Air quality in NJ typically returns to normal within 1-2 weeks after Canadian wildfires, depending on weather conditions.

Estimated Duration: 14 days

Air quality recovery after wildfires depends on factors like wind patterns, rainfall, and fire containment. Canadian wildfire smoke can linger for days to weeks, but NJ's air quality usually improves within 1-2 weeks as winds disperse pollutants and rain helps clear particulate matter. Monitoring local air quality indexes (AQI) and following health advisories during this period is recommended. Prolonged effects are rare unless fires persist or weather patterns stagnate.
