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

Estimated Duration: 14 days

After wildfires, air quality recovery depends on wind patterns, rainfall, and fire containment. Wildfire smoke can linger for days to weeks, but normal air quality usually returns within 1-2 weeks once the smoke clears. Monitoring local air quality indexes (AQI) and weather forecasts helps track improvements. Staying indoors, using air purifiers, and avoiding outdoor activities during peak pollution can minimize health risks. Long-term air quality restoration may take longer if fires persist or weather patterns stagnate.
