Worst air pollution Florida - Johannesburg, today and tomorrow
Today (9 August): Air quality in Florida is poor. AQI, HCHO, and PM1 are poor; PM10 and NO2 are fair; PM2.5, O3, and SO2 are medium; CO is good. Pollution peaks around 2:00 AM (HCHO: 68.2/100).
Tomorrow (10 August 2026): Air quality in Florida is fair. AQI improves to fair; PM2.5 increases to fair; PM10 decreases to good; NO2 decreases to good; O3 increases to fair; SO2 decreases to good; HCHO decreases to fair; PM1 decreases to fair; all other pollutants stay as today. Pollution peaks around 9:00 AM (PM1: 31.6/100). Airmine updates local air quality forecasts four times daily.

Florida lies roughly 10 km west of Johannesburg. Florida deals with the same basic air quality drivers as most Highveld towns: vehicle traffic and government, finance, and commercial operations, both of which matter most on calm winter mornings when a low inversion holds emissions close to the ground. Summer generally undoes this with stronger, more consistent winds. The wider Highveld region generally follows this same rough pattern.

Frequently Asked Questions
Is air quality bad in Florida right now?
On 9 August 2026, overall air quality in Florida is poor. AQI is the main air quality indicator at 68.2/100. Pollution peaks around 2:00 AM (HCHO: 68.2/100).
Will air quality be worse tomorrow in Florida?
On 10 August 2026, air quality conditions in Florida will be better than today, with AQI forecast at fair at 31.6/100. Pollution peaks around 9:00 AM (PM1: 31.6/100).
When is air pollution at its worst in Florida?
Winter is the tricky season for air quality at Florida, with calm mornings letting emissions from government, finance, and commercial operations build up under a typical Highveld inversion. Once the rainy season starts around November, conditions generally improve and stay that way into early autumn. This is a familiar pattern across much of the Highveld.
Are air quality levels in Florida 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.
