The air quality index (AQI) for New York City is currently 100, according to AirGov.

Here is a closer look at what the numbers represent:

  • 0-50: Good, with little to no risk of pollution.
  • 51-100: Moderate and really is not a risk to anyone unless they're unusually sensitive to poor air quality. The national weather service will often still issue an air quality alert when we're in this range.
  • 101-150: This is a risk for sensitive groups and people with asthma.
  • 151-200: A risk for everyone and people who are sensitive are at risk for more severe complications.
  • 201-300: Very unhealthy and a risk for everyone.
  • 301+: Emergency conditions.
