High olive pollen levels forecast for Aranjuez

Pollen is the story here — specifically olive and grass pollen — and the practical stakes are simple. If you’re sensitive, a normal day outdoors in and around Madrid can turn into sneezing, itchy eyes, blocked sinuses, or worse. What changed on Wednesday, May 6, is that the Community of Madrid flagged high levels for Aranjuez and several other zones, telling allergy sufferers to take precautions and stay on top of their treatment.

For olive pollen, the high-risk list included Alcobendas, Aranjuez, Getafe, and the Madrid districts of Arganzuela and Salamanca. Coslada and Ciudad Universitaria were marked at medium risk for olive. (20minutos.es) ### Why is Aranjuez in this? Aranjuez is one of the municipalities covered by the regional pollen-monitoring network, so it is not being named casually. Madrid’s PALINOCAM network uses 11 sampling stations across the region, including Aranjuez, Alcobendas, Getafe, Coslada, and several Madrid districts. That matters because these alerts are tied to local measurements and short-range forecasts, not just a generic “high pollen in Madrid” headline. (transparencia.madrid.es) ### Why olive pollen now?

The advice was not dramatic, but it was clear — take preventive measures and follow prescribed treatment.

The Community of Madrid said its 2026 pollen alert campaign stays active until June 30, which means more olive, grass, and plantago updates are still ahead as (20minutos.es)s your day.
