Worst air pollution Vaalwater, today and tomorrow

On 9 August 2026, overall air quality in Vaalwater is fair. AQI is the main air quality indicator at 35.7/100. Pollution peaks around 4:00 PM (O3: 35.7/100).

On 10 August 2026, air quality conditions in Vaalwater will be similar to today, with AQI forecast at fair at 21.5/100. Pollution peaks around 1:00 PM (O3: 21.5/100).

Dry winter conditions bring the worst air quality to Vaalwater, as smoke and dust tied to citrus and subtropical farming operations linger without rain to settle them. Once summer arrives around November, regular thunderstorms and stronger winds generally restore clearer conditions across the surrounding bushveld, a seasonal pattern typical of the broader bushveld region.

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.
