Worst air pollution Casco Antiguo (Murcia) - Murcia, today and tomorrow

On 9 August 2026, overall air quality in Casco Antiguo (Murcia) is fair. AQI is the main air quality indicator at 32.2/100. Pollution peaks around 3:00 PM (O3: 32.2/100).

On 10 August 2026, air quality conditions in Casco Antiguo (Murcia) will be similar to today, with AQI forecast at fair at 37.0/100. Pollution peaks around 2:00 PM (O3: 37.0/100).

How does air quality change throughout the year in Casco Antiguo (Murcia)? The year's lowest air quality readings tend to cluster in winter, when high-pressure systems suppress the mixing that would otherwise clear away exhaust and smoke. Spring is typically when conditions begin improving, as increasing wind speeds help disperse traffic emissions before they can accumulate. The long, hot days of summer favour ozone build-up, which can spike on the stillest, sunniest afternoons. The transition into autumn generally brings cleaner conditions, as more frequent rainfall and lower temperatures curb ozone formation. Coastal sea breezes here usually aid dispersal, but summer visitor traffic and periodic dust intrusions from North Africa can still cause spikes.

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.
