Throughout June, the Northeast region of the United States has experienced the air quality impacts of the ongoing wildfires in Canada. The air quality index (AQI), a measure of pollutants and other air quality metrics has fluctuated significantly in Norwalk as a result of the wildfires. In recent days, Norwalk's Air Quality Index (AQI) level has varied between the Green/Good and Yellow/Moderate Levels on the Air Quality Index (AQI).
Air quality levels are likely to fluctuate throughout each day. While the air quality has improved, the situation may change based on changes in wind patterns and the ability to control or stop the wildfires in Canada. Therefore, it’s important to monitor air quality regularly and be prepared to take precautions as the situation changes.
If air quality worsens, closing doors and windows can help keep the smoke out of homes and businesses. N95 and KN95s can help filter smoke, so you can consider wearing those outdoors if/when the air quality is poor.
You can find updates about the air quality in our area as well as recommendations and links for more information by visiting Norwalk's Air Quality data dashboard.
