Worst air pollution Sierra Nevada Ski Resort - Granada, today and tomorrow

On 9 August 2026, overall air quality in Sierra Nevada Ski Resort is fair. AQI is the main air quality indicator at 30.0/100. Pollution peaks around 2:00 AM (O3: 30.0/100).

On 10 August 2026, air quality conditions in Sierra Nevada Ski Resort will be similar to today, with AQI forecast at fair at 35.5/100. Pollution peaks around 4:00 PM (O3: 35.5/100).

What is the yearly air quality pattern like in Sierra Nevada Ski Resort? Air quality is typically at its weakest in December and January, when cold, calm high-pressure spells trap traffic exhaust and wood-smoke close to the ground instead of letting it disperse. Spring is typically when conditions begin improving, as increasing wind speeds help disperse traffic emissions before they can accumulate. Summer's combination of intense sun and high temperatures makes ozone the main concern, occasionally compounded by wildfire smoke during dry, windy spells. By late autumn, air quality is usually back to more moderate levels, though the first cold snaps can bring an early hint of winter's traffic and heating pollution. Southern Spain's high summer temperatures, combined with periodic dust blown in from North Africa, tend to sharpen the seasonal contrasts here.

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.
