Bethal's air quality reflects the Mpumalanga Highveld agricultural and energy production corridor, with vehicle traffic on the N17 and the proximity to the Matla and Duvha coal-fired power stations generating elevated regional background SO₂ and PM2.5. Winter Highveld temperature inversions concentrate power station plumes and vehicle emissions across the plateau, while the elevated 1,608-metre Highveld position aids background dispersal on windy summer days and the power station corridor dominates regional background throughout the year.

Frequently Asked Questions

Is air quality bad in Bethal right now?

On 9 August 2026, overall air quality in Bethal is poor. AQI is the main air quality indicator at 63.7/100. Pollution peaks around 11:00 AM (SO2: 63.7/100).

Will air quality be worse tomorrow in Bethal?

On 10 August 2026, air quality conditions in Bethal will be better than today, with PM1 forecast at fair at 27.9/100. Pollution peaks around 12:00 AM (SO2: 45.0/100).

When is air pollution at its worst in Bethal?

At Bethal, the poorest air quality usually occurs on still winter mornings from May to August, when smoke and vehicle emissions accumulate under a low temperature inversion typical of the Highveld plateau. From November onward, summer rains and afternoon winds generally restore clearer conditions that last through much of the warmer part of the year.

Are air quality levels in Bethal 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.
