At Parkhurst, vehicle traffic and government, finance, and commercial operations are the dominant local sources shaping air quality on the Highveld plateau. Calm winter mornings allow emissions to build up under a low inversion layer, while the arrival of summer rains and stronger winds generally restores clearer conditions. Similar patterns show up in most Highveld towns of a similar size.

Frequently Asked Questions
Is air quality bad in Parkhurst right now?
On 9 August 2026, overall air quality in Parkhurst is poor. AQI is the main air quality indicator at 75.5/100. Pollution peaks around 2:00 AM (SO2: 75.5/100).
Will air quality be worse tomorrow in Parkhurst?

When is air pollution at its worst in Parkhurst?
Parkhurst sees its poorest air quality on windless winter mornings, when a low temperature inversion traps local emissions and those from government, finance, and commercial operations nearby. Summer's arrival from November brings stronger winds and thunderstorms that usually restore clearer conditions for months at a time, a seasonal pattern typical of the wider Highveld plateau.
Are air quality levels in Parkhurst 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.
