6. How does the weather in Ontario affect air quality?
Weather directly impacts air quality in Ontario. Calm winds, high humidity, fog, and high pressure trap pollutants near the ground, worsening AQI. Strong winds, rainfall, and low pressure help disperse them. Rising temperatures and UV levels intensify ozone and smog formation, while poor visibility signals elevated particulate matter. Monitoring weather alongside AQI gives the clearest picture of outdoor safety.
