Sao Paulo - Post Report Question and Answers
Pollution index (Good, Moderate, Unhealthy, or Very Unhealthy)?
Moderate, some people claim it"s extremely bad but I"ve not had any problems at all. Like any big city, it"s gray and no blue skies. - Oct 2008
Moderate. Some people complain a lot about it, but I don't think it's that bad. It rains frequently, so that tends to wash away the pollution. Much better here than Los Angeles. - Aug 2008
