Worst air pollution Candelaria, today and tomorrow

On 19 July 2026, overall air quality in Candelaria is fair. PM2.5 is the main pollutant at 30.0/100. Pollution peaks around 2:00 PM (PM10: 43.1/100).

On 20 July 2026, air quality conditions in Candelaria will be similar to today, with O3 forecast at fair at 28.6/100. Pollution peaks around 4:00 AM (PM10: 46.3/100).

What time of year has the cleanest air in Candelaria? Winter mornings are frequently the year's most polluted, as fog and calm conditions trap traffic fumes and smoke from wood stoves close to the ground. 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. High summer temperatures and strong sun exposure drive ozone levels up, occasionally combined with smoke from nearby wildfires during dry 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. The islands' mild, trade-wind-driven climate means seasonal swings are gentler than on the mainland, but calima dust events can occur in any month.

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.
