The effects of Canada wildfires on NYC air quality can be felt within 24 to 48 hours, depending on wind patterns.

Estimated Duration: 1 days

Wildfire smoke from Canada can travel long distances due to atmospheric conditions. When winds are favorable, smoke particles and pollutants can reach New York City within 1-2 days, leading to hazy skies, reduced visibility, and potential health impacts. Monitoring air quality indexes (AQI) and weather reports helps track these changes. The speed depends on wind direction, intensity of wildfires, and atmospheric stability. Sensitive groups may notice effects sooner, while widespread impacts typically manifest within two days.
