San Juan - Post Report Question and Answers
What is the air quality like at post (good/moderate/bad)? Are there seasonal air quality issues? Does the air quality have an impact on health?
It's fine as far as I could tell. A lot of people talked about the haze from African sand but I didn't notice so much. - Jan 2014
The air quality is good to moderate, unless there is a sandstorm in Africa that then blows over here. It has only happened once or twice while we were here. The sea winds usually blow pollution away. Given how damp it is, there is a great deal of mold and mildew on the island and many people have had respiratory issues. Colds can be hard to shake. - Jun 2013
