What affects air quality for runners in Sydney
Sydney often benefits from ocean-influenced airflow, but local air quality still shifts with traffic intensity and weather patterns. Road corridors and tunnel approaches show stronger nitrogen dioxide peaks during commuting periods. In inland suburbs, weaker afternoon ventilation can allow particulate pollution to linger longer than in exposed coastal districts.
