Worst air pollution Torre del Reloj (Cartagena) - Cartagena, today and tomorrow

On 20 September 2026, overall air quality in Torre del Reloj (Cartagena) is fair. AQI is the main air quality indicator at 28.9/100. Pollution peaks around 8:00 AM (PM2.5: 28.9/100).

On 21 September 2026, air quality conditions in Torre del Reloj (Cartagena) will be similar to today, with AQI forecast at fair at 31.8/100. Pollution peaks around 11:00 AM (PM2.5: 31.8/100).

When is air quality typically worst in Torre del Reloj (Cartagena)? The winter months typically bring the weakest air quality of the year, as calm anticyclonic conditions trap vehicle and heating pollution near the surface. Air quality usually improves through spring, helped by more frequent frontal systems that bring rain and stronger winds to disperse local emissions. Hot, stagnant summer air favours ozone formation, and dry vegetation nearby occasionally adds wildfire smoke to the mix during peak heat. Early autumn can still bring warm, stagnant spells before the season's returning rain and wind begin clearing the air. Sea breezes along this stretch of coast generally support air quality, but summer holiday traffic and occasional calima dust events can interrupt that.

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.

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.
