Air quality can vary significantly in Sydney due to factors like traffic, industrial activity, and weather conditions. Typically, air quality is monitored using the Air Quality Index (AQI), which measures pollutants such as particulate matter and nitrogen dioxide. While specific percentages of "bad" air can fluctuate daily, on average, Sydney experiences good to moderate air quality, with poor air quality days occurring primarily during bushfire events or high pollution episodes. For the most accurate and current information, it's best to refer to local environmental monitoring agencies.
