The dominant influence on Irákleion's air quality is vehicle traffic and the busy port/ferry terminal, layered onto a setting on Crete's northern coast at the foot of the Cretan mountains within Kríti. Ventilation here depends heavily on wind and rainfall, with the calmest, most stagnant periods generally producing the least favourable readings.
