Fernkloof Nature Reserve lies roughly 100 km southeast of Cape Town. Fernkloof Nature Reserve's coastal Garden Route position means sea breezes generally provide reliable ventilation, with vehicle traffic and tourism and forestry operations contributing the bulk of local emissions. Even on calmer days, the area's mild, wet climate usually prevents pollution from building up significantly. It's a fairly standard picture for this part of the coastline.

When is air pollution at its worst in Fernkloof Nature Reserve?
Consistent onshore wind keeps air quality steady at Fernkloof Nature Reserve across most of the year, with emissions from tourism and forestry operations rarely building up for long. The only brief dips come during unusually calm, windless spells, which clear again within a day or so, a seasonal pattern typical of the wider Garden Route coastline.
Are air quality levels in Fernkloof Nature Reserve 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.
