Across 2020, Syracuse's median AQI was around 52 (Moderate), based on current readings and seasonal patterns for the Syracuse reporting area. That means a typical day fell near AQI 52, with the dominant pollutant being ground-level ozone (O3), which is common for the Northeast region.
How Syracuse Air Quality Changed by Season in 2020
Spring (Mar–May): Usually Syracuse's cleanest stretch, with AQI near 34. Mild temperatures and better atmospheric mixing keep both ozone and particulates low.
Summer (Jun–Aug): AQI climbs toward 76 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 54. Cold-air temperature inversions can trap PM2.5 from heating and vehicles close to the ground, especially on still mornings.

Reduce Indoor Ozone in Syracuse
Today's main pollutant in Syracuse is ground-level ozone (AQI 48). 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.
