Guayaquil's air quality reflects the flat Ecuadorian Guayas River delta coastal position, with vehicle traffic on surrounding roads and the port, industrial, and vehicle density corridor generating elevated PM2.5 and NOₓ. Consistent Pacific maritime breezes and the Humboldt Current's coastal ventilation provide relief, while the rainy season's convective rain provides effective cleansing and Guayaquil generally maintains moderate Ecuadorian Pacific coastal economic capital readings throughout most of the year.
