Wildfire smoke from Canada can reach NYC within 1-3 days depending on wind patterns and distance.

Estimated Duration: 3 days

The time it takes for wildfire smoke from Canada to affect NYC's air quality depends on factors like wind speed, direction, and the proximity of the fires. Typically, smoke can travel hundreds of miles within 1-3 days, leading to hazy skies and reduced air quality in NYC. Monitoring air quality indexes (AQI) and weather forecasts can help track the impact. Wildfire smoke contains fine particulate matter (PM2.5), which poses health risks, so staying informed and taking precautions is advisable when smoke is present.
