Puerto del Rosario's air quality is shaped mostly by Saharan dust intrusions and port and shipping activity. Air quality is usually good, but can deteriorate sharply during dust episodes. Calima events, when Saharan dust sweeps in, are by far the biggest local air-quality concern.

When is air pollution at its worst in Puerto del Rosario?
Does air quality in Puerto del Rosario vary by season? January is frequently the most difficult month, with cold stagnant air allowing wood-smoke and exhaust to build up instead of clearing. Spring often marks a turning point, with increasing storminess and rainfall helping to clear accumulated exhaust and smoke from the air. 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. 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.
Are air quality levels in Puerto del Rosario based on measurements or forecasts?
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.
Why doesn’t the forecast always reflect wildfire impacts?
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.
