Shanwei's air quality benefits from its exceptional Guangdong eastern coastal position on the South China Sea, with consistent South China Sea trade winds providing reliable maritime ventilation. Vehicle traffic on surrounding expressways and the nuclear energy, fisheries, and manufacturing corridor contribute local sources, while the nuclear plants' essentially zero direct combustion emissions and the outstanding coastal exposure maintain Shanwei among Guangdong's more moderately ventilated eastern coastal cities.

Frequently Asked Questions
Is air quality bad in Shanwei right now?
On 10 August 2026, overall air quality in Shanwei is very poor. AQI is the main air quality indicator at 100/100. Pollution peaks around 3:00 PM (O3: 100/100).
Will air quality be worse tomorrow in Shanwei?
On 11 August 2026, air quality conditions in Shanwei will be similar to today, with AQI forecast at very poor at 100/100. Pollution peaks around 1:00 PM (O3: 100/100).
When is air pollution at its worst in Shanwei?
Air quality in Shanwei tends to be worse when traffic emissions together with manufacturing activity build up and onshore breezes fall calm. Maritime airflow normally ventilates the area well, though calmer spells let levels rise. This natural ventilation is one reason coastal areas often see better readings than inland cities.
Are air quality levels in Shanwei 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.
