New York, NY (May 18, 2026)

New York City is under an Air Quality Health Advisory today, with state environmental officials forecasting pollution levels that may be unhealthy for sensitive groups.

The New York State Department of Environmental Conservation issued the advisory after the Air Quality Index was forecast to reach Code Orange, which means AQI levels between 101 and 150. At that level, most healthy people face a low risk from outdoor activity, but those more vulnerable to air pollution may experience health effects.

Sensitive groups include adults over 65, children under 14, pregnant individuals, outdoor workers, and people with heart disease, lung disease, asthma, or other respiratory conditions.

Officials are urging those at higher risk to reduce strenuous outdoor activities, take extra breaks while outside, and watch for symptoms such as coughing, wheezing, chest tightness, or shortness of breath. People with asthma or chronic lung conditions should keep quick-relief medication available and follow their regular care plans.

The advisory is in effect for Monday, May 18. Residents are encouraged to monitor local air quality throughout the day and adjust outdoor plans as needed, especially during periods of heavier exertion or prolonged time outside.

Schools, camps, workplaces, and community organizations with outdoor activities may also consider limiting strenuous activity for children, seniors, and others at increased risk until conditions improve.
