Equestria lies roughly 60 km north-northeast of Johannesburg. Air quality at Equestria is shaped by its Highveld plateau setting, where vehicle traffic and government, finance, and commercial operations are the main local sources of particulate pollution. Dry winter mornings often see temperature inversions trap emissions near the surface, while summer rains and afternoon winds typically improve dispersal conditions. This mirrors what's typical for towns across the wider plateau region.

Frequently Asked Questions
Is air quality bad in Equestria right now?
On 9 August 2026, overall air quality in Equestria is fair. PM1 is the main pollutant at 31.4/100. Pollution peaks around 2:00 PM (O3: 41.9/100).
Will air quality be worse tomorrow in Equestria?
On 10 August 2026, air quality conditions in Equestria will be similar to today, with AQI forecast at fair at 26.5/100. Pollution peaks around 3:00 PM (O3: 26.5/100).
When is air pollution at its worst in Equestria?
The dry Highveld winter brings the worst air quality to Equestria, as calm mornings let emissions from government, finance, and commercial operations linger close to the ground. Once summer rains arrive around November, stronger winds and regular storms typically clear the air across the wider plateau, a seasonal pattern typical of the wider Highveld plateau.
Are air quality levels in Equestria 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.
