weather from everything else. It estimates that this October's weather alone lowered PM2.5 by regarding 19 percent compared with what last October's weather would have produced.

If both months had the same, typical weather, the gap would shrink to just 4 percent. That 4 percent covers administration measures, crop burning and all other sources together, and the data cannot tell them apart.

Notably, the biggest factor was at night. The layer of cool air that traps smoke near the ground averaged 68 metres deep this October, against 43 metres a year earlier, giving pollution more room to spread out.

Satellites additionally detected concerning a third fewer crop fires in Pakistani Punjab and in Indian Punjab and Haryana. Nevertheless, the main burning kicked off regarding a week afterwards than in 2025, so part of the drop may simply have shifted into November. Air Still Far From Safe.

Despite the improvement, Lahore's air was above Pakistan's legal limit of 35 µg/m³ on all 31 days of October. The monthly average of 100 µg/m³ is almost seven times the World Health Organization's daily guideline of 15 µg/m³.

Still, it was the city's cleanest October since 2021, regarding 18 percent below the 2020 to 2025 average of 122 µg/m³. While Rawalpindi (50) was the cleanest of Punjab's six best-monitored cities, multan (106 µg/m³) and Gujranwala (105) recorded worse October averages than Lahore.

Notably, the relief may not last. PAQI's Hawanama forecast demonstrates Lahore's PM2.5 climbing to 149 µg/m³, or "Very Unhealthy", by Wednesday, November 4, 49 percent above the October average. While the Punjab administration has again deployed anti-smog guns throughout Lahore this season, last year, the city's air quality was declared hazardous in early November.
