Read this article about CDMX air quality in 1978. I was there briefly then and can attest to the problem. I remember walking by the Palacio des Bellas Artes and literally choking. I was a smoker then and it was impossible to smoke because the air was so polluted. Lol but not really.
On our most recent visit, the air was not noticeably polluted however due to the elevation of 2240 m above sea level, the air is thinner. One can get winded pretty easily when climbing a hill or several sets of stairs.
Another peculiarity is that there are no visible bugs like flys, bees or mosquitoes in CDMX, at least when we were there in March. Why is this so? Well here is the answer.
We had our windows open with no screens and never a bug or fly did we see. Same in Nuevo Vallarta. We leave our screen free balcony door open 24/7 and only extremely rarely would a fly or bee be seen inside the condo.
So another nice thing about Mexico – no bugs for the most part. However there are no see ems on the beach that bite that Marie can attest to. Hasta luego.
