Worst air pollution Arona, today and tomorrow

On 19 July 2026, overall air quality in Arona is fair. PM2.5 is the main pollutant at 33.0/100. Pollution peaks around 1:00 PM (PM10: 44.3/100).

On 20 July 2026, air quality conditions in Arona will be similar to today, with PM2.5 forecast at fair at 37.8/100. Pollution peaks around 3:00 AM (PM10: 44.6/100).

Does air quality in Arona vary by season? Winter is generally the most challenging season, since low wind speeds and temperature inversions prevent traffic and wood-smoke pollution from dispersing. 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. The long, hot days of summer favour ozone build-up, which can spike on the stillest, sunniest afternoons. Autumn usually sees a steady return to cleaner conditions as the ozone-favouring heat of summer fades and rainfall picks up. Thanks to the trade winds, conditions here vary less through the year than on the mainland, though Saharan dust intrusions remain an occasional disruption regardless of season.

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.
