How New York Air Quality Changed by Season in 2024
Spring (Mar–May): Usually New York's cleanest stretch, with AQI near 23. Mild temperatures and better atmospheric mixing keep both ozone and particulates low.
Summer (Jun–Aug): AQI climbs toward 65 as heat and sunlight drive ozone formation to its yearly peak. 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 Northeast region.
Winter (Dec–Feb): AQI near 43. Cold-air temperature inversions can trap PM2.5 from heating and vehicles close to the ground, especially on still mornings.

Reduce Indoor Ozone in New York
Today's main pollutant in New York is ground-level ozone (AQI 37). Important: standard HEPA filters do NOT remove ozone — only a purifier with a substantial activated-carbon bed adsorbs it. The biggest wins are cutting indoor sources (gas appliances, certain "ionizer" purifiers) and ventilating when outdoor ozone is low (early morning). A high-carbon unit helps with the gases and VOCs that linger indoors.
