How Pittsburgh Air Quality Changed by Season in 2022
Spring (Mar–May): Usually Pittsburgh's cleanest stretch, with AQI near 58. Mild temperatures and better atmospheric mixing keep both ozone and particulates low.
Summer (Jun–Aug): AQI climbs toward 84 as heat and sunlight drive higher ozone and, in the West, wildfire-smoke episodes. Afternoons are the worst time to be outside.
Fall (Sep–Nov): Air quality generally improves as temperatures drop, though early fall can still carry wildfire smoke in the Mid-Atlantic region.
Winter (Dec–Feb): AQI near 96. Cold-air temperature inversions can trap PM2.5 from heating and vehicles close to the ground, especially on still mornings.
