New York City is experiencing degraded air quality due to smoke from wildfires burning in Canada and the Great Lakes region. The city's Office of Emergency Management issued an Air Quality Health Advisory, with pollution levels reaching "Unhealthy for Sensitive Groups" on Wednesday.
Air quality is expected to remain in the 101-150 range on the Air Quality Index (AQI) through Wednesday evening. This level is a significant improvement from the "Hazardous" peak of 465 recorded in June 2023, when smoke from Canadian wildfires turned the sky orange. Despite the improvement, officials are monitoring the situation.
This smoke event coincides with an ongoing heat wave, with temperatures projected to approach 100 degrees Fahrenheit. The city has activated its heat emergency plan. Officials noted that if the smoke intensifies, it could potentially lower temperatures by blocking sunlight.
NYC Emergency Management Commissioner Christina Farrell advised residents to be aware of their personal risk profiles. "If you're sensitive to air quality, don't remain in a space without air conditioning or filtration," Farrell stated. "And if you're in a population vulnerable to heat, older adults, young children, people with chronic conditions, take the heat seriously too."
She recommended seeking cool indoor spaces, including designated cooling centers, for those vulnerable to either poor air quality or high temperatures.
Wildfires have affected other parts of the United States as well. At least 17 fires have burned thousands of acres across Minnesota, with the five largest fires consuming at least 30,000 acres. Some U.S. fires, such as the Bear Trap and Thumb fires, have spread across the border into Canada, contributing to the smoke impacting the northeastern United States.
