What affects air quality for runners in Singapore
Singapore's air quality is generally moderated by maritime airflow and frequent rainfall, yet urban emissions still shape local daily patterns. Traffic corridors and industrial zones can produce short-lived peaks, especially during high activity periods. Because the island is compact, weather shifts can quickly improve or worsen conditions across broad areas.
