Worst air pollution Wolmaransstad, today and tomorrow

On 9 August 2026, overall air quality in Wolmaransstad is fair. PM1 is the main pollutant at 23.5/100. Pollution peaks around 1:00 PM (O3: 41.8/100).

On 10 August 2026, air quality conditions in Wolmaransstad will be better than today, with AQI forecast at good at 19.0/100. Pollution peaks around 11:00 PM (SO2: 19.0/100).

The worst air quality at Wolmaransstad shows up on calm winter mornings, when emissions tied to maize, sunflower, and grain farming operations settle under the kind of low inversion that's common across the Highveld. That pattern breaks once the summer rains and stronger winds arrive from November onward. This is a familiar pattern across much of the Highveld.

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.

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.
