How Yonkers Air Quality Shifts Through the Year
Mar–May: Usually Yonkers's cleanest stretch. Mild temperatures and better atmospheric mixing keep both ozone and particulates down.

Sep–Nov: Air quality generally improves as temperatures drop, though early fall can still carry wildfire smoke in the Northeast region.
Dec–Feb: Cold-air temperature inversions can trap PM2.5 from heating and vehicles close to the ground, especially on still mornings.
