Évora's air quality benefits from its elevated Alentejo plateau position at 309 metres, with consistent Atlantic and prevailing westerly winds across the open Alentejo plain providing generally good background dispersal. Vehicle traffic on the A6 motorway and surrounding cork, wine, and agricultural operations contribute the primary local sources, while the open Alentejo plains and Atlantic westerlies generally prevent significant pollution accumulation in this UNESCO heritage Roman and Moorish university city throughout most of the year.
