Orkney lies roughly 160 km southeast of Mahikeng. Air quality at Orkney is shaped by its Highveld plateau setting, where vehicle traffic and gold mining and processing 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 Orkney right now?

On 16 July 2026, overall air quality in Orkney is fair. PM2.5 is the main pollutant at 38.5/100. Pollution peaks around 8:00 AM (SO2: 50.1/100).

Will air quality be worse tomorrow in Orkney?

On 17 July 2026, air quality conditions in Orkney will be similar to today, with O3 forecast at fair at 30.7/100. Pollution peaks around 11:00 PM (SO2: 53.1/100).

When is air pollution at its worst in Orkney?

The dry Highveld winter brings the worst air quality to Orkney, as calm mornings let emissions from gold mining and processing 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 Orkney 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.
