Sydney generally enjoys excellent air quality thanks to ocean breezes and limited heavy industry. However, bushfire season can bring hazardous smoke, as dramatically demonstrated in the 2019-2020 fires. The harbor and coastal paths provide world-class running environments with typically clean air.
Sydney typically sees AQI values between 15 and 40, among the cleanest of major world cities. Bushfire smoke events (typically November-February) can temporarily spike readings above 200.
Autumn and winter (March-August) offer excellent running conditions with clean air and mild temperatures. The Bondi to Coogee coastal walk and harbor paths are ideal. Monitor bushfire smoke conditions in summer.
