Air pollution is a problem all over Thailand, but in the burning season (usually Feb - April) the pollution in Chaing Mai gets particularly bad as there is no wind to take the smoke away. 

During this time, the Health Office and Athletic Department closely monitor pollution levels throughout the day by checking the Air Quality Index (AQI). From this, we are able to make decisions about any activity restrictions at school. 

CMIS Air Quality Standards and Activity Level Guidelines are aligned with the Environmental Production Agency of the US Government are included below. 

We have included a live display of the current air quality for the area around CMIS.
