Chiang Mai - 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?
The air quality is fine nine months out of the year, but quite bad between Feb and April as fields are cleared by burning. Being in a valley and with no rain during that time, the smoke just hangs around. Air quality for those three months is bad enough to require wearing a mask whenever you leave the house and running air filters 24/7 inside. School will keep the kids indoors for recess during this time. It can definitely affect people, especially anyone already susceptible to respiratory issues. - Mar 2019
