San Juan de los Lagos's air quality reflects the flat Jalisco Los Altos plateau at 1,800 metres, with vehicle traffic on surrounding roads and the religious pilgrimage tourism, food processing, and agricultural corridor contributing local sources. The elevated plateau position aids dispersal on most days, while winter inversions create modest seasonal challenges and San Juan de los Lagos generally maintains moderate Mexican western Jalisco highland plateau readings throughout most of the year.
