Loulé's air quality benefits from its inland Algarve position at 160 metres in the Barrocal limestone hills, with consistent Atlantic and Mediterranean sea breezes from the nearby Faro coast providing reliable maritime ventilation. Vehicle traffic on the A22 Via do Infante and surrounding almond, carob, and tourism operations contribute local sources, while the Atlantic coastal proximity and the Algarve's consistently sunny and breezy climate maintain generally good conditions throughout the year.
