Why Is the Air Quality Bad Today in NYC?
Weather plays a big role in how the air quality is in NYC each day. The amount of sun can affect how much ozone there is, and wind and rain can affect PM2.5 and particulate air pollution to varying degrees.

Below shows how PM2.5 air quality levels around the world tend to vary throughout the day. PM2.5 levels have a tendency to be slightly lower in the afternoon compared to other times of the day. But this is a general trend, New York City PM2.5 AQI levels will not follow this trend every day.
How Wildfires Out West Affect NYC’s Air Pollution Levels
Outside of weather, wildfires are another factor that can significantly affect New York City’s air quality. The worst wildfires typically occur in the months of June to September.
