At Walmer, vehicle traffic and mixed farming and light industrial activity are the main local sources of emissions in this transitional Eastern Cape climate zone. Moderate rainfall through most of the year generally supports reasonable dispersal, with only occasional still mornings allowing pollution to briefly build up. Similar patterns show up in most nearby Eastern Cape towns.

When is air pollution at its worst in Walmer?
Walmer's poorest air quality usually comes in the drier winter season, when lower rainfall allows emissions from mixed farming and light industrial activity to build up more than usual. From spring, increasing rain generally helps clear the air through the remainder of the year, a seasonal pattern typical of this Eastern Cape climate zone.
Are air quality levels in Walmer 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.
