Worst air pollution Logroño, today and tomorrow

On 9 August 2026, overall air quality in Logroño is fair. AQI is the main air quality indicator at 34.0/100. Pollution peaks around 2:00 PM (O3: 34.0/100).

On 10 August 2026, air quality conditions in Logroño will be similar to today, with AQI forecast at fair at 33.4/100. Pollution peaks around 7:00 PM (O3: 33.4/100).

What is the yearly air quality pattern like in Logroño? Winter high-pressure systems tend to produce the year's worst episodes, as still air traps traffic fumes and heating smoke at ground level. The transition into spring usually brings cleaner air, as more frequent rain and wind reduce the buildup of local pollution. Summer's combination of intense sun and high temperatures makes ozone the main concern, occasionally compounded by wildfire smoke during dry, windy spells. Conditions generally improve through autumn as cooling temperatures reduce ozone formation and returning rains help disperse remaining pollutants. Inland locations like this typically see harsher winter inversions and hotter summer ozone spikes than areas closer to the coast.

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.
