Bayeux's air quality in Brazil reflects the greater João Pessoa metropolitan area in Paraíba, with vehicle emissions from the BR-230 and surrounding urban and light industrial character of this densely populated João Pessoa satellite municipality contributing elevated NOₓ. Atlantic trade winds from the Paraíba coast provide background maritime ventilation, generally maintaining moderate readings throughout most of the year in this northeastern Brazilian coastal metropolitan corridor.
