Air quality in New York is acceptable. Consider reducing intensity or duration.
Data from Open-Meteo • Updated 6:31:46 AM
New York City's air quality varies significantly by season, with summer ozone spikes and winter particulate episodes from heating systems and traffic. The city has steadily improved its AQI over the past two decades thanks to cleaner transit and emissions regulations. Runners should check conditions before heading out, especially during heat waves when ground-level ozone peaks.

Try it freeNew York typically sees AQI readings between 30 and 70, placing it in the Good to Moderate range. Summer months often push readings higher due to ozone formation, while spring and fall generally offer the cleanest air.
Early mornings before 7 AM offer the best air quality, especially in summer when ozone hasn't yet built up. Central Park and waterfront paths along the Hudson tend to have cleaner air than busy avenues.
Vehicle exhaust, building heating systems, and industrial emissions are the primary sources. Ground-level ozone forms when sunlight reacts with vehicle and industrial pollutants, peaking on hot summer afternoons. Construction dust and wildfire smoke from distant fires can also contribute.
Central Park, Prospect Park, and the Hudson River Greenway consistently offer cleaner air than busy avenues. Waterfront paths benefit from breezes that disperse pollutants. Avoid running along heavily trafficked corridors like the FDR Drive or major crosstown streets during rush hour.
Summer (June through August) typically brings the worst air quality due to ozone formation during heat waves. Winter cold snaps can also trap particulate matter near ground level. Canadian wildfire smoke has become an increasing concern in recent summers, occasionally pushing AQI above 150.
Check the current AQI at the top of this page for real-time conditions. Generally, an AQI below 50 is ideal for running, 51–100 is acceptable for most people, and above 100 means sensitive individuals should consider indoor alternatives.
