Guangzhou Air Quality — Live AQI & Pearl River Delta Outlook

Guangzhou sits at the heart of one of the world's largest manufacturing regions, where traffic, port logistics, and industrial activity contribute to PM2.5 and ozone episodes. Regional haze can persist across the delta during weak-wind periods.

Humid summers support photochemical smog, while autumn and winter may bring sharper particle spikes when inversions trap emissions. Typhoon rains and strong southerly flows often improve conditions within hours.

Hourly AQI monitoring helps plan outdoor work, school commutes, and exercise around cleaner windows. Avoiding major expressways during rush hour reduces exposure even when citywide averages look moderate.
