Vientiane - 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?
Air quality is quite good for 10-11 months of the year. In February/March, it can get very bad as fields (both in Laos and neighboring Thailand) are burned in preparation for planting. - Jun 2020
Unsure. I think its better than most major SE Asian cities, but there's not good data. The suspicion is that during the dry season, it will be worse because of the burning of trash. - Oct 2018
The air quality was between moderate and unhealthy, and can depend on where you live. We were in an area with more expats so we did not have as much garbage burning as some other parts did. Motorbikes are plenty. There is not a lot of heavy industry, so you do not have the smog you would expect from China. - Jan 2014
