Worst air pollution Los Realejos, today and tomorrow

On 19 July 2026, overall air quality in Los Realejos is fair. O3 is the main pollutant at 27.1/100. Pollution peaks around 2:00 PM (PM10: 40.7/100).

On 20 July 2026, air quality conditions in Los Realejos will be similar to today, with PM2.5 forecast at fair at 38.3/100. Pollution peaks around 4:00 AM (PM10: 43.4/100).

What is the yearly air quality pattern like in Los Realejos? Winter is generally the most challenging season, since low wind speeds and temperature inversions prevent traffic and wood-smoke pollution from dispersing. March through May tends to see steady improvement, with more unsettled weather patterns helping disperse traffic and heating pollution. Hot, stagnant summer air favours ozone formation, and dry vegetation nearby occasionally adds wildfire smoke to the mix during peak heat. Autumn typically starts mild and can still see occasional ozone or dust episodes before rain and cooler temperatures gradually restore cleaner conditions. The Canary Islands' subtropical trade-wind climate keeps conditions milder year-round, though Saharan dust intrusions (calima) can arrive at any time of year and briefly dominate.

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.
