Wellington's air quality in South Africa reflects the Cape Winelands Berg River valley, with vehicle traffic on the N1 national road and the surrounding wine, fruit, and logistics operations contributing local sources. The surrounding Hawequa and Groenberg mountains create topographic variation, while the Cape Doctor southeasterly periodically provides powerful ventilation from the Cape Peninsula and the Berg River valley's agricultural landscape and mountain backdrop generally maintain moderate to good conditions throughout most of the year.

When is air pollution at its worst in Wellington?
At Wellington, occasional poor air quality tends to occur on calm winter days from June to August, when the Cape's usual wind drops off and local emissions can build up overnight around the town. Through spring and summer, the reliable southeasterly wind returns and generally keeps particulate levels low and well dispersed across the wider region.
Are air quality levels in Wellington 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.
