San Andrés Tuxtla's air quality reflects the Veracruz volcanic highland's Tuxtla massif position at 287 metres, with vehicle traffic on surrounding roads and the tobacco, citrus, and agricultural corridor contributing local sources. The surrounding Sierra de los Tuxtlas volcanic rises create topographic variation, while the tropical climate's frequent rain provides effective atmospheric cleansing and San Andrés generally maintains moderate southern Veracruz volcanic highland readings throughout most of the year.
