How Flint Air Quality Shifts Through the Year
Mar–May: Usually Flint's cleanest stretch. Mild temperatures and better atmospheric mixing keep both ozone and particulates down.
Jun–Aug: Heat and sunlight drive higher ozone and, in the West, wildfire-smoke episodes. Afternoons are typically the worst time to be outside.
Sep–Nov: Air quality generally improves as temperatures drop, though early fall can still carry wildfire smoke in the Great Lakes region.
Dec–Feb: Cold-air temperature inversions can trap PM2.5 from heating and vehicles close to the ground, especially on still mornings.
Seasonal patterns above describe how pollution typically behaves in this region. They are not measured 2024 averages for Flint.
