Local Environmental Conditions
Around the heart of Jerez de la Frontera, dense development means road traffic is the main local source of nitrogen dioxide and fine particles. Breezes off the Bay of Cadiz usually help ventilate the area. On some days, pollution drifting in from farther away outweighs local sources. Levels are generally highest right next to busy roads and drop off quickly with distance.
From June to October, strong sunshine and temperatures around 26°C drive ozone formation, with levels peaking in the afternoon. In contrast, air near roads is often at its worst from December to February, when nights cool to around 13°C and the air turns still. Overall, stronger winds around February, about 20 km/h on average, usually bring some of the cleanest air of the year.

When is air pollution at its worst in Jerez de la Frontera?
From June to October, strong sunshine and temperatures around 26°C drive ozone formation, with levels peaking in the afternoon. In contrast, air near roads is often at its worst from December to February, when nights cool to around 13°C and the air turns still. Overall, stronger winds around February, about 20 km/h on average, usually bring some of the cleanest air of the year.
Are air quality levels in Jerez de la Frontera 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.
Understanding the Scale
The 0–100 air quality scores represent risk levels, not direct air pollutant concentrations. Higher scores indicate higher risk.
Air Quality
| Good | 0-20 | Low air quality risk. Air quality is expected to be good, with low levels of pollution. |
| Fair | 20-40 | Generally low air quality risk. Air quality is expected to be acceptable, with some pollution present. |
| Moderate | 40-60 | Moderate air quality risk. Air pollution is elevated and air quality may be less favorable. |
| Poor | 60-80 | High air quality risk. Air pollution is high and air quality is expected to be poor. |
| Very Poor | 80-100 | Very high air quality risk. Air pollution is very high and air quality is expected to be very poor. |
