Mataró's air quality reflects its position on the Maresme Costa coast northeast of Barcelona, with consistent Mediterranean sea breezes providing reliable maritime ventilation along this Catalan coastal city. Vehicle traffic on the C-32 coastal motorway and the surrounding textile and electronics manufacturing industry contribute the primary local sources, while the Serralada Litoral hills immediately inland create topographic variation, and the Barcelona sea breeze cycle generally provides adequate afternoon ventilation across the Maresme coastal corridor throughout most of the year.

When is air pollution at its worst in Mataró?
What time of year has the cleanest air in Mataró? The coldest months usually see the year's poorest conditions, since calm anticyclonic weather holds local traffic and wood-burning pollution near street level. Conditions tend to ease in spring, as more active weather systems bring the wind and rain needed to disperse ground-level pollution. Summer's combination of intense sun and high temperatures makes ozone the main concern, occasionally compounded by wildfire smoke during dry, windy spells. Autumn is typically a recovery period, with increasing rainfall and cooler air gradually reducing both ozone and traffic-related pollution. The Mediterranean coast's sea breezes generally help disperse pollution, though summer tourism traffic and occasional Saharan dust can still push levels up.
Are air quality levels in Mataró 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.
