Howick lies roughly 90 km west-northwest of Durban. At Howick, vehicle traffic and dairy and forestry farming operations are the dominant local emission sources in this cooler, elevated Midlands setting. Winter mornings can see brief temperature inversions concentrate pollution, while the wetter, windier summer months generally restore clearer air. Similar patterns show up in most nearby Midlands towns.

When is air pollution at its worst in Howick?
Howick's poorest air quality usually comes on dry winter mornings, when temperature inversions briefly concentrate emissions from dairy and forestry farming operations nearby. Conditions generally improve from spring onward as the wetter, windier summer months return to the Midlands region, a seasonal pattern typical of the wider Midlands region.
Are air quality levels in Howick 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.
