Beihai's air quality benefits from its exceptional Guangxi Beibu Gulf coastal position, with consistent South China Sea and Beibu Gulf trade winds providing outstanding maritime ventilation along this famous Beihai Silver Beach coast. Vehicle traffic on surrounding expressways and the tourism, fisheries, and petrochemical corridor contribute local sources, while the outstanding tropical coastal exposure generally maintains Beihai among Guangxi's cleaner coastal cities throughout most of the year.

Frequently Asked Questions

Is air quality bad in Beihai right now?

On 10 August 2026, overall air quality in Beihai is poor. AQI is the main air quality indicator at 64.1/100. Pollution peaks around 4:00 AM (O3: 64.1/100).

Will air quality be worse tomorrow in Beihai?

On 11 August 2026, air quality conditions in Beihai will be worse than today, with AQI forecast at very poor at 100/100. Pollution peaks around 3:00 PM (O3: 100/100).

When is air pollution at its worst in Beihai?

The biggest local contributors to pollution in Beihai are traffic emissions, heavy industry such as steel, cement, or petrochemical processing, along with tourism-related traffic, particularly once maritime winds die down. Maritime airflow normally ventilates the area well, though calmer spells let levels rise. Areas further inland without this ventilation tend to fare worse.

Are air quality levels in Beihai based on measurements or forecasts?

It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.

Why doesn’t the forecast always reflect wildfire impacts?

Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.

During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
