Worst air pollution Vryheid, today and tomorrow

On 9 August 2026, overall air quality in Vryheid is poor. AQI is the main air quality indicator at 72.2/100. Pollution peaks around 10:00 AM (SO2: 72.2/100).

On 10 August 2026, air quality conditions in Vryheid will be better than today, with PM1 forecast at fair at 39.7/100. Pollution peaks around 12:00 AM (SO2: 41.3/100).

Air quality at Vryheid is most likely to dip during the dry winter months, when cool, still mornings allow temperature inversions to briefly trap emissions from dairy and forestry farming operations. Conditions generally improve from spring onward as summer rains and stronger winds return, a seasonal pattern typical of the wider Midlands 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.
