Santo Domingo Tehuantepec's air quality reflects the flat Oaxacan Tehuantepec Isthmus position adjacent to the famous Tehuano wind corridor, with vehicle traffic on surrounding roads and the wind energy, fishing port, and agricultural corridor contributing local sources. The extraordinary Tehuano wind provides among Mexico's most powerful natural urban ventilation, while the wind energy infrastructure's operations represent a distinctively clean industrial contribution throughout most of the year.
