Worst air pollution Deusto - Bilbao, today and tomorrow

On 19 July 2026, overall air quality in Deusto is fair. AQI is the main air quality indicator at 31.3/100. Pollution peaks around 3:00 PM (O3: 31.3/100).

On 20 July 2026, air quality conditions in Deusto will be similar to today, with AQI forecast at fair at 38.2/100. Pollution peaks around 5:00 PM (O3: 38.2/100).

What is the yearly air quality pattern like in Deusto? 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 usually brings an improvement as more frequent rain and stronger winds help clear the air and wash out pollutants that built up over winter. Summer can bring periodic wildfire smoke on top of the usual ozone build-up from intense heat and sunshine. Conditions tend to stabilise in autumn, as cooling weather and increasing rain reduce the ozone spikes typical of summer. Frequent Atlantic weather systems mean pollution rarely has the chance to accumulate for long stretches in this area.

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.
