Phoenix lies roughly 20 km north of Durban. Vehicle traffic and port and industrial operations shape most of the local air quality picture at Phoenix, moderated by the steady Indian Ocean sea breeze typical of this stretch of coast. The area's humid subtropical climate keeps conditions generally favourable year-round. Much of the surrounding coastline sees broadly the same seasonal pattern.

Frequently Asked Questions
Is air quality bad in Phoenix right now?
On 20 September 2026, overall air quality in Phoenix is poor. AQI is the main air quality indicator at 63.5/100. Pollution peaks around 11:00 PM (PM1: 63.5/100).
Will air quality be worse tomorrow in Phoenix?
On 21 September 2026, air quality conditions in Phoenix will be worse than today, with AQI forecast at very poor at 81.9/100. Pollution peaks around 11:00 AM (PM1: 81.9/100).
When is air pollution at its worst in Phoenix?
Air quality at Phoenix is generally stable year-round thanks to consistent Indian Ocean sea breezes, though hot, still, humid days in mid-summer can occasionally allow haze and emissions from port and industrial operations to build up before the breeze returns. Winter typically brings the clearest conditions, a seasonal pattern typical of the broader KwaZulu-Natal coast.
Are air quality levels in Phoenix 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.
