Air quality in NYC typically returns to normal within a few days to a week after wildfire smoke dissipates, depending on weather conditions.
Estimated Duration: 7 days
The duration for NYC's air quality to normalize after Canada wildfires depends on factors like wind patterns, rainfall, and fire containment. Wildfire smoke can linger for days, but improved air quality usually follows within a week if fires are controlled and weather aids dispersion. Monitoring air quality indexes (AQI) and following local health advisories is recommended during such events. Prolonged exposure to wildfire smoke can have health impacts, so staying indoors with air purifiers can help mitigate risks until conditions improve.
