The remaining pollutants stay at good levels. Based on Airmine's forecast, which uses satellite data to calculate exposure every 200 metres along the route, air quality is at its worst 0.0 km after start. Pollen exposure peaks at 0.0 km after start.

Seville Marathon runs through the historic Seville city streets and along the Guadalquivir River, with olive, orange, and plane as the main tree pollen sources along the urban route. The February race date falls during the early Mediterranean pollen season when olive is beginning to peak, while cypress contributes from January through spring and surrounding Andalusian olive groves and cereal farmland contribute substantial olive and grass pollen throughout this classic flat Andalusian river city marathon.

Frequently Asked Questions
Where is air quality worst on the Seville Marathon route?
Based on today's forecast, O3 is forecast at fair levels along the route today (31.9/100). Air quality is at its worst after 0.0 km into the route. Airmine calculates exposure at 200m intervals along the course using satellite-derived atmospheric data.
Where is pollen highest on the Seville Marathon course?
Pollen exposure peaks at km 0.0 today. This changes through the season as different pollen species become active.
When is pollen worst during the Seville Marathon season?
February coincides with peak grass season. Grass pollen typically rises in May-June.
How often is this forecast updated?
Updated four times daily. See the timestamp below for the most recent update.
Are pollen levels in Seville Marathon based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Seville Marathon, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
Levels show the highest exposure along the full route. Airmine uses satellite data to calculate pollen and air quality every 200 metres along each race route, updated four times daily.
